Randomly selecting object from a web page in TruClient- HPE Loadrunner

Question

I am working Loadrunner 12.55, and Using TrueClient Protocol to design script for my application.

I have been blocked in an issue, where for each iteration the script should click on random object in the list . Not able to achieve this through normal Parameterization provided by TrueClient.(It doesn't allow me to parameterize Action itself).

Below is the step configuration i tried but didn't work:

Click on PerfTest3

Roles: "javascript_link, focusable, element"
Name: PerfTest3
ID Method: JavaScript
JavaScript =

var linkList = document.getElementsByTagName("a");
random(linkList);

Logic to randomly click objects on the page needs to be written in javascript? Please assist me to solve this issue. PFB screenshot for further understanding the problem.

Thanks in advance

As far as I see your solution to use JavaScript identification and to use the random method that is defined inside the JavaScript identification context is a good one. W hen trying it myself it worked with your code as well but maybe in your case, this is a more complicated DOM hierarchy and in that case, you might want to use the evalXPath method instead of the getElementsByTagName method and change the simple “//a” to something more custom for your application:

var linkList = evalXPath("//a");

random(linkList);

you can also try to use Descriptors and change the identification to this:
