How to call a function in jQuery on window resize?

Question

I\'ve this code:

Answer 1

Please call the following method:

window.dispatchEvent(new Event('resize'));

Answer 2

You can't declare functions that way, use it like this.

<script>
 $(document).ready(larg);

 $(window).resize(larg);

 function larg(){
  var larghezza = $(document).width();
  $("p.width").text("The width for the " + larghezza + " is px.");
 }
</script>

EDIT: changed code a bit, thanks commenters
