Question

我想从aspx页面调用一个c＃函数我尝试过如下

 function  DeleteKartItems(callback) {

   $.ajax({
             type: "POST",
             url: 'About.aspx/updatingdatabase',// my function name in c#
             data: '{"username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',
             contentType: "application/json; charset=utf-8",
             dataType: "json",
             success: function (data) {
                              var x = data.d;// i am trying to store the return data into a local variable

             },
             error: function (e) {

             }
         });

     }

我的问题是当我将c＃函数写为静态时它的工作正常，但其他方面它不会工作，我想知道是否有任何方法从aspx页面调用非静态c＃函数提前致谢

Answer 1

不可能直接通过url从aspx页面运行函数。

尝试以下方法：

更改您的ajax请求，如下所示：

$.ajax({
     type: "POST",
     url: 'About.aspx',
     data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',
     contentType: "application/json; charset=utf-8",
     dataType: "json",
     success: function (data) {
                      var x = data.d;// i am trying to store the return data into a local variable

     },
     error: function (e) {

     }
 });

更新您网页中的Page_Load处理程序：

protected void Page_Load(object sender, EventArgs e)
{
    if (!String.IsNullOrEmpty(Request["method"]) && String.Compare(Request["method"], "updatingdatabase", true) == 0)
    {
        UpdatingDatabase(); //run the method
    }
}

Answer 2

试试这个

data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',

而不是

 url: 'About.aspx',
     data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',

并在pageload中调用函数
