for every [a,b,c,d]

4 posts in this topic

this is a useful and somewhat popular method for iterations:

FOR $a IN [a,b,c,d] (similar to DOS batch command), or..

FOREACH $a [a,b,c,d] (similar to tcl)

they both do the same thing. changing variable $a for every element of the set.

i'm trying to do something similar and can't find the v3 equivalant.

is this available in v3 or do i have to hack my own function?

:ph34r:

You probably want to StringSplit the string into an array and then do a for.. next loop.

$Arr = StringSplit("a,b,c,d",",")
For $x = 1 to $arr[0]
     msgbox(0,'test',$arr[$x])
next

That's a little different from his intention though.

He's looking for something that would do this.

$Arr = StringSplit("Silly Rabbit", " ");
Foreach $Val in $Arr
    MsgBox(0, 'Array Value', $Val);
EndForeach

Which would return:

2

Silly

Rabbit

At least, that's how I see it. I use Foreach a lot in PHP, it's really handy.

But JdeB is right, it's easier to just go with a regular for loop. It would be different if AutoIt supported Associative arrays, then the For...In construct would be very handy. But otherwise your best bet is something like what JdeB posted.

:( that's similar to what i was thinking but it's a bit code-ugly since that stringsplit has to sit there everytime. functional though. :ph34r:
