Why bind.('paste' with "if" must be done twice to be active

Question

I use a script to detect url in text when someone paste a text with URL.

So I use this script:

$("#post").bind('paste', function(){

   var $ptext = $('textarea#post').val();
   var regexText = /^http:\/\/www$/;
   if(regexText.test($ptext))
   {
    alert('URL DETECTED');
   }
});

But when I reload the page and I paste the text for the first time the script does nothing and I'm forced to repaste the text again, and then the script works.

How do I solve this problem?

Use the contextual `$(this)` rather than forcing to jQuery to look up the same selector again (`$('textarea#post')`) — Mitya, Jul 29 '12 at 15:27
ok.. have you tried to debug it? is `$ptext` ok? how do you know that `if` fails? what do you do inside? do you log to the console? — Karoly Horvath, Jul 29 '12 at 15:29
please do the whole debugging. what is send $.get? a simple console.log will do it.. — Karoly Horvath, Jul 29 '12 at 15:34
I don't know why, but for some reason `.bind()` needs a `setTimeout(function(){ //now do the textarea val() call;}, 100);` in order to access the updated paste event...but if you use `.on()` instead, it will work without the setTimeout call.. — Ohgodwhy, Jul 29 '12 at 15:36

what if he doesn't use paste? I'm not sure binding to paste is the right way. — Karoly Horvath, Jul 29 '12 at 16:08
