项目终于如约上线,但是在春节前又有一个新的活动要做,类似微信的摇一摇活动。也一直在做微信公众号的东西,但是要调用微信摇一摇的接口还是有些困难,因为只提供了摇一摇周边,附近的人以及一系列的红包页面,相对于我们的需求只需要摇一摇这个动作却是大相径庭。
其实h5+javascript写出来的页面,通过获取手机的屏幕长和宽,以及添加声音等就可以实现摇一摇的效果。
第一步,实现手机摇动改变颜色
<!doctype html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width,initial-scale=1.0"/> <title>html5 手机摇一摇</title> <script type="text/javascript"> var color = new array('#fff', '#ff0', '#f00', '#000', '#00f', '#0ff'); if(window.devicemotionevent) { var speed = 25; var x = y = z = lastx = lasty = lastz = 0; window.addeventlistener('devicemotion', function(){ var acceleration =event.accelerationincludinggravity; x = acceleration.x; y = acceleration.y; if(math.abs(x-lastx) > speed || math.abs(y-lasty) > speed) { document.body.style.backgroundcolor = color[math.round(math.random()*10)%6]; } lastx = x; lasty = y; }, false); } </script> </head> <body> 手机摇一摇,改变屏幕颜色。 </body> </html>
主要是手机的devicemotionevent事件
第二步,微信摇一摇手势
相对于第一步就是增加了摇一摇手势,改变了摇动事件。在摇一摇动作之后再添加自己想要的方法即可,无论是想要进入下一个自己做的页面还是触发一个controller事件都可以。

有时候真的可以换一种方法去实现自己想要的功能。附图:demo本来实现的效果是:
