Question

How do I reference a coldfusion query’s result in a javascript function?

<CFQUERY name ="getPin" datasource = "pins">
SELECT pin
FROM pinuser
where email="#getEmail#"
</cfquery>

I want to set the pin, as a JavaScript variable called pincode, I tried:

var <cfoutput>#ToScript(#pin#,"pincode")#;</cfoutput>

then

alert(pincode)

but it doesnt work, any ideas?

Answer 1

This should work:

<script type="javascript" language="text/javascript">
  <cfoutput>
    var pincode = '#getPin.pin#';
    alert(pincode);
  </cfoutput>
</script>

I would also include a “top 1” in the SQL or maxrows=1 in the cfquery tag, unless the email is the primary key of the table or otherwise has a unique constraint.
