JavaScript一键复制
TANKING 人气:0引言
有时候为了方便用户快速复制页面的内容,一般的做法就是添加一个按钮给用户点击一下就复制下来了,这边使用JavaScript原生的方法进行设置剪贴板。
代码
copy.html
<!DOCTYPE html> <html> <head> <title>一键复制demo</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=1.0,user-scalable=0,viewport-fit=cover"> <style type="text/css"> *{ padding:0; margin:0; } h2{ text-align: center; margin-top: 20px; } #neirong{ width: calc(90% - 20px); padding:10px 10px; margin:20px auto; background: #eee; border-radius: 5px; } #copy{ border:none; width: 90%; height: 45px; background: #39f; font-size: 16px; color: #fff; font-weight: bold; border-radius: 5px; margin: 0 auto; display: block; } </style> </head> <body> <h2>一键复制demo</h2> <div id="neirong">这是内容这是内容这是内容这是内容</div> <button id="copy">复制</button> <script> function copyArticle(event){ const range = document.createRange(); range.selectNode(document.getElementById('neirong')); const selection = window.getSelection(); if(selection.rangeCount > 0) selection.removeAllRanges(); selection.addRange(range); document.execCommand('copy'); alert("复制成功"); } window.onload = function () { var obt = document.getElementById("copy"); obt.addEventListener('click', copyArticle, false); } </script> </body> </html>
