How do I declare and use dynamic variables in JavaScript?

Question

Suppose I need to declare a JavaScript variable based on a counter, how do I do so?

var \"text\"+pageNumber;

Answer 1

Assuming that the variable is in the global scope, you could do something like this:

var x = 1;
var x1 = "test"
console.log(window["x" + x]); //prints "test"

However, a better question might be why you want such behaviour.
