There appear to be changes in the way jQuery Mobile handles icons starting from v 1.4. For instance
Delete
now the generated markup reads
<a href="index.html" data-role="button" data-icon="delete" class="ui-link ui-btn ui-icon-delete
ui-btn-icon-left ui-shadow ui-corner-all" role="button">
"Delete"
::after
</a>
The after pseudo class appears to use markup from the corresponding icons.min.css file which reads
.ui-icon-delete:after
{
background-image: url("data:image/svg+xml;
charset=US-ASCII,%3C%3Fxml%20version%3D%221.0%22..g%3E");
}
As far as I can tell the icon images in the /images folder do not get used at all. No issues with this since it seems to work. However, I would be most grateful to anyone who might be able to explain these changes. Also, why do they insist on supplying two separate .min.css files - one only for the SVG images.
...A while later
Hmmm... I looked into this a bit more and still even more puzzled. The jquery.mobile.icons.css file does not change and neither do the images in the icons-png folder. Why do they not just get people to link to them from their CDN?
The SVG spec is extensive and no browser currently supports the entire spec. That being said all the latest versions of all the major browsers have basic SVG support. Since none of them have complete support you'll need to check individual features in each browser you're targeting.
jQuery Mobile tries to provide all around support, not like Sencha Touch which only provided support for we-kit browsers, at least initially.
Reason for 2 separate implementations are support for older browsers. If older browser is detected it would gracefully switch to PNG icons, as it used to be.
Update:
jQuery Mobile has 2 separate CSS file structures:
First one is: http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.css
This one has everything inside, support for bot kind of icons and everything is part of CDN repository.
For example, here's an icon set from CDN repository.
Second one is: http://code.jquery.com/mobile/1.4.2/jquery.mobile.structure-1.4.2.min.css
This one holds only core jQuery Mobile CSS, it is used with Theme Roller. When you download theme from themeroller you will find everything you need for full jQuery Mobile customization, including incons.
If you want icons to be part of CDN and you are using your own theme just open jquery.mobile-1.4.2.min.css, copy it initial CSS dealing with icons and place it inside jquery.mobile.structure-1.4.2.min.css. There's no point ion creating numerous numbers of CSS files which will cover everyone's needs. At some point you need to do something by yourself.
Thou, and I would agree with this, it is shame why jQuery Mobile developers didn't create custom CSS down loader like they did for JavaScript.

I have not been able to get an explanation of which files are needed in a JQuery Mobile Web site. The stackoverflow documentation on JQuery Mobile shows that there is one file for css and one file for js:
jquery.mobile-1.4.5.min.css
jquery.mobile-1.4.5.min.js
However, downloading the JQuery Mobile 1.4.5 package one ends up with many more. All files that have ".min" appended to the name of the asset, is a minimized version.
The standard download includes one js (the one mentioned above). That is required, as well as JQuery itself. At this date, the latest jQuery that is compatible with jQuery Mobile 1.4.5:
jquery-2.2.4.js
(correct me if that is not true)
For css files standard download includes:
jquery.mobile-1.4.5.css
jquery.mobile.structure-1.4.5.css
jquery.mobile.theme-1.4.5.css
jquery.mobile.external-png-1.4.5.css
jquery.mobile.icons-1.4.5.css
jquery.mobile.inline-png-1.4.5.css
jquery.mobile.inline-svg-1.4.5.css
It appears to me that the first file contains all the rest. So that one can choose to include all at once with one file. The others, I guess, would be used if less code is wanted in a streamlined version of JQuery Mobile. However if one does not use jquery.mobile.css, which are needed in HTML at the top of the page?
If one uses ThemeRoller, jquery.mobile.theme.css becomes MySITE.css (whatever name was selected during the export process in ThemeRoller). If one uses a custom theme, then that theme css is needed, along with jquery.mobile.structure.css.
If one includes jquery.mobile.icons.css, does that in turn include in the external-png, external-svg, and inline-png files?
And what is "jquery.mobile-1.4.5.min.map" for and when is it needed?
That would all be good information for the documentation in stackoverflow.
