I've a pop-up that can be called trough a link. The problem is that i need to call it onload, an I can't find a way to do this.
This is the code of the pop-up
   <a href="https://sloways.leadpages.co/leadbox/14169a873f72a2%3A14f192411746dc/5636318331666432/"
    target="_blank">Click Here to Subscribe</a>
    <script data-leadbox="14169a873f72a2:14f192411746dc"
    data-url="https://sloways.leadpages.co/leadbox/14169a873f72a2%3A14f192411746dc/5636318331666432/"
    data-config="%7B%7D" type="text/javascript"
    src="https://sloways.leadpages.co/leadbox-1483020619.js">
    </script> 
I've tried to trigger the "Click Here to Subcribe" in different ways, like the following, without success:
- Jquery how to trigger click event on href element
- jQuery(document).ready(function(){
 jQuery("#add_redirect").trigger('click'); });
- Window.location.href (this open the link but in another page, not as a pop-up)
UPDATE N.1
I've bypassed the problem loading the pop-up URL through the <object> tag.
I've put the <object> inside a Bootstrap modal so it still works like some kind of pop-up.
