A simple [Material Design](https://www.google.com/design/spec/material-design/introduction.html) gauge control implemented in pure CSS/HTML. Includes a JavaScript implementation to change the gauge value dynamically.
|
||||
|
||||
Origin: https://github.com/sathomas/material-gauge
|
||||
|
||||
|
||||
|
||||
Check out the [live example](http://sathomas.me/material-gauge/).
|
||||
|
||||
The basic markup for the gauge is as follows:
|
||||
|
||||
```
|
||||
<div class="gauge" id="myGauge">
|
||||
<div class="gauge__container">
|
||||
<div class="gauge__marker"></div>
|
||||
<div class="gauge__background"></div>
|
||||
<div class="gauge__center"></div>
|
||||
<div class="gauge__data"></div>
|
||||
<div class="gauge__needle"></div>
|
||||
</div>
|
||||
<div class="gauge__labels mdl-typography__headline">
|
||||
<span class="gauge__label--low">No</span>
|
||||
<span class="gauge__label--spacer"></span>
|
||||
<span class="gauge__label--high">Yes</span>
|
||||
</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
The gauge value is specified by `transform:` property on both the `.gauge__data` and `.gauge__needle` elements. The value for the rotation is
|
||||
`0.5 × X - 0.5` turns, where `X` ranges from 0 (left-most position) to 1 (right-most position). For example, to set the gauge at "3/4 full", you can specify the `transform` as
|
||||
|
||||
```
|
||||
.gauge__data {
|
||||
-webkit-transform: rotate(-0.125turn);
|
||||
-moz-transform: rotate(-0.125turn);
|
||||
-ms-transform: rotate(-0.125turn);
|
||||
-o-transform: rotate(-0.125turn);
|
||||
transform: rotate(-0.125turn);
|
||||
}
|
||||
.gauge__needle {
|
||||
-webkit-transform: rotate(-0.125turn);
|
||||
-moz-transform: rotate(-0.125turn);
|
||||
-ms-transform: rotate(-0.125turn);
|
||||
-o-transform: rotate(-0.125turn);
|
||||
transform: rotate(-0.125turn);
|
||||
}
|
||||
```
|
||||
|
||||
As the example indicates, you probably want to use vendor prefixes for maximum compatibility.
|
||||
|
||||
If you wish, you can use the included JavaScript component to set and update the gauge value. The component API is quite simple. First, create a new object:
|
||||
|
||||
var gauge = new Gauge();
|
||||
|
||||
You can optionally pass a DOM element (constructed as above) to the constructor:
|
||||
|
||||
var gauge = new Gauge(document.getElementById("myGauge"));
|
||||
|
||||
If you don't pass the DOM element as a constructor parameter, you can initialize it later using the `element()` method:
|
||||
|
||||
gauge.element(document.getElementById("myGauge"));
|
||||
|
||||
> Note that the component will not construct the DOM element itself. You must supply a pre-constructed element with the sub-elements indicated above.
|
||||
|
||||
Once you have an initialized constructor, set the value (between 0 and 1) using the `value()` method:
|
||||
|
||||
gauge.value(0.75);
|
||||
|
||||
As a final enhancement, if you're going to update the gauge live on the page, you can add the `gauge--liveupdate` class to the parent element. This will enable a nice CSS-based animation for value updates.
