AS3 : RegExp exec method in loop problem
- by Boun
Hi everyone,
I need some help about RegExp in AS3.
I have a simple pattern :
patternYouTube = new RegExp ( "v(?:\/|=)([A-Z0-9_-]+)", "gi" );
This pattern is looking for the youTube id video.
For example :
var tmpUrl : String;
var result : Object;
var toto : Array = new Array();
toto = [http://www.youtube.com/v/J-vCxmjCm-8&autoplay=1, http://www.youtube.com/v/xFTRnE1WBmU&autoplay=1];
var i : uint;
for ( i = 0 ; i < toto.length ; i++)
{
tmpUrl = toto[i];
result = patternYouTube.exec ( tmpUrl );
if ( result.length != 0 && result != null )
{
trace(result);
}
}
When i == 0, it works perfectly.
Flash returns me : v/J-vCxmjCm-8,J-vCxmjCm-8
When i == 1, it fails.
Flash returns me : null
When I revert the two strings in my array such as :
toto = [ http://www.youtube.com/v/xFTRnE1WBmU&autoplay=1, http://www.youtube.com/v/J-vCxmjCm-8&autoplay=1 ];
When i == 0, it works perfectly :
Flash returns me : xFTRnE1WBmU
When i == 1, it fails :
Flash returns me : null
Do you have any idea about the problem in the loop ?
