    <p>The JQuery Mobile app I'm working on tends to freak out when the soft keyboard launches. I've implemented a solution and it works great, but I had to edit jquery.mobile-1.2.0.js directly to do it. I'd much rather keep my changes in a jquery.mobile.customizations.js file, which extends jQuery Mobile.</p> <p>I tried to do the following with no success:</p> <pre class="lang-js prettyprint-override"><code>delete $.mobile.getScreenHeight; $.mobile.last_width = null; $.mobile.last_height = null; $.mobile.getScreenHeight = function() { // My modified version } </code></pre> <p>I added alert statements into my <code>$.mobile.getScreenHeight</code>, plus the original <code>$.mobile.getScreenHeight</code>. I did see my custom method's alert being fired, but on occasion, it would fire the alert in the original function as well.</p> <p>Does anyone know the proper way to override a method in $.mobile and also add two new properties?</p> <p>(Full details about the original issue are in <a href="https://stackoverflow.com/questions/12879857/window-resize-due-to-virtual-keyboard-causes-issues-with-jquery-mobile">window.resize due to virtual keyboard causes issues with jquery mobile</a>)</p> <p><strong>Update:</strong></p> <p>@elclanrs - I've tried to implement the code below with no luck. I've also tried swapping the second and third parameters. Whenever I run the code, it fires my extended getScreenHeight, but then it fires the base getScreenHeight. (I hollowed out the original getScreenHeight and put an alert inside. That alert should never fire.</p> <p>Open for thoughts!</p> <pre class="lang-js prettyprint-override"><code>$.mobile = $.extend( {}, $.mobile, { last_width: null, last_height: null, getScreenHeight: function() { // My code... } } ); </code></pre>

    1. COI couldn't find `last_width` and `last_height` by lookin at the source but overriding `getScreenHeight` like that should work...

    2. COYes, sorry - to clarify, I am adding a last_width and last_height property, and I want to override getScreenHeight(). The method I tried, shown above, did not work as expected however. It fired both my custom function and the original function.

    3. COYou don't need to delete it you can just override it. Try overriding with `$.extend` like `$.extend( { getScreenHeight: function() {...} }, $.mobile )`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
