Javascript 替换对象'；在运行时使用dupliacte值的s键 var myNewKeyNames=['asas'，'asas']； var obj=[{key:'value'，key:'value'}] 对于（var i=0；i

来说，我不太明白您想要什么…但是尝试了一下。查看下面的链接

据我所知：

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
    }
}

var myNewKeyNames=['new_-key1'，'new_-key2']；
var obj=[{key1:'value1'，key2:'value2'}]；
对于（var i=0；i

请尝试更清楚地描述您的问题，并对代码进行重新格式化。@DotNET Ninja:完成，请检查上述内容。我可以像这样在新键1之间留有空格吗？如果我这样做，我该怎么办

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]);
    }
}
