how to reference object as string name

Question

I need to reference my object as a string but I am having issues.

ideally I would like this to work ['mystring'].myproperty; but obviously this wont work.

Is there another way besides the options below?

// auto generated ecample/////////////

var mystring = {
myproperty :'test'

}
/////////////////////////////////////

var optionA =mystring.myproperty; // works


var optionB = window['mystring'].myproperty; //gives issues


var optionC = eval('mystring').myproperty; //gives issues


var optionD = ['mystring'].myproperty; // wont work

optionC no use; overkill. optionD you're creating an array with one string inside, and the array doesn't have a myproperty method. So use A or B, those are correct. — elclanrs

I've used B and I've had issues, also want to find a way to do this. OP wants to use e.g. var x = "mystring"; alert(x.myproperty); — Peter PitLock

If you don't create all global variables you entirely avoid this issue. var MY = { mystring: { myproperty: 'test' } }; MY['mystring'].myproperty — elclanrs

If your variables are defined on a global scope, the following works

window[ mystring.myproperty ].data

If you are in a function's scope, things get a lot harder. Easiest way then is to define your objects in a specific namespace on window and retrieve the objects similar to the above code.
