如何大写Javascript对象键? [英] How to uppercase Javascript object keys?

问题描述

任何人都知道改变这种状况的好方法吗?:

Anyone know a good way to turn this?:

var obj = [{key1: value1,key2: value2},{key3: value3,key4: value4}];

进入:

var obj = [{Key1: value1,Key2: value2},{Key3: value3,Key4: value4}];

推荐答案

通过删除和替换循环:

var obj = [{key1: 1,key2: 1},{key3: 1,key4: 1}];
for(var i = 0; i<obj.length;i++) {

    var a = obj[i];
    for (var key in a) {
        var temp; 
        if (a.hasOwnProperty(key)) {
          temp = a[key];
          delete a[key];
          a[key.charAt(0).toUpperCase() + key.substring(1)] = temp;
        }
    }
    obj[i] = a;

}
