如何将对象数组值附加到现有数组

Question

我添加了一个小问题，你可以解决问题http://jsfiddle.net/ro59fxow/

var myFolders = ['abc','bcd','cda']; //these values are dynamic

var a1 = myFolders[0];
var folder = {
                a1:['11'],   //this is giving a1 ,i want here abc
                folder1: ['sss','www'],
                folder2 : ['uvw','xyz']
            }

myFolders.push(folder);
console.warn(myFolders);

提前致谢

Answer 1

将第二个数组合并到第一个数组中使用以下代码。

  Array.prototype.push.apply(myFolders,folder.folder2);

输出：[“abc”，“bcd”，“cda”，“uvw”，“xyz”]

Answer 2

您可以使用以下代码，我应该理解您的问题。

    var myFolders = ['abc','bcd','cda']; //these values are dynamic

    var a1 = myFolders[0];
    console.log(a1);
    var folder = {};
    folder[a1] = ['111']; //use this syntax to evaluate the variable as a key value.

    myFolders.push(folder);
    console.warn(myFolders);
