如何使用javascript / jquery從數組中過濾數據？

Question

我已將數組聲明為var user_profile = []; 我已經在數組中包含一些推送數據，其中包含：

[  
   {  
      "assessmentType":"FINAL",
      "assessCatId":-1,
      "assessReason":"2",
      "assessAmount":"",
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":-1,
      "assessReason":"2",
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":-1,
      "assessReason":"",
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":0,
      "assessReason":null,
      "assessAmount":"",
      "assessPenalty":"",
      "assessTotal":0
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":0,
      "assessReason":null,
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":0,
      "assessReason":"",
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":0,
      "assessReason":"",
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":0,
      "assessReason":"2075-09-09",
      "assessAmount":"2075-09-17",
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":0,
      "assessReason":"2075-09-09",
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":0,
      "assessReason":"2075-09-17",
      "assessTotal":null
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":1,
      "assessReason":"",
      "assessAmount":"0",
      "assessPenalty":"0",
      "assessTotal":0
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":2,
      "assessReason":"",
      "assessAmount":"0",
      "assessPenalty":"0",
      "assessTotal":0
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":3,
      "assessReason":"",
      "assessAmount":"0",
      "assessPenalty":"0",
      "assessTotal":0
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":1,
      "assessReason":"A",
      "assessAmount":"1",
      "assessPenalty":"2",
      "assessTotal":3
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":2,
      "assessReason":"B",
      "assessAmount":"3",
      "assessPenalty":"4",
      "assessTotal":7
   },
   {  
      "assessmentType":"FINAL",
      "assessCatId":3,
      "assessReason":"C",
      "assessAmount":"5",
      "assessPenalty":"6",
      "assessTotal":11
   }
]

我只需要其assetCatId = 1,2,3的數組中的數據， 並且assessReason不為Empty 。 所以我嘗試通過過濾它：

const output = user_profile.filter(({ assessCatId,assessReason })  => assessCatId != 0 || assessReason != 'empty');
            console.log("here the outpuit is");
            console.log(output)  ;

但是它不是在過濾數組。仍然每個數據都在數組中。我如何管理這個數組來過濾數據？

Answer 1

您必須使用&&而不是|| 。 嘗試

(assessCatId >= 1 && assessCatId <= 3) && (assessReason != '' && assessReason != null)

 var user_profile =[ { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessAmount":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessAmount":"", "assessPenalty":"", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessAmount":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"A", "assessAmount":"1", "assessPenalty":"2", "assessTotal":3 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"B", "assessAmount":"3", "assessPenalty":"4", "assessTotal":7 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"C", "assessAmount":"5", "assessPenalty":"6", "assessTotal":11 } ] const output = user_profile.filter(({ assessCatId,assessReason }) => (assessCatId >= 1 && assessCatId <= 3) && (assessReason != '' && assessReason != null)); console.log("here the outpuit is"); console.log(output) ; 

您也可以縮短條件

(assessCatId >= 1 && assessCatId <= 3) && assessReason)

 var user_profile =[ { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessAmount":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessAmount":"", "assessPenalty":"", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessAmount":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"A", "assessAmount":"1", "assessPenalty":"2", "assessTotal":3 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"B", "assessAmount":"3", "assessPenalty":"4", "assessTotal":7 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"C", "assessAmount":"5", "assessPenalty":"6", "assessTotal":11 } ] const output = user_profile.filter(({ assessCatId,assessReason }) => (assessCatId >= 1 && assessCatId <= 3) && assessReason); console.log("here the outpuit is"); console.log(output); 

Answer 2

您可以在數組中插入任何值並檢查它

 let k=[ { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessAmount":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessAmount":"", "assessPenalty":"", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessAmount":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"A", "assessAmount":"1", "assessPenalty":"2", "assessTotal":3 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"B", "assessAmount":"3", "assessPenalty":"4", "assessTotal":7 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"C", "assessAmount":"5", "assessPenalty":"6", "assessTotal":11 } ] let arr=[1,2,3] let d=k.filter(a=>arr.indexOf(a.assessCatId) > -1 && a.assessReason!="" && a.assessReason!=null) console.log(d) 

