博客的右键菜单，本质上很简单，就是在当前 Html 界面劫持右键单击事件，禁止默认右键弹出，把自己的右键菜单在当前鼠标位置展示出来。

实现思路

核心技术：自定义网页右键菜单
实现流程：
- 建立右键菜单：通过 hexo 注入定义，自定义 css 实现样式管理
- 劫持右键单击事件： js 实现，关闭默认行为，展示自定义的菜单
- 原始右键功能：为了方便有需要的朋友，将 Ctrl+右键 作为原始右键提供出来
- 展示提示信息：记录当前右键单击次数，在一定次数时展示提示信息以方便需要使用原始右键菜单的访客

实现过程

建立右键菜单

为了不影响正常数据加载，我决定在 BodyEnd 注入该代码段

在 source/_inject 文件夹创建 bodyEnd.ejs 文件，在 scripts/page.js 中引入该注入文件：

hexo.extend.filter.register('theme_inject', function(injects) {
  injects.bodyEnd.file('default', "source/_inject/bodyEnd.ejs");
});

bodyEnd.ejs 文件写入

<div id="tooltip-rightmenu" class="tooltip-rightmenu">如需原始右键菜单请按下 <strong>Ctrl+右键</strong></div>

<div id="rightmenu-wrapper" style="">
  <ul class="list-v rightmenu" id="rightmenu-content">
	  <li class="navigation menuNavigation-Content">
		<a class="nav icon-only fix-cursor-default" onclick="history.back()"><i class="iconfont icon-zuojiantou1"></i></a>
		<a class="nav icon-only fix-cursor-default" onclick="history.forward()"><i class="iconfont icon-youjiantou1"></i></a>
		<a class="nav icon-only fix-cursor-default" onclick="window.location.reload()"><i class="iconfont icon-shuaxin"></i></a>
		<a  aria-label="TOP" href="#" role="button"><i class="iconfont icon-xiangshang"></i></a>
	  </li>

		<hr class="menuLoad-Content" style="display: block;">
	  <li class="menuLoad-Content" style="display: block;">
		<a class="vlts-menu fix-cursor-default" target="_self" href="javascript:;" data-toggle="modal" data-target="#modalSearch" aria-label="Search">
		  <span>
			  <i class="iconfont icon-sousuo1 rightmenu-icon"></i>
			  站内搜索
		  </span>
		</a>
	  </li>

	  <li class="menuLoad-Content" style="display: block;">
		<a class="vlts-menu fix-cursor-default"  href="https://www.zywvvd.com/messagebd/" data-group="link">
		  <span>

	  </li>


	  <li class="menuLoad-Content" style="display: block;">
		<a class="vlts-menu fix-cursor-default" id="help" target="_blank" rel="noopener" href="https://www.foreverblog.cn/go.html" data-group="link">

			  虫洞穿梭
		  </span>
		</a>
	  </li>

	<a id="scroll-top-button" aria-label="TOP" href="#" role="button" style="bottom: 20px; right: 52.6364px;">
        <i class="iconfont icon-xiangshangjiantou" aria-hidden="true"></i>
      </a>

	<hr class="menuLoad-Content" style="display: block;">
	

  </ul>
</div>

<link href="/css/custom.css"type="text/css"rel="stylesheet"/>
<script src="/vvd_js/right_menu.js" type="text/javascript"></script>
<link href="/css/right_menu.css"type="text/css"rel="stylesheet"/>

代码作为示例，事实上需要按照自己需求调整，核心目的是建立右键菜单。

定义右键菜单样式

在 source/css/custom.css 中添加图标（我是放在这里的）

@font-face {
  font-family: "iconfont"; /* Project id 3859637 */
  src: url('//at.alicdn.com/t/c/font_3859637_jxuiuw0et3.woff2?t=1705932159225') format('woff2'),
       url('//at.alicdn.com/t/c/font_3859637_jxuiuw0et3.woff?t=1705932159225') format('woff'),
       url('//at.alicdn.com/t/c/font_3859637_jxuiuw0et3.ttf?t=1705932159225') format('truetype');

在 source/css/right_menu.css 中定义右键菜单样式：

重点参考黑兔小九大佬

div#rightmenu-wrapper {
    display: -webkit-box /* OLD - iOS 6-, Safari 3.1-6 */;
    display: -moz-box /* OLD - Firefox 19- (buggy but mostly works) */;

    -ms-user-select: none;
}

ul.list-v.rightmenu {
    display: -webkit-box /* OLD - iOS 6-, Safari 3.1-6 */;
    display: -moz-box /* OLD - Firefox 19- (buggy but mostly works) */;
    display: block;
	background-color: var(--board-bg-color);
    max-width: 240px;
    overflow: hidden;
}

ul.list-v {
    z-index: 1;
    display: -webkit-box /* OLD - iOS 6-, Safari 3.1-6 */;

}


ul.list-v.rightmenu li.navigation, ul.list-v.rightmenu li.music {

    display: -webkit-flex /* NEW - Chrome */;
    display: flex /* NEW, Spec - Opera 12.1, Firefox 20+ */;
    display: flex;
    justify-content: space-between;
    -webkit-justify-content: space-between;
    -khtml-justify-content: space-between;
    -moz-justify-content: space-between;
    -o-justify-content: space-between;
    -ms-justify-content: space-between;
}

ul.list-v >li {
    white-space: nowrap;
    word-break: keep-all;
}


ul.list-v hr {
    margin-top: 8px;
    margin-bottom: 8px;
}

ul.list-v.rightmenu li.navigation a.nav i, ul.list-v.rightmenu li.music a.nav i {
    margin: 0;
    width: 32px;
    line-height: 32px;
}


ul.list-v >li {
    white-space: nowrap;
    word-break: keep-all;
}

ul.list-v.rightmenu li.navigation a.nav:first-child, ul.list-v.rightmenu li.music a.nav:first-child {
    margin-left: 3px;
}

ul.list-v.rightmenu a.vlts-menu {
    text-overflow: ellipsis;
    overflow: hidden;
    line-height: 36px;
    font-weight: normal;
}

	margin: 0 11px 0 8px;
}

/* 信息提示框 */

.tooltip-rightmenu {

opacity: 0;
z-index: 99;
transition: opacity 1s ease-in-out;
}

.show-tooltip {
opacity: 0.8;
}

js 事件劫持

在 source/vvd_js 中创建 right_menu.js


var right_cilck_num = 0;
window.oncontextmenu = function(e){
	// 检查是否按下了Ctrl键
	if (e.ctrlKey) {
		return true;
	}

	e.preventDefault(); //阻止浏览器自带的右键菜单显示
	var menu = document.getElementById("rightmenu-wrapper");
	menu.style.display = "block"; //将自定义的“右键菜单”显示出来
	menu.style.left = e.clientX + "px";  //设置位置，跟随鼠标
	menu.style.top = e.clientY+"px"; 
	right_cilck_num = right_cilck_num+ 1;
	
	if(right_cilck_num %7== 1){
	      const tooltip = document.getElementById('tooltip-rightmenu');
	      tooltip.classList.add('show-tooltip');

	      // 3秒后隐藏提示框
	      setTimeout(() => {
		tooltip.classList.remove('show-tooltip');
	      }, 3000);
	}
}
window.onclick = function(e){ //点击窗口，右键菜单隐藏
	var menu = document.getElementById("rightmenu-wrapper");
	menu.style.display = "none";
}
