onBlur coldfusion validate

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 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.



<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.
