Ext is not defined - asp.net

I'm trying to implement a TinyMCE plugin with ExtJs, with a demo as example, found here: link.
This fails because I receive an "Ext is not defined" error in Firebug. I basically copied the example, I only used a newer version of Ext. First of all the css and scripts are included:
<link href="scripts/extjs/resources/css/ext-all.css" rel="stylesheet" type="text/css" />
<script src="scripts/extjs/ext-all.js" type="text/javascript"></script>
<script src="scripts/miframe/miframe-min.js" type="text/javascript"></script>
<script src="scripts/tinymce/jscripts/tiny_mce/tiny_mce_src.js" type="text/javascript"></script>
<script src="scripts/ux/Ext.ux.TinyMCE.js" type="text/javascript"></script>
Firebug does not complain, all the scripts are found on the specified paths and are included.
Next I call the Ext function in the head of my aspx document,
<script type="text/javascript">
console.log("Ready...");
Ext.onReady(function() {
console.log("set...");
Ext.get("cmdOpen").on("click", function() {
console.log("GO");
var dlg = new Ext.Window({
//etc
</script>
The console.log("Ready...") shows up in the console, then the code breaks. There are four references to "Ext is not defined", in ext-all.js(), miframe-min.js(), Ext.ux.TinyMCE.js() and in the code in the .aspx file. (Default.aspx)
I did not alter any aspect of the included files, they are official releases.
Am I perhaps missing a statement somewhere? Or do I have to include other things still? I have honestly no clue.

Even when including ext-all(-debug).js, you still need to include the ext-base.js file before that, otherwise you will get the "Ext is not defined error". Not sure by your last comment if you are already past this or not, but I thought I would point it out. Please see this page for complete details on how your includes should be set up:
http://www.extjs.com/learn/Tutorial:HTML_Page_Setup

there is a firefox extension called "jsview", it allows you to see what scripts and css files are included on a page.
When navigating to the link you include at the top of your post and opening the ExtJs file, you'll notice that the example provided is using version 2.1 of the code.
The Ext.ux.TinyMCE v0.6 has a corresponding blog post here. You will notice that it specifically requires:
Firefox 2+, Opera 9+, MSIE 7
ExtJS 2.1
TinyMCE 3.1.0.1
Ext.ux.ManagedIframePanel
Be aware that when plugging in a newer versions of the TinyMCE or ExtJs libraries, there might (read will) be breaking changes that you will then have to resolve. You could try scrape the files directly from the example to ensure you have a working version.
If you choose to use ExtJs v3+, get the latest components:
1) ux.ManagedIframe has been maintained more recently and even upgraded for ExtJS 3.x here
2) Read through the ux.TinyMce thread and download the latest version. I think it's 0.7b. If you're still having problems, that's probably the best place to find answers.

copy the lib folder in your eclipse workspace`s exjts project folder and just give the relative paths, is should than work

Go to ExtJs website and make sure you download and included all the necessary files and IN ORDER,also using a newer version might break the code.
try it with simpler examples and only reference the ext stuff and see if it loads

Which MathJax CDN script should be used?

I would like to use MathJax within my website, and I have opted to use a CDN method. MathJax.org states that you can put
<script
src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-MML-AM_CHTML'>
</script>
within the HTML <head></head> tags and provided a pre-populated example on jsbin
However, I have noticed when using MathJax within WordPress, the MathJax documentation suggests using
<script type="text/javascript"
src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>
I have noticed, that the difference is in the main part of the src address where the CDN used is cdn.mathjax.org instead of cdnjs.cloudflare.com, and the address points to mathjax/latest/MathJax.js instead of mathjax/2.7.2/MathJax.js.
I have put the second script into the jsbin example to see if there is a difference in function, and the example still works. Is it preferable (or more correct) to use the second script over the first one whether using WordPress or not, with the understanding that the second one will point to the most up-to-date version of MathJax?
As #Bob__ pointed out, and I had just read prior to then, MathJax was shutting down its CDN and they actually
retired cdn.mathjax.org in April, 2017.(Source: docs.mathjax.org)
The same webpage states that there are many free CDN providers that provide copies of MathJax. Some provide “rolling releases”, i.e., links that update to the latest available version upon release, and cdnjs.com is recommended. This matches Mathjax.org's page at https://www.mathjax.org/cdn-shutting-down/
They say
To jump start using cdnjs, you accomplish the first step by putting
<script type="text/javascript" async
src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-MML-AM_CHTML">
</script>
into the <head> block of your document
Note: the configuration file TeX-MML-AM_CHTML is a great way test all input options at once. You can find leaner combined configuration packages in MathJax documentation.
Interestingly, before seeing that, carrying out a MathJax libraries search on cdnjs.com provides an updated script tag of
<script
src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.3/MathJax.js">
</script>
So the answer is to check for the latest library script tag in cdnjs.com, which is currently for version 2.7.3 and use that one. Currently
<script
src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.3/MathJax.js">
</script>
and if you wish to use the TeX-MML-AM_CHTML configuration file, use:
<script
src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.3/MathJax.js?config=TeX-MML-AM_CHTML">
</script>

