MediaQueryObserver 对象,用于监听页面 media query 状态的变化,如界面的长宽是不是在某个指定的范围内。
### uni.createMediaQueryObserver([this])
创建并返回一个 ``MediaQueryObserver`` 对象实例。
**this说明:**
自定义组件实例。**支付宝小程序不支持此参数,传入仅为抹平写法差异**
### MediaQueryObserver 对象的方法列表
|方法|说明|
|:-|:-|
|MediaQueryObserver.observe(Object descriptor, function callback)|开始监听页面 media query 变化情况|
|MediaQueryObserver.disconnect()|停止监听,回调函数将不再触发|
**observe 回调函数包含一个参数**
||类型|说明|
|:-|:-|:-|
|intersectionRatio|boolean|页面的当前状态是否满足所指定的 media query|
### 代码示例
