从asp.net中的js文件调用webmethod [英] calling webmethod from js file in asp.net

问题描述

大家好
我有一个jscript文件，例如:

hi all
i have one jscript file like:

saveSticky = function saveSticky() {
	    $.ajax({
	        type: "POST",
	        url: "Home.aspx/MethodSample",
	        data: "{}",
	        contentType: "application/json; charset=utf-8",
	        dataType: "json",
	        success: function succ(msg) {
	            alert('Called Ajax Method');
	        },
	        failure: function (response) {
	            alert(response);
	        }
	    });
	  
	    var that = $(this), sticky = (that.hasClass("sticky-status") || that.hasClass("sticky-content")) ? that.parents('div.sticky') : that,
                obj = {
                    id: sticky.attr("id"),
                    top: sticky.css("top"),
                    left: sticky.css("left"),
                    text: write = sticky.children(".sticky-content").html().search(document.getElementById("lblusername").value) <= 0 ? sticky.children(".sticky-content").html() + document.getElementById("lblusername").value : sticky.children(".sticky-content").html()
                }
	    localStorage.setItem("sticky-" + obj.id, JSON.stringify(obj));

	    sticky.find(".sticky-status").text("saved");
	    // alert('end to save stickey sticky-' + obj.id + ' ' + JSON.stringify(obj));
	}

是调试脚本代码，它工作正常，我在运行代码时未收到任何错误，但
jquery方法不会每次都调用webmethod
我的网络方法就像:

am debug script code it works fine i did''t get any errors while running code but
jquery method wont calling webmethod every time
my web method is like:

[WebMethod]
   public static void MethodSample()
   {
       string str = "Hello World";
   }

这样我就尝试调用像这样的方法:

so that i tried calling method like:

url: "organozation/Home.aspx/MethodSample"

但再次它无法正常工作，我尝试使用其他类型的分配，但没有得到结果，所以我如何在这里调用Web方法...
任何人都可以帮我吗..
在此先感谢

but again it wont working i tried allot with different type but am not getting result so how can i call web method here...
can any one please help me..
thanks in advance

推荐答案

.ajax({ 类型:" ， url:" ， 数据:" ， contentType:" ， dataType:" ， 成功:功能 succ(msg){ alert(' 被称为Ajax方法')； }， 失败:功能(响应){ 警报(响应)； } }); var that =

.ajax({ type: "POST", url: "Home.aspx/MethodSample", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function succ(msg) { alert('Called Ajax Method'); }, failure: function (response) { alert(response); } }); var that =

( this )，粘性=(that .hasClass(" )|| that.hasClass( 粘性内容"))? that.parents(' div.sticky'): obj = { id:sticky.attr(" )， 顶部:sticky.css(" )， 左:sticky.css(" )， 文字:write = sticky.children(" ).html().search( 文档 .getElementById(" ) .value)< = 0 吗? sticky.children(" ).html()+ " lblusername").value:sticky.children (" ).html() } localStorage.setItem(" + obj.id， JSON .stringify(obj)); sticky.find(" ).text( 已保存")； // alert('结束保存Stickey Sticky-'+ obj.id +''+ JSON.stringify(obj) ); }

(this), sticky = (that.hasClass("sticky-status") || that.hasClass("sticky-content")) ? that.parents('div.sticky') : that, obj = { id: sticky.attr("id"), top: sticky.css("top"), left: sticky.css("left"), text: write = sticky.children(".sticky-content").html().search(document.getElementById("lblusername").value) <= 0 ? sticky.children(".sticky-content").html() + document.getElementById("lblusername").value : sticky.children(".sticky-content").html() } localStorage.setItem("sticky-" + obj.id, JSON.stringify(obj)); sticky.find(".sticky-status").text("saved"); // alert('end to save stickey sticky-' + obj.id + ' ' + JSON.stringify(obj)); }

您需要在web.config中添加此代码，以启用从javascript调用WebMethods

You need to add this code in web.config to enable calling WebMethods from javascript

<system.web>
  <httpmodules>
    <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </httpmodules>
</system.web>

我错过了ScriptHandler的确切版本

对于VS2008.您需要使用此

Edited:

I missed the exact version for the ScriptHandler

For VS 2008. You need to use this

<httpModules>
       <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
     </httpModules>