I created a custom theme (mysite.css) in ThemeRoller so I include the following in HTML (in the appropriate link of script tag):
mysite.css
jquery.mobile.icons-1.4.5.css
jquery.mobile.structure-1.4.5.css
jquery-2.2.4.min.js
jquery.mobile-1.4.5.js
Is that correct?
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.
I want to use just the slide transitions / AJAX navigation component of jQuery Mobile. On jQuery Mobile's website they have a "Custom Builder Tool" which lets you select just the "AJAX Navigation System" (and it auto-selects associated stuff like transitions).
http://jquerymobile.com/download-builder/
This yields some custom JavaScript and CSS files. For the life of me, I can't get this to work on a webpage. If I include these custom files, then add data-transition="slide" to an anchor element, nothing happens. If I include the full jQuery Mobile library it works perfectly (but screws up the styling of my mobile site). How can I make this work? Maybe one needs to initialize the custom jQuery Mobile manually? I can't find anything in the docs about this. Help!
Here's how I got this to work:
I included the latest jQuery Mobile js but used the stripped down css from my custom JQM build (using the Custom Builder tool).
data-role="page" was added to page content containers. Some scripts called in needed to be moved to now load from within the content containers. Now transitions work as expected.
I hope this helps somebody.
What is the purpose of the div 'data-role' option seen in the TriggerIO template files? Am I to assume that I can ignore this and build my app as if I would build a normal website in HTML5? Or do I need to use different tag options in order to initiate CSS selectors and such? There doesn't seem to be much information about the real differences between your TriggerIO apps and how you would write a normal HTML5 app.
I'm creating a children's story app whereby you can view an image and some text, and swipe for the next page). Should I be using canvas to load the images and text or is it best to use the older school img tags and other markup?
The example app that you get when you create a new app using the TriggerToolkit uses jQuery mobile. The data-role attributes are used by jQuery mobile:
In the body, a div with a data-role of page is the wrapper used to delineate a page, and the header bar (data-role="header") and content region (data-role="content") are added inside to create a basic page (these are both optional). These data- attributes are HTML5 attributes used throughout jQuery Mobile to transform basic markup into an enhanced and styled widget.
From: http://jquerymobile.com/demos/1.2.0/docs/about/getting-started.html
You can delete all this and use whatever markup, stylesheets and JavaScript you would usually when making a website. I'd definitely recommend using <img> and regular text rather than doing everything in a <canvas>. My advice would be to "try it and see", treating the development as you would a mobile website, but with assets stored locally and the ability to leverage forge APIs.
a Project I am currently working on uses the jQuery UI framework for some of its widgets.
To provide the user with a global look and feel I would like to use the framework also for its css stuff.
I am implementing at the moment a dashboard like homepage, where the user can see an overall status of its data. This dashboard is build of some divs that should be aligned into a grid layout.
I try to style the divs like follows
<div class="ui-widget">
<div class="ui-widget-header">Box Header</div>
<div class="ui-widget-content">
Content of the Box
</div>
</div>
Later I would like to implement some draggable-and-sortable functionality.
The Problem I am facing right now is that the boxes aren't properly aligned.
Does anyone has a hint on using jQuery.UI for that kind of css work?
I was studing the CSS framework documentation on jqueryui.com but there aren't that much information.
best regards,
Gordon
I tried your example and it works. I didn't see anything wrong... Which browser are you using? if you are using IE by any chance that could be the problem. Even though it is suppose to be cross-browser... I do not use IE so I can't check that, sorry. Try it with any other browser and see if that is fixed. Also be sure you are including the ui-core and the ui-theme files. Do not include any other CSS file and see if that is fixed. I recommend you to use firebug (in firefox) to see how the styles are applied.
Check how the CSS is applied in this page. You may find it useful.
Can you provide an example where it doesn't work for you?
Maybe you load your own css after you load the jQuery-UI-css and overwrite something.
If your content box and header box don't align, it is probably due to different padding in the css, try setting your content box padding to the same as your heading box padding. This fixed the issue when I came across it.
