user3568918 has responded to the following question:
jQuery Mobile not working with Internet Explorer?
Dont forget to keep the right binding Order:
jquery mobile css
jquery script
jquery mobile script
My question is :
When I go to download page of jquery mobile
https:/ /jquerymobile.com/download/
I see two viable options for me :
Download the javascript, css and images :
https:/ /jquerymobile.com/resources/download/jquery.mobile-1.4.5.zip
Download the minified javascript :
http:/ /code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js
If I choose 1, two additional subfolders "demos" and "images" are created, which have their own sub-folders.
Do I have to reference all these subfolders in my html ?
If I choose 2, which is to download the minified javascript only, how do I reference the images that I want to use for icons?
Thanks a lot in advance.
Example: assuming your index.html is the root, you should reference:
<link rel="stylesheet" href="css/jquery.mobile.1.4.5.min.css" />
<script src="js/jquery-1.11.2.min.js"></script>
<script src="js/jquery.mobile-1.4.5.min.js"></script>
Then, the directory structure on your server shall be like this:
\index.html
-- All jQuery files shall be in \js subfolder and \css subfolder
\js\
----jquery-1.11.2.min.js
----jquery-1.11.2.min.map
----jquery.mobile-1.4.5.min.js
----jquery.mobile-1.4.5.min.map
(...other stuff)
\css\
-----jquery.mobile-1.4.5.min.css
-----jquery.mobile.external-png-1.4.5.min.css
-----jquery.mobile.icons-1.4.5.min.css
-----jquery.mobile.inline-png-1.4.5.min.css
-----jquery.mobile.inline-svg-1.4.5.min.css
(...other stuff)
\css\images\
------------ajax-loader.gif
------------icons-18-black.png
------------icons-18-white.png
(...other stuff)
\css\images\icons-png\
----------------------action-black.png
----------------------action-white.png
(...a lot of other stuff)
\css\images\icons-svg\
----------------------action-black.svg
----------------------action-white.svg
(...a lot of other stuff)
EDIT:
subfolders demos and images inside the zip file are ready for you if you need to have the JQM demos also available on your local site, there is also a custom css file special for the demos.
I think this will also clarify some aspect of your question: https://css-tricks.com/data-uris/
I just downloaded a fresh copy of tinymce, uploaded it and tried to use it on my UTF-8 encoded website.
The menu bar icons are either garbage because it can't find it's presentation file (font?) or the encoding of one of the 10000 files is wrong.
Anyone knowing this bug? I didn't change anything, just uploaded..
TinyMCE doesn't use my german lang file either, obviously. I placed the js file into the "langs" folder.
<script type="text/javascript">
tinyMCE.baseURL = '//example.com/de/assets/scripts/tinymce';
tinyMCE.suffix = '.min';
tinymce.init({
selector: "textarea"
});
</script>
Do I have to set any configuration for path, basepath, ... ??
My actual path to tinymce is scripts/tinymce/tinymce.min.js. The origin path provided by the shipped package was tinymce/tinymce/js/tinymce/tinymce.min.js but honestly this kind of nesting folders without any reason..
update: The paths are working, it does read files not directly linked.. (like theme.min.js) successfully.
I am developing an app which uses both Phonegap and JQuery Mobile.
The app connects to an external server to check for new content/content updates (html and pdf files).
If needed, in iOS those files are successfully downloaded into the app /Documents folder.
The app then retrieves each content file's absolute path (file://localhost/var/mobile/Applications/APPID/Documents/subfolder) and creates listviews that link to each file's absolute path.
The problem I am having is the following: tapping a listview opens the linked page BUT not as an ajax call. The page loads but then no javascript (cordova.js, jquery.js app.js etc) is referenced in the page and hence I can't navigate back to the main menu. It seems like the jQueryMobile ajax navigation stops working when I open html files in the /Documents folder.
This happens only for the downloaded content in the /Documents folder (and hence outside Phonegap's www folder).
From the remote debugger, if I try to call the $.mobile.changePage('previousPage.html')* function, the console returns that $ is not defined, as if the page couldn't reference jQuery. But in none of the pages in the /www folder I need to re-reference the js files.
The app uses a multipage layout and each page has its own javascript after the <div data-role="page" id="pageid"> container.
Each .html in the /Documents folder is structured as a jQueryMobile page (with data-role attributes).
