Is there a way to use the result of a Coldfusion query in a JavaScript function?
<CFQUERY name ="getPin" datasource = "pins">
SELECT pin
FROM pinuser
where email="#getEmail#"
</cfquery>
I am attempting to assign the pin to a JavaScript variable named pincode. I have tried the following:
var <cfoutput>#ToScript(#pin#,"pincode")#;</cfoutput>
and then
alert(pincode)
however, this method does not seem to work. Any suggestions on how to achieve this?
Here's a straightforward and practical example:
<script>
<cfoutput>#toscript(getPin.pin, "JSVariableName")#</cfoutput>
</script>
Your result will look something similar to this:
<script>
var JSVariableName = 12345; //
</script>
Here is a solution that should be effective:
<script type="javascript" language="text/javascript>
<cfoutput>
var pincode = '#getPin.pin#';
alert(pincode);
</cfoutput>
</script>
To improve the code, consider adding a "top 1" in the SQL query or using maxrows=1 in the cfquery tag, especially if the email is not the primary key of the table or does not have a unique constraint.
