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

Property accessors can be used to access any object's properties or functions.

If the function is in the global scope, you can get it using the window object:

var myFunc = window[myFuncName];

This also works within the this scope:

var myFunc = this[myFuncName];
