ajax请求：
$.ajax({ ????????url: ‘/path/to/file‘, ????????type: ‘GET‘, ????????dataType: ‘json‘, ????????data: {param1: ‘value1‘}, ????????success: function (obj){ ?????????????//遍历obj ????????} ????}) ?返回的内容在success的函数里面，所有的遍历操作都是在这里面操作的：
for循环：
var obj = { ????????"status":1, ????????"bkmsg":"\u6210\u529f", ????????"bkdata":["\u5415\u5c1a\u5fd7","1387580400","\u6dfb\u52a0\u8bb0\u5f55"] ????} ???// console.log(obj.length); ????if (obj.status == 1) { ????????for (var i = 0; i < obj.bkdata.length; i++) { ????????????console.log(obj.bkdata[i]); ????????}; ????}else{ ????????alert("数据有误~"); ????}; ?for in 循环：
//for in循环 ????for(x in obj.bkdata){ ????????//x表示是下标，来指定变量，指定的变量可以是数组元素，也可以是对象的属性。 ????????console.log(obj.bkdata[x]); ????} ?//元素 each方法
if (obj.status == 1) { ????????$(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{ ????????alert("数据有误~"); ????}; ?//jquery each方法
$.each( obj.bkdata, function(index,item){ ????????console.log(item); ????}); ?jquery 如何遍历json
