JQuery中的ajax怎么传参到后台

Answer 1

jquery中ajax只需配置相应的参数即可传参到后台页面。格式如下：$.ajax({&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; type: "get",//数据发送的方式（post 或者 get）&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; url: "/admin/index",//要发送的后台地址&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; data: {val1:"1",val2:"2"},//要发送的数据（参数）格式为{'val1':"1","val2":"2"}&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; dataType: "json",//后台处理后返回的数据格式&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; success: function (data) {//ajax请求成功后触发的方法&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;alert('请求成功');&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; error: function (msg) {//ajax请求失败后触发的方法&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; alert(msg);//弹出错误信息&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; });});后台接收数据（参数）<?phpval1 = $_GET['val1'];//1val2 = $_GET['val2'];//2?>