Answer 3

您可以執行assessCatId > 0 && assessReason

碼：

 const user_profile = [{"assessmentType": "FINAL","assessCatId": -1,"assessReason": "2","assessAmount": "","assessTotal": null},{"assessmentType": "FINAL","assessCatId": -1,"assessReason": "2","assessTotal": null},{"assessmentType": "FINAL","assessCatId": -1,"assessReason": "","assessTotal": null},{"assessmentType": "FINAL","assessCatId": 0,"assessReason": null,"assessAmount": "","assessPenalty": "","assessTotal": 0},{"assessmentType": "FINAL","assessCatId": 0,"assessReason": null,"assessTotal": null},{"assessmentType": "FINAL","assessCatId": 0,"assessReason": "","assessTotal": null},{"assessmentType": "FINAL","assessCatId": 0,"assessReason": "","assessTotal": null},{"assessmentType": "FINAL","assessCatId": 0,"assessReason": "2075-09-09","assessAmount": "2075-09-17","assessTotal": null},{"assessmentType": "FINAL","assessCatId": 0,"assessReason": "2075-09-09","assessTotal": null},{"assessmentType": "FINAL","assessCatId": 0,"assessReason": "2075-09-17","assessTotal": null},{"assessmentType": "FINAL","assessCatId": 1,"assessReason": "","assessAmount": "0","assessPenalty": "0","assessTotal": 0},{"assessmentType": "FINAL","assessCatId": 2,"assessReason": "","assessAmount": "0","assessPenalty": "0","assessTotal": 0},{"assessmentType": "FINAL","assessCatId": 3,"assessReason": "","assessAmount": "0","assessPenalty": "0","assessTotal": 0},{"assessmentType": "FINAL","assessCatId": 1,"assessReason": "A","assessAmount": "1","assessPenalty": "2","assessTotal": 3},{"assessmentType": "FINAL","assessCatId": 2,"assessReason": "B","assessAmount": "3","assessPenalty": "4","assessTotal": 7},{"assessmentType": "FINAL","assessCatId": 3,"assessReason": "C","assessAmount": "5","assessPenalty": "6","assessTotal": 11}]; const output = user_profile.filter(({assessCatId, assessReason}) => assessCatId > 0 && assessReason); console.log(output); 

Answer 4

嘗試這個：

var res = arr.filter( el => el.assessCatId > 0 && el.assessCatId < 4 && el.assessReason  ) ;

 var arr = [ { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessAmount":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessAmount":"", "assessPenalty":"", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessAmount":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"A", "assessAmount":"1", "assessPenalty":"2", "assessTotal":3 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"B", "assessAmount":"3", "assessPenalty":"4", "assessTotal":7 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"C", "assessAmount":"5", "assessPenalty":"6", "assessTotal":11 } ] var res = arr.filter( el => el.assessCatId > 0 && el.assessCatId < 4 && el.assessReason ) ; console.log(res); 

Answer 5

 var arr = [{ "assessmentType": "FINAL", "assessCatId": -1, "assessReason": "2", "assessAmount": "", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": -1, "assessReason": "2", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": -1, "assessReason": "", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": null, "assessAmount": "", "assessPenalty": "", "assessTotal": 0 }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": null, "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "2075-09-09", "assessAmount": "2075-09-17", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "2075-09-09", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "2075-09-17", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 1, "assessReason": "", "assessAmount": "0", "assessPenalty": "0", "assessTotal": 0 }, { "assessmentType": "FINAL", "assessCatId": 2, "assessReason": "", "assessAmount": "0", "assessPenalty": "0", "assessTotal": 0 }, { "assessmentType": "FINAL", "assessCatId": 3, "assessReason": "", "assessAmount": "0", "assessPenalty": "0", "assessTotal": 0 }, { "assessmentType": "FINAL", "assessCatId": 1, "assessReason": "A", "assessAmount": "1", "assessPenalty": "2", "assessTotal": 3 }, { "assessmentType": "FINAL", "assessCatId": 2, "assessReason": "B", "assessAmount": "3", "assessPenalty": "4", "assessTotal": 7 }, { "assessmentType": "FINAL", "assessCatId": 3, "assessReason": "C", "assessAmount": "5", "assessPenalty": "6", "assessTotal": 11 }] var o = arr.filter((f) => [1, 2, 3].indexOf(f.assessCatId) != -1 && f.assessReason) console.log(o) 

