Currently making a Windows 8 RSS reader app for a specific site. Everything is working except for video [usually YouTube] since the website uses <object></object> to embed videos rather than <iframe>. the result is just a large blank object block where ever the video should be.
My first instinct was to find and replace the <object></object> tags with <iframe> and add the src attribute with the proper URL. I created a dummy app to test if this method would work, and the solution worked, if all you were changing was static HTML.
Dummy App Code:
<body>
<div style="text-align: center;">
<object width="853" height="480" id="test">
<param name="movie" value="http://www.youtube.com/v/2rDs7W3WRIk?version=3&hl=en_US"></param>
<param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param>
<embed src="http://www.youtube.com/v/2rDs7W3WRIk?version=3&hl=en_US" type="application/x-shockwave-flash" width="853" height="480" allowscriptaccess="always" allowfullscreen="true"></embed>
</object></div>
Wrote and called the below function, which does indeed work. Want to do something similar to the XML document:
function setHTML5video() {
var listOfSrcs = document.getElementsByTagName("embed");
for (var i = 0; i < listOfSrcs.length; i += 1) {
var videoSrc = document.getElementsByTagName("embed")[i].getAttribute("src");
var newSrc = videoSrc.replace("/v/", "/embed/");
//var newNode = '<iframe width="853" height="480" src="' + newSrc + '" frameborder="0" allowfullscreen></iframe>';
var iFrame = document.createElement("iframe");
iFrame.setAttribute("src", newSrc);
document.getElementsByTagName("object")[i].replaceNode(iFrame);
//WinJS.Utilities.setOuterHTMLUnsafe(test, newNode);
}
}
End of Dummy App Code.
However, due to lack of knowledge of the Windows 8 API and despite searching all day for the answer online, I cannot find how to do the same to an XML feed that is being downloaded from an external site. I am probably missing something fundamental.
function itemInvoked(z) {
var currentArticle = articlesList.getAt(z.detail.itemIndex);
WinJS.Utilities.setInnerHTMLUnsafe(articlecontent, currentArticle.content);
articlelist.style.display = "none";
articlecontent.style.display = "";
mainTitle.innerHTML = currentArticle.title;
WinJS.UI.Animation.enterPage(articlecontent);
}
When the user clicks on a thumbnail, the XML RSS feed for that corresponding article is pulled up and injected into the with the id = "articlecontent". I want to modify that feed prior to injecting it.
<section id="content">
<div id="articlelist" data-win-control="WinJS.UI.ListView"
data-win-options="{ itemDataSource: mmoNewsPosts.ItemList.dataSource, itemTemplate: MMOItemTemplate }"></div>
<!-- Article Content -->
<div id="articlecontent"></div>
<!-- Article Content -->
</section>
Edit, because there appears to be confusion, I already have the feed loaded in via WinJS.xhr:
function downloadMMOFeed(FeedUrl) {
WinJS.xhr({ url: FeedUrl, responseType: "xml" }).then(function (rss) {
pageTitle = rss.responseXML.querySelector("title").textContent;
mainTitle.innerHTML = pageTitle;
var items = rss.responseXML.querySelectorAll("item");
//more stuff...
for (var n = 0; n < items.length; n +=1) {
article.content = items[n].querySelector("description").textContent;
//more stuff...
Could you not just load the XML feed in by XHR and then parse the result before binding it to the page? For Example:
WinJS.xhr({
url: "http://www.w3schools.com/xml/note.xml", responseType: "xml"
})
.done(
function (request) {
var text = request.responseText;
//TODO : Parse the XML returned by the server which is in var text
});
In Windows 8 there is no cross domain restriction so something like this is entirely possible.

I am trying to get href link from google map as shown in screenshot. The link is inside iframe. It gives null/error value from this below code. Google map is embed using jquery.
I tried: `
var a_href = $(this).find('div .google-maps-link a').attr('href');

I want to share this location (2880 Broadway)

