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

Question

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?

Answer 1

You can just place this line in a JavaScript function:

__doPostBack('btnSubmit','OnClick'); 

Or do something like this:

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

Answer 2

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>