Answer 6

只需替換為({ assessCatId,assessReason })=>assessCatId>0 && assessReason!='')

 var user_profile = [ { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessAmount":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessAmount":"", "assessPenalty":"", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessAmount":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"A", "assessAmount":"1", "assessPenalty":"2", "assessTotal":3 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"B", "assessAmount":"3", "assessPenalty":"4", "assessTotal":7 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"C", "assessAmount":"5", "assessPenalty":"6", "assessTotal":11 } ]; const output = user_profile.filter(({ assessCatId,assessReason })=>assessCatId>0 && assessReason!=''); console.log("output", output.length, output); 

Answer 7

var output = [];
for(var i=0; i < user_profile.length; i++){
    var assessCatId = user_profile[i].assessCatId;
    var assessReason = user_profile[i].assessReason;
    if((assessCatId >= 1 && assessCatId <= 3) && (assessReason != '' && assessReason != null)){
        output.push(user_profile[i]);
    }
}
console.log(output);

Answer 8

我認為您應該首先嘗試基本的for loop然后再深入研究數組幫助器/原型功能。 這將幫助您了解發生了什么。

 function test() { var data = [{ "assessmentType": "FINAL", "assessCatId": -1, "assessReason": "2", "assessAmount": "", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": -1, "assessReason": "2", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": -1, "assessReason": "", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": null, "assessAmount": "", "assessPenalty": "", "assessTotal": 0 }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": null, "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "2075-09-09", "assessAmount": "2075-09-17", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "2075-09-09", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 0, "assessReason": "2075-09-17", "assessTotal": null }, { "assessmentType": "FINAL", "assessCatId": 1, "assessReason": "", "assessAmount": "0", "assessPenalty": "0", "assessTotal": 0 }, { "assessmentType": "FINAL", "assessCatId": 2, "assessReason": "", "assessAmount": "0", "assessPenalty": "0", "assessTotal": 0 }, { "assessmentType": "FINAL", "assessCatId": 3, "assessReason": "", "assessAmount": "0", "assessPenalty": "0", "assessTotal": 0 }, { "assessmentType": "FINAL", "assessCatId": 1, "assessReason": "A", "assessAmount": "1", "assessPenalty": "2", "assessTotal": 3 }, { "assessmentType": "FINAL", "assessCatId": 2, "assessReason": "B", "assessAmount": "3", "assessPenalty": "4", "assessTotal": 7 }, { "assessmentType": "FINAL", "assessCatId": 3, "assessReason": "C", "assessAmount": "5", "assessPenalty": "6", "assessTotal": 11 } ] for (var i = 0; i < data.length; i++) { var current_node = data[i]; var filtered = []; if ((current_node.assessCatId >= 1 && current_node.assessCatId <= 3) && (current_node.assessReason != '' && current_node.assessReason != null)) { filtered.push(current_node); } } return filtered; } console.log(JSON.stringify(test())) 

Answer 9

使用過濾器函數，然后使用第二個this參數傳遞CatIds數組。 測試當前元素的ID是否包含在CatId中，並使用已定義的非空字符串為true，否則為false的事實。

 const arr = [ { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessAmount":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"2", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":-1, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessAmount":"", "assessPenalty":"", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":null, "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessAmount":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-09", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":0, "assessReason":"2075-09-17", "assessTotal":null }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"", "assessAmount":"0", "assessPenalty":"0", "assessTotal":0 }, { "assessmentType":"FINAL", "assessCatId":1, "assessReason":"A", "assessAmount":"1", "assessPenalty":"2", "assessTotal":3 }, { "assessmentType":"FINAL", "assessCatId":2, "assessReason":"B", "assessAmount":"3", "assessPenalty":"4", "assessTotal":7 }, { "assessmentType":"FINAL", "assessCatId":3, "assessReason":"C", "assessAmount":"5", "assessPenalty":"6", "assessTotal":11 } ]; const catIds = [1, 2, 3]; // return elements with acceptable catId (id matches at least one) and truthy reason (non-empty, non-null, non-undefined) function filterFn({ assessCatId: id, assessReason: reason }) { return this.includes(id) && !!reason }; const res = arr.filter(filterFn, catIds); console.log(res); 

Answer 10

使用&&代替|| 因為在&&的情況下，當兩個條件都為true時返回true，而在||的情況下則返回true 如果任一條件為true，則返回true。 由於在您的情況下，您既需要assetCatId！= 0，又要使assetReason =不為空，所以對於此&&就可以了。

代碼段

（assessCatId> = 1 && AssessmentCatId <= 3）&&（assessReason！=''&& AssessmentReason！= null）
