Re: [flexcoders] [Flex/Javascript] Javascript function not found when called from Flex

Mon, 10 Oct 2005 07:16:25 -0700

Hi Manish,
 
I guess the below works out for U!!!
Try it out!!
 
 
Code for Mxml:
 
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml">
 <mx:Script>
 <![CDATA[
  import mx.controls.Alert
  
  function callJS(){
   Alert.show("Clicked on Btn")
   var someText = "SomeText from FLex";
   getURL("_javascript_:jsFun('"+someText+"')");
   
  }
 ]]>
 </mx:Script>
 <mx:Canvas> 
  <mx:Button label="click" click="callJS()"/>
 </mx:Canvas>
</mx:Application>
 
Code for embedding mxml in HTML and call JS
 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Flex n HTML</title>
<script language="_javascript_">
 function jsFun(txt){
  alert(txt)
 }
</script>
</head>
 <body>
  <object classid="" codebase="" href="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0"> http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="200" height="200">
    <param name="movie" value="imageClick.mxml.swf">
    <param name="quality" value="high">
    <embed src="" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer " type="application/x-shockwave-flash" width="200" height="200"></embed>
  </object>
 </body>
</html>
 
The first block gives you the structure of Mxml code, a button that calls an AS function which uses to getURL() to call Js function.
 
The sec block is just html page that has mxml embedded in it and js function (jsFun) that is being referred by AS.

I don't see anything obviously wrong.  What version of IE are you using?
