vue自定义右键菜单 vue中怎样自定义右键菜单详解
她的开呀 人气:0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:
<li v-for="item in resourceList" :key="item.id" @click="handleClickFolder(item)" @contextmenu.prevent="openMenu($event,item)" > </li>
在页面编写右键菜单内容:
<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>
在data()中定义需要的变量属性
data() { return { visible: false, top: 0, left: 0 } }
观察visible的变化,来触发关闭右键菜单,调用关闭菜单的方法
watch: { visible(value) { if (value) { document.body.addEventListener('click', this.closeMenu) } else { document.body.removeEventListener('click', this.closeMenu) } } }
在method中定义打开右键菜单和关闭右键菜单的两个方法
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中写右键菜单的样式
.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; }
