Check file extention

SimonFinn · Nov 3, 2003

Hi Guys

I am using this code to check a file extension of a file path listed in a textbox. I have tried changing it to upper case which does not solve it.

Any ideas

Cheers Si

var iLen = String(frmDetails.txtFile.value).length;
if (String(frmDetails.txtFile.value).substring(iLen, iLen - 3) != "doc&quot

;
{
mesg = "Please verify your CV File and submit again." & String(frmDetails.txtFile.value).toUpperCase().substring(iLen, iLen - 3)
alert(mesg);
//Return Cursur
frmDetails.txtFile.focus();
//Stop submit
return (false);
}

Give this a try, let us know if you have any questions:

Code:

<html><head><script>
function ckext(frm) {
re = /doc/i;
ckstra = frm.tstval.value;
len = ckstra.length;
ckstrb = ckstra.substring(len-3,len);
 if(!ckstrb.match(re)) {
	mesg = 'Check File Name ' + ckstra;
	alert(mesg);
	return false;}
 else {  alert(&quot;\&quot;doc\&quot; ext found&quot;); return true; }
}
</script></head><body>
<form name=&quot;tst&quot;>
<input type=&quot;text&quot; name=&quot;tstval&quot; size=&quot;30&quot;>
<input type=&quot;button&quot; value=&quot;See Ext&quot; 
onClick=&quot;javascript:ckext(this.form);&quot;>
</form></body></html>[\code]
