Call a JavaScript function name using a string?

Question

How can I hook up an event to a function name I have defined as a string?

I\'m using Prototype.js, although this is not Prototype-speficic.

$(inputId

If you need to call a string function with arguments, do this:

window[stringFunctionName].apply( window, arrayOfArguments )

You can use scope in place of window if preferred
