如何将json数组推送到json数组？

Question

我现有的来自响应的json数组是：

comments:[{id: "3124fac5-9d3e-4fa9-8a80-10f626fbf141", createdDate: 1469606019000,…},…]
0:{id: "3124fac5-9d3e-4fa9-8a80-10f626fbf141", createdDate: 1469606019000,…}
createdBy:{id: "cf2829b7-0c76-4a08-9562-ccbfa012ef2d", createdDate: 1469605771000, name: "user",…}

我想将json的文件数组推送到json的现有注释数组，json的结果应如下所示：

comments:[{id: "3124fac5-9d3e-4fa9-8a80-10f626fbf141", createdDate: 1469606019000,…},…]
0:{id: "3124fac5-9d3e-4fa9-8a80-10f626fbf141", createdDate: 1469606019000,…}
createdBy:{id: "cf2829b7-0c76-4a08-9562-ccbfa012ef2d", createdDate: 1469605771000, name: "user",…}
createdDate:1469606019000
id:"3124fac5-9d3e-4fa9-8a80-10f626fbf141"
lastModifiedBy:{id: "cf2829b7-0c76-4a08-9562-ccbfa012ef2d", createdDate: 1469605771000, name: "user",…}

Answer 1

您只需要向jsonObject添加一个属性即可。 您只需要了解如何使用JavaScript向JSON对象添加新属性（元素）

yourCurrentJSONObject.propertyNameToAdd = yourFilesArray;

例

var yourCurrentJSONObject = {
comments:[{id: "3124fac5-9d3e-4fa9-8a80-10f626fbf141", createdDate: 1469606019000,…},…]
0:{id: "3124fac5-9d3e-4fa9-8a80-10f626fbf141", createdDate: 1469606019000,…}
createdBy:{id: "cf2829b7-0c76-4a08-9562-ccbfa012ef2d", createdDate: 1469605771000, name: "user",…}
createdDate:1469606019000
id:"3124fac5-9d3e-4fa9-8a80-10f626fbf141"
lastModifiedBy:{id: "cf2829b7-0c76-4a08-9562-ccbfa012ef2d", createdDate: 1469605771000, name: "user",…}
lastModifiedDate:1469606019000
message:"twrey"
1:{id: "350fd2bd-f452-495c-9bd5-79aa7c799d02", createdDate: 1469619161000,…}
createdBy:{id: "cf2829b7-0c76-4a08-9562-ccbfa012ef2d", createdDate: 1469605771000, name: "user",…}
createdDate:1469619161000
id:"350fd2bd-f452-495c-9bd5-79aa7c799d02"
lastModifiedBy:{id: "cf2829b7-0c76-4a08-9562-ccbfa012ef2d", createdDate: 1469605771000, name: "user",…}
lastModifiedDate:1469619161000
message:"yuo"
}


var yourFilesArray = [....];
yourCurrentJSONObject['files'] = yourFilesArray;
//    or simply
yourCurrentJSONObject.files = yourFilesArray;    

如果您可以按照上述说明操作阵列，您将看到它包括带有注释和消息的文件阵列alog

如果您有两个对象数组，并且想要合并它们，则可以使用Array.map（）和Object.assign（） 。

当然，两个数组的长度必须相同

 var a = [{id: 1, asd: 2}, {id: 2, asd: 3}]; var b = [{files: 'asd'}, {files: 'dsa'}]; var c = a.map((obj, i) => Object.assign(obj, b[i])); console.log(c)
