lists in javascript

April 17, 2011 | 1:59 am

Hi,

I am not too experienced with JS. I am stuck on using only certain elements from a list. I am trying to take an object’s location (x y width height) and keep it’s current x and y while changing the width and height. I looked at the examples for lists and strings and couldn’t figure this out. Any suggestions on where to look?

Thanks,
Eric

different ways you could approach this. the easiest would probably be using arrays. for example:

var myBox = new Array(4);

Now you have a myBox with 4 slots for information. Now you can put information into the array by accessing each slot like this: myBox[0], myBox[1], myBox[2] and myBox[3] (arrays are always indexed from 0!!).
To output the entire array out an outlet you simply do: outlet(0, myBox), for individual elements outlet(0, myBox[2]).
Hope this is helpful.
