如何使用javascript / jquery从数组中过滤数据？
[英]How to filter the data from array using javascript/jquery?
问题描述
I have declared an array as var user_profile = []; 
我已将数组声明为var user_profile = []; and I have already some pushed data in array which contains : 我已经在数组中包含一些推送数据，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
}
]
I only need the data in array whose assessCatId=1,2,3 and assessReason is not Empty . 我只需要其assetCatId = 1,2,3的数组中的数据， 并且assessReason不为Empty 。 So I tried by filtering it: 所以我尝试通过过滤它：
const output = user_profile.filter(({ assessCatId,assessReason }) => assessCatId != 0 || assessReason != 'empty');
console.log("here the outpuit is");
console.log(output) ;
But it is not filtering the array.Still every data is coming in the array.How can i manage this array to filter the data? 但是它不是在过滤数组。仍然每个数据都在数组中。我如何管理这个数组来过滤数据？

You have to use && instead of || 您必须使用&&而不是|| . 。 Try 尝试
(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) ;
You can also shortened the condition like 您也可以缩短条件
(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);

You can insert any value in array and check it 您可以在数组中插入任何值并检查它
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)

You can do assessCatId > 0 && assessReason 您可以执行assessCatId > 0 && assessReason
Code: 码：
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);

Just replace by ({ assessCatId,assessReason })=>assessCatId>0 && assessReason!='') 只需替换为({ 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);

I think you should first try the basic
for loopthen you should dive to the array helper/prototype functions.for loop然后再深入研究数组帮助器/原型功能。 This will help you to understand whats going on.
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()))

Use a filter function and use second this parameter to pass array of CatIds. 使用过滤器函数，然后使用第二个this参数传递CatIds数组。 Test that the current element's id is included in the CatIds and use the fact that defined, non-empty strings are truthy, falsey otherwise. 测试当前元素的ID是否包含在CatId中，并使用已定义的非空字符串为true，否则为false的事实。
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);

Use && instead of || 使用&&代替|| because in the case of &&, true is returned when both the conditions are true whereas in the case of || 因为在&&的情况下，当两个条件都为true时返回true，而在||的情况下则返回true true is returned if either of the conditions is true. 如果任一条件为true，则返回true。 Since in your case you want both assessCatId!=0 and assessReason= not empty, So for this && will work. 由于在您的情况下，您既需要assetCatId！= 0，又要使assetReason =不为空，所以对于此&&就可以了。
Code Snippet 代码段
(assessCatId >= 1 && assessCatId <= 3) && (assessReason != '' && assessReason != null) （assessCatId> = 1 && AssessmentCatId <= 3）&&（assessReason！=''&& AssessmentReason！= null）
