Avoiding "This Website Wants to Run the Following Add-on" in IE - javascript

I am playing an alert in IE8 if I open the home page of my application. I am using jQuery to embed the sound file in the page.
if (isAlert) {
if(!isAdded){
if ($("#beapImg").length!= 0) {
} else {
$('body').append('<embed src="'+alerts+'" id="beapImg" autostart="true" hidden="true" loop="true">');
isalertAdded=true;
}
}
}
But I am getting:
This website wants to run the following add-on: ‘Windows Media Player Core’ from ‘Microsoft Corporation’
at the top of the page. If I click Add Add Ons, then I am able to hear the sound.
Can anyone please suggest how to avoid this programmatically and advise me as to why I am getting the above alert?

How to Avoid the Warning?
If you are a web developer, you should use the safer versions of these controls. Please do not encourage your users to approve controls when safer options are pre-approved. If you are getting these warnings, you are probably using some very old sample code:
Windows Media Player: Do not use MediaPlayer.MediaPlayer.1, or other
older techniques. Use wmplayer.ocx.
QuickTime: Do not use QuickTimeCheckObject.QuickTimeCheck.1. Instead,
use QuickTime.QuickTime.
MSXML: Do not use MSXML 5.0. See this sample code to detect the
right version of MSXML in IE7.

JQuery Mobile 1.4.5 does not seem to invoke javascript on ipad

Using JQuery mobile 1.4.5 (https://jquerymobile.com/)
Ironically, everything works on desktop browsers, but I cannot seem to get anything to work when testing on an iPad ...
My stripped down page (HTML) contains the following:
<div data-role="content">
<script src="test.js"></script>
<script>
$( document ).on( 'pagecreate', function( event ) { do_something(); });
</script>
</div>
The file "test.js", contains the following code:
function do_something() {
alert('here in do_something()');
}
When testing on an iPad, all I get is a grey circle with a "spinning comet" rotating around in the circle and the page never even renders (Yes, I tried rebooting the iPad, clearing browser history/data, etc).
On all other browsers, I get the alert.
Ultimately, I am trying to load google maps into the page along with the javascript I need to manipulate various DOM elements as well as manipulate the map -- which I CAN do and is working on all other browsers -- just can't seem to get anything to work when testing on an iPad (I do not know how to view source or console messages via iPad Safari, which makes debugging a nightmare).
ANY suggestions would be helpful.
Thanks in advance.
First of all, you missed some important information like, were "all other browsers" running on your desktop machine or are we talking about other mobile devices? This is extremely important.
As you can see spinner that would mean jQuery Mobile and jQuery are loaded.
If they were successfully running on your desktop computer then you may check these:
Make sure none of your content is running on or from localhost. This will work just fine on desktop computers, but if you try to test it on any other device it will fail.
Make sure you are not using an absolute path in your jQM application, this will also fail on any remote device. I presume something similar may be the case as jQM is not able to show the first page
You will need to use a remote debugging feature. As you are using an iPad I again presume you own a Mac. Follow this tutorial: https://appletoolbox.com/2014/05/use-web-inspector-debug-mobile-safari/ as it is the only fool-proof method where you will find what was wrong. Unfortunately, if you are using Windows machine then you would need to use Chrome and Android device.
There's also a chance, some of your *.js content is loading from localhost or other sources not available to your iPad. This also may be the case as you stated above alert is not triggering on iPad. Which would mean that some major JavaScript has occurred thus blocking the load of other JavaScript content.
And there's one other foolproof method you can use that always helped me in this case. Trim your code to the bare minimum, even if that means you need to remove most of your HTML content and JavaScript. Test it, if it works, start including removed content. First include remote JavaScript content, CSS and similar. Then if it still works, start including actual HTML and code. Sooner or later you will stumble on the problematic code, missing content, or content that was not loaded into your iPad.
Thanks to all who provided some insight...
Turned out it was an external javascript file that contained a try/catch block as:
try {
// code
}
catch {
// code
}
When changed to:
try {
// code
}
catch(err) {
// code
}
... after the change was made, all tests passed !!

