jquery.themeselect

jQuery theme selection plugin, lets you set up a series of themes, each with one or more CSS files, which are loaded and unloaded when each theme is selected.

It also allows sub themes to automatically be selected based on best colour match using ThemeMatch.

Simple, and more complex usages, are shown below. Both of these are illustrated working in the demo folder.

Synopsis

The simplest usage is like this:

$('select.themeselect').themeselect({
    selected: 'light',
    themes: [
        { name: 'dark',   css: 'simple_dark.css' },
        { name: 'light',  css: 'simple_light.css' },
        { name: 'sunset', css: [ 'simple_sunset.css' ] },
        { name: 'ocean',  css: [
            'content/content_watery.css',
            'sidebar/sidebar_ocean.css',
            'topbar/topbar_ocean.css',
            'theme_ctrlr/ts_green.css',
            ]},
    ],
});

What this does is turn the <select> element into a jquery.themeselect jQuery plugin, which, when it changes, causes the CSS files to be loaded and unloaded. The selected: 'light' parameter causes 'light' to be loaded initially.

Selecting 'sunset' causes 'simple_light.css' to be unloaded and 'simple_sunset.css' to be loaded instead, and then selecting 'ocean' causes 'simple_sunset.css' to be unloaded and 'content/content_watery.css', 'sidebar/sidebar_ocean.css', 'topbar/topbar_ocean.css' and 'theme_ctrlr/ts_green.css' to be loaded.

If (for some odd reason) you have multiple theme selection elements then they need to be kept in sync, one way of doing this is omitting the selected: 'light' parameter and adding this:

$('select.themeselect')
    .on('theme_selection', (jqevent, name) => {
        $('select.themeselect')
            .themeselect('select', name, {no_update:true})
            .themeselect('redraw');
    })
    .first().themeselect('select', 'light');

Advanced usage

It is possible to specify sets of sub themes available for some sub feature that are selected based on colour matching, see ThemeMatch for more explanation but here is an example:

$('select.themeselect').themeselect({
    themes: [
        { name: 'dark',   backgrounds: [ '#000000' ], foregrounds: [ '#ffffff' ] },
        { name: 'light',  backgrounds: [ '#ffffff' ], foregrounds: [ '#000000' ] },
        { name: 'sunset', backgrounds: [ '#bbbb77' ], foregrounds: [ '#990000' ] },
        { name: 'ocean',  backgrounds: [ '#aaffdd' ], foregrounds: [ '#006600' ] },
    ],
    subs: [
        { name: 'sidebar',
            themes: [
                { name: 'sidebar_normal',  css: 'sidebar/sidebar_normal.css',
                        backgrounds: [ '#dddddd' ], foregrounds: [ '#111111' ] },
                { name: 'sidebar_inverse', css: 'sidebar/sidebar_inverse.css',
                        backgrounds: [ '#222222' ], foregrounds: [ '#dddddd' ] },
                { name: 'sidebar_sunset',  css: 'sidebar/sidebar_sunset.css',
                        backgrounds: [ '#eedd88' ], foregrounds: [ '#cc0000' ] },
                { name: 'sidebar_ocean',   css: 'sidebar/sidebar_ocean.css',
                        backgrounds: [ '#aaffdd' ], foregrounds: [ '#006600' ] },
            ] },
        { name: 'topbar',
            themes: [
                { name: 'topbar_normal',  css: 'topbar/topbar_normal.css',
                        backgrounds: [ '#eeeeee' ], foregrounds: [ '#222222' ] },
                { name: 'topbar_inverse', css: 'topbar/topbar_inverse.css',
                        backgrounds: [ '#333333' ], foregrounds: [ '#eeeeee' ] },
                { name: 'topbar_sunset',  css: 'topbar/topbar_sunset.css',
                        backgrounds: [ '#bb8844' ], foregrounds: [ '#990000' ] },
                { name: 'topbar_ocean',   css: 'topbar/topbar_ocean.css',
                        backgrounds: [ '#99ddbb' ], foregrounds: [ '#227722' ] },
            ] },
        { name: 'content',
            themes: [
                { name: 'content_light',  css: 'content/content_light.css',
                        backgrounds: [ '#ffffff' ], foregrounds: [ '#000000' ] },
                { name: 'content_dark',   css: 'content/content_dark.css',
                        backgrounds: [ '#000000' ], foregrounds: [ '#ffffff' ] },
                { name: 'content_muddy',  css: 'content/content_muddy.css',
                        backgrounds: [ '#aa8833' ], foregrounds: [ '#662222' ] },
                { name: 'content_watery', css: 'content/content_watery.css',
                        backgrounds: [ '#aaccdd' ], foregrounds: [ '#005544' ] },
            ],
            subs: [
                { name: 'themeselect',
                    themes: [
                        { name: 'themeselect_red',   css: 'theme_ctrlr/ts_red.css',
                                backgrounds: [ '#807060' ], foregrounds: [ '#ff4444' ] },
                        { name: 'themeselect_green', css: 'theme_ctrlr/ts_green.css',
                                backgrounds: [ '#a0a0c0' ], foregrounds: [ '#117722' ] },
                    ] },
            ] },
    ],
})
.on('theme_selection', (jqevent, name) => {
    $('.themeselect')
        .themeselect('select', name, {no_update:true})
        .themeselect('redraw');
})
.first().themeselect('select', 'light');

In this case the root themes (dark, light, sunset and ocean), which have no CSS files specified, are virtual, and when one of them is selected one theme for each of the sub components (sidebar, topbar, content and themeselect) based on best colour match. Colour matching is done based on the background and foreground meta data above (see ThemeMatch).

Dynamic theme sets

It is not necessary to initialise all the themes at once via parameters to the constructor, if components are dynamically incorporated then they must be added later. For example:

my ts = $('.themeselect');
ts.themeselect();

ts.themeselect('add_theme', {
    name:        'dark',
    backgrounds: [ '#000000' ],
    foregrounds: [ '#ffffff' ],
});
ts.themeselect('add_theme', {
    name:        'light',
    backgrounds: [ '#ffffff' ],
    foregrounds: [ '#000000' ],
});

ts.themeselect('add_sub, {
    name: 'sidebar',
    themes: [
        { name: 'sidebar_normal', css: 'sidebar/sidebar_normal.css',
                backgrounds: [ '#dddddd' ], foregrounds: [ '#111111' ] },
        { name: 'sidebar_inverse', css: 'sidebar/sidebar_inverse.css',
                backgrounds: [ '#222222' ], foregrounds: [ '#dddddd' ] },
        { name: 'sidebar_sunset', css: 'sidebar/sidebar_sunset.css',
                backgrounds: [ '#eedd88' ], foregrounds: [ '#cc0000' ] },
        { name: 'sidebar_ocean', css: 'sidebar/sidebar_ocean.css',
                backgrounds: [ '#aaffdd' ], foregrounds: [ '#006600' ] },
    ]
});

ts.themeselect('redraw');

ES5, ES6 and minification

The dist folder has the following files available:

File	Description
themematch.js	Limited ES6 features (works with Node.js v4+ and most browsers)
themematch_es5.js	ES5 translation (should work with anything)
themematch_es5.min.js	Minified ES5 translation

Build

run npm install to install the dev/build dependencies, and grunt build to build.

This will create ES5 dist/themematch.js and dist/themematch.min.js files, and run the unit tests against them.
