Ajax发送数据及接受数据（接口及json数据解析）
Ajax传输轻量数据（JSON数据格式）前台发送
function push() {
$.ajax({
url: "http://",//对方接受地址
data: {'data':'<%=ss%>'},//传输数据
type: "POST",//传输方式
datatype: "json",//数据格式
success: function (result) {//接受返回值，用于判断是否传输成功
var dataObj = eval("(" + result + ")");//解析返回值（这里我返回的是一个json数据）｛”errocode ”: “0”｝
if (dataObj.errocode == 0)//分析返回数据
{
alert("推送成功！");
}
alert(result);
},
error: function (err, ex) {
alert("查询失败！");
}
});

文中用到的数据JSON数据格式（组合式数据类型）
"{ card_no: '1000000001', 'order_no': '1000000001', 'pay_type': 1,'send_people': { 'send_name': '张赛', 'send_mobile': '12345678901', 'blessing': [ { 'message': '祝你生日', 'tpl': '12345678901' }，{ 'message': '祝你生日', 'tpl': '12345678901' }], 'reciever': { 'id': 'name', 'mobile': '1234567', 'address': '莲花街道', 'batch': '1'}";
本文提到传输组合式json数据亦可用这样的方式组成（根据自己的需求，灵活运用），再进行传输。
Ajax和JSON数据的解析，日常中是常用到的，本人一个入门的程序员，不对之处能给与改正。
