<p>You can solve your problem using two <code>HiddenField</code>.</p>

<ul>
<li>Set the two HiddenField using js/jquery(as you prefer)</li>
<li>Force the form submit in the js function(<code>form1.submit()</code>)</li>
<li>In the formLoad check if the HiddenFields are empty. If no run your method and then clear the HiddenFields</li>
</ul>

}|2785386|我没有使用HiddenFields，而是使用了一个隐藏按钮。这个模型工作得更好，因为我可以直接转到按钮的事件处理程序，而不必向Page_Load函数添加代码。|2785387|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

<p>Here's how I did it...</p>

<pre><code>&lt;script type="text/javascript"&gt;
function AddParticipant(companyid, employeenumber)
    {
        $("#AddParticipantPanel").dialog("close");
        var myargs = {CompanyId: companyid, EmployeeNumber: employeenumber};
        var myargs_json = JSON.stringify(myargs);
        __doPostBack('&lt;%= SelectParticipantBtn.UniqueID %&gt;', myargs_json);
    }
&lt;/script&gt;
&lt;asp:Button runat="server" ID="SelectParticipantBtn" ClientIDMode="Static" OnClick="SelectParticipantBtn_Click" style="display:none;" /&gt;
</code></pre>

<p>And on the server side...</p>

<pre><code>/* this is an inner class */
public class SelectParticipantEventArgs
{
    public string CompanyId {get; set;}
    public string EmployeeNumber {get; set;}
}
protected void SelectParticipantBtn_Click(object sender, EventArgs e)
{   
    string args = Request.Form["__EVENTARGUMENT"];
    var myargs = JsonConvert.DeserializeObject&lt;SelectParticipantEventArgs&gt;(args);
    string emp_no = myargs.EmployeeNumber;
    string company_id = myargs.CompanyId;
    //do stuff with my arguments
}
</code></pre>

<p>Instead of using HiddenFields, I used a hidden button. This model works better because I can go directly to the button's event handler instead of having to add code to the Page_Load function.</p>


blocks|key|3328634|text|您可以使用__doPostBack函数将其发送到服务器。只需确保向页面添加了一个服务器控件，以便插入该函数。下面是一个小示例，您可以根据您的需要进行定制：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3328635|aspx：|3328636|<%25@+Page+Language="C#"+AutoEventWireup="true"+CodeBehind="WebForm1.aspx.cs"+Inherits="Try1.WebForm1"+EnableEventValidation="false"%25>

<p>You can use the __doPostBack function to post to server. just make sure you add a server control to the page so the function is inserted. here is a small example that you can customize for your needs:</p>

<p>aspx:</p>

<pre><code>&lt;%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Try1.WebForm1" EnableEventValidation="false"%&gt;

&lt;!DOCTYPE html&gt;

&lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
&lt;head runat="server"&gt;
    &lt;title&gt;&lt;/title&gt;
    &lt;script src="Scripts/jquery-1.10.2.min.js"&gt;&lt;/script&gt;
    &lt;script type="text/javascript"&gt;
        $(document).ready(function () {
            $('#lblInvoke').hover(
                function () {
                    __doPostBack('&lt;%= LinkButton1.ClientID %&gt;', 'value1,value2');
                     }
                );
             });
    &lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;form id="form1" runat="server"&gt;
    &lt;div&gt;
        &lt;label id="lblInvoke"&gt;Hover This!&lt;/label&gt;
        &lt;br /&gt;
        &lt;asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Style="display:none;"&gt;LinkButton&lt;/asp:LinkButton&gt;
        &lt;asp:Label ID="Label1" runat="server" Text=""&gt;&lt;/asp:Label&gt;
    &lt;/div&gt;

    &lt;/form&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>code behind:</p>

<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Try1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        protected void LinkButton1_Click(object sender, EventArgs e)
        {
            string passedArgument = Request.Params.Get("__EVENTARGUMENT");
            string[] paramsArray = passedArgument.Split(',');
            Label1.Text = string.Format("Returned from server. params: {0},{1}", paramsArray[0], paramsArray[1]);
        }
    }
}
</code></pre>

<p>Make sure you add the EnableEventValidation="false" attribute to page.</p>


<p>I have a function on my server side.</p>

<pre><code>protected void SelectParticipant(string CompanyId, string EmployeeNumber)
{
    //I do some stuff here.
}
</code></pre>

<p>I want to call this function from JavaScript on the client side. I've tried searching for it, but all the suggestions I found were for calling a Page Method via AJAX. I don't want that, I want to cause a postback.</p>

<pre><code>function MyJSFunction(companyid, employeenumber)
{
    //cause postback and pass the companyid and employee number
    //this is where I need help!
}
</code></pre>

<p>How can I cause a postback and run a server side function from my JavaScript?</p>


Call Code Behind Function from JavaScript (not AJAX!)
