String to object name 1

[batfg]

I have a script which grabs window.location, splits it and then puts part of it into a string. The script also defines a number of arrays.

I want to use the string to pull elements out of the associated array (assuming it exists). For example, if the string value is "X" I want to pull elements from the array that is called X, e.g. the elements X[0], X[1] etc.

The problem is that I can't simply write X[0] as X is a string. How can I relate the string value to the name of the array?

I think you can use eval to do what you want. I know at least that I use it to form whole JS statements from strings:

try {eval(document.jstest.ta1.value);}

Thank you. After playing around with eval I managed to do it using eval(splitstring[1].valueOf())[0] where splitstring[1] contained the name of the array I was trying to get to.

Thanks.
