jquery trigger or click not working? -

i struggling why can't trigger or click work?

here js:

$(document).ready(function () {           function libertypop(){           var popup = jquery("#lightbox-30835684809970");         popup.click();         popup.trigger('click');         console.log("should work");     }      libertypop(); }); 

this should triggering click on anchor:

<a id="lightbox-30835684809970" style="cursor:pointer;color:blue;text-decoration:underline;">     liberty pop-up </a> 

in page, when click on link, pop appear, don't understand why jquery 'trigger' or 'click' not doing same?

if want trigger native click event of anchor tag, use js event:

 var popup = jquery("#lightbox-30835684809970")[0]; //<< [0] retruns dom node    popup.click(); 

but didn't have setted attribute href, nothing!

if want trigger click handler attached using jquery, first set one.

using code:

$(document).ready(function () {           function libertypop(){           var popup = jquery("#lightbox-30835684809970");         popup.on('click',function(){             console.log("works!");         }).click();     }      libertypop(); });
