I have a text field that is entered (18 characters max). and I want to make sure this value does not
already exist on a table. Instead of validating after a submit, I would like to validate after entry is made,...
so onBlur.

I am trying to figure out how to write the function to make cfquery. If exists, error that need to re-enter new
value. I have done 'static' data checks but not a cfquery.

I am on CF 9

Use  <CFDIV> tag  for AJAX call.

e.g.


<cfform name="form1">
YOUR INPUT FIELD:<cfinput name="stext1" type="text" >
</cfform>

<!--- CFDIV --->

<cfdiv bindonload="false"  bind="url:CheckInput.cfm?idt={stext1@blur}" ID="theDiv"
        style="background-color:##CCffFF; color:red; height:100"/>




For testing purpose use the following cfm file.

<!-- CheckInput.CFM --->

<cfdump var="#url#">

Okay, I had a typo. and it is responding with "no record", or dump. But if the record exists, I want the user to re-enter a another number. If the record does not exist, then allow the entry and go to next field.

1. Usage of cfdebug

    Add to your page which is holds cfdiv tag

       e.g. :   http://localhost/mypage.cfm?cfdebug


When ever any AJAX requests are posted, the debug window is updated.

2. You many not have to pass session variable. It is available across all requests/cfm pages.

Here is better checkinput.cfm

<!---<cfdump var="#url#">--->

<cfset reclist="1,3,5">
<cfset found=false>
<cfloop index="ix" from="1" to="#ListLen(reclist)#">
<cfif ListGetAt(reclist,ix) eq #url.stext1#>
<cfset found=true/>
<cfbreak/>
</cfif>
</cfloop>
<cfoutput>
<cfif #found#>
<script type="text/javascript">
document.form1.stext1.value='RECORD EXISTS, Enter Another Number';
</script>
<cfelse>
<h2>RECORD DOES NOT EXISTS</h2>
</cfif>
</cfoutput>


The main page is unchanged.



<cfform name="form1">
<br/>TEXT:<cfinput name="stext1" type="text" >
</cfform>
<cfdiv bindonload="false"   bind="url:CheckInput.cfm?stext1={stext1@blur}" ID="theDiv"
        style="background-color:##CCffFF; color:red; height:100"/>