Why are there ?v=4.6.3 parameters for fonts in CSS? [duplicate]

I have been looking at a HTML 5 boilerplate template (from http://html5boilerplate.com/) and noticed the use of "?v=1" in URLs when referring to CSS and JavaScript files.
What does appending "?v=1" to CSS and JavaScript URLs in link and script tags do?
Not all JavaScript URLs have the "?v=1" (example from the sample below: js/modernizr-1.5.min.js). Is there a reason why this is the case?
Sample from their index.html:
<!-- CSS : implied media="all" -->
<link rel="stylesheet" href="css/style.css?v=1">
<!-- For the less-enabled mobile browsers like Opera Mini -->
<link rel="stylesheet" media="handheld" href="css/handheld.css?v=1">
<!-- All JavaScript at the bottom, except for Modernizr which enables HTML5 elements & feature detects -->
<script src="js/modernizr-1.5.min.js"></script>
<!------ Some lines removed ------>
<script src="js/plugins.js?v=1"></script>
<script src="js/script.js?v=1"></script>
<!--[if lt IE 7 ]>
<script src="js/dd_belatedpng.js?v=1"></script>
<![endif]-->
<!-- yui profiler and profileviewer - remove for production -->
<script src="js/profiling/yahoo-profiling.min.js?v=1"></script>
<script src="js/profiling/config.js?v=1"></script>
<!-- end profiling code -->
These are usually to make sure that the browser gets a new version when the site gets updated with a new version, e.g. as part of our build process we'd have something like this:
/Resources/Combined.css?v=x.x.x.buildnumber
Since this changes with every new code push, the client's forced to grab a new version, just because of the querystring. Look at this page (at the time of this answer) for example:
<link ... href="http://sstatic.net/stackoverflow/all.css?v=c298c7f8233d">
I think instead of a revision number the SO team went with a file hash, which is an even better approach, even with a new release, the browsers only forced to grab a new version when the file actually changes.
Both of these approaches allow you to set the cache header to something ridiculously long, say 20 years...yet when it changes, you don't have to worry about that cache header, the browser sees a different querystring and treats it as a different, new file.
This makes sure you are getting the latest version from of the css or js file from the server.
And later you can append "?v=2" if you have a newer version and "?v=3", "?v=4" and so on.
Note that you can use any querystring, 'v' is not a must for example:
"?blah=1" will work as well.
And
"?xyz=1002" will work.
And this is a common technique because browsers are now caching js and css files better and longer.
The hash solution is nice but not really human readable when you want to know what version of file is sitting in your local web folder. The solution is to date/time stamp your version so you can easily compare it against your server file.
For example, if your .js or .css file is dated 2011-02-08 15:55:30 (last modification) then the version should equal to .js?v=20110208155530
Should be easy to read properties of any file in any language. In ASP.Net it's really easy...
".js?v=" + File.GetLastWriteTime(HttpContext.Current.Request.PhysicalApplicationPath + filename).ToString("yyMMddHHHmmss");
Of coz get it nicely refactored into properties/functions first and off you go. No more excuses.
Good luck, Art.
In order to answer you questions;
"?v=1" this is written only beacuse to download a fresh copy of the css and js files instead of using from the cache of the browser.
If you mention this query string parameter at the end of your stylesheet or the js file then it forces the browser to download a new file, Due to which the recent changes in the .css and .js files are made effetive in your browser.
If you dont use this versioning then you may need to clear the cache of refresh the page in order to view the recent changes in those files.
Here is an article that explains this thing How and Why to make versioning of CSS and JS files
Javascript files are often cached by the browser for a lot longer than you might expect.
This can often result in unexpected behaviour when you release a new version of your JS file.
Therefore, it is common practice to add a QueryString parameter to the URL for the javascript file. That way, the browser caches the Javascript file with v=1. When you release a new version of your javascript file you change the url's to v=2 and the browser will be forced to download a new copy.
During development / testing of new releases, the cache can be a problem because the browser, the server and even sometimes the 3G telco (if you do mobile deployment) will cache the static content (e.g. JS, CSS, HTML, img). You can overcome this by appending version number, random number or timestamp to the URL e.g: JSP: <script src="js/excel.js?time=<%=new java.util.Date()%>"></script>
In case you're running pure HTML (instead of server pages JSP, ASP, PHP) the server won't help you. In browser, links are loaded before the JS runs, therefore you have to remove the links and load them with JS.
// front end cache bust
var cacheBust = ['js/StrUtil.js', 'js/protos.common.js', 'js/conf.js', 'bootstrap_ECP/js/init.js'];
for (i=0; i < cacheBust.length; i++){
var el = document.createElement('script');
el.src = cacheBust[i]+"?v=" + Math.random();
document.getElementsByTagName('head')[0].appendChild(el);
}
As you can read before, the ?v=1 ensures that your browser gets the version 1 of the file. When you have a new version, you just have to append a different version number and the browser will forget about the old version and loads the new one.
There is a gulp plugin which takes care of version your files during the build phase, so you don't have to do it manually. It's handy and you can easily integrate it in you build process. Here's the link: gulp-annotate
As mentioned by others, this is used for front end cache busting. To implement this, I have personally find grunt-cache-bust npm package useful.

