javascript - 在运行时用重复值替换对象的键

Question

var myNewKeyNames = ['asas','asas'];
var obj =[{key:'value',key:'value'}]
for(var i =0; i<obj.length; i++) {
     for(key in the obj[i]) {

          alert(key) // gives the keys in the object
          alert(myNewKeyNames) instead of key in the object which would rep the values
          alert(value) // gives the value in the object
    }
}

现在我可以将键转换为其他值......而不使用循环的键值。我尝试更换...像这样...但它不采取...

我不想在初始阶段重命名 key ，只是当 key 打印在textboxxx中时我想将其命名为不同的...

据我了解:

var myNewKeyNames = ['new_key1','new_key2'];
var obj =[ { key1: 'value1', key2: 'value2' } ];
for(var i = 0; i < obj.length; i++) { 
    var j = 0;
    for(key in obj[i]) {
        alert(myNewKeyNames[j++] + ': ' + obj[i][key]);
    }
}
