如何在asp.net页面中使用jquery和Ajax调用c#函数? [英] How to call a c# function using jquery and Ajax in asp.net page...?

问题描述

我想调用在页面后面的代码中声明的方法，实际上该方法用于重新生成ASP页面中datagrid的数据，我使用c#作为我在语言后面的代码.
这是方法....

I wanted to call a method declared in my code behind page, actually that method is used for refracing the data of datagrid in asp page, i used a c# as my code behind language.
this is the method....

public void search()
{
    int id = Convert.ToInt32(txtSearch.Value.ToString());
    ds.Clear();
    ds = (DataSet)ser.getDataID("SP_SELECT_DATA_FROM_INFO", id);
    if (ds.Tables[0].Rows.Count > 0)
    {
        grdMyGrid.DataSource = ds;
        grdMyGrid.DataBind();
    }
    else
    {
        Response.Write("No Record Found");
    }
}

现在我想使用带有Ajax的jQuery或javascript调用该方法...

我会尝试的，但是它不起作用

now i want to call that method using a jQuery or javascript with Ajax...

i will try this but it is not working

<script type="text/javascript">
        $(document).ready(function () {
            $("#ser").click(function () {
                if (confirm("Are you sure")) {
                    $.ajax({
                        type: "POST",
                        url: "GridDemo.aspx/search",
                        contentType: "application/json; charset=utf-8",
                        data: "{}",
                        dataType: "json",
                        success: function (msg) {
                            if (msg.d) {
                                alert("Sucess");
                            }
                        },
                        error: function () {
                            alert("Error try again");
                        }
                    });
                }
            });
        });        
        }
    </script>

推荐答案

(文档).ready(

(document).ready(function () {

( # ser").click(如果(确认(" )){

("#ser").click(function () { if (confirm("Are you sure")) {

.ajax({ 类型:" ， url:" ， contentType:" ， 数据:" ， dataType:" ， 成功:功能(msg){ 如果(msg.d){ alert(" )； } }， 错误:功能(){ alert(" )； } }); } }); }); } </script>

.ajax({ type: "POST", url: "GridDemo.aspx/search", contentType: "application/json; charset=utf-8", data: "{}", dataType: "json", success: function (msg) { if (msg.d) { alert("Sucess"); } }, error: function () { alert("Error try again"); } }); } }); }); } </script>
