//js 对象<script>    person[]=new Object();    person[0].firstname="Bill";    person[0].lastname="Gates";     person[1].firstname="Bill";    person[1].lastname="Gates";    //将对象转为json字符串    var jsonstr=JSON.stringify(person);    //传递给php    $.post('url',{obj:jsonstr},function(data){},'json');</script>//php 代码public function get_json(){    //获取json字符串    //注意 用thinkphp 框架 最好不要用框架自带的I方法获取数据,因为I方法在过滤字符串的同时会把字符串内部的双引号转义,导致解析json失败 返回null.此时若用json_last_error()函数获取 介绍返回提示,返回值可能是4 表示语法错误。    $str=$_POST['obj'];    //解析json    $str=json_decode($str);}
