Vue实现自定义右击删除菜单的示例

觉醒法师 人气:0

一、定义和使用

oncontextmenu 事件在元素中用户右击鼠标时触发并打开上下文菜单。

注意:所有浏览器都支持 oncontextmenu 事件, contextmenu 元素只有 Firefox 浏览器支持。

二、语法

HTML 中:

<element oncontextmenu="myScript">

JavaScript 中:

object.oncontextmenu=function(){myScript};

JavaScript 中, 使用 addEventListener() 方法:

object.addEventListener("contextmenu", myScript);

jQuery中,使用on监听事件

$(document).on('contextmenu', myScript);
注意: Internet Explorer 8 及更早 IE 浏览器版本不支持 addEventListener() 。

三、使用细节

是否支持冒泡:

Yes

是否可以取消:

Yes

事件类型:

MouseEvent

支持的 HTML 标签:

所有 HTML 元素

四、案例

这通过一个小案例,在考勤统计列表中,每行中对应某员工这月周期内的每天考勤数据;如果某条记录需要删除,这里通过在记录上直接右击出现删除菜单,操作起来则更为方便。如下图:

4.1 自定义右击删除菜单步骤

通过DOM对象监听鼠标点击事件

触发鼠标点击事件,获取鼠标当前浏览器位置

根据当前位置重新调整自定义contextmenu的位置

显示自定义contextmenu

4.2 技术点

这里使用Vue技术框架来做这个案例,统计列表使用是element-ui中的table组件,事件监听和数据获取通过jquery实现,在开发前请将其通过npm进行安装。

//安装element-ui
npm i element-ui -S
//安装jquery
npm i jquery -S

4.3 html代码

这里通过列数据中isDate判断该列是否渲染为对应日期列,渲染日期相对应的考勤记录时,需要追加data-prop和data-id进行数据传递,后续执行删除操作时会使用到。

<template>
  <div class="list-wrap">
    <el-table
          stripe
          :data="tableData"
                class="list-table"
          style="width: 100%">
                <el-table-column type="selection" width="55" fixed="left"></el-table-column>
                <template v-for="(item, index) in tableColumn">
                    <el-table-column :prop="item.prop" :label="item.name" :key="index" :width="item.width" v-if="item.isDate">
                        <template slot-scope="scope">
                            <span class="date-cell" v-html="scope.row[item.prop]"
                                        :data-prop="item.prop"
                                        :data-id="scope.row['id_'+item.prop]"></span>
                        </template>
                    </el-table-column>
                    <el-table-column :prop="item.prop" :label="item.name" :key="index" :width="item.width" v-else fixed="left"></el-table-column>
                </template>
        </el-table>
  </div>
</template>
 
<style lang="scss">
@import './index.scss';
</style>

4.4 CSS样式

.date-cell类选择器对考勤记录数据进行样式修改,更改鼠标为小手图标,并禁止选择文本内容,为避免后期右击时会误操作选中内容。

.menu-box类选择器为右击菜单增加基础样式。

.date-cell{ cursor: pointer;
  -moz-user-select:none; /*火狐*/
  -webkit-user-select:none; /*webkit浏览器*/
  -ms-user-select:none; /*IE10*/
  -khtml-user-select:none; /*早期浏览器*/
  user-select:none;
}
 
.menu-box{
  position: absolute;
 
  ul.list{
    background-color: #fff;
    border: 1px solid #ccc;
    li{
      border-top: 1px solid #ccc;
      padding: 6px 15px;
      font-size: 14px;
      line-height: 1.5;
      color: #666;
      list-style: none;
      cursor: pointer;
 
      &:first-child{
        border-top: 0;
      }
    }
  }
}

4.5 基础数据

变量tableData用于存储员工考勤数据,变量tableColumn用于存储表格列头部数据定义,在获取考勤记录后,动态追加日期列到变量tableColumn中。

<script> 
  export default {
    data(){
      return {
        tableData: [],
        tableColumn: [
            {prop: "name", name: "姓名", width: "80px"},
            {prop: "workday", name: "实际到岗/天", width: "100px"},
        ]
      }
    },
    created() {
      
    },
    methods: {
    
    }
  }
</script>

此时页面样式如下图:

4.6 模拟数据

这里在目录位置新建demo.json文件,将以下数据拷入即可。

[
  {"id":1482,"name":"张三","record":["08:30","18:00"],"recorddate":"2023-01-01"},

  {"id":1369,"name":"王五","record":["08:30","18:00"],"recorddate":"2023-01-02"}
]

4.7 添加日期列

引入刚才创建好的demo.json文件,导致模拟数据。变量tableData用于存储考勤数据,变量tableColumn用于存储表格列数据,在updateList()函数执行后,获取全部唯一日期数据,和全部用户数据,分别存储到tableData和tableColumn变量中。

由于这里是通过模拟数据实现的功能效果,后期在项目中,相应数据是通过接口查询获取而且的。

<script>
  import DemoData from './demo.json'
 
  export default {
    data(){
      return {
        tableData: [],
        tableColumn: [
            {prop: "name", name: "姓名", width: "80px"},
            {prop: "workday", name: "实际到岗/天", width: "100px"},
        ]
      }
    },
    created() {
      this.updateList();
    },
    methods: {
 
      //加载列表数据
      updateList(){
        //获取日期列表
        let dateColumn = [],
            employeeList = [];
 
        //循环获取唯一 列日期 和 唯一 员工信息
        DemoData.map(item => {
          if(!dateColumn.includes(item.recorddate)){
            dateColumn.push(item.recorddate);
          }
          if(!employeeList.includes(item.name)){
            employeeList.push(item.name);
          }
        });
        //升序排序
        dateColumn.sort();
        //修改列长度,以免name和workday固定列被替换
        this.tableColumn.length = 2;
        //追加日期列
        this.tableColumn = this.tableColumn.concat(dateColumn.map(item => {
          return {
            prop: item,
            name: item,
            width: "100px",
            isDate: true
          }
        }));
      }
      //end
    }
  }
</script>

以上代码完成后,日期列则可以正常显示出来了,如下图:

4.8 重组行数据

通过变量employeeList存储的员工信息,遍历查询模拟数据中各自对应的考勤记录,并通过变量dateColumn中存储的日期作为键,存储到对应员工信息中。

<script>
  import DemoData from './demo.json'
 
  export default {
    data(){
      return {
        tableData: [],
        tableColumn: [
            {prop: "name", name: "姓名", width: "80px"},
            {prop: "workday", name: "实际到岗/天", width: "100px"},
        ]
      }
    },
    created() {
      this.updateList();
    },
    methods: {
 
      //加载列表数据
      updateList(){
        //获取日期列表
        let dateColumn = [],
            employeeList = [];
 
        //循环获取唯一 列日期 和 唯一 员工信息
        DemoData.map(item => {
          if(!dateColumn.includes(item.recorddate)){
            dateColumn.push(item.recorddate);
          }
          if(!employeeList.includes(item.name)){
            employeeList.push(item.name);
          }
        });
        //升序排序
        dateColumn.sort();
        //修改列长度,以免name和workday固定列被替换
        this.tableColumn.length = 2;
        //追加列
        this.tableColumn = this.tableColumn.concat(dateColumn.map(item => {
          return {
            prop: item,
            name: item,
            width: "100px",
            isDate: true
          }
        }));
 
        //重组员工考勤数据,一行显示考勤记录
        this.tableData = employeeList.map(item => {
          let nData = {},
              tmp = null,
              realWorkSize = 0;
 
          //获取对应员工的考勤记录
          dateColumn.forEach(key => {
            tmp = DemoData.filter(sub => sub.name == item && sub.recorddate == key);
            if(tmp.length==1&&tmp[0]['record'].length==2){
              //记录考勤数据
              nData[key] = tmp[0]['record'][0] + '<br />' + tmp[0]['record'][1];
              //保存对应考勤记录的ID
              nData['id_'+key] = tmp[0]['id'];
              //统计到岗天数
              realWorkSize++;
            }else{
              nData[key] = '-';
            }
          })
 
          return {
           name: item,
           workday: realWorkSize,
           ...nData
          }
        });
      }
      //end
    }
  }
</script>

此时模拟数据中考勤记录都正常显示在页面中了,如下图:

