介绍:
这是给Typecho博客用的 复制代码 插件。
仿的CSDN,只有鼠标放到代码块,才会显示复制代码,鼠标从代码块移开,复制代码方框消失。支持一篇文章多个代码块的单独复制
点击复制代码,会出现成功复制的提示。之后延迟一秒后,又会重置为复制代码。
具体JavaScript代码:
[JavaScript] 纯文本查看 复制代码 //html5 给typecho添加 复制代码 功能
// by 兔子昂
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;\
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);
}
