Fluid -39- 自定义右键菜单

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：

代码语言：text复制

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

bodyEnd.ejs 文件写入

代码语言：text复制

<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">

<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。

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

js 事件劫持

在 source/vvd_js 中创建 right_menu.js

代码语言：text复制

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";
}
