Question

I got a strange problem with split function over the String. Please look at my example, How can I figure it out? Does It remove “\” from String by default?

public function code01():void {
    qrShow("C:/Documents and Settings/me/Desktop/a.gif;C:/Documents and Settings/me/Desktop/b.gif");
    qrShow("C:\Documents and Settings\me\Desktop\a.gif;C:\Documents and Settings\me\Desktop\b.gif");
}

public function qrShow(u:String):void{
    var imgArray:Array = u.split(";");
    for each(var addrs:String in imgArray) {
        trace (" --- " + addrs);
    }
}

The result is as follows:

— C:/Documents and Settings/me/Desktop/a.gif

— C:/Documents and Settings/me/Desktop/b.gif

— C:Documents and SettingsmeDesktopa.gif <— why no “\” ?

— C:Documents and SettingsmeDesktop.gif <— why no “\” and also “b” is changed !!!?

Is this a bug in Flash?

Answer 1

You need to escape a backslash (with another backslash).

For example try run this:

trace("\");

You’ll get an error.

You need to do this:

trace("\\"); // Output: \
