Jmeter: Javascript variable not returning any value

I am using one Javascript function to generate a random Number.

Used a User Parameter(Preprocessor) under the request

Added a Variable: farmeid

Function: ${__javaScript('bam-'+parseInt((Math.random()*1000000),10))}

When I am using the varialble ${frameid}, it is returning no Value.

The problem is that there is a comma in your expression here: ),10 which acts as a delimiter for function parameters. If you can remove this ,10 bit so your expression could look like:

${__javaScript('bam-'+parseInt(Math.random()*1000000),)}

This would be successfully evaluated by __javaScript function.

If this 10 bit is a must you can use BSF PreProcessor with the following code:

vars.put("frameid",'bam-'+parseInt((Math.random()*1000000),10));

And the easiest way is using __Random function like 

bam-${__Random(111111,999999,)}

directly where it's required.

Hope this helps.

It's better to use Jmeter's Random Variable generator. http://jmeter.apache.org/usermanual/component_reference.html#Random_Variable