Opening links in external device browser with Cordova/jQuery-mobile

I have a bunch of links in my app. I added rel='external' target='_blank' to all of them.
In the Ripple emulator, or in a regular desktop browser, this works great. But on my Android (JB 4.2.2) it opens the link in the same window. Hitting "back" takes me back to the app, but everything is screwed and the app does not work as planned (script events do not react), until physically reloaded.
How do I ensure that a link opens in the device's browser? Do I need to use a Cordova plugin?
(I'm using Cordova 2.9.0, jQuery 1.10.1, jQuery Mobile 1.3.1)
This has been really fickle with Cordova/PhoneGap in the last few releases, I believe because of the InAppBrowser work which might be a solution for you.
What is working for us to launch in the external browser is:
window.open("http://myurl.com", '_system');
In our case, we want to find all external links and launch them in Safari/Chrome (and keep internal links in our Angular router). This probably isn't the most elegant solution, but we are doing this right now by capturing input events on the links and taking over the behavior like so:
$(document).on('mousedown','a', function(e) {
e.preventDefault();
var elem = $(this);
var url = elem.attr('href');
if (url.indexOf('http://') !== -1) {
window.open(url, '_system');
}
});
I hope that helps you a bit.
I had issues with Jason Farnsworth's answer still firing the default action after the user returned to the app in iOS. So after a little tweaking of his code I arrived at the following and it behaved as expected.
$(document).on('click', 'a', function (e) {
var elem = $(this);
var url = elem.attr('href');
if (url.indexOf('http://') !== -1) {
e.preventDefault();
window.open(url, '_system');
return false;
}
});
There're a few questions like this, but all of them try to use inappbrowser. I've used the following plugin:
com.byhook.cordova.chromelauncher
Just install it, as always, through cli:
cordova plugin add com.byhook.cordova.chromelauncher
And add the following JavaScript code:
ChromeLauncher.open(url)
This will:
put your app in background mode
open the existing instance of "google chrome for android" browser (according to the code, Google Play is gonna be opened if Chrome browser is not found, but i haven't tested this)
add a new tab to Chrome browser pointing to the desired URL
I've searched ages for the correct answer and managed to fix this another way besides the already given answers.
First of all, older versions of Cordova seem to break when you're using some methods on the newer versions of Android. Updating your Cordova to the latest version will bring some possible migration problems in your current project but is worth the shot of updating. Updated to Cordova 5.0 from 2.8, cost me around half an hour changing the code (just a few fixes required). Rebuilded, deployed and launched succesfully after. The back button made my app crash at the older versions of Cordova. The newer version made it work like a charm with the same line of code. Long story short, update cordova, change a few lines if required and rebuild your beauty.
Hope this will help you from not struggeling days like I did.
You Could just remove
target
attribute
Use only "rel" attribute
I hope it could solve your problem as i face that problem multiple times.

Regarding chrome fullscreen message disable

I need to disable fullscreen message ("you've gone fullscreen") coming on the top when chrome fullscreen mode is activated .
i need to do it through javascript . but it's one of the default functionality of chrome.
can any one help me out ?
It's not possible. As you pointed you it's one of the default functionality of chrome.
and I agree with the comment by mic You can't it's there for security
That message is, if you it can be disabled at all, likely a user preference. I have had my fair share of changing that kind of things for a custom "layer" over windows with an integrated browser and I can tell you it's impossible with javascript without some listener app. We created a C# listener app for that kind of thing that keeps checking a certain text file. We made javascript edit the text file and then let C# work it's hacking magic in some of the user's settings.
You could take a look at Chromium, the stripped down version of Chrome, if that would be of any help ;)
ps: To all the people going mental over changing user settings like that, our customers were old people that were unable to use a computer, and our application's purpose was to do as much as possible for them.
You cannot possibly do that as suggested by these links.

On the other note, why exactly would you want to do that?

