کلاس RegExp

[arjmand200]

با سلام خدمت دوستان تا به حال کسی با این کلاس کار کرده البته من کارش رو میدونم برای استخراج اطلاعات خاص هستش ولی نحوه استخراجش رو نمیدونم مثلا من توی هلپ فلش این رو دیدم که میخواست این فرم ایمیل رو چک کنه لطفا اگه اطلاعاتی دارین ممنون میشم :

 var validEmail:String = "[email protected]";

private function validateEmail(str:String):Boolean {
            var pattern:RegExp = /(\w|[_.\-])+@((\w|-)+\.)+\w{2,4}+/;
            var result:Object = pattern.exec(str);
            if(result == null) {
                return false;
            }
            return true;
        }

این مثال رو کامپایل کن ؛ دسدت میاد ..

//Using Replace
var toungeTwister:String = "Peter Piper Picked a peck of pickled peppers";
//g is a global identifier so it doesn't stop only on the first match
var pickRegExp:RegExp = /pick|peck/g;
var replaced:String = toungeTwister.replace( pickRegExp, "Match");
//trace(replaced);

//Using Character Classes
var compassPoints:String = "Naughty Naotersn elephants squirt water";
var firstWordRegExp:RegExp = /N(a|o)/g;
//trace( compassPoints.replace( firstWordRegExp, "MATCH" ) );
													   
var favoriteFruit = "bananas";
var bananaRegExp:RegExp = /b(an)+a/;
//trace( bananaRegExp.test( favoriteFruit ) );

//Exec() method returns an Object containing the groups that were matched
var htmlText:String = "<strong>This text is important</strong> while this text is not as important <strong>ya</strong>";
var strongRegExp:RegExp = /<strong>(.*?)<\/strong>/g;
var matches:Object = strongRegExp.exec( htmlText);
for( var i:String in matches ) {
	//trace( i + ": " + matches[i] );
}

var email:String = "[email protected]";
var emailRegExp:RegExp = /^([a-zA-Z0-9_-]+)@([a-zA-Z0-9.-]+)\.([a-zA-Z]{2,4})$/i;
var catches:Object = emailRegExp.exec( email );
for( var j:String in catches ) {
	//trace( j + ": " + catches[j] );
}
//trace( "This e-mail's validity is: " + emailRegExp.test( email ) );

//Test the validity of an e-mail
var validEmailRegExp:RegExp = /([a-z0-9._-]+)@([a-z0-9.-]+)\.([a-z]{2,4})/;
trace( validEmailRegExp.test( "[email protected]" ) );


//Return a Boolean if there is a pattern match
var phoneNumberPattern:RegExp = /\d\d\d-\d\d\d-\d\d\d\d/; 
trace( phoneNumberPattern.test( "347-555-5555" )); //true 
trace( phoneNumberPattern.test("Call 800-123-4567 now!")); //true 
trace( phoneNumberPattern.test("Call now!")); //false 

//Return the index number of the occurence is there is a pattern match
var themTharHills:String = "hillshillshillsGOLDhills"; 
trace(themTharHills.search(/gold/i)); //15
