Why not just pass the req pattern within the function call:

 <input type="tel" onblur="callonkeyup(this,'AccountNumber', '^[0-9]+\$');" value="" id="AccountNumber"/>

Hi Reinder Wit, reqpattern is dynamic, it will be updating when user change the card types

I am not able to reproduce your issue with your code. I have tried with the below code snippet, Can you please check it at your hand?

<!DOCTYPE html>
<html>
<head> 
<title>Test</title>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
</head>
<body>
<input type="tel" reqpattern="^[0-9]+\$" 
  onblur="callonkeyup(this,'AccountNumber',this.getAttribute('reqpattern'));" 
  value="" id="AccountNumber"/>
<input type="tel" reqpattern="^[a-z]+\$" 
  onblur="callonkeyup(this,'AccountName',this.getAttribute('reqpattern'));" 
  value="" id="AccountName"/>

<script>
function callonkeyup(obj,txtType,rpattern)
{
    alert(obj);
    alert(txtType);
    alert(rpattern);
}

</script>
</body>
</html>

Let me know if any concern.
