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

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

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);
```

到这其实我的插件实现的几个核心的点已经介绍完毕了

如果你感兴趣可以去我的github去看touchRobot源码，如对你有帮助也欢迎Star，如有问题也欢迎指出