五、自定义右击菜单

此时我们可以来实现自定义右击菜单了,这里只简单讲解下实现方法和步骤,如有实际需求可对此功能进行封装处理,这里先用散装代码实现此功能。

5.1 准备工作

首先引入jquery,并且添加禁用右击菜单的鼠标事件,代码如下:

<script>
  import DemoData from './demo.json'
  import $ from 'jquery'
 
  //记录是否悬浮在指定单元格上
  let isHoverCell = false;
  //记录悬浮位置考勤记录对象
  let hoverData = null;
  //右击菜单Dom对象
  let MenuBox = null;
  //记录上一个数据的ID,用于判断是否需要新打开一个窗口
  let tmpPreId = 0;
 
  export default {
    data(){
      return {
        tableData: [],
        tableColumn: [
            {prop: "name", name: "姓名", width: "80px"},
            {prop: "workday", name: "实际到岗/天", width: "100px"},
        ]
      }
    },
    created() {
      this.updateList();
 
      //右击菜单事件
      window.oncontextmenu = function(e){
        if(isHoverCell){
          //取消默认的浏览器自带右键
          e.preventDefault();
        }
      }
      //event end
    },
    methods: {
      //...
      //end
    }
  }
</script>

绑定oncontextmenu事件后,当鼠标悬浮在考勤记录上时,则变量isHoverCell值为true,此时右击禁用则会生效。

5.2 判断鼠标位置

在methods中新建cellAddEvent()函数,将其放到updateList()函数执行结束位置,延迟100秒再执行,以防数据未渲染完jquery无法查询到全部考勤记录的DOM节点。

另外,考勤数据会因增删改查等操作,重新渲染,所以每个单元格绑定事件,也会在重新渲染后被释放,需渲染完后重新绑定事件,故cellAddEvent()函数应放应updateList()函数内执行。

<script>
  import DemoData from './demo.json'
  import $ from 'jquery'
 
  //记录是否悬浮在指定单元格上
  let isHoverCell = false;
  //记录悬浮位置考勤记录对象
  let hoverData = null;
  //右击菜单Dom对象
  let MenuBox = null;
  //记录上一个数据的ID,用于判断是否需要新打开一个窗口
  let tmpPreId = 0;
 
  export default {
    data(){
      return {
        tableData: [],
        tableColumn: [
            {prop: "name", name: "姓名", width: "80px"},
            {prop: "workday", name: "实际到岗/天", width: "100px"},
        ]
      }
    },
    created() {
      this.updateList();
 
      //右击菜单事件
      window.oncontextmenu = function(e){
        if(isHoverCell){
          //取消默认的浏览器自带右键
          e.preventDefault();
        }
      }
      //event end
    },
    methods: {
      /**
       * 为考勤记录添加相应监听事件
       */
      cellAddEvent(){
        let that = this,
            propData = "";
        //悬浮事件
        $('.date-cell').hover(function(){
          isHoverCell = true;
 
          let id = $(this).data('id'),
              filterData = DemoData.filter(item => item.id == id);
 
          if(filterData.length==1){
            hoverData = {
              prop: $(this).data('prop'),
              data: filterData[0]
            }
          }
          //if end
        }, function(){
          isHoverCell = false;
          hoverData = null;
        });
 
      },
      //加载列表数据
      updateList(){
        //获取日期列表
        let dateColumn = [],
            employeeList = [];
 
        //循环获取唯一 列日期 和 唯一 员工信息
        DemoData.map(item => {
          if(!dateColumn.includes(item.recorddate)){
            dateColumn.push(item.recorddate);
          }
          if(!employeeList.includes(item.name)){
            employeeList.push(item.name);
          }
        });
        //升序排序
        dateColumn.sort();
        //修改列长度,以免name和workday固定列被替换
        this.tableColumn.length = 2;
        //追加列
        this.tableColumn = this.tableColumn.concat(dateColumn.map(item => {
          return {
            prop: item,
            name: item,
            width: "100px",
            isDate: true
          }
        }));
 
        //重组员工考勤数据,一行显示考勤记录
        this.tableData = employeeList.map(item => {
          let nData = {},
              tmp = null,
              realWorkSize = 0;
 
