使用以下链接下载jQuery:

在你的ASPX页面中包含jQuery。



JS代码:

Include jQuery in your ASPX Page.

JS Code :
-----------
function clientSideFunction(myVal) {
    try {


.ajax({
type: post,cache: false async : false ,url: / yourPage.aspx / serverSideFunction,data: {'myObject':' + myVal + ,dataType: json,contentType: application / json; charset = udf-8

如果(rd!= null && rd!= ' '){
alert(rd);
}
}
});
} catch (错误){}
}
.ajax({ type: "post", cache: false, async: false, url: "/yourPage.aspx/serverSideFunction", data: "{'myObject':'"+myVal+"'", dataType: "json", contentType: "application/json; charset=udf-8", success: function (r) { if (r.d != null && r.d != '') { alert(r.d); } } }); } catch (err) { } }

Write WebMethod in your code behind page:

//Add below namespace in you page
using System.Web.Services;

[WebMethod]
public string serverSideFunction(string myObject)
{
     string result = null;
     // Write down your code here            
     return result;
}
