Why did you put single quotes around i? My guess is you copied code from somewhere. So, just take a deep breath and look at the code.

You are storing 100 in price11 and 11 in i. So, add them together, price + i.

no did not copied the code. i need to have displayprice with value of price11(dynamically). currently getting error. because price becomes a variable which is not defined.

So, what exactly is your question then?

i have a price variables, price1=10, price2=20 and i=1. how do i assign price values to another variable.
var diplayprice;
displayprice = price+'i'; i is 1, so diplayprice should hold value of price1 which is 10

You can use eval.

displayprice = eval("price" + i);

JavaScript

var price=100;
       var i=11;
       var displayprice;
       displayprice = price + 'i'; // this will result '100i', since the 'i' is considered as a string.
       displayprice = price + i; // this results 111, since both are of int type

In your case, you shall use eval[^], or Angular Js Expression[^] to get the value as int
