Error message: Can't have 'break' outside of loop

Hi all
I get this message: Can’t have ‘break’ outside of loop with this code to validate that the fields have been entered.
How do I get rid of this message? Thank you

<script type="text/javascript">
  function validate_affil(){
  	var v =  true;
  			if( $.trim($(this).val()) == '' ){
  				alert('The fields marked (*) are required')
  				v = false;
  	return v;

<div class="SignupForm" class="width:100%;">
<form onsubmit='return validate_affil();' action="signup.php" method="post" style="border:0px solid;color:black;" id="icpsignup8855">

<fieldset style="border:0px;">
<label>Email*<input type="text" name="username" size="10" class='validate_affil' ></label>
<label>Name*<input type="text" name="firstname" size="10"  class='validate_affil' ></label>
<label>Surname*<input type="text" name="lastname" size="10"  class='validate_affil' ></label>

instead of break use return false.

To explain further, the jQuery each() command allows you to return false to break the loop, whereas anything else that’s returned results in the equivalent of continue.

From jQuery.each()

We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

Thanks Paul and wisher learnt a new thing today! Works great
