Q1: jquery解析json字符串格式为[{data:[{userid:'10001',username:'chen'}],totalCount:2}]?

var  str = "[{data:[{userid:'10001',username:'chen'}],totalCount:2}]";

var obj = eval("(" + str + ")");

console.log(obj[0].data[0].userid);

console.warn(obj[0].data[0].username);

console.debug(obj[0].totalCount);

Q2: jquery怎样解析json字符串？

你好！

解析成数组是指，将json中的值取出来存放到数组中么？

也许下面代码能给你点帮助：

$(document).ready(function(){

    var obj = jQuery.parseJSON('{"jobID":"020000715","username":"\u9a6c\u94f6\u534e","department":"\u7ee7\u7eed\u5b66\u9662"}');

    var myData=[];       //定义一个数组变量

    $.each(obj,function(key,value){

        myData.push(value);

    });

    alert(myData);

});