CSS not working locally in my computer

I'm using Bootstrap to develop a website and recently I asked here a question because some custom simple lines in CSS weren't working. I discovered that using development sites such as jsfiddle or codepen, the code works but I can't still get it working in my computer.
Do I need to install do something or install something? I thought it could be an issue of not using a web server, but I've just installed XAMPP and nothing...
In the end, I'm using XAMPP, with proper path xampp_path/etsit/index.html --> localhost/etsit/index.html. This doesn't work, there's no error in the cosole. When I just click in index.html to open it with the browser, it doesn't work either.
For bootstrap, I just add these links to the body (JUST FOR YOU TO KNOW I HAVEN'T DOWNLOADED BOOTSTRAP BUT I'M USING CDN):
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<!-- Latest compiled JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
UPDATE
Sample in codepen and jsfiddle that work.
The original (it's the same code) you can find it in these other post I made.
UPDATE 2
Please, read the post entirely before editing my question and marking it as duplicate, not noticing that same question is mine and has been referenced twice in the post....
Based on your answers in the comments section, it seems as though you are not loading your CSS file. You've stated that you do indeed have a link to it in your in your code. So either a) that link is now gone (in which case you would not see it at all in your dev tools' network tab); or b) the link is incorrect (in which case you would be getting something like a 404 error in your network tab). Make sure the path to your CSS file is indeed correct and that it exists at the location that you are defining.

jQuery validation CSS to change font & text box colors stopped working

There may be a better forum for this, but here's my problem:
I'm using several different CDN sites for CSS, jQuery, jQuery Mobile, jQuery.validate, etc. Sometime in the very recent past (last few days) the CSS that jQuery validate uses stopped highlighting the affected text boxes in red, and changing the messages to a red font.
I initially thought it was the addition of blockUI.js & css, but then I noticed that all of my fiddles I created to make the bits & pieces of this project had been affected as well, and none of them had ever had blockUI added to them, so that wasn't it.
Then I thought maybe something had changed in Chrome, so I tried in Firefox, same thing. I have a remote server where I upload test code, and it was still working normally, until I reloaded the page, then the same thing. That tells me that the change occurred in one of the CDN based files.
My question is, since I don't have downloaded versions of each of the .js & .css files, how can I determine what the change was? Is it possible to download the previous version (the version numbers in my references hasn't changed, so there's no way to tell from them.
I know I can simply go create my own .css for the highlighting & font issues, but it seems like whoever hosts these various CDN's shouldn't change them underneath you? FWIW, my primary suspect is: http://jquery.bassistance.de/validate/demo/css/screen.css, especially since it hasn't been versioned. I haven't had a chance to try to verify this yet.
For reference I'm using this array of CDN locations for my current project:
<link href="http://malsup.com/jquery/block/block.css?v3" rel="stylesheet">
<link href="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.css" rel="stylesheet">
<link href="http://jquery.bassistance.de/validate/demo/css/screen.css" rel="stylesheet">
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.1.1.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.12.0/jquery.validate.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.12.0/additional-methods.js"></script>
<script type="text/javascript" src="http://malsup.github.io/jquery.blockUI.js"></script>
<script type="text/javascript" src="pcbclient.js"></script>
There is no CSS file as part of jQuery Validate. This plugin simply toggles two class names and those have always been .valid and .error.
The root of your problem is right here...
<link href="http://jquery.bassistance.de/validate/demo/css/screen.css" rel="stylesheet">
That's not a CDN link, nor is that CSS file part of the plugin. It's the CSS file used solely for the online demo page.
Everything broke for you because that URL no longer points to a CSS file. However, you should not have been hot-linking to another website's CSS file in the first place. (If it's not a URL from a CDN, it could be considered as stealing the other website's bandwidth.)
If you liked how that online demo page looked, you could have easily examined and copied its CSS properties into your own CSS file, provided that the copyright license allows it.
You might want to carefully review the rest of your file includes' URL's to make sure those are all part of an official CDN and not just hosted on these developers' websites.
It appears I was correct in surmising that the problem laid with the CSS at: http://jquery.bassistance.de/validate/demo/css/screen.css.
I still don't know what changed, but I downloaded the source from: http://jqueryvalidation.org/ (as I should have after deciding to use it), added it to my ASP.NET project and the problem has been resolved.

