===Jquery-Mobile questions===
====don't even try to re-style JQM====
I think that any native app using JQM probably shouldn't be using listviews. Not in production. Just make your own list. You can use <ul> and <li> or you can just use <div>s. Add your own CSS to format it the way you want. Add fast clicks using delegation from a script loaded from a common <head>. Add whatever hover/selected effect you might like when people click on items.

You will be amazed at how fast a list can be. Just don't use a listview.

P.S. If the only thing in a content block is a list, then omit the data-role="content" as well. Then, you won't have to fight with the default CSS for content.
====Overriding jQuery mobile default styles.====

Since jQuery Mobile applies its classes just before the pageshow event, which always overrides stylesheets specified in the header, the obvious solution would be to whack jQM over the head with its own weapons.

By which I mean the pageshow event, which follows after all styling is done. Since you (apparently, and rightfully) want to override css on all pages, the obvious approach is the following.

I've used this successfully for page headers, which have a ridiculously small area for the page title, causing it to go into ellipsis after nine or ten characters. The cause is the left and right margins of anything that jQM decides to style as the page header title: those are set at 90px, where 40px is fine if you don't include buttons or other stuff in the header.

 $('div[data-role="page"]').live('pageshow',function(event){
      $('div[data-role="header"]').css({ 
            margin-left: 40px;
      })
 })

Margin-left is obviously just an example.

My only reservation is performance. I don't know how bad it is to bind a separate event to all pages for this one purpose.

====Clear the application cache in chrome?====
But watchout, developer tolls doesn't update.
=====ANS: close the page then goto chrome://appcache-internals/);=====

====Turn Object into Array?====
=====ANS: var arr = jQuery.makeArray(elems);=====

====Sort Array?====
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  document.write(fruits.sort());
=====ANS: fruits.sort();=====

====Refresh on attribute change?====

=====ANS: you could hack the widget css shit as seen in tools-developer-elements=====

====Removing appended html using jQuery?====
=====ANS: jQuery('#main').empty();=====

====In jquery-mobile how do you programmically add page elements that have all the css?====
When this code runs you can see it doesn't render the programmatically added input field as a mobile styled element. I could force it to by adding all the classes that get put in when a page is rendered. Is there an easier way?

====[javascript] [jquery-mobile] Why won't mailto include link parameters?====
When this code runs the alert box comes up with the link that includes &list=groceries and &email=tim@sitebuilt.net. When the mailto: fires and brings up the email window those parameters are missing and I can't figure out why. the length of the string doesn't seem to matter.

====[jqm] How can I grab the searchValue?====
If no items match the searchValue I want to add that searchValue to a list.

My plan is to somehow monitor the when the visible matches goes to 0 then grab the value in the filter box.

Here is my test code (it has all it needs to run) I've got the callback function part wrong.