This is the code that creates the listviews:
<script type="text/javascript">
$('#content').live('pagebeforeshow', function(e) {
var curCat = parseInt(window.localStorage.getItem('currentCat'));
console.log('PAGE BEFORE SHOW: CONTENT');
db.db.transaction(function(tx) {
tx.executeSql('SELECT * FROM `content` WHERE `content`.`catID` = ?', [curCat],
function(tx, result) {
var path = window.localStorage.getItem('contentPath') + '/';
if (result.rows && result.rows.length) {
var html = '<ul data-role="listview" id="linkUl">';
for (var i = 0; i < result.rows.length; i++) {
var filename = result.rows.item(i).index_file.substr(result.rows.item(i).index_file.lastIndexOf('/'));
console.log(result.rows.item(i).id);
html += '<li id="' + result.rows.item(i).id + '">';
html += '<a href="' + path + filename +'">';
html += result.rows.item(i).title;
html += '</a></li>';
}
html += '</ul>';
console.log(html);
$('#contCnt').html(html);
$('ul#linkUl').listview();
}
},
function(tx, error) {
console.log(error.code);
var html = '<div id="errorDB">';
html += 'ERROR RETRIEVING FILES';
html += '</div>';
$('#contCnt').html(html);
}
);
});
});
$('div#content').live('pageshow', function(e) {
$('ul#linkUl').listview('refresh');
});
</script>
where the ContentPath variable is stored as a fileSystem object's directory.toUrl();
My fear is that jQueryMobile can't ajax-pull html from an external directory (the /Documents folder in iOS), or that I am missing some attribute or setting in order to do so.
Perhaps because I am using an absolute url? If so, how can I get the relative url from Phonegap's /www folder?
Do I have to declare something on the cordova.plist file?
Also, the downloaded content won't have to contain any js, they should be only plain html, but I need to keep jQuery Mobile header/footer and navigation system in all the pages.
I am using Cordova 2.2.0 and the latest releases of both jQuery and jQuery mobile.
Thanks in advance and sorry if something in the formatting goes wrong, I am new to SO (in case I'll edit asap).
You can open files from the documents folder (or any other folder the app has read access to).
There are two reasons that a link may not load as an ajax page
jQuery Mobile thinks that it isn't part of the app
There is a javascript error loading the page, which causes the default link click action to run instead of the ajax loader.
You could try using a call to $.mobile.changePage instead of just setting up the links - that gives you a little bit more visibility into what is going on.
I don't think a file url in a different folder should be treated as a different domain by jQuery Mobile, but to eliminate that possibility it should be reasonably easy to construct a relative url to the documents folder.
Solved, and thanks to Tom who led me through the right direction.
I guess the problem was that jQueryMobile was interpreting the absolute path as a an external link and thus the WebView was opening the html files as a new file, detaching it from the rest of the application.
What I did was substituting the absolute path file://localhost/var/mobile/Applications/APPID/Documents/subfolder
with a relative one, which in my case is './../../Documents/subfolder/filename.html
and now it works like a charm.
I have a WebForms app that I'm converting to MVC, but for now running legacy stuff side-by-side.
For some reason, the ScriptManager left to it's own devices tries to load the following files from a very strange (and non-existent) location:
<script src="Scripts/WebForms/MsAjax/MicrosoftAjax.js" type="text/javascript"></script>
...
<script src="Scripts/WebForms/MsAjax/MicrosoftAjaxWebForms.js" type="text/javascript"></script>
I can't find the setting of that location, and googling "Scripts/WebForms/MsAjax" brings back nothing.
Changing the (obsolete) ScriptPath property on the ScriptManager does nothing to help with these two scripts.
Trying to override the Path location like the following also does not work (it just tries to load both scripts)
Scripts.Add(new ScriptReference { Name = "MicrosoftAjax.js", Path = ContextUtil.MapApplicationPath("~/My/Script/Location/MicrosoftAjax.4.0.js") });
Scripts.Add(new ScriptReference { Name = "MicrosoftAjaxWebForms.js", Path = ContextUtil.MapApplicationPath("~/Shared/Scripts/Legacy/MicrosoftAjax/MicrosoftAjaxWebForms.4.0.js") });
What I can't understand is
Why is it not loading the scripts by default from a Embedded Resource?
Where is this strange path coming from?
Why won't it accept my overridden script paths?
Can anyone help?
So I was reading this stackoverflow post about "autoversioning" in ASP.NET MVC for CSS/JS files and was wondering what the "best" strategy is to do this.
The solution provided inserts an assembly number - which means everytime you publish - it will change EVERY SINGLE file which is not ideal because if you make modifications to just 1 *.css or *.js then it will change each and every file.
1) How can it be done just for "single files" instead of using site wide assembly using modification date or something on IIS7 ?
2) Also if I have some sort of "static" asset like - http://static.domain.com/js/123.js - how can I use rewrite to send the latest file for a request if someone has integrated this static link onto their site ?
i.e. http://static.domain.com/js/123.js is the link and when a request comes for this - check and send latest file ?
ASP.NET 4.5+ comes with a built-in bundling & minification framework
which is designed to solve this problem.
