jquerymobile loading message theme

Question

I have a question about the loading message on jQuery Mobile.

By default, the loading message theme is a, according to jQuery Mobile code:

<div class="ui-loader ui-body-a ui-corner-all" style="top: 204.5px; ">...</div>

I would like to know how I can change the default theme of this div, I can't figure it out.

Thanks in advance.

Answer 1

I have very successful solution for this ...

you just go to your jquery-mobile.js. you have to take these steps here

1. find " defaultHtml:"< div class='"+b+"' >< span class='ui-icon-loading' >< /span >< h1 >< /h1 >< /div >"
2. replace it with
   "defaultHtml:"//< div class='"+b+"' >//< span class='ui-icon-loading' >//< /span >< h1 >< /h1 >< /div >"

Best of Luck

• please remove all spaces ...

Answer for old version, see below for jQuery Mobile 1.1.0+

I'm not aware of a variable you can set in the mobileinit event handler but you can change the theme'd class when the document is ready:

//run the code on `document.ready`
jQuery(function ($) {

    //find the loader div and change its theme from `a` to `e`
    $('.ui-loader').removeClass('ui-body-a').addClass('ui-body-e');
});

Here is a jsfiddle of the above solution (you can change the theme for the loading dialog from a list of buttons): http://jsfiddle.net/jasper/eqxN9/1/

Update

jQuery Mobile 1.1.0 adds some support for this, you can set some defaults:

loadingMessage string, default: "loading" Set the text that appears when a page is loading. If set to false, the message will not appear at all.

loadingMessageTextVisible boolean, default: false Whether the text should be visible when a loading message is shown. The text is always visible for loading errors.

loadingMessageTheme string, default: "a" The theme that the loading message box uses when text is visible.

Source: http://jquerymobile.com/demos/1.1.0/docs/api/globalconfig.html

Note that you must set loadingMessageTextVisible to true for the loader theme override to work because of the new loader design. If you don't set a message then there is no background to change the color-of...

Here is a demonstration: http://jsfiddle.net/vHJnd/

A quick peruse through the documentation shows that you can do this on the fly as well now:

$.mobile.showPageLoadingMsg("a", 'loading message');

You can add these arguments to the showPageLoadingMsg() function to force a theme and message to display. This is an alternative to setting a default value.

In jQuery Mobile 1.1, the loader is now themeable. A demo/test page is here: http://jquerymobile.com/demos/1.1.0-rc.1/docs/config/loadingMessageTextVisible.html

Answer 4

The js fiddle listed (http://jsfiddle.net/N7Z9e/95/) is a good starting point. I'm building on to this a little bit. I find you sometimes have to use !important to override the base styles. I hate using it but no other good way to get around it at times.

    /* override loader */
    div.ui-loader.ui-body-a {
    border: 3px solid #104070  /*{a-body-border}*/;
    background-color: rgba(0, 62, 87, .9); color: rgba(0, 62, 87, .9);
    background-image: none;
    font-weight: normal;
    }

/* Control the text placement, font size, etc..*/    
    div.ui-loader h1 { margin-top:10px; margin-bottom:4px; color:#fff !important;}


    /* Change The Spinner Image And Styles *
    .spinner{

    }

Important Note: In a future version of JQM the loader will be easier to control the message in the loader. You can see some improvements by via the git hub.

Answer 5

It looks the loading message isn't themable.

When you look in the source code you will see:

// loading div which appears during Ajax requests
// will not appear if $.mobile.loadingMessage is false
var $loader = $( "<div class='ui-loader ui-body-a ui-corner-all'><span class='ui-icon ui-icon-loading spin'></span><h1></h1></div>" );

This means that it picks always ui-body-a

Probably the safest way is to override div.ui-loader.ui-body-a, see http://jsfiddle.net/N7Z9e/95/

Answer 6

Well I would suggest the jQM ThemeRoller Tool they released:

• http://jquerymobile.com/themeroller/

but if you wanted to play around with it, here you go:

JS

$('.changeLoadingBackgroundColor').click(function() {
    $.mobile.showPageLoadingMsg();
    var bgColor = $(this).attr('id');
    var loader  = $('div.ui-loader');

    loader.removeAttr('class');
    loader.attr('class','ui-loader ui-body-'+bgColor+' ui-corner-all');
    $(this).trigger('create');
});

HTML

<div id="test" data-role="page">
    <div data-role="content">
        Change the Background Color of the Loading Message, Choose a <b>Theme</b>
        <div data-role="controlgroup" data-type="horizontal">
            <input type="button" id="a" class="changeLoadingBackgroundColor" value="A"/>
            <input type="button" id="b" class="changeLoadingBackgroundColor" value="B"/>
            <input type="button" id="c" class="changeLoadingBackgroundColor" value="C"/>
            <input type="button" id="d" class="changeLoadingBackgroundColor" value="D"/>
            <input type="button" id="e" class="changeLoadingBackgroundColor" value="E"/>
            <input type="button" id="custom-color" class="changeLoadingBackgroundColor" value="Custom Color"/>
        </div>
    </div>
</div>
