How to exit from the execution of jquery code?

Question

I have multiple (10) if statemnets stacked in a function, and need something like this:

$len=$("#user").val().length; if($len == 0) { do something and then - stop, exit, break ... whatever)

So, if $len is 0 - do something and - dont check anything more. Just exit from the execution.

What to stop? I see no each of foreach of while... In JavaScript U can use break; or continue;. In jQuery.each() loop use 'return;' — algorhythm

You can use return statement but it will take the execution control at end of function and skip all the statements between. or use if-else block or use switch.

if($len == 0) { do something and then - stop, exit, break ... whatever return; )

Use if-else

if($len == 0) { do something and then - stop, exit, break ... whatever return; ) else if($len == 1) { do something and then - stop, exit, break ... whatever return; ) //repeate if else

Using switch

switch($len) { case 0: //execute code block 1 break; case 1: //execute code block 1 break; case 2: //execute code block 2 break; default: code to be executed if n is different from case 1 and 2 }

Just use this...

$len=$("#user").val().length; if($len == 0) { return false; }

I am returning false to make sure the event which invoked the function won't run anymore.

Thanks, ATOzTOA, I already accepted Adil's answer, but - that's it.
