DOM element size sensor which will callback when the element size changed.
DOM 元素尺寸监听器,当元素尺寸变化的时候,将会触发回调函数!
- rc-size-sensor: React component wrapper.
npm i --save size-sensor
Then import it.
import { bind, clear } from 'size-sensor';
or import it by script
in HTML, then get sizeSensor
on window.
<script src="https://unpkg.com/size-sensor/dist/size-sensor.min.js"></script>
- bind & unbind
import { bind, clear } from 'size-sensor';
// bind the event on element, will get the `unbind` function
const unbind1 = bind(document.querySelector('.container'), element => {
// do what you want to to.
});
const unbind2 = bind(document.querySelector('.container'), element => {
// do what you want to to.
});
// if you want to cancel bind event.
unbind1();
- clear
import { bind, clear } from 'size-sensor';
/*
* // bind the resize event.
* const unbind1 = bind(...);
* const unbind2 = bind(...);
* ...
*/
// you can cancel all the event of element.
clear(element);
There is only 2 API:
- bind(element, callback)
Bind the resize trigger function on element. The function will return unbind
function.
- clear(element)
Clear all the object and resize event on element.
The size sensor strategies include:
ResizeObserver
: use resizeObserver to observe element's size.object
: use object document's resize event.
If ResizeObserver
exists, use it, else use object
as default.
