利用element-plus中的el-menu实现简单右键
实现如下
<template><main class="mainClass" @contextmenu="showMenu($event)"> </main><el-menu:default-active="1"class="el-menu-demo"mode="vertical":collapse="isCollapse"v-show="menuShow"@close="hideMenu"@open="openItem"ref="menuRef":style="{ left: left + 'px', top: top + 'px' }"><el-menu-item index="1">Processing Center</el-menu-item><el-sub-menu index="2"><template #title>Workspace</template><el-menu-item index="2-1">item one</el-menu-item><el-menu-item index="2-2">item two</el-menu-item><el-menu-item index="2-3">item three</el-menu-item></el-sub-menu></el-menu></template><script setup>import { watch ,ref } from 'vue';const activeIndex = ref('0')
const menuShow = ref(false)
const isCollapse = ref(true)
const menuRef = ref(null)
const left = ref(0)
const top = ref(0)function hideMenu()
{menuShow.value = false;
}
function openItem(index, indexPath)
{console.log(index, indexPath)
}function showMenu(e)
{menuShow.value = true;left.value = e.clientX+1;top.value = e.clientY+1;//阻止默认行为e.preventDefault();
}//监听menuShow的变化，当它为true时，给body绑定一个点击事件，当点击时，隐藏menu
watch(menuShow,(newValue, oldValue) => {if(newValue){document.body.addEventListener('click', hideMenu)} else {document.body.removeEventListener('click', hideMenu)}
})</script><style scoped>
.mainClass
{width: 500px;height: 500px;background-color: #f0f0f0;
}
.el-menu-demo
{position: absolute;left: 0;top: 0;z-index: 100;width: 120px;/* background-color: rgb(167, 184, 184); */
}
</style>推荐一个 v-contextmenu (cybernika.net)
