此插件能干什么？
一句话概括：通过程序主动触发移动端滑动、拖拽、触碰等操作
插件有什么用呢？
可以用于爬虫，也可以用于自动化测试以及程序演示
插件演示地址 （从网上扒了一个canvas绘图的demo，引入touchRobot,通过程序绘图）
注意，请在手机模式查看所有演示地址，插件仅支持移动端
拿常见的滑动相关demo举例,程序触发动端滑动
jQuery-slide滑块验证码
操作步骤
step1
将代码在控制台粘贴执行
step2
var robot = new touchRobot(document.querySelector('#btn'));
robot.touchTo(0,0,400,0);
swiper轮播
操作步骤
step1
将代码在控制台粘贴执行
step2
var robot = new touchRobot(document.querySelector('.swiper-container'))
robot.touchLeft()
如何使用？
插件支持脚本嵌入，也支持npm安装

将以上代码放入你的网页中即可
npm方式安装
npm install touch-robot
在代码中引入插件
import touchRobot from 'touch-robot'
使用
var robot = new touchRobot(dom);
robot.touchLeft();
插件API
|方法（method）|描述（description）
----|:---😐----:
touchLeft|左滑
touchRight|右滑
touchTop|上滑
touchBottom|下滑
touchTo|定点滑动，参数startX,startY,endX,endY
touchClick|触碰点击
touch|按照给定路径坐标滑动，参数['x1 y1', 'x2 y2', 'x3 y3']
上面介绍了使用方式和API，下面介绍一下实现方式
先卖个关子，你知道有几种方式可以通过程序触发下面button的click事件吗？
<button id="main">按钮</button>
var btn = document.getElementById('main');
btn.addEventListener('click', function(){
alert('click me')
}, false);
btn.addEventListener('touchstart', function(){
alert('touch me')
}, false);
估计多数想到的是这样触发
document.getElementById('main').click()
那你还知道其它方式触发button的click事件吗？
what?
var event = document.createEvent('Event');
event.initEvent('click', true, true);
btn.dispatchEvent(event);
上面这种方式同样可以触发click
touch事件怎么主动触发呢？
touch事件比较复杂，不能像click那种直接触发，实现方式相对曲折一点
var x = 100;
var y = 200;
var touch = new Touch({
identifier: Date.now(),
target: this.touchEle,
clientX: x,
clientY: y,
pageY: y,
pageX: x,
radiusX: 2.5,
radiusY: 2.5,
rotationAngle: 10,
force: 0.5
});
// 构建TouchEvent
var touchEvent = new TouchEvent('touchstart', {
cancelable: true,
bubbles: true,
touches: [touch],
targetTouches: [touch],
changedTouches: [touch]
});
btn.dispatchEvent(touchEvent);
