最好改用AJAX.它简单易实现.虽然
您可以使用javascript中的__dopostback发起回发..

Its better to use AJAX instead.Its simple and easy to implement. Although
you can initiate a postback using __dopostback from javascript..

现在在ASP.NET中执行此操作的标准"方法是使用AJAX.可以使用MS AJAX完成此操作，但我更喜欢使用jQuery的Ajax调用.

您要做的是在ASP.NET项目中创建一个ScriptService ，将服务器端代码添加为WebMethod，然后从您的JavaScript中调用它.如果您不想添加ScriptService，则可以将WebMethod 添加到Page.这是来自jQuery的典型ajax调用:

The "standard" way to do this in ASP.NET now, is to use AJAX. It''s possible to use MS AJAX to accomplish this, but I prefer to use jQuery''s Ajax calls.

What you do is create a ScriptService in your ASP.NET project, add the serverside code as a WebMethod, and then call it from your javascript. If you don''t want to add a ScriptService, you can add the WebMethod to a Page. Here''s a typical ajax call from jQuery:

.ajax({ type: "POST", url: "MyScriptService.asmx/GetDate", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { alert(msg.d); } });

.ajax({ type: "POST", url: "MyScriptService.asmx/GetDate", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { alert(msg.d); } });
