在所編輯的頁(yè)面湖雹，需要添加右鍵菜單的元素或听，綁定contextmenu事件哲身，如下：
<li
v-for="item in resourceList"
:key="item.id"
@click="handleClickFolder(item)"
@contextmenu.prevent="openMenu($event,item)"
>
</li>
在頁(yè)面編寫右鍵菜單內(nèi)容:
<ul v-show="visible" :style="{left:left+'px',top:top+'px'}" class="contextmenu">
<!-- <li v-if="rightClickItem.fileType==99" @click="handleClickFolder(rightClickItem)">打開</li>
<li @click="handleDelete(rightClickItem)">刪除</li>
<li @click="handleDownloadFile(rightClickItem)" v-if="rightClickItem.fileType!=99">下載</li>
<li @click="handlePreviewFile(rightClickItem)" v-if="rightClickItem.fileType!=99">預(yù)覽</li>
<li @click="handleUpdate(rightClickItem)">編輯</li> -->
<li>內(nèi)容</li>
</ul>
觀察visible的變化做修，來(lái)觸發(fā)關(guān)閉右鍵菜單脚猾，調(diào)用關(guān)閉菜單的方法
watch: {
visible(value) {
if (value) {
document.body.addEventListener('click', this.closeMenu)
} else {
document.body.removeEventListener('click', this.closeMenu)
}
}
}
在method中定義打開右鍵菜單和關(guān)閉右鍵菜單的兩個(gè)方法
openMenu(e, item) {
this.rightClickItem = item;
let x = e.clientX;
let y = e.clientY;
this.top = y;
this.left = x;
this.visible = true;
},
closeMenu() {
this.visible = false;
}
在style中寫右鍵菜單的樣式
.contextmenu {
margin: 0;
background: #fff;
z-index: 3000;
position: fixed;
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-color: rgb(3, 125, 243);;
color: white;
}
