How to create an on/off switch with Javascript/CSS?

Question

I want to have a sliding switch. On the left would be Off and on the right would be On. When the user toggles the switch, I want the \'slider\' portion to slide to the other

Answer 1

You can take a look at Shield UI's Switch widget. It is as easy to use as this:

<input id="switch3" type="checkbox" value="" />

<script type="text/javascript">
    jQuery(function ($) {
        $("#switch3").shieldSwitch({
        onText: "Yes, save it",
        ffText: "No, delete it",
        cls: "large"
    });
</script>

Answer 2

You can achieve this using HTML and CSS and convert a checkbox into a HTML Switch.

HTML

      <div class="switch">
        <input id="cmn-toggle-1" class="cmn-toggle cmn-toggle-round"  type="checkbox">
        <label for="cmn-toggle-1"></label>
      </div>

CSS

input.cmn-toggle-round + label {
  padding: 2px;
  width: 100px;
  height: 30px;
  background-color: #ffffdffffd;
  -webkit-border-radius: 30px;
  -moz-border-radius: 30px;
  -ms-border-radius: 30px;
  -o-border-radius: 30px;
  border-radius: 30px;
}
input.cmn-toggle-round + label:before, input.cmn-toggle-round + label:after {
  display: block;
  position: absolute;
  top: 1px;
  left: 1px;
  bottom: 1px;
  content: "";
}
input.cmn-toggle-round + label:before {
  right: 1px;
  background-color: #f1f1f1;
  -webkit-border-radius: 30px;
  -moz-border-radius: 30px;
  -ms-border-radius: 30px;
  -o-border-radius: 30px;
  border-radius: 30px;
  -webkit-transition: background 0.4s;
  -moz-transition: background 0.4s;
  -o-transition: background 0.4s;
  transition: background 0.4s;
}
input.cmn-toggle-round + label:after {
  width: 40px;
  background-color: #fff;
  -webkit-border-radius: 100%;
  -moz-border-radius: 100%;
  -ms-border-radius: 100%;
  -o-border-radius: 100%;
  border-radius: 100%;
  -webkit-box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
  -moz-box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
  box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
  -webkit-transition: margin 0.4s;
  -moz-transition: margin 0.4s;
  -o-transition: margin 0.4s;
  transition: margin 0.4s;
}
input.cmn-toggle-round:checked + label:before {
  background-color: #8ce196;
}
input.cmn-toggle-round:checked + label:after {
  margin-left: 60px;
}

.cmn-toggle {
  position: absolute;
  margin-left: -9999px;
  visibility: hidden;
}
.cmn-toggle + label {
  display: block;
  position: relative;
  cursor: pointer;
  outline: none;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

Initial answer from 2013

If you don't mind something related to Bootstrap, an excellent (unofficial) Bootstrap Switch is available.

It uses radio types or checkboxes as switches. A type attribute has been added since V.1.8.

Source code is available on Github.

Note from 2018

I would not recommend to use those kind of old Switch buttons now, as they always seemed to suffer of usability issues as pointed by many people.

Please consider having a look at modern Switches like those.

you can get various different style outcomes and its css only - no javascript!

Answer 5

Outline: Create two elements: a slider/switch and a trough as a parent of the slider. To toggle the state, switch the slider element between an "on" and an "off" class. In the style for one class, set "left" to 0 and leave "right" the default; for the other class, do the opposite:

<style type="text/css">
.toggleSwitch {
    width: ...;
    height: ...;
    /* add other styling as appropriate to position element */
    position: relative;
}
.slider {
    background-image: url(...);
    position: absolute;
    width: ...;
    height: ...;
}
.slider.on {
    right: 0;
}
.slider.off {
    left: 0;
}
</style>
<script type="text/javascript">
function replaceClass(elt, oldClass, newClass) {
    var oldRE = RegExp('\\b'+oldClass+'\\b');
    elt.className = elt.className.replace(oldRE, newClass);
}
function toggle(elt, on, off) {
    var onRE = RegExp('\\b'+on+'\\b');
    if (onRE.test(elt.className)) {
        elt.className = elt.className.replace(onRE, off);
    } else {
        replaceClass(elt, off, on);
    }
}
</script>
...
<div class="toggleSwitch" onclick="toggle(this.firstChild, 'on', 'off');"><div class="slider off" /></div>

Alternatively, just set the background image for the "on" and "off" states, which is a much easier approach than mucking about with positioning.

Using plain javascript

<html>

  <head>

     <!-- define on/off styles -->
     <style type="text/css">
      .on  { background:blue; }
      .off { background:red; }
     </style>

     <!-- define the toggle function -->
     <script language="javascript">
        function toggleState(item){
           if(item.className == "on") {
              item.className="off";
           } else {
              item.className="on";
           }
        }
     </script>
  </head>

  <body>
     <!-- call 'toggleState' whenever clicked -->
     <input type="button" id="btn" value="button" 
        class="off" onclick="toggleState(this)" />
  </body>

</html>

Using jQuery

If you use jQuery, you can do it using the toggle function, or using the toggleClass function inside click event handler, like this:

$(document).ready(function(){
    $('a#myButton').click(function(){
        $(this).toggleClass("btnClicked");
    });
});

Using jQuery UI effects, you can animate transitions: http://jqueryui.com/demos/toggleClass/
