Foreach logic controller cannot understand two or more input variable prefixes

Open asfimport opened this issue 4 years ago • 2 comments

YU (Bug 65129): When I use two extractors to extract 'title' and 'id', and set the "Match NO" value to -1, I get two array objects title and id at this time, and I want to use the forEach controller to process them in a loop These two arrays; When the title_1 element is processed, the id_1 element can also be processed, and when title_2 is processed, the id_2 element can also be located, but the forEach controller can only recognize one input variable; Because title and id appear in pairs, I need to process title according to title, but forEach cannot pass more than one input variable.

Created attachment bug.jmx: I visit https://www.catalog.update.microsoft.com/home.aspx , query all the information of kb4474419, and decide whether to process ID according to the title

@rollno748 (migrated from Bugzilla): Hello,

I guess, that is not necessary and would not be an ideal way to proceed with the scripting.

If your intention is to map the variable's ordinal - Then you can achieve it using pre-processor

I have attached a workaround - Have a look and revert
