JS 模拟触摸事件

var button = document.getElementsByClassName("geetest_slider_button")[0];
var x = 660;
var y = 469;
var touchs = [];
for(var i =0;i<1000;i++){
touchs.push({
identifier: 0,
target: button,
clientX: i,
clientY: 0,
screenX: i,
screenY:0,
pageY: i,
pageX: 0,
radiusX: 11.5,
radiusY: 11.5,
rotationAngle: 0,
force: 1
})
}
var touch = new Touch({
identifier: Date.now(),
target: button,
clientX: 0,
clientY: 0,
screenX: 0,
screenY:0,
pageY: 0,
pageX: 0,
radiusX: 2.5,
radiusY: 2.5,
rotationAngle: 10,
force: 0.5
})
// 构建TouchEvent
var touchstart = new TouchEvent("touchstart", {
cancelable: true,
bubbles: true,
composed: true,
touches: [touch],
targetTouches: [touch],
changedTouches: [touch]
});
button.dispatchEvent(touchstart);
setTimeout(()=>{
touchs.forEach((v,i)=>{
setTimeout(()=>{
var touch = new Touch(v);
var touchmove = new TouchEvent("touchmove", {
cancelable: true,
bubbles: true,
composed: true,
touches: [touch],
targetTouches: [touch],
changedTouches: [touch]
});
button.dispatchEvent(touchmove);
},i+50);
})
},1000)

记录一下，要求是DOM侦听mousemove事件，PC版chrome需要用手机模式调试
