javascript - calling a jQuery function named in a variable

Question

I have several jQuery function like function setOne(); setTwo(); setThree();

and a variable var number that values respectively "one", "two", "three".

How can I call function "setOne()" when number values "one", function "setTwo" when number values "two" and so on...?

Thank you so much in advance. Any help will be apreciated.

If you have your function in the global scope (on the window object) you can do:

// calls function setOne, setTwo, ... depending on number.
window["set" + number](); 

And using eval will allow you to run functions in local scope:

eval("set" + number + "()");

When is JavaScript's eval() not evil?
