Calling Javascript in Flex

Question

Hi
I have a mxml file that has a button control
<mx:Button id="toggle" label="Test" click="ToggleButton()"
/>
When I click on the button I want to call the javascript
function. So in the mxml script I have
public function ToggleButton(): void
var f:String = "JSToggleButton";
var m:String = "this works";
var check:String;
if(ExternalInterface.available)
ExternalInterface.call(f,m);
check = "true"
else
check="false";
trace(check);
]]>
Now I created a text file by rightclicking on the assets(The
folder i created) folder in project and then new-->File.
I have written my javascript in that file and named it
JavaScriptToggle.html
This file has the following code
<SCRIPT LANGUAGE="JavaScript">
function JSToggleButton(m)
alert(m);
</SCRIPT>
It does not seem to show the alert box but the trace shows
true for ExternalInterface.available.
Am I missing anything important?????
I am completely new to flex. So it might be simple to most of
them. Please bear with me.

If I have a project named Test does this mean that I have to
include my Javascript in the bin folder's Test.html file?
Yes, so somewhere in Test.html you will have to have that
javascript function. But remember that flex builder will recreate
the Test.html file everytime you rebuild and you will lose any
changes you make to that file directly. So make your alterations to
the html-template/index.template.html file and it will always
recreate your Test.html with that code included.
So just open up html-template/index.template.html and place
between the head tags
&lt;script language=&quot;javascript&quot;
type=&quot;text/javascript&quot;&gt;
function JSToggleButton(m)
alert(m);
&lt;/script&gt;
Then everything should hopefully be working
