如何将一项推入包含15个对象的数组

Question

var array1 = [{
  "candidateId": 57,
  "firstName": "Sumit",
  "lastName": "Kumar Gupta",
  "displayName": "Sumit1",
  "locked": false,
  "photoId": -1,
  "resumeId": -1,
  "experience": " 6 Months",
  "email": "sumit1@test.com",
  "mobile": "+91.8100688592",
  "preferredLocation": [
    "Bangalore"
  ],
  "currentEmployer": [

  ],
  "skills": [{
    "skillName": "JAVA",
    "level": "advanced",
    "candidateRating": "5",
    "rating": 0
  }],
  "viewed": true,
  "nextStates": [{
    "state": "Approach"
  }]]


var array2 = [image1]

我从其他请求获取array2图像，所以我分配给array2 。 现在，我想将此array2推送或添加到array1 。 所以我创建了一个对象

'image'  
array2.push({'image':image1})

并尝试推动

for(var i=0; i<array1.length;i++){
  array1[i].push(array2[i]);
}

但这没用。

Answer 1

array1[i]['image'] = image1; 或array1[i].image = image1;

您需要使用属性访问器将图像对象添加到array1值。

演示

 var array1 = [{ "candidateId": 57, "firstName": "Sumit", "lastName": "Kumar Gupta", "displayName": "Sumit1", "locked": false, "photoId": -1, "resumeId": -1, "experience": " 6 Months", "email": "sumit1@test.com", "mobile": "+91.8100688592", "preferredLocation": [ "Bangalore" ], "currentEmployer": [ ], "skills": [{ "skillName": "JAVA", "level": "advanced", "candidateRating": "5", "rating": 0 }], "viewed": true, "nextStates": [{ "state": "Approach" }] }] for (var i = 0; i < array1.length; i++) { array1[i]['image'] = 'image1'; } console.log(array1) 

Answer 2

如果要映射两个长度相等的数组，其中每个索引位置的对象都将被合并，则可以map其中一个数组，并使用传播语法对对象进行浅表复制和合并。 如果任何一个输入数组都需要保持不变，这种方法将有助于防止副作用。

该代码将是：

array1.map((obj, i) => ({...obj, image: array2[i]}));

和一个演示：

 var array1 = [{ "candidateId": 57, "firstName": "Sumit", "lastName": "Kumar Gupta", "displayName": "Sumit1", "locked": false, "photoId": -1, "resumeId": -1, "experience": " 6 Months", "email": "sumit1@test.com", "mobile": "+91.8100688592", "preferredLocation": [ "Bangalore" ], "currentEmployer": [ ], "skills": [{ "skillName": "JAVA", "level": "advanced", "candidateRating": "5", "rating": 0 }], "viewed": true, "nextStates": [{ "state": "Approach" }] }]; var array2 = ["image1"]; var combined = array1.map((obj, i) => ({...obj, image: array2[i]})); console.log(combined); 

Answer 3

似乎您正在尝试访问数组2中比可用索引更多的索引。

尝试：

for(var i=0; i<array1.length;i++){
  array1[i].push(array2[0]);
}
