Javascript function from array

Question

I have an array of strings which define class names. I would like to instantiate these classes using the string name. I have tried to use window but I haven't been able to do it.

The structure is

var objects = ['string1', 'string2'];

So the window would look like

window [
 objects [
 'string1',
 'string2' 
 ]
]

I have tried:

new window['objects'][0];

But that threw the string is not a func error.

Anyone know how to do this?

Thanks

• Ryan: window is a reserved word in javascript, why are you using it?
• Cjmarkham: To gain access to variables in the global scope
• the system: @ryan: window is definitely not a reserved word. Seems clear that OP is making reference to the global object,.

Answer 1

window.objects[0] is a string.
You want to get the property of window named by that string:

window[window.objects[0]]

• mellamokb: What does that have to do with creating objects by string name?
• Dave: he means you can do new window[window.objects[0]]( )
• Dave: ...although new window[objects[0]]( ) is shorter and just as good
• Cjmarkham: hm, i tried window[window.objects[0]] and also window[objects[0]] and they both came back as undefined
• Cjmarkham: window[window.objects[0]] would return window['string1'] which doesn't exist since it's in the objects array of window
