vue添加自定义右键菜单的完整实例
(编辑:jimmy 日期: 2024/12/23 浏览:3 次 )
一、写原生方法
1.在所编辑的页面,需要添加右键菜单的元素,绑定contextmenu事件,如下:
<li v-for="item in resourceList" :key="item.id" @click="handleClickFolder(item)" @contextmenu.prevent="openMenu($event,item)" > ... </li>
2.在页面编写右键菜单内容:
<ul v-show="visible" :style="{left:left+'px',top:top+'px'}" class="contextmenu"> <!-- <li v-if="rightClickItem.fileType==99" @click="handleClickFolder(rightClickItem)">打开</li> <li @click="handleDelete(rightClickItem)">删除</li> <li @click="handleDownloadFile(rightClickItem)" v-if="rightClickItem.fileType!=99">下载</li> <li @click="handlePreviewFile(rightClickItem)" v-if="rightClickItem.fileType!=99">预览</li> <li @click="handleUpdate(rightClickItem)">编辑</li> --> <li>内容</li> </ul>
3.在data()中定义需要的变量属性
data() { return { visible: false, top: 0, left: 0 } }
4.观察visible的变化,来触发关闭右键菜单,调用关闭菜单的方法
watch: { visible(value) { if (value) { document.body.addEventListener('click', this.closeMenu) } else { document.body.removeEventListener('click', this.closeMenu) } } }
5.在method中定义打开右键菜单和关闭右键菜单的两个方法
openMenu(e, item) { this.rightClickItem = item; var x = e.pageX; var y = e.pageY; this.top = y; this.left = x; this.visible = true; }, closeMenu() { this.visible = false; }
6.在style中写右键菜单的样式
.contextmenu { margin: 0; background: #fff; z-index: 3000; position: absolute; list-style-type: none; padding: 5px 0; border-radius: 4px; font-size: 12px; font-weight: 400; color: #333; box-shadow: 2px 2px 3px 0 rgba(0, 0, 0, 0.3); } .contextmenu li { margin: 0; padding: 7px 16px; cursor: pointer; } .contextmenu li:hover { background: #eee; }

二、使用插件vue-context-menu

github地址
安装:
npm install vue-contextmenu --save
引用:
import VueContextMenu from 'vue-contextmenu' Vue.use(VueContextMenu)
使用:
<template> <div id="app" @contextmenu="showMenu" style="width: 100px;height: 100px;margin-top: 20px;background: red;"> <vue-context-menu :contextMenuData="contextMenuData" @savedata="savedata" @newdata="newdata"></vue-context-menu> </div> </template> <script> export default { name: 'app', data () { return { // contextmenu data (菜单数据) contextMenuData: { // the contextmenu name(@1.4.1 updated) menuName: 'demo', // The coordinates of the display(菜单显示的位置) axis: { x: null, y: null }, // Menu options (菜单选项) menulists: [{ fnHandler: 'savedata', // Binding events(绑定事件) icoName: 'fa fa-home fa-fw', // icon (icon图标 ) btnName: 'Save' // The name of the menu option (菜单名称) }, { fnHandler: 'newdata', icoName: 'fa fa-home fa-fw', btnName: 'New' }] } } }, methods: { showMenu () { event.preventDefault() var x = event.clientX var y = event.clientY // Get the current location this.contextMenuData.axis = { x, y } }, savedata () { alert(1) }, newdata () { console.log('newdata!') } } } </script>
