推荐答案

尝试类似这样的事情

背后的代码

Try some thing like this

Code behind

public void logout()
{
}

客户页面

client page

<script type="text/javascript">
    window.onunload = unloadEvents;
    function unloadEvents()
    {
      <% logout(); %>
    }
</script>

从html按钮调用服务器端函数，您需要像这样调用.

您需要将该函数设为静态并使用webmethod属性对其进行标记.

然后在设计端编写javascript函数，当您使用jquery/javascript ajax请求从您端调用任何webservice函数时，将触发ajax请求以从代码中调用该函数.

您的javascript函数如下所示.

for calling server side function from html button you need to call like this.

you need to make that function static and mark that with webmethod attribute.

then write javascript function on your design side that will fire a ajax request to call that function from your code behind as you call any webservice function from your side using jquery/javascript ajax request.

Your javascript function look like this.

<script type="text/javascript">
function DeleteData() {

.ajax({ 类型:" ， 网址:" ， 数据:" ， contentType:" ， dataType:" ， 成功:功能(msg){ alert(" )； // 如果您的Codebehind方法返回某些内容，则将使用msg的.d属性访问该数据或结果 // 像这样... // alert(您的方法返回数据为..." + msg.d)； }， 错误:功能(msg){ alert(" ); } }); 返回 假； } </script>

.ajax({ type: "POST", url: "Default.aspx/DeleteData", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { alert("Your function called sucessfully"); //if your Codebehind method return something then that data or result will be accessed using .d attribute of msg //like this... //alert("Your method return data is ..." + msg.d); }, error: function (msg) { alert("There's some error in calling your function."); } }); return false; } </script>

和您的代码背后的功能是这样的...

and your code behind function like this...

[WebMethod]
public static void DeleteData()
{
       //your code
}
