    var array = [
        {
            id:1,
            name:"小明"
        },
        {
            id:2,
            name:"小红"
        }
    ];
    
    /**/
    //旧key到新key的映射
    var keyMap = {
        "id" : "value",
        "name" : "label"
    };
    
    for(var i = 0;i < array.length;i++){
            var obj = array[i];
            for(var key in obj){
                       var newKey = keyMap[key];
                       if(newKey){
                                obj[newKey] = obj[key];
                                delete obj[key];
                         }
                }
    }
