Javascript button click event - Firefox

In some instances we may need to perform a button click event through JavaScript.

This would be look like this:

<script language="javascript">
   function doSomeThing();
   {
       //do something
       var btn = document.getElementByID('btnHidden');
       btn.click();
   }
</script>

This will works fine in IE, but wont work in Firefox.

To get it work in Firefox add UseSubmitBehavior="false" property to button.

This will make the button postback with the ASP.NET postback model.

ex:-

<div style="display:none;">
   <asp:Button id="btnHidden" runat="server"
               OnClick="btnHidden_Click"
               UseSubmitBehavior="false"
               />
</div>

How it works: Compare html generated by .Net framework with UseSubmitBehavior and without this.

With UseSubmitBehaviour="false" it will render onclick event for button & without this it wont render onclick event.
