从WebMethod返回值到javascript [英] Return value from WebMethod to javascript

问题描述

我有Jquery部分，用于在c#中调用Web方法.

< script type ="text/javascript">
$(document).ready(function(){
$(''#btnLoadUserCtrl'').click(function(){
var ControlName =〜/sample.ascx";
alert(ControlName);
$ .ajax({
类型:"POST"，
网址:"sample.aspx/结果"，
数据:"{controlName:""+ ControlName +"''}，
contentType:"application/json; charset = utf-8"，
dataType:"json"，
成功:功能(响应){
警报(响应);
$(''#uControl'').html(response);
}，
失败:功能(msg){
alert("msasdas");
alert(msg);
$(''#uControl'').html(msg);
}
});
});
});
</script>

在此返回字符串值的webMethod中，执行功能后，它到达了jquery的成功部分，但返回了空值..

I have the Jquery part for call the web method in c#

<script type="text/javascript">
$(document).ready(function () {
$(''#btnLoadUserCtrl'').click(function () {
var ControlName = "~/sample.ascx";
alert(ControlName);
$.ajax({
type: "POST",
url: "sample.aspx/Result",
data: "{controlName:''" + ControlName + "''}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
alert(response);
$(''#uControl'').html(response);
},
failure: function (msg) {
alert("msasdas");
alert(msg);
$(''#uControl'').html(msg);
}
});
});
});
</script>

In this webMethod that returns the string value , After the excecution of function, it came to the success section of jquery, but returns null value..

推荐答案

(document) .ready(function(){

(document).ready(function () {

(``#btnLoadUserCtrl'').click(function(){
var ControlName =〜/sample.ascx";
alert(ControlName);

(''#btnLoadUserCtrl'').click(function () {
var ControlName = "~/sample.ascx";
alert(ControlName);

.ajax({
类型:"POST"，
网址:"sample.aspx/结果"，
数据:"{controlName:""+ ControlName +"''}，
contentType:"application/json; charset = utf-8"，
dataType:"json"，
成功:功能(响应){
alert(response);

.ajax({
type: "POST",
url: "sample.aspx/Result",
data: "{controlName:''" + ControlName + "''}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
alert(response);
