Inside of a function I'm getting a value from an input box, like this.
var $value = $('#inputid').val().toLowerCase();
So I want to have the returned variable $value be used to call another variable.
Above that code is a variable declaration.
var $somethingA = "1";
var $somethingB = "2";
If the user types in "somethingA" I want to get an alert that says "1". Is this possible?
Sorry if it is a silly question. Thanks!
That's possible, but you need to use an object as a map rather than multiple variables to hold your values.
var inputMap = {
somethingA: 1,
somethingB: 2
};
var input = $('#inputid').val().toLowerCase();
alert(inputMap[input]);
Note that if you were in the global scope (which would be a bad practice) you could just get the same effect by accesing variables using window[someDynamicProperty], since global variables are properties of the window object in a browser environment.
