Just curious if there are any "best practices" for applying backgrounds to mobile websites. Because a phone (or iPad) can be turned horizontally or vertically, we're kind of stuck on how to best design and/or implement graphics considering the iphone/ipad functionality. Thanks!

Hi terramar,

Do you mean CSS background images? I don't think it matters, since the page will look the same at either orientation - it'll just be wider in landscape. Of course you need to ensure that your text and background images look OK at both sizes.

great tutorial. thanks!

Question: Once you have created your web application using Jquery Mobile, HTML, CSS etc...how do you go about wrapping it into a cross platform App to run on iPhone, Android etc? i mean so it can be distributed in the various appstores and downloaded as an App?

cheers

Hi Kanizares,

Web apps are usually designed to run at least partly on a web server, so they can't easily be converted to cross-platform native mobile apps.

For iOS you may be able to take your (JavaScript-only) web app and wrap it in a webView within an iOS application - here's an example:

You mentioned the following in the JQM post
<div data-role="header">

This lets you create a toolbar at the top of the page, used for things like the page title and buttons. (Typically there is at least a "Back" button which the user can tap to return to the previous page.) By adding data-position="fixed" to the header, you can make sure the header always stays at the top of the screen.

This is my master page template but i don't see a back button when i navigate accross all the pages that use this master page. Please help

<div data-role="page">

<div data-role="header" data-theme="e">
<h1>myCompany</h1>
</div><!-- /header -->

<div data-role="content" data-theme="e">
<p>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">

</asp:ContentPlaceHolder>
</p>
</div><!-- /content -->

<div data-role="footer" data-theme="e">
<h4>View Full Site</h4>
</div><!-- /footer -->
</div><!-- /page -->
</body>
</html>

@techhelp: You won't see a "Back" button on the first-visited page of your JQM site. JQM only adds a "Back" button once the user visits another page within the site.

Hi Matt,

I commend you on this nicely put article, will be depending on it to spawn the first web app. Question though, would you use jQuery(document).ready() function, as you do in the realm of non-mobile web development, for your custom user functions and events trapping like clicks, triggers and so forth?

Thanks
28-Mar-11 02:19
Hi nunu,

jQuery Mobile triggers a 'pageshow' event whenever a mobile page is displayed - this is probably what you want to use. More info:

Hi all,

I have a list view with 48 x 48 pixels icons. Effectively they seem to be displayed as 80 x 80 pixels so the display is not very nice. I tried to create a specific style in my own style sheet but nothing change.

How can I use icon that are not 16 x 16 neither 80 x 80 ?

Thanks
20-Jun-11 06:35
@Quikdav: I would open up the resulting page in Firefox with Firebug or Safari/Chrome and inspect the img element. This will show you all the CSS classes assigned to the icon and its surrounding elements. You could then try creating appropriate CSS selectors to set the width/height.

If all else fails then use an inline style on the img element.

Hi

Great article. I'm using jQuery mobile a the moment for an app.
I have a contact form set up in the app and the 'action' links to a PHP file (email.php) that processes the form. It works fine in webspace, but does not work when in PhoneGap, in the iPhone Simulator. So assuming it won't work on an actual iPhone.

I can only assume I'll need to link the app to a contact form in webspace. Or should I be looking at an Ajax/PHP solution. I see there are Tutorial sites out there showing how to build Ajax contact forms.

Any advice would be appreciated.

What an amazing help!

Question from a newbie:

I'm gonna make a survey for iPad for a customer, and I need some really BIG buttons.

Is there any way to change the size on the buttons? The one on this page looks really good.

Thanks for good work!
15-Aug-11 08:58
how about the coding for ipad?

@Nig567: Yes, you can only run HTML/CSS/JS in the PhoneGap app itself. PHP needs to run on a server.

@farbrorc: Try setting a big font size on .ui-btn-up-c, .ui-btn-hover-c, .ui-btn-down-c etc in the CSS.

Hi all

I can't trigger the event "beforepageshow". I put it into my index.php file but It never fire for any page !!

$(document).bind("mobileinit", function()
{
$('div[data-role="page"]').live('beforepageshow', function(event, ui)
{
alert( "pagebeforeshow" );

});
});

What' wrong with my code ?

I understood "mobileinit" should be be defined one time (in the index.php for example). Not in all the files (= pages) of my web site. Should I define "beforepageshow" event for all my pages into "mobileinit" function ? I would like to define each "beforepageshow" event in the associated page. Is it possible and if yes, how ?

Thanks and regards

Hi Matt,

Is it possible to explain how to run jquery mobile only on mobile devices, and how to show a "regular" site on the screen?

Kind regards,
Koen
18-Nov-11 00:50
@koentimmers: To do that, you'd probably need to resort to user agent detection for common mobile browsers, either on the server (eg PHP) or using JavaScript. You can then serve either the jQuery Mobile-enhanced or desktop version of your site as appropriate.

Hi Matt,
i am new to Jquery mobile,i want to use jquery mobile pages in jsp,can you tell me how to href jsp pages,i done it for html pages but i dont know how to do it for jsp pages linking.waiting for your valuable answer,please post an example if you have in your site.
20-Mar-12 02:35
@venu: Never used JSP, but I know that JSP can serve HTML just like any other server-side language. So just serve your mobile pages - including the jQuery Mobile includes and markup - just like you would any other web page using JSP.

Hi Matt

I have an issue with JQUERY Mobile events.

I have a page 'consommation.php' with a list listview. When I display this page (from index.php containing a listview too), the event 'pagebeforeshow' doesn't occurs. It is the same for the click event when I click on options from 'consommation.php' listview. I don't have any events.

But when I enter directly the URL for 'consommation.php' in my browser (without going through index.php listview), all my events are working !!!

There is something that lock my events !! Any idea on what's wrong ?

Thanks and regards

Here is my code in 'consommation.php' :

<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="css/MyTheme.min.css" type="text/css"/>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.1/jquery.mobile.structure-1.1.1.min.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>

<script>
$('div[id="consommation"]').live("pagebeforeshow", function()
{
alert("pagebeforeshow");
});

$('div[id="consommation"] ul[data-role="listview"] a').live("click", function()
{
alert("click");
var dataurl = $(this).attr("data-url");
alert(dataurl);
if (dataurl != null)
{
$.mobile.changePage("sonde_detail.php" + dataurl);
}
});
</script>

<script src="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.js"></script>
