I want to include the URL of jQuery UI http://code.jquery.com/ui/1.9.0/jquery-ui.js in my JSF page. I saw many questions which said <h:outputScript> should be used, but in none of the answers I saw an example as to how to include an URL. The answers were only relevant if the js file is present in some folder of the project.
Can someone please help where I have to include it in my page?
Just use plain HTML <script> element the usual way.
<script src="http://code.jquery.com/ui/1.9.0/jquery-ui.js"></script>
The <h:outputScript> can only refer local scripts. You'll only miss its dynamic versioning, modularity and relocation advantages, but that should technically not harm for a static and external script.
It's however possible to use a custom ResourceHandler to change the URL of a <h:outputScript> to be an external URL for pure CDN purposes. OmniFaces CDNResourceHandler is such an example.
Unrelated to the concrete problem, PrimeFaces components are built around jQuery/UI. Are you absolutely positive that you need a separate instance of jQuery UI library?

I have created a custom XBL component that includes very little markup. It primarily consists of CSS, JavaScript and a <div>. The JavaScript then writes the markup to the DOM, inside the <div>. Its CSS specifies styles for a lot of specific element IDs. This works just fine in Form Runner, but not with the Server Side Embedding API.
The Server Side Embedding API appears to be rewriting the CSS file. It prefixes all the CSS selectors for specific IDs with o0. For example #MultiMousePosition-cwm is changed to #o0MultiMousePosition-cwm. This might work fine if the markup of the elements were included in the XBL component. Then it could be rewritten. But since the markup is generated by JavaScript after the page is loaded, this doesn't happen.
Is the rewrite of CSS and element IDs done in case the API is used to include multiple forms in the same page?
Is there a way to prevent the CSS from being rewritten? Or is there some other way to deal with this problem?
I tried to use <xxbl:global> but it looks like that won't work for CSS resources.
The JavaScript is a complex library created by another developer and rewriting it to avoid this issue would take a significant amount of work, if it is possible.
The rewrite of ids is done to prevent id conflicts in the resulting HTML page. That can include supporting multiple forms, but also possible conflicts with other content on the page.
Currently there is no way to disable rewriting. It wouldn't be hard to add as a configuration property, possibly on the XBL components (though some things would need to be rewritten on some not, which might make the configuration more difficult), or globally, for users who know for sure they won't have id conflicts.
I am starting a jquery mobile/phonegap application. And would like to know if there is any way I can keep my code in seperate files so it is easier to manage. From all the reading I have done on jquery mobile it looks like all of your pages are in one file and are just seperated by divs like <div data-role="page" id="page-one"></div>. I guess I could try to make some type of a makefile that concatenated them all together, but it seems that most apps are pretty lengthy that they should have a solution for this. Keeping all the code in one file just seems impossible to maintain.
JQuery demo, three pages, all one source file:
http://demos.jquerymobile.com/1.1.0/docs/pages/multipage-template.html
You can just use normal links with jQuery mobile:
http://demos.jquerymobile.com/1.4.0/navigation/
It will "hijack" the link and use transitions to give you a native like animation. As Flatlineato pointed out you need to make each page confirm to the required markup, and you'll need to repeat your headers/footers etc on each included page.
Or you can use more complex solutions to dynamically change the content of your page, which can be stored in multiple files, like this other SO post:
including the header and footer in jquery mobile multiple page site
But I would also agree with Leo and say the jQuery mobile isn't the best choice for Phonegap, it's not that well optimized, and runs slower in the Phonegap webkit view than it does in native safari.
I've also switched to a custom navigation system and dropped jQM early on in my Phonegap development, but that was over a year ago, more recent versions may work better.
I think my personal API is what you are searching for:
https://github.com/charnekin/api
Demo example:
http://yopo.es/cordovapi/
jQuery Mobile allows you to have the pages in separate files. Obviously in each file must conform to the structure of the markup pages.
To point to another page in the link instead of the id you specify the correct file name. If the file then you enter multiple jquery mobile pages must also specify the id.
Im bulding a website using MVC4. Recently I've read about TypeScript. It looks really nice however I cannot find any use for it in a MVC website. Am I missing something? Do you use it? Where?
TypeScript is a pre-compiler for JavaScript. Hence you can use TypeScript only as a replacement for JavaScript (server-side, e.g. Node.js, or client-side, i.e. in the browser).
As you are probably writing MVC4 code with C#, TypeScript will be of no use for you in relation to MVC4.
Regarding the client-side it's somewhat different.
I guess the main point you need to know is that TypeScript is not (yet) just another language on the server, that you can exchange with C#.
I find it quite useful for building largish apps with lots of logic on the client. The interfaces help avoid some errors. It compiles to javascript so you could use it instead of javascript. If you're just writing a couple of lines I wouldn't bother though.
You can link to the generated javascript files from TS files directly in the script bundles or HTML. If you want to automatically link to many JS files, use require JS. This will save you having to link to many js files.
I am getting ready to code a number of HTML helpers for UI elements in an ASP.NET MVC 3 project. I expect many of the helpers to depend on code that is located in external javascript libraries. These could be custom javascript libraries that I write, or they could reference 3rd party libraries like jQuery and jQueryUI. For example, I might write HTML.RichM.DataPicker(...) that would require the page to have jQuery and jQueryUI referenced and some code executed in the document ready function. Getting code into the document ready function is pretty straightforward I guess -- I could simply inject a new script block into the output with the contents of the function, even though that would mean I might have a page peppered with document ready functions all over.
The other part of this is making sure that the jQuery and jQuery UI libraries (in my example) are referenced and included. Is there an "MVC way" to add the code references to the view page or the layout/master if they are not already there, or must I instruct users of my HTML helpers that they need to add references manually for any required javascript files? Of course, I could just instruct them to include all possible external library references in the master or layout page, but that seems like overkill. In ASP.NET Web Forms, for example, I might have used RegisterClientStartupScript or RegisterStartupScript to do this from my custom control.
Thanks for any suggestions!
I think the easiest way is to include the dependant scripts in the header, that's maybe not what you want to do, but I think it's the easiest way.
I suggest you using a tool like SquishIt to bundle your JS files together, that way, you will not have to load like 20 js files, it will be more efficient and cleaner.
Ok so this is a little random but..
Using MVC 3 (with Razor view engine) with Knockout.js which uses jQuery Templating i've come across a little problem i'm sure is possible to solve.
In order to use jQuery-Tmpl you need to supply a template in
<script type="text/html">
...template elements go here...
</script>
Now the problem is that the razor view engine doesn't seem to generate HTML inside of these specific script tags. It handles standard html, (script type="text/javascript") fine but appears to just not do anything with the aforementioned script tag.
Does anyone know how to get around this issue i.e. how to use MVC 3 Razor with jQuery-Tmpl?
There is a pretty good solution in this blog post: http://www.wiredprairie.us/blog/index.php/archives/1204
This creates a "template" helper that emits the script start/end tags.
Otherwise, I have some ideas for putting templates in external files, which would be another way to avoid this issue. It involves storing the templates in .html files and injecting them into the page into script tags. There are certainly many ways that this could be accomplished though on the client or server side, just a few ideas.
A more general approach if you want to keep things in the document is using #Html.Raw to output html without affecting the edit-time syntax state.
For example:
#Html.Raw("<script type='text/x-dot-template' id='awesome_template'>")
<!-- insert some awesomeness here -->
#Html.Raw("</script>")
I happen to like the helper method suggested above a little better, but it has not always been something I was able to implement, so this is an alternative with its own benefits (namely clarity over ease of use and terseness)
