I need a really odd method of sorting something. I have an array of objects. I need to sort the array by a value in the object. I also need the ability to sort descending OR ascending. For example:

Code:

[
{
x:1,
y:2
},
{
x:2,
y:1
},
{
x:3,
y:3
}
]

Could get sorted ascending by y or descending by x.

I could no doubt make a function to do this myself, but no point in re-inventing the wheel. (In this case I'm not sure if the wheel exists

)

You can pass in a custom function to change the behaviour of the Array object's sort method. Check this out:
JavaScript Sorting
...the example looks perfect to what you're trying to do.

PS.: Long time no see :-)

Wow! Thanks spinal! That is exactly what I needed! I thought I would need to write a function to do it myself, which would have been a pain.

It would have been a bit of a pain. But thankfully most things of that sort (no pun intended) have already been done... :)
