+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|
