# mouse-event
|
||
|
|
Provides a normalized, cross-browser, garbage-collection-free API for reading out the state of a mouse event.
|
||
|
|
|
||
|
|
### Why is this needed?
|
||
|
|
Because it is 2015 and somehow every major browser still disagrees on even the most basic details of MouseEvents. Seriously guys.
|
||
|
|
|
||
|
|
# Example
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var mouse = require('mouse-event')
|
||
|
|
|
||
|
|
window.addEventListener('mousemove', function(ev) {
|
||
|
|
document.body.innerHTML =
|
||
|
|
'<p>Buttons: ' + mouse.buttons(ev) +
|
||
|
|
' x:' + mouse.x(ev) +
|
||
|
|
' y:' + mouse.y(ev) + '</p>'
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|

|
|
#### `mouse.buttons(event)`
|
||
|
|
Returns a bit vector, similar to `event.which` in WebKit encoding the state of the mouse buttons.
|
||
|
|
|
||
|
|
* `event` is a mouse event
|
||
|
|
|
||

* `1` - left mouse
|
||
|
|
* `2` - right mouse
|
||
|
|
* `4` - middle mouse

* `1<<k` - button k+1
|
||
|
|
|
||
|
|
#### `mouse.x(event)`
|
||
|
|
Returns the relative x-coordinate of the mouse event
|
||
|
|
|
||
|
|
* `event` is a mouse event
|
||
|
|
|
||
|
|
**Returns** The relative x-coordinate of `event`, similar to `event.x` in WebKit
|
||
|
|
|
||
|
|
#### `mouse.y(event)`
|
||
|
|
Returns the relative y-coordinate of the mouse event
|
||
|
|
|
||
|
|
* `event` is a mouse event
|
||
|
|
|
||
|
|
**Returns** The relative y-coordinate of `event`, similar to `event.y` in WebKit
|
||
|
|
|
||
|
|
#### `mouse.element(event)`
|
||
|
|
Get the element which triggered the event.
|
||
|
|
|
||
|
|
* `event` is a mouse event
|
||
|
|
|
||
|
|
**Returns** The `target` or `srcElement` or whatever it was that triggered the event
