Jquery - if page loaded

Question

Is there any trick how to start a function in javascript, which starts when the page is completely loaded?

Answer 1

If you mean when the HTML document has loaded, use the ready event:

$(document).ready(function(){
  ...
});

Or the shorthand:

$(function(){
  ...
});

If you mean when the page including all style sheets, scripts, images and whatnot has completed loading, use the load event:

$(window).load(function(){
  ...
});
