document.getElementById("id").value , change id by adding a variable to it

function totalCost(obj,a){    
  var price = document.getElementById("price").value;             
}

I want to create a new id adding variable a. If a =1, then the next id will be price1. How can I do it?

You can use Template Literals which allows embedded expressions:

function totalCost(obj,a){    
   var price = document.getElementById(`price${a}`).value;             
}

OR: Using String Concatenation (if browser is yet to support Template Literals)

function totalCost(obj,a){    
  var price = document.getElementById('price' + a).value;             
}