If you absolutely need a simple roll-your-own solution you can use the answer below, but I would always say the correct way is to use a bundling & minification framework.
You can modify the AssemblyInfo.cs file like so:
Change
[assembly: AssemblyVersion("1.0.0.0")]
to
[assembly: AssemblyVersion("1.0.*")]
This means that every time the project is built, it will have a new assembly version which is higher than the previous one. Now you have your unique version number.
Create an UrlHelperExtension class that will help get this information when needed in the views:
public static class UrlHelperExtensions
{
public static string ContentVersioned(this UrlHelper self, string contentPath)
{
string versionedContentPath = contentPath + "?v=" + Assembly.GetAssembly(typeof(UrlHelperExtensions)).GetName().Version.ToString();
return self.Content(versionedContentPath);
}
}
You can now easily add a version number to your views in the following manner:
<link href="#Url.ContentVersioned("style.css")" rel="stylesheet" type="text/css" />
When viewing your page source you will now have something that looks like
<link href="style.css?v=1.0.4809.30029" rel="stylesheet" type="text/css" />
UPDATE: The previous version did not work on Azure, I have simplified and corrected below. (Note, for this to work in development mode with IIS Express, you will need to install URL Rewrite 2.0 from Microsoft http://www.iis.net/downloads/microsoft/url-rewrite - it uses the WebPi installer, make sure to close Visual Studio first)
If you would like to change the actual names of the files, rather than appending a querystring (which is ignored by some proxies / browsers for static files) You can follow the following steps: (I know this is an old post, but I ran across it while developing a solution:
How to do it: Auto-increment the assembly version every time the project is built, and use that number for a routed static file on the specific resources you would like to keep refreshed. (so something.js is included as something.v1234.js with 1234 automatically changing every time the project is built) - I also added some additional functionality to ensure that .min.js files are used in production and regular.js files are used when debugging (I am using WebGrease to automate the minify process) One nice thing about this solution is that it works in local / dev mode as well as production. (I am using Visual Studio 2015 / Net 4.6, but I believe this will work in earlier versions as well.
Step 1: Enable auto-increment on the assembly when built
In the AssemblyInfo.cs file (found under the "properties" section of your project change the following lines:
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]
to
[assembly: AssemblyVersion("1.0.*")]
//[assembly: AssemblyFileVersion("1.0.0.0")]
Step 2: Set up url rewrite in web.config for files with embedded version slugs (see step 3)
In web.config (the main one for the project) add the following rules in the <system.webServer> section I put it directly after the </httpProtocol> end tag.
<rewrite>
<rules>
<rule name="static-autoversion">
<match url="^(.*)([.]v[0-9]+)([.](js|css))$" />
<action type="Rewrite" url="{R:1}{R:3}" />
</rule>
<rule name="static-autoversion-min">
<match url="^(.*)([.]v[0-9]+)([.]min[.](js|css))$" />
<action type="Rewrite" url="{R:1}{R:3}" />
</rule>
</rules>
</rewrite>
Step 3: Setup Application Variables to read your current assembly version and create version slugs in your js and css files.
in Global.asax.cs (found in the root of the project) add the following code to protected void Application_Start() (after the Register lines)
// setup application variables to write versions in razor (including .min extension when not debugging)
string addMin = ".min";
if (System.Diagnostics.Debugger.IsAttached) { addMin = ""; } // don't use minified files when executing locally
Application["JSVer"] = "v" + System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString().Replace('.','0') + addMin + ".js";
Application["CSSVer"] = "v" + System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString().Replace('.', '0') + addMin + ".css";
Step 4: Change src links in Razor views using the application variables we set up in Global.asax.cs
#HttpContext.Current.Application["CSSVer"]
#HttpContext.Current.Application["JSVer"]
For example, in my _Layout.cshtml, in my head section, I have the following block of code for stylesheets:
<!-- Load all stylesheets -->
<link rel='stylesheet' href='https://fontastic.s3.amazonaws.com/8NNKTYdfdJLQS3D4kHqhLT/icons.css' />
<link rel='stylesheet' href='/Content/css/main-small.#HttpContext.Current.Application["CSSVer"]' />
<link rel='stylesheet' media='(min-width: 700px)' href='/Content/css/medium.#HttpContext.Current.Application["CSSVer"]' />
<link rel='stylesheet' media='(min-width: 700px)' href='/Content/css/large.#HttpContext.Current.Application["CSSVer"]' />
#RenderSection("PageCSS", required: false)
A couple things to notice here: 1) there is no extension on the file. 2) there is no .min either. Both of these are handled by the code in Global.asax.cs
Likewise, (also in _Layout.cs) in my javascript section: I have the following code:
<script src="~/Scripts/all3bnd100.min.js" type="text/javascript"></script>
<script src="~/Scripts/ui.#HttpContext.Current.Application["JSVer"]" type="text/javascript"></script>
#RenderSection("scripts", required: false)
The first file is a bundle of all my 3rd party libraries I've created manually with WebGrease. If I add or change any of the files in the bundle (which is rare) then I manually rename the file to all3bnd101.min.js, all3bnd102.min.js, etc... This file does not match the rewrite handler, so will remain cached on the client browser until you manually re-bundle / change the name.