JavaScript - shuffling audio

I am creating a webpage that uses JavaScript to shuffle a series of audio file questions and their matching drag-and-drop answers. I have successfully implemented this using the native HTML5 audio tags but also have a fallback section for IE 7/8 since these browsers cannot read the audio tag. This fallback section uses conditional comments around object and param tags as demonstrated at the end of this article here.
It works in that it does shuffle in IE, but breaks in that it displays the ugly Media Player-style controls that I had specifically hidden, as this activity uses "play sound" buttons instead of audio player controls.
If anyone needs to see specific parts of code, just let me know.
Many thanks in advance!
Two thoughts (sorry, I'm on a mac at the moment so testing in IE isn't a great option):
I see the parameters where you're trying to hide the controls, but have you also tried applying css to the object tag or to a container wrapped around it? It might be as simple as giving a wrapper div a style of display: none or visibility: hidden.
This isn't a direct answer to your question, but have you investigated any plugins such as SoundManager 2? It uses HTML5 audio with a Flash fallback; I've used it before and had success. Obviously it requires Flash on older browsers, but if that's not an issue it could be easier than trying to figure out how to hide the controls.
It's a nice little page by the way. Good luck!
To address your second question/comment: using an object/embed tag means that you're relying on the browser/OS deciding on what plugin it will use to play audio. Some Googling turns up issues with IE and quicktime, and one possible solution:
Jan 2009 Microsoft update breaks mp3 sound objects in IE7
IE issues with quicktime
Hope it helps. SoundManager 2 might be worth trying if you keep hitting walls, just be aware that using SM2 will mandate that users with older browsers have Flash installed and unblocked.
I’ve managed to out the second issue with the audio in IE – for the shuffle script to work with the audio in IE, you have to call the shuffle BEFORE the audio code – in my case I moved all the conditional comments below the .shuffle(); stuff and it works no worries!

'Firebug' for iPad

I have a site that uses javascript to launch a css overlay of a google map (see [link deleted because I can only have one at a time] and click the 'Enlarge' button under the map).
This doesn't work on the ipad. I believe it has something to do with this not being a link, but using the jquery live('click',.. approach. I need to fix this but I'm new to using the ipad and I don't even know how to step through the javascript to see what the problem is.
What kind of development tools are available for testing on the ipad?
Edit: My mistake. The link above works fine in the iPad - no problem bringing up the larger map. However the sister site http://lowes-realty.com/Stateline-Plaza_Enfield_CT-11.aspx is not working. What I need is a development system that will let me look at them both on the ipad (I really want to avoid emulating or spoofing).
Have you tried firebug lite?
http://getfirebug.com/firebuglite#Install
Have you tested this in google chrome? As google chrome is a webkit browser, you may be able to do the majority of your debugging in chrome, and iron out smaller issues on the iPad itself.
Edit:
Removed unnecessary comment about iPad.
The problem ended up being that I had a javascript error that aborted the script before I ever got to the jQuery code. Once I fixed that, I was able to use jQuery without making any special modifications for the ipad - awesome! I did not have to do anything with the swipe or tap events (sweet!).
However I was not able to get any kind of javascript debugger; I had to work this one out for myself. As of Nov '09 firebug lite crashed the ipad for me and there don't seem to be any developer tools build for testing the ipad. I tried several sites that claimed to perform the same way the ipad does in your browser and not one of them held water.
I have no reason to believe that there is a good option for debugging a site on an ipad (yet).
Edit A Year Later... I'm still looking for a good way to develop on an iPad. I just got Adobe Shadow up and running - it's not actually a useful tool, but there is potential (http://tv.adobe.com/watch/adobe-technology-sneaks-2012/adobe-shadow). Right now (3-29-12) the code inspector is essentially non-functional (cannot view inherited styles, can't view elements without expanding the DOM from the body element, no javascript debugging, and much more).
I know that sounds hopeless, but it has one thing going for it that nothing else I'm aware of does: Shadow works with all existing mobile devices and its code inspector is independent of device and browser. So although the inspector sucks spectacularly right now, once they build some functionality into it Shadow could be a good solution. From their site:
Shadow will be updated regularly to stay ahead of web standards, web
browser updates and support for new mobile devices entering the
market, while incorporating user feedback to provide the best
functionality and experience possible.
~ http://labs.adobe.com/technologies/shadow/
I think the problem is that on the iPhone / iPad there are no clicks events generated but instead touch events (swipe, tap).
You can use something like jQTouch (you can start reading here Getting started and then proceed to callback events hint: tap==click).
If you have more to adapt you can also look at (and wait for a stable release) of jQuery Mobile
weinre lets you remotely attach a WebKit inspector (the built-in Dev Tools you use on desktop browsers) to a page running on your mobile device (iPad/iPhone/iPod/Android/BlackBerry 6/webOS) over WiFi.
http://phonegap.github.com/weinre/images/weinre-demo.jpg
JavaScript debugging is limited to console.logs, but it's better than nothing.
If you have an ICS device, Chrome Mobile lets you remotely attach a full-featured Inspector (with full JS debugging/breakpoints) over USB. I've been thoroughly thrilled using this tool with my Galaxy Nexus.
