Title: Onvalidate attribute of cfinput...
Dunno if you are familiar with FusionScript yet (www.fusionscript.com) - but its pretty easy with it -- here is an example :
 
<cf_fs_activeServer action="getAttributes">
<cfif activeServer.requestMode>
 <cfquery datasource="myDSN" name="qUsers">
  Select * from users where username = '#activeServer.username#'
 </cfquery>
 <cfif qUsers.recordCount>
  <cf_fs_activeServer action="return" name="usernameValid" value="no">
 <cfelse>
  <cf_fs_activeServer action="return" name="usernameValid" value="yes">
 </cfif>
 <cfabort> 
</cfif>
 
<html><head><title>Untitled</title></head>
 
<script>
 <cf_fusionscript action="libraries">
  form.*
 </cf_fusionscript>
</script>
 
<cf_fusionscript action="code">
 <cf_fs_function name="checkName">
  <cf_fs_activeServer action="call"
   page="thisPage.cfm"
   username="form.username">
  <cf_fs_if condition="usernameValid EQ 'no'">
   alert('please choose another user name');
  </cf_fs_if>
 </cf_fs_function>
</cf_fusionscript>
 
<body>
 
<form>
 <input type="Text" name="username" onchange="checkName();">
</form>
 
</body></html>

Hi All,
I need to check against a database to see if a username exists, how can I do that using onvalidate calling a javascript function?