The second file is ui.js (which will be written as ui.v12345123.js or ui.v12345123.min.js depending on if you are running in debug mode or not) This will be handled / rewritten. (you can set a breakpoint in Application_OnBeginRequest of Global.asax.cs to watch it work)
Full discussion on this at: Simplified Auto-Versioning of Javascript / CSS in ASP.NET MVC 5 to stop caching issues (works in Azure and Locally) With or Without URL Rewrite (including a way to do it WITHOUT URL Rewrite)
1)
Use file modification time instead. Here's an example:
public static string GeneratePathWithTime(string cssFileName)
{
var serverFilePath = server.MapPath("~/static/" + cssFileName);
var version = File.GetLastWriteTime(serverFilePath).ToString("yyyyMMddhhmmss");
return string.Format("/static/{0}/{1}", version, cssFileName);
}
This will generate a path like "/static/201109231100/style.css" for "style.css" (assuming the your style.css is located in the static directory).
You'll then add a rewrite rule in IIS to rewrite "/static/201109231100/style.css" to "/static/style.css". The version number will only be changed when the css file has been modified and only applies to modified files.
2)
You can handle the request to 123.js via an HttpModule and send the latest content of it, but I don't think you can guarantee the request gets the latest version. It depends on how the browser handles its cache. You can set an earlier expiration time (for example, one minute ago) in your response header to tell the browsers to always re-download the file, but it's all up to the browser itself to decide whether to re-download the file or not. That's why we need to generate a different path for our modified files each time we updated our files in your question 1), the browser will always try to download the file if the URL has never been visited before.
I wrote a Url Helper which does the CacheBusting for me.
public static string CacheBustedContent(this UrlHelper helper, string contentPath)
{
var path = string.Empty;
if (helper.RequestContext.HttpContext.Cache["static-resource-" + contentPath] == null)
{
var fullpath = helper.RequestContext.HttpContext.Server.MapPath(contentPath);
var md5 = GetMD5HashFromFile(fullpath);
path = helper.Content(contentPath) + "?v=" + md5;
helper.RequestContext.HttpContext.Cache.Add("static-resource-" + contentPath, path, null, System.Web.Caching.Cache.NoAbsoluteExpiration, new TimeSpan(24, 0, 0), System.Web.Caching.CacheItemPriority.Default, null);
}
else
{
path = helper.RequestContext.HttpContext.Cache["static-resource-" + contentPath].ToString();
}
return path;
}
You could replace the GetMD5HashFromFile() with CRC or any other sort of call which generates a unique string based on the contents or last-modified-date of the file.
The downside is this'll get called whenever the cache is invalidated. And if you change the file on live somehow, but don't reset the application pool, you'll probably need to touch the web.config to get it to reload correctly.
You might want to have a look at Dean Hume's Blogpost MVC and the HTML5 Application Cache. In that post, he points out an elegant way of automatically handling versioning per request, using a class library of #ShirtlessKirk:
#Url.Content("~/Content/Site.css").AppendHash(Request)
This question is really old now, but if anyone stumbles upon it, here's to my knowledge the current state of the art:
In ASP.NET Core you can use TagHelpers and simply add the asp-append-version attribute to any <link> or <script> tag:
<script src="~/js/my.js" asp-append-version="true"></script>
For both ASP.NET Core and Framework there is a NuGet Package called WebOptimizer (https://github.com/ligershark/WebOptimizer). It allows for both bundling and minification, and will also append a content-based version string to your file.
If you want to do it yourself, there is the handy IFileVersionProvider interface, which you can get from your IServiceProvider in .NET Core:
// this example assumes, you at least have a HttpContext
var fileVersionProvider = httpContext.RequestServices.GetRequiredService<IFileVersionProvider>();
string path = httpContext.Content("/css/site.css");
string pathWithVersionString = fileVersionProvider.AddFileVersionToPath(httpContext.Request.PathBase, path);
For .NET Framework, you can get the FileVersionProvider source from here: https://github.com/dotnet/aspnetcore/blob/main/src/Mvc/Mvc.Razor/src/Infrastructure/DefaultFileVersionProvider.cs
You will have to do some work, like replacing the Cache with MemoryCache.Default or a ConcurrentDictionary or something, but the 'meat' is there.
