How can I refer to a variable using a string containing its name?
Solution 1:
You can use an eval to do it, though I try to avoid that sort of thing at all costs.
alert(eval(someString));
A better way, if you find yourself needing to do this, is to use a hash table.
var stuff = { myText: 'hello world!' };
var someString = 'myText';
alert( stuff[someString] );
Solution 2:
If that variable is on the global scope, you can use the bracket notation on the global object:
var myText = 'hello world!';
var someString = 'myText';
alert(window[someString]);
