Can I store JavaScript functions in arrays?

Question

How can I store functions in an array with named properties, so I can call like

FunctionArray["DoThis"]

or even

Function         


        

Answer 1

You want an object literal, not an array.

x = { 'dothis': function() { alert('hi'); } };

Object

x['dothis']()

You can also dynamically invoke

y = 'dothis';
x[y]()

Static/hard coded invocation:

x.dothis()

If you do want an array though:

x = [function(){alert('hi');}][0]()
