本文实例为大家分享了JavaScript实现登录滑块验证的具体代码，供大家参考，具体内容如下

html代码

<div class="login-select"> <div v-show="errselectFlag" id="err-select"></div> <p id="title-p">按住滑块，拖拽验证</p> <div id="left-select"></div> <div id="right-select"> <i id="icon-dui" class="iconfont icon-right"></i> </div></div>

javascript代码

// 滑块验证var oRight = document.getElementById("right-select");var bg = document.getElementById("left-select");var title = document.getElementById("title-p");var i = document.getElementById("icon-dui"); oRight.onmousedown = function (e) { var downX = e.clientX; //按下按钮后与窗口的x轴间距 // 鼠标移动事件 oRight.onmousemove = function (e) { if (e.clientX != 240) { oRight.style.left = 0 + "px"; bg.style.left = 0 + "px"; } var moveX = e.clientX - downX; //滑动的时候距离窗口的x轴的间距 //只有在大于0的时候才拖动,否则会出现反向拖动 if (moveX > 0) { oRight.style.left = moveX + "px"; //滑块与左边的距离 bg.style.width = moveX + "px"; //背景的宽度就是滑块距离左边的位置 if (moveX >= 280 - oRight.offsetWidth) { i.className = "iconfont icon-xingzhuang"; i.style.color = "rgb(86, 192, 15)"; title.innerText = "验证通过"; title.style.color = "#fff"; oRight.onmousemove = null; oRight.onmousedown = null; } } }; };

style代码

注：样式为sass文件

*{margin: 0;padding: 0;box-sizing: border-box;} .login-select { width: 280px; height: 40px; margin: auto; margin-top: 20px; margin-left: 15px; margin-right: 15px; text-align: center; line-height: 40px; background: rgba(134, 134, 131, 0.6); display: flex; position: relative; #err-select { width: 138px; height: 38px; position: absolute; right: -152px; top: 0; color: #fff; font-size: 12px; border-radius: 5px; line-height: 38px; text-align: center; background: rgb(177, 71, 71); } #title-p { text-align: center; line-height: 40px; width: 100%; height: 100%; font-size: 14px; position: absolute; } #left-select { width: 0; height: 100%; transform: translate(0.3s); background: rgb(86, 192, 15); } #right-select { width: 40px; height: 40px; background: #fff; color: #aaaa; text-align: center; line-height: 40px; border: 1px solid #ccc; position: absolute; cursor: move; } }
