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">
