本文实例为大家分享了vue实现滑动解锁功能的具体代码,供大家参考,具体内容如下
话不多说,直接上代码;
<template>
<div>
<div id="box">
<div class="bgColor"></div>
<div class="txt">滑动解锁</div>
<!--给i标签添加上相应字体图标的类名即可-->
<div class="slider">
<i v-show="!isSuccess" class="el-icon-d-arrow-right"></i>
<i v-show="isSuccess" class="el-icon-check"></i>
</div>
</div>
</div>
</template>
<script>
export default {
mounted() {
var self = this;
//一、定义了一个获取元素的方法
function getEle(selector) {
return document.querySelector(selector);
}
//二、获取到需要用到的DOM元素
var box = getEle("#box"), //容器
bgColor = getEle(".bgColor"), //背景色
txt = getEle(".txt"), //文本
slider = getEle(".slider"), //滑块
icon = getEle(".slider>i"),
successMoveDistance = box.offsetWidth - slider.offsetWidth, //解锁需要滑动的距离
downX; //用于存放鼠标按下时的位置
//三、给滑块添加鼠标按下事件
slider.onmousedown = mousedownHandler;
slider.ontouchstart = mousedownHandler; //移动端加touchstart事件
//3.1鼠标按下事件的方法实现
function mousedownHandler(e) {
bgColor.style.transition = "";
slider.style.transition = "";
var e = e || window.event || e.which;
downX = e.clientX ? e.clientX : e.changedTouches[0].clientX;
if (!self.isSuccess) {
//在鼠标按下时,分别给鼠标添加移动和松开事件
document.onmousemove = mousemoveHandler;
document.onmouseup = mouseupHandler;
//添加移动端对应事件
document.ontouchmove = mousemoveHandler;
document.ontouchend = mouseupHandler;
}
}
//四、定义一个获取鼠标当前需要移动多少距离的方法
function getOffsetX(offset, min, max) {
if (offset < min) {
offset = min;
} else if (offset > max) {
offset = max;
}
return offset;
}
//3.1.1鼠标移动事件的方法实现
function mousemoveHandler(e) {
var e = e || window.event || e.which;
var moveX = e.clientX ? e.clientX : e.changedTouches[0].clientX;
console.log(moveX);
var offsetX = getOffsetX(moveX - downX, 0, successMoveDistance);
bgColor.style.width = offsetX + "px";
slider.style.left = offsetX + "px";
if (offsetX == successMoveDistance) {
success();
}
//如果不设置滑块滑动时会出现问题(目前还不知道为什么)
e.preventDefault();
}
//3.1.2鼠标松开事件的方法实现
function mouseupHandler(e) {
if (!self.isSuccess) {
bgColor.style.width = 0 + "px";
slider.style.left = 0 + "px";
bgColor.style.transition = "width 0.5s linear";
slider.style.transition = "left 0.5s linear";
}
document.onmousemove = null;
document.onmouseup = null;
//移除移动端事件
document.ontouchmove = null;
document.ontouchend = null;
}
//五、定义一个滑块解锁成功的方法
function success() {
self.isSuccess = true;
txt.innerHTML = "解锁成功";
bgColor.style.backgroundColor = "lightgreen";
//滑动成功时,移除鼠标按下事件和鼠标移动事件
slider.onmousedown = null;
document.onmousemove = null;
//移除移动端事件
document.ontouchstart = null;
document.ontouchmove = null;
}
},
data() {
return {
isSuccess: false,
};
},
};
</script>
