最近做的一个项目是基于 vue
+ AntDesign
的。由于项目要求,需要在 Table
组件的行内点右键的时候弹出菜单。在线演示地址及最终效果图如下:
首先新建一个Table组件的实例:
<a-table :columns="columns" :rowKey="record => { return record.INDEX;}" :dataSource="tableData" /> ... const columns = [ { title: "序号", dataIndex: "INDEX" }, { title: "主题大类", dataIndex: "THEME" }, { title: "中文名称", dataIndex: "CN_NAME" }, { title: "英文名称", dataIndex: "EN_NAME" } ]; ... data() { return { columns, tableData: [ { INDEX: 0, THEME: "基础数据", CN_NAME: "地区", EN_NAME: "Area" }, { INDEX: 1, THEME: "个人信息", CN_NAME: "姓名", EN_NAME: "Name" } ] }; }
新建一个Menu菜单组件的实例及其样式:
<a-menu :style="menuStyle" v-if="menuVisible"> <a-menu-item>{{menuData.THEME}}</a-menu-item> <a-menu-item>{{menuData.CN_NAME}}</a-menu-item> <a-menu-item>{{menuData.EN_NAME}}</a-menu-item> </a-menu> ... data() { return { ... menuData: {}, menuVisible: false, menuStyle: { position: "absolute", top: "0", left: "0", border: "1px solid #eee" } }; }
注意这里给Menu加样式主要是为了实现点右键时Menu菜单出现在鼠标位置,所以我用了position: "absolute"来定义。
下面就是最重要的,通过Table组件的customRow参数来设置鼠标右键事件。首先添加Table组件的customRow参数:
<a-table ... :customRow="customClick" />
然后在data里添加customClick的右键方法,以及在methods里添加body的click方法。添加body的click方法是为了在出现右键菜单后,点击左键时关闭菜单。
data() { return { ... customClick: record => ({ on: { contextmenu: e => { e.preventDefault(); this.menuData = record; this.menuVisible = true; this.menuStyle.top = e.clientY + "px"; this.menuStyle.left = e.clientX + "px"; document.body.addEventListener("click", this.bodyClick); } } }) }; }, methods: { bodyClick() { this.menuVisible = false; document.body.removeEventListener("click", this.bodyClick); } }
至此,Ant Design Vue中Table组件行内右键菜单就实现了。完整代码如下:
<template> <div> <a-table :columns="columns" :rowKey="record => { return record.INDEX;}" :dataSource="tableData" :customRow="customClick" /> <a-menu :style="menuStyle" v-if="menuVisible"> <a-menu-item>{{menuData.THEME}}</a-menu-item> <a-menu-item>{{menuData.CN_NAME}}</a-menu-item> <a-menu-item>{{menuData.EN_NAME}}</a-menu-item> </a-menu> </div> </template> <script> const columns = [ { title: "序号", dataIndex: "INDEX" }, { title: "主题大类", dataIndex: "THEME" }, { title: "中文名称", dataIndex: "CN_NAME" }, { title: "英文名称", dataIndex: "EN_NAME" } ]; export default { data() { return { columns, tableData: [ { INDEX: 0, THEME: "基础数据", CN_NAME: "地区", EN_NAME: "Area" }, { INDEX: 1, THEME: "个人信息", CN_NAME: "姓名", EN_NAME: "Name" } ], menuData: {}, menuVisible: false, menuStyle: { position: "absolute", top: "0", left: "0", border: "1px solid #eee" }, customClick: record => ({ on: { contextmenu: e => { e.preventDefault(); this.menuData = record; this.menuVisible = true; this.menuStyle.top = e.clientY + "px"; this.menuStyle.left = e.clientX + "px"; document.body.addEventListener("click", this.bodyClick); } } }) }; }, methods: { bodyClick() { this.menuVisible = false; document.body.removeEventListener("click", this.bodyClick); } } }; </script>
