通过一个js完成很简单且很实用
步骤一: 新建codecopy.js在主题文件夹js里面新建一个codecopy.js文件。在文件里放入以下代码:
var codeblocks = document.getElementsByTagName("pre") //循环每个pre代码块,并添加 复制代码 for (var i = 0; i < codeblocks.length; i++) { //显示 复制代码 按钮 currentCode = codeblocks[i] currentCode.style = "position: relative;" var copy = document.createElement("div") copy.style = "position: absolute;right: 4px;\\ top: 4px;background-color: white;padding: 2px 8px;\\ margin: 8px;border-radius: 4px;cursor: pointer;\\ z-index: 9999;\\ box-shadow: 0 2px 4px rgba(0,0,0,0.05), 0 2px 4px rgba(0,0,0,0.05);" copy.innerHTML = "复制" currentCode.appendChild(copy) //让所有 "复制"按钮 全部隐藏 copy.style.visibility = "hidden" } for (var i = 0; i < codeblocks.length; i++) { !function (i) { //鼠标移到代码块,就显示按钮 codeblocks[i].onmouseover = function () { codeblocks[i].childNodes[1].style.visibility = "visible" } //执行 复制代码 功能 function copyArticle(event) { const range = document.createRange(); //范围是 code,不包括刚才创建的div range.selectNode(codeblocks[i].childNodes[0]); const selection = window.getSelection(); if (selection.rangeCount > 0) selection.removeAllRanges(); selection.addRange(range); document.execCommand(\'copy\'); codeblocks[i].childNodes[1].innerHTML = "复制成功" setTimeout(function () { codeblocks[i].childNodes[1].innerHTML = "复制" }, 1000); //清除选择区 if (selection.rangeCount > 0) selection.removeAllRanges(); 0 } codeblocks[i].childNodes[1].addEventListener(\'click\', copyArticle, false); }(i); !function (i) { //鼠标从代码块移开 则不显示复制代码按钮 codeblocks[i].onmouseout = function () { codeblocks[i].childNodes[1].style.visibility = "hidden" } }(i); }
步骤二 :应用codecopy.js打开模板目录下的footer.php文件,在文件末尾的前添加下面一行。
<script src="<?php $this->options->themeUrl(); ?>js/codecopy.js"></script>
大功告成,非常适用,待研究出来复制弹窗结合使用,绝绝子
