How to fire a button click event from JavaScript in ASP.NET

How do I fire a server side button click event from JavaScript?

I tried like this:

document.getElementById("<%= ButtonID.ClientID %>").click();

But no use. How can I do it?

You can just place this line in a JavaScript function:

__doPostBack('btnSubmit','OnClick');

Or do something like this:

$('#btnSubmit').trigger('click');

var clickButton = document.getElementById("<%= btnClearSession.ClientID %>");
clickButton.click();

That solution works for me, but remember it wont work if your asp button has

Visible="False"

To hide button that should be triggered with that script you should hide it with <div hidden></div>

I used the below JavaScript code and it works...

var clickButton = document.getElementById("<%= btnClearSession.ClientID %>");
clickButton.click();

None of the solutions posted here would work for me, this was my eventual solution to the problem.

// In Server Side code
protected void Page_Load(object sender, EventArgs e)
{
    Page.GetPostBackEventReference(hiddenButton);
}

// Javascript
function SetSaved() {
    __doPostBack("<%= hiddenButton.UniqueID %>", "OnClick");
}

// ASP
 <asp:Button ID="hiddenButton" runat="server" OnClick="btnSaveGroup_Click" Visible="false"/>

I lived this problem in two days and suddenly I realized it that I am using this click method(for asp button) in a submit button(in html submit button) javascript method...

I mean ->

I have an html submit button and an asp button like these:

<input type="submit" value="Siparişi Gönder" onclick="SendEmail()" />
<asp:Button ID="sendEmailButton" runat="server" Text="Gönder" OnClick="SendToEmail" Visible="True"></asp:Button>

SendToEmail() is a server side method in Default.aspx SendEmail() is a javascript method like this:

<script type="text/javascript" lang="javascript">
   function SendEmail() {
            document.getElementById('<%= sendEmailButton.UniqueID %>').click();
            alert("Your message is sending...");
        }
</script>

And this "document.getElementById('<%= sendEmailButton.UniqueID %>').click();" method did not work in just Crome. It was working in IE and Firefox.

Then I tried and tried a lot of ways for executing "SendToEmail()" method in Crome.

Then suddenly I changed html submit button --> just html button like this and now it is working:

<input type="button" value="Siparişi Gönder" onclick="SendEmail()" />

Have a nice days...