          //获取对应员工的考勤记录
          dateColumn.forEach(key => {
            tmp = DemoData.filter(sub => sub.name == item && sub.recorddate == key);
            if(tmp.length==1&&tmp[0]['record'].length==2){
              //记录考勤数据
              nData[key] = tmp[0]['record'][0] + '<br />' + tmp[0]['record'][1];
              //保存对应考勤记录的ID
              nData['id_'+key] = tmp[0]['id'];
              //统计到岗天数
              realWorkSize++;
            }else{
              nData[key] = '-';
            }
          })
 
          return {
           name: item,
           workday: realWorkSize,
           ...nData
          }
        });
 
        setTimeout(() => {
          this.cellAddEvent();
        }, 100);
      }
      //end
    }
  }
</script>

此时大家会发现,鼠标在页面其他位置可以正常右击显示默认菜单,但放到考勤记录上时,右击菜单则失效无法显示了。

5.3 添加自定义菜单

当变量isHoverCell为true时,右击执行rightMenuInitial()函数,通过jquery创建菜单容器后,追加到body中。此时右击则能看到删除按钮了。

<script> 
  import DemoData from './demo.json'
  import $ from 'jquery'
 
  //记录是否悬浮在指定单元格上
  let isHoverCell = false;
  //记录悬浮位置考勤记录对象
  let hoverData = null;
  //右击菜单Dom对象
  let MenuBox = null;
  //记录上一个数据的ID,用于判断是否需要新打开一个窗口
  let tmpPreId = 0;
 
  export default {
    data(){
      return {
        tableData: [],

        ]
      }
    },
    created() {
      this.updateList();
      
      let that = this;

        tmpPreId = hoverData.data.id;
 
        //创建右击菜单容器

        $('body').append(MenuBox);
      },
      
      //...
      //end
    }
  }
</script>

5.4 增加移除菜单功能

增加removeMenuBox()函数,用于在不同情况下,需要移除自定义菜单。代码如下:

<script>
  import DemoData from './demo.json'
  import $ from 'jquery'
 
  //记录是否悬浮在指定单元格上
  let isHoverCell = false;
  //记录悬浮位置考勤记录对象
  let hoverData = null;
  //右击菜单Dom对象
  let MenuBox = null;
  //记录上一个数据的ID,用于判断是否需要新打开一个窗口
  let tmpPreId = 0;
 
  export default {
    data(){
      return {
        tableData: [],
        tableColumn: [
            {prop: "name", name: "姓名", width: "80px"},
            {prop: "workday", name: "实际到岗/天", width: "100px"},
        ]
      }
    },
    created() {
      this.updateList();
 
      let that = this;
      //右击菜单事件
      window.oncontextmenu = function(e){
        if(isHoverCell){
          //取消默认的浏览器自带右键
          e.preventDefault();
 
          that.rightMenuInitial(e);
        }
      }
      //event end
    },
    methods: {
      /**
       * 删除右击菜单
       * @date 2023/1/30
       */
      removeMenuBox(){
        if(!MenuBox) return;
        MenuBox.remove();
        MenuBox = null;
      },
      /**
       * 右击初始化弹框事件
       * @param e 右击事件
       */
      rightMenuInitial(e){
        if(null==hoverData||'undefined'===typeof hoverData.data){
          this.$message.info("数据读取失败,刷新后再试~");
          return;
        }
 
        if(null!=MenuBox) {
          this.removeMenuBox();
          //上一个右击区域未变化,则结束后续操作
          if(tmpPreId==hoverData.data.id) return;
        };
 
        //记录当前ID
        tmpPreId = hoverData.data.id;
 
        //创建右击菜单容器
        MenuBox = $('<div />').addClass('menu-box');
 
        let that = this,
            listData = [
              {id: 1, name: "删除", style: "delete"}
            ],
            ulBox = $('<ul />').addClass('list');
 
        //添加列表
        MenuBox.append(ulBox);
 
        //循环生成右击菜单列表
        for(var i in listData){
          ulBox.append($('<li />').text(listData[i]['name']).addClass(listData[i]['style']));
        }
        //for end
 
        //添加位置
        MenuBox.css({
          'position': 'absolute',
          'left': e.clientX,
          'top': e.clientY,
          'z-index': 10
        });
        //自定义菜单悬浮事件监听
        ulBox.hover(function(){
          isHoverCell = true;
        }, function(){
          isHoverCell = false;
        });
 
