一.下载第三方插件clipboard.js

clipboard.js
clipboard.min.js (推荐)
保存到 themes/hexo-theme-xxxx/source/js/ 下

二. 创建js文件

创建clipboard-use.js 和 clipboard.min.js 保存到 themes/hexo-theme-xxxx/source/js/ 下，其内容如下:

/*页面载入完成后，创建复制按钮*/
!function (e, t, a) { 
  /* code */
  var initCopyCode = function(){
    var copyHtml = '';
    copyHtml += '<button class="btn-copy" data-clipboard-snippet="">';
    copyHtml += '  <i class="fa fa-globe"></i><span>copy</span>';
    copyHtml += '</button>';
    $(".highlight .code pre").before(copyHtml);
    new ClipboardJS('.btn-copy', {
        target: function(trigger) {
            return trigger.nextElementSibling;
        }
    });
  }
  initCopyCode();
}(window, document);

在末尾添加,注意一定先添加 clipboard.min ，另外后面不带.js后缀

<%- js('js/clipboard.min') %>
<%- js('js/clipboard-use') %>

四. 添加css样式

copy.highlight{
  position: relative;
}
.btn-copy {
    display: inline-block;
    cursor: pointer;
    background-color: #eee;
    background-image: linear-gradient(#fcfcfc,#eee);
    border: 1px solid #d5d5d5;
    border-radius: 3px;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
    -webkit-appearance: none;
    font-size: 13px;
    font-weight: 700;
    line-height: 20px;
    color: #333;
    -webkit-transition: opacity .3s ease-in-out;
    -o-transition: opacity .3s ease-in-out;
    transition: opacity .3s ease-in-out;
    padding: 2px 6px;
    position: absolute;
    right: 5px;
    top: 5px;
    opacity: 0;
}
.btn-copy span {
    margin-left: 5px;
}
.highlight:hover .btn-copy{
  opacity: 1;
}
