Menu
I want to change a jquery-mobile buttons color swatch dynamically with javascript, but I can't' find a way (except removing and adding all classes and event handlers, but that's to messy).
Whats the best way to do that?

At least in 1.2.0 (1.2.0-rc1) its as simple as (probably it works in minor versions):
$( "#myButton" ).buttonMarkup({theme: 'd'});
not .button('refresh') needed

Well I did do something like this:
JS (might need minor tweaks to get what you want)
$('input[name=theme-options]').change(function() {
var currentTheme = $('#home').attr('data-theme');
var selectedTheme = $(this).val();
alert('CT '+currentTheme+' ST '+selectedTheme);
$('.ui-body-' + currentTheme).each(function(){
$(this).removeClass('ui-body-' + currentTheme).addClass('ui-body-' + selectedTheme);
});
$('.ui-btn-up-' + currentTheme).each(function(){
$(this).removeClass('ui-btn-up-' + currentTheme).addClass('ui-btn-up-' + selectedTheme);
});
$('.ui-btn-down-' + currentTheme).each(function(){
$(this).removeClass('ui-btn-down-' + currentTheme).addClass('ui-btn-down-' + selectedTheme);
});
$('#home').find('*[data-theme]').each(function(index){
$(this).attr('data-theme',selectedTheme);
});
$('#home').attr('data-theme', selectedTheme).removeClass('ui-body-' + currentTheme).addClass('ui-body-' + selectedTheme).trigger('create');
});
HTML (might need minor tweaks to get what you want)

What worked for me is:
//set button active
$(this).parent().addClass('ui-btn-active');
//set button inactive
$(this).parent().removeClass('ui-btn-active');
Adding the class 'ui-btn-active' to the parent will set the current button to active and change the data-theme to 'b'. This will not work for any arbitrary swatch though. So you may still need one of the longer solutions mentioned earlier.

Yes, looks like there is no way to simply change the theme swatch.
I hacked a simple function to exchange the color by regex:
$.fn.changeColorSwatch = function(theme, type) {
if (!type) {
type = 'theme';
}
var currentTheme = this.attr('data-' + type);
if (!currentTheme) {
currentTheme = 'c';
}
this.attr('data-' + type, theme);
var regex = new RegExp('^ui-(.*)-' + currentTheme + '$');
var classes = $.extend({}, this[0].classList);
var i = classes.length;
while (i--) {
var match = classes[i].match(regex);
if (match) {
this.removeClass(match[0]);
this.addClass('ui-' + match[1] + '-' + theme);
}
}
};
I know, it should use jqmData instead of attr, but the data-theme attribute wasn't changed properly.
