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?

I use this and it works perfectly !! :D

Mikael Kindborg answer from Change data-theme in jQuery mobile

$.mobile.changeGlobalTheme = function(theme)
    {
        // These themes will be cleared, add more
        // swatch letters as needed.
        var themes = " a b c d e";

        // Updates the theme for all elements that match the
        // CSS selector with the specified theme class.
        function setTheme(cssSelector, themeClass, theme)
        {
            $(cssSelector)
                    .removeClass(themes.split(" ").join(" " + themeClass + "-"))
                    .addClass(themeClass + "-" + theme)
                    .attr("data-theme", theme);
        }

        // Add more selectors/theme classes as needed.
        setTheme(".ui-mobile-viewport", "ui-overlay", theme);
        setTheme("[data-role='page']", "ui-page-theme", theme);
        setTheme("[data-role='header']", "ui-bar", theme);
        setTheme("[data-role='listview'] > li", "ui-bar", theme);
        setTheme(".ui-btn", "ui-btn-up", theme);
        setTheme(".ui-btn", "ui-btn-hover", theme);
    };

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)

<div data-role="page" id="home" data-theme="a"> 
    <div data-role="content">
        <div class="content-primary">

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

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.

Buttons need to have the parent element theme changed as well.

Add the following code to the end of the $.fn.changeColorSwatch function

      if(this.attr('type') == 'button'){
      this.parent().changeColorSwatch(theme, type);
  }

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.
