js插件实现图片滑动验证码
(编辑:jimmy 日期: 2024/11/20 浏览:3 次 )
图片滑动验证码,逻辑是根据鼠标滑动轨迹,坐标位置,计算拖动速度等等来判断是否人为操作,当然下面的代码只是实现前端部分,只记录了拖动的坐标。
先上代码吧,做个备份记录
jquery.lgymove.js
/** * Created by lgy on 2017/10/21. * 图片验证码 */ (function ($) { $.fn.imgcode = function (options) { //初始化参数 var defaults = { callback:"" //回调函数 }; var opts = $.extend(defaults, options); return this.each(function () { var $this = $(this);//获取当前对象 var html = '<div class="code-k-div">' + '<div class="code_bg"></div>' + '<div class="code-con">' + '<div class="code-img">' + '<div class="code-img-con">' + '<div class="code-mask"><img src="/UploadFiles/2021-04-02/front(1).png">css部分:
.code_bg{ position: fixed; top:0; left: 0; right:0; bottom:0; background-color: rgba(0,0,0,.5); z-index: 99; } .icon-login-bg{ background-image: url(../img/icon/loginicon.png); background-repeat: no-repeat; } .code-con{ position: absolute; top:100px; width: 320px; left: 50%; margin-left: -160px; background-color: #fff; z-index: 100; -moz-user-select: none; -webkit-user-select: none; } .code-img{ margin: 5px 5px; padding: 5px 5px; background-color: #f5f6f7; } .code-img img{ display: block; } .icon-w-25{ display: inline-block; width: 25px; height: 25px; text-indent: -9999px; } .icon-push{ cursor: pointer; background-position: -149px -95px; } .code-push{ height: 25px; } .code-btn{ position: relative; height: 30px; text-align: center; color: #999; margin: 10px 10px; box-sizing: border-box; background-color: #f5f6f7; border-radius: 15px; border: 1px solid #e1e1e1; } .code-btn-m{ position: absolute; width: 40px; height: 40px; border-radius: 50%; background-color: #f5f6f7; border: 1px solid #e1e1e1; z-index: 5; top:-8px; left: 10px; box-shadow: 0 0 3px #ccc; cursor: pointer; background-position: -63px 10px; } .code-btn-img{ background-image:url(../img/icon/codejt.png); background-repeat: no-repeat; } .code-btn-img.active{ background-position: -134px 10px; } .code-btn-img.error{ background-position: 8px 10px; } .code-img-con{ position: relative; } .code-mask{ position: absolute; top:0; left: 0; z-index: 10; } .code-tip{ padding-left: 10px; font-size: 12px; color: #999; } .code-tip-red{ color: red; } .code-tip-green{ color: green; }html部分:
