js对json的处理
JSON字符串：
var jsonStr = ‘{"name":"nikita", "password":"1111"}‘;
JSON对象：
var jsonObj = {"name":"nikita", "password":"1111"};
var last = JSON.stringify(jsonObj); //将JSON对象转化为JSON字符
JSON.parse(jsonStr); //可以将json字符串转换成json对象
eval(‘(‘ + jsonstr + ‘)‘); //可以将json字符串转换成json对象,注意需要在json字符外包裹一对小括号
注：ie8(兼容模式),ie7和ie6也可以使用eval()将字符串转为JSON对象，但不推荐这些方式，这种方式不安全eval会执行json串中的表达式。