asp.net mvc 4 bundles and explicit file includes

I am very confused, I just started to work on the CSS for my ASP.NET MVC4 website and I don't fully understand what is happening.
Currently my mobile layout works but any changes to it causes one strange effect after another. (e.g. the forms not being displayed to the ajax-loader.gif constantly being displayed.)
I have the following in .Layout.Mobile.cshtml
#Styles.Render("~/Content/Mobile/css", "~/Content/jquerymobile/css")
<link rel="stylesheet" href="~/Content/Mobile/css/jquery.mobile-1.2.0.min.css" />
<link rel="stylesheet" href="~/Content/Mobile/css/jquery.mobile-1.2.0.css" />
<link rel="stylesheet" href="~/Content/Mobile/css/jquery.mobile.theme-1.2.0.css" />
#Scripts.Render("~/bundles/jquery", "~/bundles/jquerymobile")
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://code.jquery.com/mobile/latest/jquery.mobile.min.js"></script>
I have modified the BundleMobileConfig.cs in App_start as follows:
// bundles.Add(new StyleBundle("~/Content/Mobile/css")
// .Include("~/Content/Site.Mobile.css"));
//kludge is the above wrong...and the following needed??
bundles.Add(new StyleBundle("~/Content/Mobile/css")
.Include("~/Content/Site.Mobile.css",
"~/Content/Mobile/css/"));
I don't understand why this is NOT the default for this bundle?
Here are my questions / problems:
If you will note the stylesheets, I should not need to include the three explicit links, they should come from the bundles. But if delete any of them the site breaks.
Why won't the modified ~/Content/Mobile/css bundle pull up these css files?
For the script files I have looked at the code.jquery.com and I don't understand why I need these. My local code is the latest (i.e. jquery-1.9.1.js and jquery.mobile-1.2.0.js
I would expect that the version 1.9.1 shoud be able to replace the 1.7.1 without
problems, but it doesn't
The jquery.mobile.min.js should only be switching between a release and debug
vesion, which should not cause a problem, but it does.
I have used firebug to view what files are being loaded and I see that when I use just
the Render of the bundles without the explicit includes I don't get the files included, why not? I have read about bundles and it seems like I should just get the bundled files.
Can any one shed some light on what is happening and point me to a tutorial so I can learn
how to use how to debug CSS and bundles. I have read several and I find firebug very
useful, but I have no idea where to look next.
Try replacing your bundle code with this.
bundles.Add(new StyleBundle("~/Content/Mobile/css")
.Include("~/Content/Site.Mobile.css",
"~/Content/Mobile/jquery.mobile*"));
This should load your files without explicitly doing so.
Your right this did work! Thanks....
The strange thing is that the following did not work:
bundles.Add(new StyleBundle("~/Content/Mobile/css")
.Include("~/Content/Site.Mobile.css",
"~/Content/Mobile/css/jquery.mobile-{version}.js",
"~/Content/Mobile/css/jquery.mobile.theme-{version}.js",
"~/Content/Mobile/css/jquery.mobile.structure-{version}.js",
"~/Content/Mobile/css/"));
I understand why your example works...but don't understand why mine doesn't ... unless the version tag does not work like I expect it to....
Also I found out the jquery 1.9.1 is much different from 1.7.1 for this I had to do the following:
#Scripts.Render("~/bundles/jquery")
#Scripts.Render("~/bundles/jquerymobile")
<script src="~/Scripts/jquery-1.9.1.js"></script>
<script src="~/Scripts/jquery-migrate-1.1.1.js"></script>
<script src="~/Scripts/jquery.mobile-1.2.0.js"></script>
this works....using your example I will figure out a wild card pattern to include this as well.
