I've been fooling around with videojs and I'd like to register a plugin for some code that I grabbed over on Github my forked code. I followed the setup directions indicated by original author, however when the script goes to self register I get a javascript error on this line:
videojs.plugin('thumbnails', function(options) {
which gives error Uncaught Reference error : videojs is undefined I referred to the docs for videojs where it's says to register a plugin using the call
vjs.plugin('examplePlugin', examplePlugin);
seen at this link. So I was hoping a quick fix would be to just change videojs to vjs but no such luck! Where am I supposed to declare vjs/videojs and as what? as it's not mentioned in the plugin docs. So basically how do you properly register plugins?
Have you done the following?
<script src="/path/to/video.js"></script>
Doing this should include the necessary files that declare vjs and its extended name videojs.
These are both decalred in the above script.
Either vjs or videojs should work if you have done so.
Also, make sure that you have included video.js before your plugin registration. If you have done so, then I believe what you are doing should work fine.
According to the demo included in the vjs download, keep the script include for video.js in the <head> tags to be compatible with older browsers.

I am working with this demo: http://cssdeck.com/labs/setting-active-states-on-sticky-navigations-while-scrolling/
For some reason when I try to recreate it the Java part making the navigation work isn't coming through on my version here: http://cssdeck.com/labs/ydsxavxy
So far I saved out index.html, style.css, and flip.js and attempted to link the CSS and JS in the index.
How can I get my version working like the demo? How is a Java file included outside of CSSDeck? I am not too familiar with how CSSDeck takes the HTML, CSS, and Java and combines them into one page preview.
The version of jQuery you are loading is not correct.
The example that works uses 1.8, and you are loading 1.4:
<script class="cssdeck" src="//cdnjs.cloudflare.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
You can easily know this by looking at your browser console and seeing what errors it's throwing. In your case, the error is as follows:
TypeError: $(...).on is not a function
This usually means your jQuery library is not defined or not supported by the code you're using.
i want to put a soundcloud music player (http://stratus.sc/) on my drupalgardens page. i added an external source javascript library and uploaded a js file on the system as it says on the pluging website. all this tru the administration website of drupalgardens. When i check the sourcecode of my webpage it appears like the pluging is on the header. But it doesnt work, i cant see it. i activated all the jquery functions.
bit of sourcecode on header where the pluging seems there:
<script type="text/javascript" src="http://stratus.sc/stratus.js"></script>
<script type="text/javascript" src="http://NAMEOFMYSITE/sites/NAMEOFMYSITE/files/js/js_PRNQJr2GPf-FrbaSuV5IDQ1l6Lfby6e79KpPOUTf5kI.js"></script>
link:

Any suggestions?
Note : The player im talking about is NOT the one that can be seen under the rotating banner. the one im talking about its supposed to be globally on the webpage at its seem on the pluging oficcial webpage
For one you're getting this console error: "Uncaught SyntaxError: Unexpected token < "
Not sure how that script is getting added but just removing the script tags may clear it up.
Even if the frame errors mentioned by KG are unrelated, you have to go clean that all up.
Your script should also be loaded after jquery. Since it looks like you have js aggregation turned on, I don't really know how to determine if drupal is loading things correctly. You can just tell your script to load in the footer instead of header if you're unsure. The links below explain how to do that.
Here are some javascript related resources for Drupal. They sometimes expect things to be handled differently.
The plugin is dependent on jQuery. By default, Drupal 7 loads jQuery 1.4. You may need to use the jQuery Update plugin to use 1.5, 1.7 or 1.8
Drupal Community docs about javascript:
http://drupal.org/node/756722
Drupal javascript API:
http://drupal.org/node/751744
I had a similar issue. Some reasons for a not working player are:
For some reason $ is not known (although jQuery is included). I replaced '$' by 'jQuery' and everything worked fine. That means use jquery(document).ready(... instead of $(document).ready(... and jQuery.stratus({.. instead of $.stratus({...
There is a typo on the stratos.sc web site. It should read $.stratus not $stratus (or jQuery.stratus, see previous hint).
Check that the source stratus.js and the initialisation code is included.
Mixture of https and http might be a good guess as reason for problems, but actually it works (I just tried it). If you can't find the problem, try to use a JavaScript debugger and check the error logs first!
