OK, first post. Lately I've been dabbling with Actionscript so here are two useful functions and I will update the post with more.
First one is an as3 utf8 encode function. This was found at Destroy Today
public static function encodeUTF8 (text:String):String {
var a:uint, n:uint, A:uint;
var utf:String;
utf = "";
A = text.length;
for (a = 0; a < A; a++) {
n = text.charCodeAt (a);
if (n < 128) {
utf += String.fromCharCode (n);
} else if ((n > 127) && (n < 2048)) {
utf += String.fromCharCode ((n >> 6) | 192);
utf += String.fromCharCode ((n & 63) | 128);
} else {
utf += String.fromCharCode ((n >> 12) | 224);
utf += String.fromCharCode (((n >> 6) & 63) | 128);
utf += String.fromCharCode ((n & 63) | 128);
}
}
return utf;
}
Second is an Actionscript implementation of PHP’s html_strip_tags from Flexer
public static function stripHtmlTags(html:String, tags:String = ""):String
{
var tagsToBeKept:Array = new Array();
if (tags.length > 0)
tagsToBeKept = tags.split(new RegExp("\\s*,\\s*"));
var tagsToKeep:Array = new Array();
for (var i:int = 0; i < tagsToBeKept.length; i++)
{
if (tagsToBeKept[i] != null && tagsToBeKept[i] != "")
tagsToKeep.push(tagsToBeKept[i]);
}
var toBeRemoved:Array = new Array();
var tagRegExp:RegExp = new RegExp("<([^>\\s]+)(\\s[^>]+)*>", "g");
var foundedStrings:Array = html.match(tagRegExp);
for (i = 0; i < foundedStrings.length; i++)
{
var tagFlag:Boolean = false;
if (tagsToKeep != null)
{
for (var j:int = 0; j < tagsToKeep.length; j++)
{
var tmpRegExp:RegExp = new RegExp("<\/?" + tagsToKeep[j] + "( [^<>]*)*>", "i");
var tmpStr:String = foundedStrings[i] as String;
if (tmpStr.search(tmpRegExp) != -1)
tagFlag = true;
}
}
if (!tagFlag)
toBeRemoved.push(foundedStrings[i]);
}
for (i = 0; i < toBeRemoved.length; i++)
{
var tmpRE:RegExp = new RegExp("([\+\*\$\/])","g");
var tmpRemRE:RegExp = new RegExp((toBeRemoved[i] as String).replace(tmpRE, "\\$1"),"g");
html = html.replace(tmpRemRE, "");
}
return html;
}
An AS3 regular expression to check for email validity:
public static function validateEmail(email:String):Boolean {
var emailExpression:RegExp = /^[a-z][\w.-]+@\w[\w.-]+\.[\w.-]*[a-z][a-z]$/i;
return emailExpression.test(email);
}
Great piece of code! Thanks!
