Using jQuery Mobile on a Form Page

In this post I will be marking up a web page that contains a form for use with the jQuery Mobile (JQM) Framework. This post is part of a series of in which I convert a simple site form managing contacts consisting of several XHTML pages to HTML 5 pages which use JQM.

The page I will be using in this demonstration simulates the data entry page for adding a new contact. It contains the usual form controls: text boxes, checkboxes, radio buttons, and a select element. Here is a screen shot of the original (non-JQM) XHTML page in the iPhone 4 Safari browser.

Here is the XHTML markup.

</html>

To add JQM to the page the doctype has been changed to HTML 5 and the JQM CSS and JavaScript files have been added. This has been covered in a previous post. The code above contains some form specific changes. The contents of the form have been wrapped in a div with a data-role of "fieldcontain". This will apply form related changes to the content. Each fieldset has a data-role of "controlgroup". This change is needed to group the contained checkboxes and radio buttons together by specifying that they are in related grouping. For the submit and reset buttons I've added a ui-grid and ui-block classes to the markup that will render the fieldset in a two column layout. The ui-grid defines the wrapped and the ui-block-a and b specify the content of the columns. I've given the buttons themselves explicit data-theme attributes so they will appear visually distinct from one another.

Some form input text box elements have been changed to HTML 5 specific form elements that replace the usual "text" input type. Text boxes that will be used to enter telephone numbers have a type of "tel". Those that are used for an email address have a type of "email" and so forth. Ideally the browser would render a datepicker for "date" inputs, allow only URLs in a "url" input and limit the data entered to the appropriate type. Based on my testing in iPhone and Safari it appears that "tel" will result in numbers keypad rather than the QWERTY keypad being used for data entry, but the other types are not supported.

Using jQuery Mobile Collapsible Sections

In this post I will be adding collapsible sections to a mobile web page using the jQuery Mobile (JQM) framework. This post is part of a series of in which I convert a simple site form managing contacts consisting of several XHTML pages to HTML 5 pages which use JQM.

The page I will be using in this demonstration is the home page for the contacts web site. It displays a list of contacts and links to other pages on the site. Here is a screen shot of the XHTML page in the iPhone 4 Safari browser.

Next is the XHTML for the page.

I have already covered the basic of add the necessary JavaScript, CSS, and HTML 5 markup to a page in order to use JQM. In this post I will focus how I have placed each contact record within a collapsible region. This is accomplished by wrapping each contact record within a div that has a data-role attribute of "collapsible". This replaces the definition list tags (dl, dt, dd) used to markup the XHTML version of the page. Within each div is a h2 heading tag that contains the text that will act as the label for each record. Clicking these labels toggles the show/hide feature of each region. The icons, label, and behavior has automatically been added by jQuery Mobile.

Adding jQuery Mobile to a Web Page

In this post I walk through the changes needed to change a simple mobile web page from an XHTML page to an HTML 5 page that uses jQuery Mobile (JQM). This is the second in a series of blog posts in which I am exploring jQuery Mobile using the Alpha 2 release. This first post in the series can be found at: http://wardlawclaims.blogspot.com/2010/12/introduction-to-jquery-mobile_16.html
The page I will be using in this demonstration is a detail view page for a basic contact management web site. The page is used to display the contact information, phone numbers, email address, etc. for a single contact.

Here is a screen shot of the XHTML page in the iPhone 4 Safari browser.

Next is the XHTML for the detail page before I added jQuery.

Using HTML 5
I started with changing the doctype from the XHTML Basic doctype to the HTML 5 doctype. The jQuery Mobile framework makes use of HTML 5's custom data attributes. These are the attributes "data-*" seen in the markup above and are a feature of HTML 5 intended to allow authors to associate arbitrary data with HTML elements in order to expose that data to custom JavaScript. JQM uses these data attributes to apply styling and behavior to sections of the page. Later in the process when I work on marking up a data entry form I will also be using the new input types introduced in HTML 5.

Adding the jQuery Mobile Resources
In the head element I've added the CSS and JavaScript resources required by the framework. In addition I've referenced an additional custom JavaScript file (custom-mobile-config.js) that contains the settings that I wish to override in the JQM defaults. I plan to cover the contents of this file in a future post.

<!-- CSS and scripts required for jQuery mobile -->
 <link rel="stylesheet" href="jquery.mobile-1.0a2.css" />
 <script type="text/javascript" src="jquery-1.4.4.js"></script>
 <script type="text/javascript" src="custom-mobile-config.js"></script> <!-- this is a custom script file -->
 <script type="text/javascript" src="jquery.mobile-1.0a2.js"></script>

Adding jQuery Mobile to the Markup
The JQM framework includes roles that specify areas of your page as header, content, footer, and navigation. The entire body of the page has been wrapped in a div with the data-role attribute with the value of "page" and a data-theme attribute. The data-role of "page" defines the marked up content as a JQM page and applies CSS. The optional data-theme attribute applies an alternate set of styles. JQM includes some predefined themes. I have not experimented with defining my own theme but I assume that a theme-roller or other customization method does or will exist for creating and modifying themes.

I have wrapped my page heading in a div with a data-role of "header" which I have included a "navbar" in order to create navigation at the top of the page. Navigation items are wrapped in an unordered list and the page's heading is wrapped in an h1 tag.

I have wrapped the rest of the page's markup in a "content" div and it contains the same content as the original XHTML version of the page. JQM takes care of applying the CSS based on the data-role of "content" and the theme that I specified in the "page" div's data-theme attribute. If you inspect the resulting page's DOM with the Chrome browser's development tools you will see that JQM has applied a added an number of styled elements to the basic markup.
