javascript - Uncaught ReferenceError not defined at HTMLAnchorElement.onclick -

i getting error in console:

uncaught referenceerror: check not defined @ htmlanchorelement.onclick

<a onclick="check();">payment</a> 

in js getting error due line, whats wrong in ?

<script type="text/javascript">   function check() {   {     var label<?php echo $k; ?> = "<?php echo $view; ?>";   }   } </script> 

i noticed have set of {} remove duplicate {}, code looks like:

<script type="text/javascript"> function check() {     var label<?php echo $k; ?> = "<?php echo $view; ?>"; } 

if problem still persistent, worth checking if have defined function before or after onclick call, because js might not have loaded (should not case, worth check).

hope helps!
