Question

I have a asp:Button that has an Onclientclick Event do some operation.

I want to trigger this OnclientClick manually using JavaScript or Jquery.

Answer 1

This being webforms, you’ll want to do something like this:

$("#<%= ASPButtonID.ClientID %>").click();

where ASPButtonID is the name of your button.

In response to your comment:
Add a click handler like so:

$($("#<%= ASPButtonID.ClientID %>").click(function(){ 
   // call your JS function from here 
}););

and then make the call above
