jquery组件,虽然 jquery 语法古老,但是写好了用起来真的很爽啊,本文用滑动人机验证给大家做个详细教程(直接复制代码就可以用噢o(* ̄▽ ̄*)ブ)
第一步 先看下组件本身 component.js
(function() {// 滑动组件 验证人机$.fn.slideComponent = function(o) {// 在这里定义组件的实现逻辑console.log('滑动组件参数 o :', o)let div = ` <div class="container huadong"><canvas width="310" height="155" id="canvas"></canvas><canvas width="310" height="155" id="block"></canvas><div class="refreshIcon"></div><div class="bar"><div id="bar-mask"><div class="verSliderBlock" style="background:https://etfinfo.xcf.cn/appletImg/puzzle-right.png !important;backgroundSize:100% !important"></div></div><span id="slide">向右滑动验证</span></div></div>`layer.open({title: false,btn: '取消',closeBtn: 0,skin: 'diy-huadong-layer',content: div,success: function(layero, index) {$('.diy-huadong-layer').prev().attr("style","z-index: 1989101600 !important;background-color: rgb(0, 0, 0);opacity: 0.3;");},});console.log('滑动开始')var canvas = document.getElementById('canvas');console.log('滑动开始 canvas', canvas)var block = document.getElementById('block');var canvas_ctx = canvas.getContext('2d')var block_ctx = block.getContext('2d')var img = document.createElement('img')var refresh = document.querySelector('.refreshIcon')var x = Math.round(Math.random() * 200) + 10,y = Math.round(Math.random() * 100) + 10,w = 42,l = 42,r = 10,PI = Math.PIconsole.log(x, y)//获取图片后面的随机号码function getRandomNumberByRange(start, end) {return Math.round(Math.random() * (end - start) + start)}//初始化图片function initImg() {img.onload = function() {canvas_ctx.drawImage(img, 0, 0, 310, 155)block_ctx.drawImage(img, 0, 0, 310, 155)var blockWidth = w + r * 2var _y = y - r * 2 + 2 // 滑块实际的y坐标var ImageData = block_ctx.getImageData(x, _y, blockWidth, blockWidth)block.width = blockWidthblock_ctx.putImageData(ImageData, 0, _y)};// 随机滑动验证背景图片var imgIndex = Math.round(Math.random() * 13 + 1)let imgUrl = 'https://etfinfo.xcf.cn/appletImg/' + `puzzle-bg${imgIndex}.png`;console.log('imgUrl:', imgUrl)img.crossOrigin = "Anonymous"img.src = imgUrl// img.src = 'https://picsum.photos/300/150/?image=' + getRandomNumberByRange(0, 100)}//清除tupianfunction clean() {x = Math.round(Math.random() * 200) + 10,y = Math.round(Math.random() * 100) + 10,console.log(x, y)canvas_ctx.clearRect(0, 0, 310, 155);block_ctx.clearRect(0, 0, 310, 155)block.width = 310draw(canvas_ctx, 'fill')draw(block_ctx, 'clip')}//绘制方块function draw(ctx, operation) {ctx.beginPath()ctx.moveTo(x, y)ctx.arc(x + l / 2, y - r + 2, r, 0.72 * PI, 2.26 * PI)ctx.lineTo(x + l, y)ctx.arc(x + l + r - 2, y + l / 2, r, 1.21 * PI, 2.78 * PI)ctx.lineTo(x + l, y + l)ctx.lineTo(x, y + l)ctx.arc(x + r - 2, y + l / 2, r + 0.4, 2.76 * PI, 1.24 * PI, true)ctx.lineTo(x, y)ctx.lineWidth = 2ctx.fillStyle = 'rgba(255, 255, 255, 0.7)'ctx.strokeStyle = 'rgba(255, 255, 255, 0.7)'ctx.stroke()ctx[operation]()ctx.globalCompositeOperation = 'overlay'}initImg()draw(canvas_ctx, 'fill')draw(block_ctx, 'clip')//添加移动事件var block_slider = document.querySelector("#block");var slider = document.querySelector(".verSliderBlock");var slider_mark = document.querySelector("#bar-mask");//用于判断当前是否是在按住滑块的情况下var yd = falsevar moveX = 0var downX = 0//鼠标按下slider.onmousedown = function(e) {downX = e.clientX;yd = true}//鼠标移动事件function hadleMousemove(e) {if (yd) {moveX = e.clientX - downX;document.querySelector('#slide').innerHTML = ''if (moveX >= 310) {moveX = 310 - 40}if (moveX > -2) {slider.style.backgroundColor = "#1991FA";slider_mark.style.borderWidth = "1px"slider_mark.style.borderColor = "#1991fa"slider_mark.style.width = moveX + 40 + "px";block_slider.style.left = (310 - 40 - 20) / (310 - 40) * moveX + "px";slider.style.left = moveX + "px";}}}//鼠标抬起事件function hadleMouseup(e) {if (yd) {slider.onmousemove = null;console.log(moveX)block_slider.style.left = (310 - 40 - 20) / (310 - 40) * moveX + "px";if (Math.abs((310 - 40 - 20) / (310 - 40) * moveX - x) < 10) {slider.style.background = "url('https://etfinfo.xcf.cn/appletImg/puzzle-success.png')";slider.style.backgroundSize = '100%'setTimeout(() => {rest();var index = layer.open();layer.close(index);o();

})();
第二步 具体页面引用
<!-- 滑动验证人机组件 -->
<script type="text/javascript" src="js/component.js"></script>
// 点击获取验证码 弹出滑动验证码弹框
$("#loginMoudle").slideComponent(function() {successLoad(2); //此处是滑动验证通过后希望执行的方法
});
