Is there a way to access a javascript variable using a string that contains the name of the variable?

Question

This way I could have a function that says whatever_way_you_do_this = something. Is this possible? Basically I could tell a function which variable I want to set by giving it a string that holds the name of the variable.

Thanks

Answer 1

If it is a global variable named myVar, you can use:

window["myVar"]

Answer 2

You can use

eval(variableString);

Proceed with caution as many don't recommend using eval()
