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;
}
}
};
};
