Question

I have made a web app using jQuery Mobile, jQuery and html. It is basically an rss reader for its site.

$(document).ready(function() {
$('[data-role=button]').click(function() {
    var $id = $(this).attr('id');
    switch($id)
    {
        case 'news-button':
        var type = 'news';
        var url = '/tag/news/';
        break;
        //etc...
    }
    $.get('http://wiiuandmii.com' + url + 'feed/', function(data) {
        $('#' + type + '-content').empty();
        var i = 0;
        $(data).find('item').each(function() {
            i = i + 1;
            $('#' + type + i).empty().remove();
            var $item = $(this);
            var html = '<li>';
            html += '<a href="#'+ type + i + '">';
            html += $item.find('image').text();
            html += '<h3 style="color: #01acca;">' + $item.find('title').text() + '</h3>';
            html += '<p>' + $item.find('pubDate').text() + '</p>';
            html += '</a>';
            html += '</li>';
            $('#' + type + '-content').append($(html));
            $('#' + type + '-content').find('img.attachment-thumbnail').removeClass().removeAttr('width').removeAttr('height');
            $('#' + type + '-content').listview('refresh');
            var page = '<div data-role="page" id="' + type + i + '" data-url="' + type + i + '">';
            page += '<div data-role="header" data-theme="c" data-position="fixed"><a href="#home" data-rel="back" data-theme="b" data-icon="arrow-l">Back</a><h1 style="margin-top:0px; margin-bottom:0px;"><img src="images/header.png" title="Wii U and Mii" alt="Wii U and Mii"/></h1></div>';
            page += '<div data-role="content" data-theme="c" class="main-' + type + i + '">';
            page += '<h1 style="color: #01acca;">' + $item.find('title').text() + '</h1>';
            page += '<p>' + $item.find('dc:creator').text() + '</p>';
            page += $item.find('desc').text();
            page += '</div>';
            page += '<div data-role="footer" data-theme="c"></div>';
            page += '</div>';
            $('body').append($(page));
            var test = '#' + type + i;
            $(test).page();
        });
    });
});
});

When the button on the home page is clicked it page transitions to the #news page just fine. The problem is, the content section of the #news page remains blank for about 5 seconds as the content is loading. The loading message does not appear. What should happen is the loading message should appear on the #home page whilst all the content is loaded up, and then transition to the #news page after it has been filled.

Am I triggering the loading of the content on the wrong event for the effect I want, if so which event should I be using?

EDIT on 30/9/2011

I have managed to get the page transition to wait until the list has been fully loaded before it transitions, however the loading message still does not appear.

I used:

$('#news').live('pagebeforeshow',function(event){
    $.mobile.showPageLoadingMsg();

instead of document ready and the .click

and I used:

$.ajax({
    url: 'http://wiiuandmii.com' + url + 'feed/',
    async: false,
    success:function(data){

instead of the .get()

A member on the github-jQM forum suggested the following workaround that worked for me. Note, I am using jQM 1.0b1.

$(‘.ui-loader h1’).text(‘my custom loading msg..’);
