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

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 {

height: 40px;

margin: auto;

margin-top: 20px;
