1 comment so far

A little snippet of code to pull in an html file and place the html content to a text field.

package
{
	import flash.display.Sprite;
	import flash.text.*;
	import flash.net.*;
	import flash.events.*;

	public class loadHTML extends Sprite
	{
		private var txtField:TextField;
		private var HTMLData:String;
		private var myHTMLFile:URLLoader;

		public function loadHTML()
		{
			myHTMLFile = new URLLoader();
			myHTMLFile.addEventListener(Event.COMPLETE, onLoadHTML, false, 0, true);
			myHTMLFile.addEventListener(IOErrorEvent.IO_ERROR, ioError, false, 0, true);
			myHTMLFile.load(new URLRequest("/path/to/html/file"));
		}

		private function onLoadHTML(e:Event):void
		{
			HTMLData = e.target.data;
			initTextField();
		}

		private function initTextField():void
		{
			txtField = new TextField();
			txtField.x = txtField.y = 20;
			txtField.width = stage.stageWidth;
			txtField.multiline = true;
			txtField.wordWrap = true;
			txtField.autoSize = TextFieldAutoSize.LEFT;
			txtField.selectable = false;
			txtField.htmlText = HTMLData;

			addChild(txtField);

			myHTMLFile.removeEventListener(Event.COMPLETE, onLoadHTML);
			myHTMLFile.removeEventListener(IOErrorEvent.IO_ERROR, ioError);
		}

		private function ioError(e:IOErrorEvent):void
		{
			trace ("Error: File " + e.text + " could not be loaded");
		}
	}
}
