Hi,

Is there any way in ActionScript to compare strings?

Normally in Java there is a .equals() method.

What about in AS?

i want to check if let's say, if x is equal to "PlayBook".

You could compare string lengths and then check that  the index of the first string in the second one is zero, using the indexOf() String method.  Also, you can pre-trim the strings with the mx.utils.StringUtil.trim() static class method.

BTW, I'm also new to AS3 and from your question I assumed you'd looked for an "==" operator & not found one.  However now that I look closer, since I'll need to do string comparisons as well, according to p. 133 of this:

http://livedocs.adobe.com/flex/3/progAS_flex3.pdf

"You can use the following operators to compare strings: <, <=, !=, ==, =>, and >."

PDF is 500+ pages of AS3 documentation straight from the horse's mouth.

String.search();
String.match();
String.indexOf();
String.lastIndexOf();

Any of the above could work, depending on your use case.

trace("Playbook" == "playbook");  //false
trace("Playbook" != "playbook");  //true
trace("This is stupid easy" != "This is stupid easy"); //false
trace("This is stupid easy" == "This is stupid easy"); //true

if you're trying to determine the OS at runtime, something like the following should work for you:

//Resoslve Operating System

private function resolveOperatingSystem():String
     {
     if         (Capabilities.os.toLowerCase().indexOf("win") > -1) return "Windows";	
     else if	(Capabilities.os.toLowerCase().indexOf("mac") > -1) return "Mac";
     else if	(Capabilities.os.toLowerCase().indexOf("qnx") > -1) return "PlayBook";
     else if	(Capabilities.manufacturer.toLowerCase().indexOf("and") > -1) return "Android";
     else if	(Capabilities.os.toLowerCase().indexOf("iph") > -1) return "iPhone";
     }

Unlike Java ActionScript actually lets you compare strings the exact same way you compare everything else. I for one, do not miss the clunky .equals() method one bit...
