Sort Problem 1

[coder1964]

Hi All

I am trying to sort an array using myarray.sort() and it doesnt really work.
I get a kind of sort but things are not right.
For example
[9,2,22,17,43]
after a sort will become
[17,2,22,43,9]

Is this a bug or am not not applying the sort method correctly.

T.I.A.

Hey,

I had this problem as well, and think it is because it is sorting it alphabetically as opposed to numerically. It thinks it is a string. I fixed it by storing all my single digit numbers in the array with a leading 0.

So, you would have [09,02,22,17,43] which should sort fine into [02,09,17,22,43]. From there when I was displaying the number I just put them through a function which stripped off the front 0 if it was there.

Hope this helps!

it is doing alphabetically however with a little tweak sort works just fine with numbers

use

arr.sort(function(a,b){return a>b})

gives [2,9,17,22,43]

Hey Bill,

Can you do that using sortOn() as well? It's what I was using and I'm having to add 0's and take them off when I put in and pull out of the array. I've got it all sorted now, but was wondering if you could do that with sort on?

 

[billwatson]

sorton requires a string and the only time i ever use it is when an array contains objects and i want to sort the array on a field

i dont see how it applies to numbers. to sort numbers just use the code i gave which does not need the addition of zeros to turn the numbers into a string

or am i missing something ?

Billwatson.

Many thanks. That works well.

Can you tell me why does the actionscript dictionary not explain that this is how you sort numbers?