For security reasons, you can not access the url of an iframe served on another domain.
How can I get the value of flashvars attribute?
<embed src="http://wl2static.lsl.com/common/flash/as3/MemberApplet026.swf"
id="opera_elb" width="100%"
height="100%"
allowscriptaccess="always"
allowfullscreen="true"
bgcolor="ffe8ef"
quality="high"
pluginspage="http://www.macromedia.com/go/getflashplayer"
type="application/x-shockwave-flash"
flashvars="muteaudio=0&ishd=1&ishq=0&twoway=0&proxyip=">
I am using getElementsByTagName to get the element.
var Em = content.document.getElementsByTagName('embed');
And replace values in flashvars
<script>
function myFunction()
{
var Em = content.document.getElementsByTagName('embed');
var str = Em[0].getAttribute('flashvars').innerHTML;
var res = str.replace("muteaudio=0","muteaudio=1");
document.getElementsByTagName("embed").innerHTML=res;
}
</script>
But when I try error: Uncaught ReferenceError: content is not defined
please help me.
Okay so here is a solution (strictly to change the attribute of flashvars!). First I think you have a few syntax errors within your JS. So I modified it and here is the JS:
function myFunction()
{
var Em = document.getElementById('vid');
var str = Em.getAttribute('flashvars');
var contentSpot = document.getElementById("he");
contentSpot.innerHTML = Em.getAttribute('flashvars');
Em.setAttribute('flashvars', 'muteaudio=1')
// contentSpot.innerHTML = Em.getAttribute('flashvars');/* I used this to see if the change occurred.*/
}
window.onload = myFunction();
So contentSpot is a div element I created to observe the change.
the html is here:
<embed id="vid" src="http://wl2static.lsl.com/common/flash/as3/MemberApplet026.swf"
id="opera_elb" width="100%"
height="100%"
allowscriptaccess="always"
allowfullscreen="true"
bgcolor="ffe8ef"
quality="high"
pluginspage="http://www.macromedia.com/go/getflashplayer"
type="application/x-shockwave-flash"
flashvars="muteaudio=0&ishd=1&ishq=0&twoway=0&proxyip=">
<div id="he"> Hello</div> <!-- The created div to observe -->
Okay so here is my suggestion:
1)pop in the cleaned up code into a jsfiddle, then observe the content.
2)Then remove the line: contentSpot.innerHTML = Em.getAttribute('flashvars'); above the code: Em.setAttribute('flashvars', 'muteaudio=1').
3) remove comments slashes and then hit ctrl + enter to observe the attribute change.
*really watch your "."/DOM syntax and case sensitivity.
Hope this helps you out!
So I'm currently developing a Magento Website. I set up a rotator using the code found here:
http://www.magentocommerce.com/wiki/4_-_themes_and_template_customization/cms_and_home_page/javascript_banner_rotator_for_home_page
If I put the code into the homepage it works as it's supposed to. However if I put the code within a static block CDATA forces itself into the code, breaking it. I'm unable to remove the CDATA as it keeps replacing itself. Code Below:
<script type="text/javascript">// <![CDATA[
var imgs1 = new Array("{{media url="wysiwyg/rotator-1-1.jpg"}}","{{media url="wysiwyg/rotator-1-2.jpg"}}","{{media url="wysiwyg/rotator-1-3.jpg"}}");
var lnks1 = new Array("http://www.example.com/","http://www.example.com/","http://www.example.com/");
var alt1 = new Array("That Looks Nice","That Looks Nice","That Looks Nice");
var currentAd1 = 0;
var imgCt1 = 3;
function cycle1() {
if (currentAd1 == imgCt1) {
currentAd1 = 0;
}
var banner1 = document.getElementById('adBanner1');
var link1 = document.getElementById('adLink1');
banner1.src=imgs1[currentAd1]
banner1.alt=alt1[currentAd1]
document.getElementById('adLink1').href=lnks1[currentAd1]
currentAd1++;
}
window.setInterval("cycle1()",4000);
// ]]></script>
<p><a id="adLink1" target="_top"> <img id="adBanner1" src="{{media url="wysiwyg/rotator-1-1.jpg"}}" alt="" width="235" height="250" border="0" /></a></p>
Any help would be appreciated.
You are commenting the javascript ending </script> tag, try putting </script> after the line CDATA ends.
Not sure about this, but worth a try.
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:
http://www.4shared.com/zip/YTB8uJKE/flash_uploader.html
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

You can't programmatically call browse(), it has to be from a mouse click inside Flash: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/FileReference.html#browse()
In Flash Player 10 and Flash Player 9 Update 5, you can only call
this method successfully in response to a user event (for example, in
an event handler for a mouse click or keypress event). Otherwise,
calling this method results in Flash Player throwing an Error
exception.
after a day reading I know that it is impossible for security reasons.
then you can't open file reference with addCallback javascript code any way. for more information read fileReference browse from js, simulate keypress in flash workaround
Thanks again

I've implemented a facebook like button into my (html) website. Now german data protection laws want webpages to be opt-in. Other websites do this by not immediately showing the facebook like but instead showing a button saying "activate facebook button" and when this button is clicked they replace it with the real facebook button.
So it requires two clicks, but this is ok for me. An example is this webpage.
I know html and php but got no clues about javascript (yet). I'd like to know how to implement this: how can I replace the fake button with the facebook one upon clicking?
Looking in their source, they site is using a function they called button2iframe - here it is:
function button2iframe(id,link){
//alert(id);
var substr = link.split("?");
var url = substr[0];
substr.reverse();
substr.pop();
substr.reverse();
var params = substr.join("?");
params = params.split("&");
var k;
var param = "";
var paramname = "";
for( var k=0; k<params.length; k++ ) {
param = params[k].split("=");
if(param.length>1){
if(param.length>2){
paramname = param[0];
param.reverse();
param.pop();
param.reverse();
param[1] = param.join("=");
param[0] = paramname;
}
param[1] = encodeURIComponent(param[1]);
}
params[k] = param.join("=");
}
params = params.join("&");
link = url+"?"+params;
jQuery(function ($) {
$("#"+id).html($('<iframe allowtransparency="true" frameborder="0" scrolling="no" src="'+link+'" id="iframe_'+id+'"/>'));
});
}
And this is what the associated markup for the facebook button looks like:
<li class="wpsoptin_facebook" id="wpsoptin_facebook_39429">
<div class="wpsoptin_medium">
<a class="wpsoptin_sharerlink" href="javascript:button2iframe('wpsoptin_facebook_39429','FACEBOOK LIKE BUTTON IFRAM URL GOES HERE')">Facebook aktivieren</a>
<div class="wpsoptin_sharerend"></div>
</div>
</li>
This code requires you include jQuery in your site as well.
try this if you dont want to use jquery, just remove the couple of line provided Nathan Anderson good answer
//jQuery(function ($) {
// $("#"+id).html($());
document.getElementById(id).innerHTML = '<iframe allowtransparency="true" frameborder="0" scrolling="no" src="'+link+'" id="iframe_'+id+'"/>'
///});
