环境：vue-admin-template vue 2.6.10 element-ui 2.7.0
1、自定义组件，文件位置：src/components/mentContext
<template>
<!-- @mousedown.stop 阻止冒泡事件-->
<!-- @contextmenu.prevent 阻止右键的默认事件 -->
<div id="dropMenu"
:style="style"
style="display: block;"
v-show="show"
@mousedown.stop
@contextmenu.prevent>
<slot></slot>
</div>
</template>
<script>
export default {
name:"menuContext",
data() {
return {
triggerShowFn: () => {
},
triggerHideFn: () => {
},
x: null,
y: null,
style: {},
binded: false
}
},
props: {
target: null,
show: Boolean
},
mounted() {
this.bindEvents()
},
watch: {
show(show) {
if (show) {
this.bindHideEvents()
} else {
this.unbindHideEvents()
}
},
target(target) {
this.bindEvents()
}
},
methods: {
// 初始化事件
bindEvents() {
this.$nextTick(() => {
var that = this
if (!this.target || this.binded) return
this.triggerShowFn = this.contextMenuHandler.bind(this)
this.target.addEventListener('contextmenu', this.triggerShowFn)
//this.binded = true
})
},
// 取消绑定事件
unbindEvents() {
if (!this.target) return
this.target.removeEventListener('contextmenu', this.triggerShowFn)
},
// 绑定隐藏菜单事件
bindHideEvents() {
this.triggerHideFn = this.clickDocumentHandler.bind(this)
document.addEventListener('mousedown', this.triggerHideFn)
document.addEventListener('mousewheel', this.triggerHideFn)
},
// 取消绑定隐藏菜单事件
unbindHideEvents() {
document.removeEventListener('mousedown', this.triggerHideFn)
document.removeEventListener('mousewheel', this.triggerHideFn)
},
// 鼠标按压事件处理器
clickDocumentHandler(e) {
this.$emit('update:show', false) //隐藏
},
// 右键事件事件处理
contextMenuHandler(e) {
e.target.click()//这个是因为我需要获取tree节点的数据，所以我通过点击事件去获取数据
this.x = e.clientX - 240
this.y = e.clientY - 110
this.layout()
this.$emit('update:show', true) //显示
e.preventDefault()
e.stopPropagation()
this.$emit('targetElement', e.target) //我还要获取右键的DOM元素进行操作
},
// 布局
layout() {
this.style = {
left: this.x + 'px',
top: this.y + 'px'
}
}
}
}
</script>
<style lang="scss">
#dropMenu {
position: absolute;
margin: 0;
padding: 0;
80px;
height: auto;
border: 1px solid #ccc;
border-radius: 4px;
ul {
list-style: none;
margin: 0;
padding: 0;
li {
100%;
text-align: center;
height: 30px;
line-height: 30px;
background: #eee;
margin-bottom: 1px;
cursor: pointer;
}
}
}
</style>
2、调用，src/views 自己的项目目录里
<template>
<div class="app-container">
<h2>当前目录:</h2>
<h4>{{ current_path }}</h4>
<el-input
placeholder="输入关键字进行过滤"
v-model="filterText">

<!-- 树形结构 -->
<el-tree
id="modelTree"
ref="tree"
:data="treedata"
:props="defaultProps"
class="filter-tree"
accordion
node-key="id"
:filter-node-method="filterNode"
>
</el-tree>
<!-- 右键菜单 -->
<menu-context
:target="contextMenuTarget"
:show="isShowDrop"
@update:show="(show) => isShowDrop = show"
@targetElement="getTargetElement">
<ul> <!--按需展示按钮-->
<li v-show="isShowDelete" @click="deleteOne">删除</li>
<li v-show="isShowAdd" @click="add">添加</li>
<li v-show="isShowEdit" @click="editNode">编辑</li>
<li v-show="isShowLink" @click="linkModels">关联</li>
<li v-show="isShowMove" @click="move">转移</li>
</ul>
</menu-context>
<el-dialog
:title="textMap[dialogStatus]"
:visible.sync="dialogFormVisible"
:close-on-click-modal="false"
width="70%"
top="5vh"
@open="resetForm('dataForm')"
>
<el-form ref="dataForm" :rules="rules" :model="temp" label-position="left" label-width="100px">
<el-form-item v-if="false" label="ID" prop="id">
<el-input v-model="temp.id"/>
</el-form-item>
<el-form-item label="脚本路径" prop="path">
<p>{{ temp.path }}</p>
</el-form-item>
<el-form-item label="脚本名称" prop="name">

</el-form-item>
<el-form-item label="脚本内容" prop="filebody">
<codemirror v-model="temp.filebody" :options="cmOptions"/>
</el-form-item>
</el-form>
<div slot="footer" class="dialog-footer">
<el-button @click="dialogFormVisible = false">
取消
</el-button>
<el-button type="primary" @click="dialogStatus==='create'?createData():updateData()">
提交
</el-button>
</div>
