How to reference variable within another variable/params in javascript? [duplicate]

Question

I would like to refactor my javascript code with an function.

ingos - is a name of the company and I have 5th of similar code parts.

    $('#ingosRegularPrice').removeClass("inactive");
    $('#ingosActivePrice').removeClass("inactive");
    $('#ingosRegularPrice .btn span').text(ingosPrice);
    $('#ingosActivePrice .btn span').text(ingosPrice * params.ingos.programB);

with something like

  function setPriceActive(company){
    $('#'+ company + 'RegularPrice').removeClass("inactive");
    $('#'+ company + 'ActivePrice').removeClass("inactive");
    $('#'+ company + 'RegularPrice .btn span').text(companyPrice);
    $('#'+ company + 'ActivePrice .btn span').text(ingosPrice * params.company.programB);
  }

But I get an reference error that 'company' variable doesn't exist. How I can use function params as an text reference and part of other variable name?

Thanks

You can use variable inside jQuery selector. Please verify company you are passing correctly or not — subrahmanya bhat

Really? No duplicate worth posting? ;)

All questions are duplicates in some way. However, it's clear with dot notations. Thanks. I just didn't know how the formulate the question on search. What about variable names? text(ingosPrice) . How do I use (companyPrice) instead?

Sergey, this[company + "Price"] should work. this would be the context depending where you declared the variable ignosPrice.
