1、首先，我们准备好拼图所需的素材图片。注意图片的命名格式。
3、我们在记事本里写下如下代码：<!DOCTYPE html><html><head> <meta charset="utf-8媪青怍牙"> <title></title> <style> .box{ float: left; } img{ width: 150px; height:150px; } #puzzle{ font-size: 0; margin:80px auto; padding: 5px; width: 460px; } </style></head><body> <div id="puzzle"> <div class="box"><img alt="1"></div> <div class="box"><img alt="2"></div> <div class="box"><img alt="3"></div> <div class="box"><img alt="4"></div> <div class="box"><img alt="5"></div> <div class="box"><img alt="6"></div> <div class="box"><img alt="7"></div> <div class="box"><img alt="8"></div> <div class="box"><img alt="9"></div> </div> <script> var image = document.getElementsByTagName("img"); var box = document.getElementsByClassName("box"); image.draggable = true; var source = ""; var nowImage; var nowImageBox; var thenImage; for(let i=0;i<image.length;i++){ source = "picture"+i+".jpg"; image[i].setAttribute("src",source); image[i].onmousedown = function(){ nowImage = this; nowImageBox = this.parentNode; } box[i].ondragover = function(event){ event.preventDefault(); } box[i].ondrop = function(event){ thenImage = box[i].childNodes[0]; box[i].appendChild(nowImage); nowImageBox.appendChild(thenImage); } } </script></body></html>
5、我们鼠标拖住一个图片至另一个图片位置，可交换两个图片的位置。