        /**
         * 添加删除事件
         */
        ulBox.on('click', 'li.delete', function(){
          that.$confirm('确定删除'+ hoverData.data.name + '的' + hoverData.prop+'考勤记录吗?', '提示', {
            confirmButtonText: '确定',
            cancelButtonText: '取消',
            type: 'warning'
          }).then(() => {
            //查询源数据对应位置,将其删除(这里Demo演示,真实环境需要将删除数据ID传给后台进行操作)
            let index = DemoData.indexOf(hoverData.data);
            DemoData.splice(index, 1);
 
            that.removeMenuBox();
            that.updateList();
          }).catch(() => {
            that.removeMenuBox();
            that.$message({
              type: 'info',
              message: '已取消删除'
            });
          });
        });
 
        //追加到页面中
        $('body').append(MenuBox);
      },
      /**
       * 为考勤记录添加相应监听事件
       */
      cellAddEvent(){
        let that = this,
            propData = "";
        //悬浮事件
        $('.date-cell').hover(function(){
          isHoverCell = true;
 
          let id = $(this).data('id'),
              filterData = DemoData.filter(item => item.id == id);
 
          if(filterData.length==1){
            hoverData = {
              prop: $(this).data('prop'),
              data: filterData[0]
            }
          }
          // console.log('id', id);e
          //if end
        }, function(){
          isHoverCell = false;
        });
 
        //鼠标移出事件,关闭删除菜单
        $(document).off('click').on('click', function(){

      },
      //加载列表数据
      updateList(){
        //获取日期列表
        let dateColumn = [],
            employeeList = [];
 
        //循环获取唯一 列日期 和 唯一 员工信息
        DemoData.map(item => {
          if(!dateColumn.includes(item.recorddate)){
            dateColumn.push(item.recorddate);
          }
          if(!employeeList.includes(item.name)){
            employeeList.push(item.name);
          }
        });
        //升序排序
        dateColumn.sort();
        //修改列长度,以免name和workday固定列被替换
        this.tableColumn.length = 2;
        //追加列
        this.tableColumn = this.tableColumn.concat(dateColumn.map(item => {
          return {
            prop: item,
            name: item,
            width: "100px",
            isDate: true
          }
        }));
 
        //重组员工考勤数据,一行显示考勤记录
        this.tableData = employeeList.map(item => {
          let nData = {},
              tmp = null,
              realWorkSize = 0;
 
          //获取对应员工的考勤记录
          dateColumn.forEach(key => {
            tmp = DemoData.filter(sub => sub.name == item && sub.recorddate == key);
            if(tmp.length==1&&tmp[0]['record'].length==2){
              //记录考勤数据
              nData[key] = tmp[0]['record'][0] + '<br />' + tmp[0]['record'][1];
              //保存对应考勤记录的ID
              nData['id_'+key] = tmp[0]['id'];
              //统计到岗天数
              realWorkSize++;
            }else{
              nData[key] = '-';
            }
          })
 
          return {
           name: item,
           workday: realWorkSize,
           ...nData
          }
        });
 
        setTimeout(() => {
          this.cellAddEvent();
        }, 100);
      }
      //end
    }
  }
</script>

5.5 追加菜单内容

在自定义右击菜单时,已预留了增加更多菜单项位置,如下代码,在变量listData中添加菜单内容即可。

rightMenuInitial(e){
    if(null==hoverData||'undefined'===typeof hoverData.data){
      this.$message.info("数据读取失败,刷新后再试~");
      return;
    }
 
    if(null!=MenuBox) {
      this.removeMenuBox();
      //上一个右击区域未变化,则结束后续操作
      if(tmpPreId==hoverData.data.id) return;
    };
 
    //记录当前ID
    tmpPreId = hoverData.data.id;
 
    //创建右击菜单容器
    MenuBox = $('<div />').addClass('menu-box');
 
    let that = this,
        listData = [
          {id: 1, name: "编辑", style: "edit"},
          {id: 2, name: "删除", style: "delete"}
        ],
        ulBox = $('<ul />').addClass('list');
    //...
}

如下图,右击时自定义菜单中则出现“编辑”项了,这块功能这里就不作详解,大家可以自行操作。这里就简单讲解下自定义右击菜单和删除功能,仅供大家参考,如有不足之处请见谅!
