1. for loop:

var obj = { 
    "status":1, 
    "bkmsg":"\u6210\u529f", 
    "bkdata":["\u5415\u5c1a\u5fd7","1387580400","\u6dfb\u52a0\u8bb0\u5f55"] 
} 
// console.log(obj.length); 
if (obj.status == 1) { 
    for (var i = 0; i < obj.bkdata.length; i++) { 
        console.log(obj.bkdata[i]); 
    }; 
}else{ 
    alert("数据有误~"); 
};

2. for in loop:

//for in循环 
for(x in obj.bkdata){ 
    //x表示是下标,来指定变量,指定的变量可以是数组元素,也可以是对象的属性。 
    console.log(obj.bkdata[x]); 
}

3. each method

if (obj.status == 1) { 
     $(obj.bkdata).each(function(index,item){ 
         //index指下标 
         //item指代对应元素内容 
         //this指代每一个元素对象 
         //console.log(obj.bkdata[index]); 
         console.log(item); 
         //console.log($(this)); 
    }); 
}else{ 
    alert("数据有误~"); 
};
