Jmeter use variable to create variable and retrieve value

I know the title may be confusing but this is what I need to do:

I have a list of variables I am pulling from Jquery extractor.

 myVar_1 = 343
 myVar_2 = 98763
 myVar_3 = 5622 
etc

I generate a random number between 1 and myVar_matchNr.

Then I want to navigate to a URL that has an ID of one of the randomly selected variables. For instance, this would be the path I would like as an example:

//mydomain.com/api/resource/${myVar_${randomNumber}}

Which would translate to ( in the case my random number was 2):

 //mydomain.com/api/resource/98763

I have the random number, and I have the list of variables from the Jquery extractor, but I have been unsuccessful getting the value out of the combination.

I have tried the above URL directly. I have tried a beanshell script that looked something like:

 String myvarString = "myVar_" + get("myRandNumber");
 String myVar = get(myvarString);
 set("mySelectedVar", myVar);

That seemed to always come up an empty string.

Any suggestions on how to accomplish this?

One more option is Random Controller, you can create 3 different request and place it under Random Controller.i hope this will serve the purpose.

You can combine 2 variables using __V() function like

${__V(myVar_${randomNumber})}

In regards to Beanshell, you need to use vars object which stands for JMeterVariables class instance to manipulate the JMeter Variables like

String myvarString = "myVar_" + vars.get("myRandNumber");
String myVar = vars.get(myvarString);
vars.put("mySelectedVar", myVar);

See Here’s What to Do to Combine Multiple JMeter Variables article for more information on the topic.
