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:
1
2
3
4
5
6
7
8
|
< 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:
1
2
3
4
5
6
7
8
|
<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
1
2
3
4
5
6
7
|
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
1
2
3
4
5
6
7
8
9
|
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
1
2
3
4
5
6
7
8
9
10
11
12
13
14
|
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
安装:
1
|
npm install vue-contextmenu --save |
引用:
1
2
|
import VueContextMenu from 'vue-contextmenu' Vue.use(VueContextMenu) |

<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> |
