记下笔记：jQuery遍历json的方法

var obj = {"status":1,"bkmsg":"\u6210\u529f","bkdata":["\u5415\u5c1a\u5fd7","1387580400","\u6dfb\u52a0\u8bb0\u5f55"]}{"status":1,"bkmsg":"\u6210\u529f","bkdata":["\u5415\u5c1a\u5fd7","1387580400","\u6dfb\u52a0\u8bb0\u5f55"]},{"status":1,"bkmsg":"\u6210\u529f","bkdata":["\u5415\u5c1a\u5fd7","1387580400","\u4ec0\u4e48\u4e5f\u6ca1\u6709"]} 

$.ajax({ 
url: '/path/to/file', 
type: 'GET', 
dataType: 'json', 
data: {param1: 'value1'}, 
success: function (obj){

// console.log(obj.length); 
if (obj.status == 1) { 
for (var i = 0; i < obj.bkdata.length; i++) { 
console.log(obj.bkdata[i]); 
}; 
}else{

//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。

} 
//元素 each方法
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{

}; 
//jquery each方法
