Rader - range slider.


How to use rader

Make sure you have jQuery on your page.

Pick some js

<script src="rader.min.js"></script>

Then add some html and css

<div class="rader">
    <div class="rader__track">
        <!-- Runners -->
        <div class="rader__runner _left"></div>
        <div class="rader__runner _right"></div>

<script src="rader.css"></script>

or make your own. If so, make sure you have a proper css.

Then just call rader:

    runners: '.rader__runner'

Thats it!

For advanced usage see API below.


  • 2, 3, 4... 10000000 runners per one slider
  • Bumping, sticking, transitioning...
  • Non-linear and exponent intervals support
  • Flexible markup support
  • (new!) 1 runner support
  • (new!) Vertical mode


Attention! the context for all input selectors is document, not 'root' param! Remember that and precisely define selectors for all your dom-elements.

Document is chosed as default context because in that case you have more power: you may, for example, define one track inside root and two additional tracks outside root dom-element.

Also, you can pass jQuery-objects instead if selectors, like $('.track') instead of '.track'.

    // Root dom node (most parent) for slider, also - statical part of track
    root: '.slider',

    // Whole track.
    track: '.track',

    // Active (between runners) part of track
    trackActive: '.track-active',

    // Dom elements of points
    points: '.point',

    // Dom elements responsible for dragging (runners)
    runners: '.runner',

    // CSS modifier for points in range for now
    pointInRangeCls: '.point_active'

    // Relative linear point positions
    pointsPos: [ 0, 12, 33 ],

    // Values which will be linked to points
    values: [1, 10, 77, 10000],

    // Values on which runners will point on slider init
    runnersVal: [ 2, 600 ],

    // Runners with 1 will be freezed (user will not be able to move them)
    runnersFreeze: [ 1, 0 ],

    // Sticky radius for runner (around each point) in px
    stickingRadius: 40,

    // Minimal distance between two runners in px
    bumpRadius: 22,

    // Use 'log' value if you want logarithmic scale
    scale: 'log',

    // Which direction will be used (horizontal '-' by default or vertical '|') for slider
    direction: '-',

    // If true, click to track will move the closest non-freezed runner to click point
    click: false,

    // CSS class on root element when dragged runners goes to stick (with transition) on point
    transCls: '.rader_trans',

    // Event on drag end (mouseup, touchend, generating only by real user)
    change: function(e) {},

    // Event on drag (mousemove, touchmove)
    move: function(e) {},

    // Event on drag end (generating by real user or by methods like setters .pos and .val)
    onUpdate: function(e) {}


var rader = $('.rader').rader(params);

 * Emulation of drag of runner number num (0, 1, 2...) to defined position pos (px)
 * @return current position (px) of runner number num (0, 1, 2...) in getter mode, and rader instance in setter mode
rader.pos(num, pos);

 * Emulation of drag of runner number num (0, 1, 2...) to defined position of value val (user-defined dimension)
 * @return current value (user-defined dimension) of runner number num (0, 1, 2...) in getter mode, and rader instance in setter mode
rader.val(num, val);

 * Invalidating all positions of runners and track

 * Killing the rader instance, all its event listeners