Background
I have a snippet of javascript that sites on customer pages. When this script is executed, it loads necessary assets and scripts and then executes the main code.
One of the script's I'm loading is Twitter's bootstrap JS to create a modal window. It's implemented as a jQuery plugin, and adds '$.modal()' to a jquery object.
Problem
This works on all but one customer site. On this particular site, as I invoke $('#idOfWindow').modal();, the page throws a javascript error Object has no method 'modal'
I've verified that the bootstrap code is invoked, and $.fn.modal is called to setup the plugin, My hunch is that something is clobbering the jQuery object, but I'm not sure how to debug this.
Comments
I'm currently using Chrome's Developer Tools to Debug, and I have verified that the plugin is loaded and executed before it's ever called. The client site is using jQuery 1.7.2. I'm familiar with chrome tools, but I'm not a power user.
If you are right, that your original jQuery object is being overwritten somewhere, you should be able to restore it with jQuery.noConflict().
Demo: jsfiddle.net/KthZu
Edit: Some debugging tips:
To help in debugging, you can check the jQuery version in the console with this code:
$().jquery
Another potential debugging trick would be to store a reference to jQuery when you create you plugin.
$.fn.myPlugin = function(){};
window.jQueryWithMyPlugin = $;
Then, when debugging, you can plainly see if window.$ has been overwritten:
$ === jQueryWithMyPlugin
Generally for any widget type of code that is to be embedded externally, you'll want to wrap your code:
(function($){
$('#idOfWindow').modal();
})(jQuery);
I have, in the past had issues where multiple versions of jQuery (or jQuery & prototype) were loaded on the same page. Be sure that the version of jQuery you're adding $.fn.modal to is identical to the version that's being called. $().jquery can be used to access the specific version of jQuery in use.
Okay, I have been working for quite some time on a website for a friend..
My coding skills are .. questionable, and I've been having quite a few problems.
Currently the jQuery on my site simply stopped working, I could not find the reason, and I have done everything I could to try to get it to work.
( I have followed countless guides all over the internet, for troubleshooting etc. and I still cannot get it to work)
-EDIT-
I have moved all the files to the top of the code.. Yet the problem persists.
Sincerely yours, Malmoc
You are trying to use jQuery code before jQuery.js is loaded.
jQuery.js must load before any dependent code or plugins. Use a browser console and look at errors thrown on page load. "$" is not defined error is a quick indication of loading problem with jQuery
Think of it this way. jQuery library contains a number of functions, including defining "$". If these functions or "$" aren't already available when you call them, they are undefined and errors get thrown and your code won't work
Once you have jQuery script tag before other code, you may still run into complications if you recently added prototype library which also uses "$" alias. This can cause conflicts but there is a workaround using jQuery.noConflict()
Very odd, I suggest you set the source to jQuery to the website here:
http://code.jquery.com/jquery-1.8.2.min.js
Seems to be quicker response time, and in your source code you appear to link jQuery twice, that may be causing some issues.
Your $ is also getting overwritten by another script. Best that you use jQuery.noConflict() for this
http://api.jquery.com/jQuery.noConflict/
And then you can put your code in a closure like this:
(function(){
var $ = jQuery;
// jQuery code using $
})(this);
Looks like you're mixing mootools and jquery. Please resolve your conflict between jquery's $ namespace and mootools' $ namespace.
google "jquery no conflict"
I have this error while trying to run mediaelement player.
The error is reported at mediaelement-and-player.min.js:44.
Edit: My apologies, I posted this from the mediaelementjs.com Support website.
I was trying to use mediaelement.js to play audio on my website.
Edit 8/2: The interesting thing is that when i load the full mediaelement-and-player.js instead of the minified version, it works fine.
I just dealt with this same issue while trying to use the Drupal module, http://drupal.org/project/mediaelement.
Turns out that a core Drupal javascript file, drupal.js, was calling jQuery.noConflict() which removes the $ variable from being defined in the global scope, hence bringing this bug in mediaelement-and-player.js to light.
This was reported in the issue queue for the mediaelement project and it looks like the fix just got committed: https://github.com/johndyer/mediaelement/pull/570
Most likely you have not loaded the jquery library into your script.
You have to reference the library (a js file) from within the header of your page via url. The url can point to a copy pf jquery you keep local or to a public site.
