I need call flash function from javascript. I use flash.external and addCallback to do this. all things work well but when I use FileReference in my flash, function did not open my browser ...
please see below describtion:
I call my function in javascript with this code:
<input type="button" value="Browse" onclick="sendToFlash('Hello World! from HTML');" />
you can see all my HTML as below:
<html>
<head>
<title>Upload test</title>
</head>
<script>
function hello (size) {
alert ("size hast: " + size);
}
function sendToFlash(val){
var flash = getFlashObject();
flash.new_browser(val);
}
var flash_ID = "Movie2";
var flash_Obj = null;
function getFlashObject(){
if (flash_Obj == null){
var flashObj;
if (navigator.appName.indexOf( "Microsoft" ) != -1){
flashObj = window[flash_ID];
}
else{
flashObj = window.document[flash_ID];
}
flash_Obj = flashObj;
}
return flash_Obj;
}
</script>
<body>
<center>
<embed width="560" height="410" type="application/x-shockwave-flash"
flashvars="sampleVars=loading vars from HTML"
salign="" allowscriptaccess="sameDomain" allowfullscreen="false" menu="true" name="Movie2"
bgcolor="#ffffff" devicefont="false" wmode="window" scale="showall" loop="true" play="true"
pluginspage="http://www.adobe.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"
quality="high" src="Movie2.swf">
</center>
<input type="button" value="Browse" onclick="sendToFlash('Hello World! from HTML');" />
</body>
</html>
when I click Browse in html page, javascript call sendToFlash function and SendToFlash function send my string (Hello World! from HTML) to flash.
in flash I get this string with below code:
resultsTxtField.text = "";
uploadButton.onPress = function () {
return browse_file("Hello World! from Flash");
}
import flash.external.*;
ExternalInterface.addCallback("new_browser", this, browse_file);
function browse_file (my_test_val) {
_root.resultsTxtField.text = "val: " + my_test_val;
import flash.net.FileReference;
var fileTypes:Array = new Array();
var imageTypes:Object = new Object();
imageTypes.description = "Images (*.jpg, *.jpeg, *.gif, *.png)";
imageTypes.extension = "*.jpg; *.jpeg; *.gif; *.png";
fileTypes.push(imageTypes);
var fileListener:Object = new Object();
var btnListener:Object = new Object();
var fileRef:FileReference = new FileReference();
fileRef.addListener(fileListener);
fileRef.browse(fileTypes);
fileListener.onCancel = function(file:FileReference):Void
{
_root.resultsTxtField.text += "File Upload Cancelled\n";
}
fileListener.onSelect = function(file:FileReference):Void
{
_root.resultsTxtField.text += "File Selected: " + file.name + " file size: "+ file.size + " file type: " + file.type;
getURL("javascript:hello("+file.size+");");
}
}
I have only one Scene and this code is on root of this Scene. and I have one movie clip named uploadButton and has only a rectangle that work as button in this sample.
when you click on rectangle browse_file("Hello World! from Flash"); called and a browser open that you can select a photo to upload.
when you click on browse in html same process must do but as you see variable send to function but browser to select a photo did not open any more.
I try several ways. for example I set new function to open only picture browser or set new Scene or use gotoAndPlay and more but there is another problem.
you can download my source from below link:

note that javascript onclick="sendToFlash('Hello World! from HTML');" don't work in direct opening. you must open it in localhost.
I'll be so so happy for any clue.
thanks so much
