Christophe had a blog about embedding html in an iFrame, but this didn't help me since iFrames point to static HTML pages.
Here's an example of the working example where in-memory HTML is written to a new browser window:
http://www.vandalaysolutions.com/flex/html/testHTML.html
If you have a AS3 String like so:
var htmlStr : String = " this is my <b>bolded</b> and <i>italic</i> String";
Then by assigning it to the "htmlText" attribute of a mx:Text or mx:RichTextEditor
However, most HTML has far more crap in it, so you're really left with 2 options...parsing the HTML to get rid of all the crap (using RegEx) or pass the HTML off to the browser.
Using RegEx to parse everything was not a good solution for me b/c there are endless possibilites of how the HTML could appear. However, passing the HTML to the browser at first was causing problems.
The HTML that I received from the server had lots of empty lines....which the Javascript method was failing on.
var html : String = "<html>
<title>Website Title</title>
<body>
this is bold
</body>
</html>";
If you pass this to the javascript method via the ExternalInterface, you'll get the following javascript error:
Error: unterminated string literal
Source Code:
try { __flash__toXML(changeDocumentTitle("<html>
As you can see, the javascript can't handle the line break. So if you create a Regular Expression to replace all the line breaks and form feeds with an empty space, it essentially makes the HTML String one long String. Thus it can write the String to the new browser window:
//Flex method: htmlXML is of type: htmlXML : XML
var pattern:RegExp = /\n|\r|\f/gi
var htmlstr : String = htmlXML.toXMLString().replace(pattern, "");
var m:String = ExternalInterface.call("popNewWindow",htmlstr);
trace(m);//m is what the js method returns and Flex receives
//Method we need to add to the wrapper HTML page.
<script> language="JavaScript">
function popNewWindow(a) {
var generator=window.open('','name','height=550,width=700,resizable=yes,scrollbars=yes,status=yes,menubar=yes,toolbar=yes');
generator.document.write(a);
generator.document.close();
return "successful"; //passed back to Flex
}
</script>
