一、前言
实现像微信一样的点击右键后出现操作菜单，对选中的数据项进行相应的操作，接下来介绍使用原生vue实现右键菜单的方法。
二、页面代码
<div v-if="isShow" class="warn_box">
<div
v-for="(item, index) in warnList"
:key="index"
:class="{ 'list': true, 'isTop': item.isTop, 'isSelected': activeIndex === index }"
@click="itemClick(index, Number(item.code))"
@contextmenu.prevent.stop="showMenu($event, index, item.configId)"
>
<!-- {
{ item.name }} -->
<div
class="all"
>
<div class="left">
<div class="left_top">
<EllipsisPop :content="item.name" :row-num="1" width="180px"></EllipsisPop>
</div>
<div class="left_bottom">{
{ item.code }}</div>
</div>
<div class="right">
<div class="right_top">{
{ filterTime(item.maxCreateTime) }}</div>
<div
v-if="item.untreatedTotal"
class="right_bottom"
>
<el-badge
:value="item.untreatedTotal"
:max="999"
class="badge"
>
</el-badge>
</div>
</div>
</div>
</div>
<div v-if="isShowMenu" class="menu_box" :style="{
'left': menuLeft + 'px', 'top': menuTop + 'px'}">
<div class="menu">
<div v-if="!isNowTop" class="menu_item item_text" @click.stop="stick(true)">置顶</div>
<div v-else class="menu_item item_text" @click.stop="stick(false)">取消置顶</div>
<!-- <div class="menu_item item_text" @click.stop="deleteList">删除</div> -->
<el-popover v-model="showDelPop" placement="top" width="160" trigger="click">
<!-- <p>请确定是否删除？</p> -->
<div style="text-align: center; margin: 0">
<p>请确定是否删除？</p>
<el-button size="small" @click="showDelPop = false">取消</el-button>
<el-button type="primary" size="small" @click.stop="deleteList">确定</el-button>
</div>
<template #reference>
<div class="menu-item item_text" @click.stop="()=>{}">删除</div>
</template>
</el-popover>
</div>
</div>
</div>
.menu_box {
position: fixed;
z-index: 1004;
background-color: #fff;
// border-radius: 5px;
.menu{
width: 100px;
text-align: left;
// padding: 5px;
box-shadow: 0 2px 12px 0 rgba(0,0,0,0.1);
.menu_item{
height: 24px;
line-height: 22px;
// margin-top: 5px;
}
.item_text{
color: #171A1D;
cursor: pointer;
padding: 4px 20px;
// border-radius: 3px;
transition: all .2s ease-in;
}
.item_text:hover {
background-color: #E9EAEC;
}
}
}
- @contextmenu.prevent.stop 为阻止浏览器的右键点击菜单事件
- isShowMenu: 来控制菜单的显示
三、页面逻辑
- 同时我们要为其出现的地方进行调整 menuTop，menuLeft，在展示 menu 的时候我们将 event 的页面位置属性 e.pageX 和 e.pageX 拿来赋值
- 我们需要在页面创建的时候增加 click 和 mousedonw 的监听，这样就可以在我们点击别的地方的时候将菜单隐藏
// 右键菜单
const isShowMenu = ref(false) // 控制是否显示右键菜单
const menuLeft = ref(0)
const menuTop = ref(0)
const openMenuConfigId = ref(0) // 打开右键菜单的那一行的configId
const isNowTop = ref(false) // 是否已置顶
const showMenu = async(e:any, index:number, configId:number):Promise<void> => {
// console.log(e, index, configId)
// eslint-disable-next-line
const data = await window.app.windowGetData(store.userBaseInfo.username + '.data.warn')
data.forEach((item:any) => {
if (item.configId === configId) {
if (item.isTop) {
isNowTop.value = true
} else {
isNowTop.value = false
}
}
})
openMenuConfigId.value = configId
isShowMenu.value = true
menuLeft.value = e.pageX
menuTop.value = e.pageY
}
// 置顶
const stick = async(status:boolean):Promise<void> => {
// eslint-disable-next-line
let data = await window.app.windowGetData(store.userBaseInfo.username + '.data.warn')
data.forEach((item:any) => {
if (item.configId === openMenuConfigId.value) {
item.isTop = status
}
})
const topList:any[] = []
data.forEach((item:any) => {
if (item.isTop) {
topList.push(item)
}
})
topList.sort((a:any, b:any) => (b.maxCreateTime - a.maxCreateTime))
data = data.filter((item:any) => (item.isTop === false))
data.sort((a:any, b:any) => (b.maxCreateTime - a.maxCreateTime))
data = topList.concat(data)
warnList = JSON.parse(JSON.stringify(data))
$forceUpdate()
// eslint-disable-next-line
window.app.windowStoreData(store.userBaseInfo.username + '.data.warn', data)
clockMenu()
}
// 删除
const showDelPop = ref(false)
const deleteList = async():Promise<void> => {
// eslint-disable-next-line
let data = await window.app.windowGetData(store.userBaseInfo.username + '.data.warn')
data = data.filter((item:any) => (item.configId !== openMenuConfigId.value))
warnList = JSON.parse(JSON.stringify(data))
$forceUpdate()
// eslint-disable-next-line
window.app.windowStoreData(store.userBaseInfo.username + '.data.warn', data)
clockMenu()
}
// 关闭菜单
const clockMenu = ():void => {
isShowMenu.value = false
}
// 失去焦点时关闭右击菜单
mounted() {
//失去焦点时关闭右击菜单
document.addEventListener("click", (e) => {
if (!this.$refs.rightMenu.contains(e.target))
this.rightMenuVisible = false;
});
}
