vue实现滑动解锁功能
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> <style> /* 使用全局样式样式去掉 */ * { touch-action: pan-y; } </style> <style> #box { position: relative; width: 300px; height: 40px; margin: 0 auto; margin-top: 10px; background-color: #e8e8e8; box-shadow: 1px 1px 5px rgba(0, 0, 0, 0.2); } .bgColor { position: absolute; left: 0; top: 0; width: 40px; height: 40px; background-color: lightblue; } .txt { position: absolute; width: 100%; height: 40px; line-height: 40px; font-size: 14px; color: #000; text-align: center; } .slider { position: absolute; left: 0; top: 0; width: 50px; height: 40px; /* border: 1px solid #ccc; */ background: #fff; text-align: center; cursor: move; } .slider > i { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); } </style>
