  ]
}
layoutData.json

 运行起来之后,页面效果

    加上点背景颜色

.vue-grid-item {
  background: aquamarine;
}

  

 

  此时可以拖拽,可以改变格子大小了。

  接下来开始写几个方法,封装一下配置

  

添加右键事件,以后配置的时候用

  html:

  <ul class='contextmenu' v-show="menuConfig.visible" :style="{left:menuConfig.left+'px',top:menuConfig.top+'px'}">
      <li @click="test(1)">1</li>
      <li @click="test(2)">2</li>
      <li @click="test(3)">3</li>
    </ul>
  script:
 <data>
        menuConfig: {
          visible: false,
          left: 0,
          top: 0
        }
    <methods>
      // 右键打开菜单
      openMenu(tag, e) {
        this.menuConfig.visible = true
        this.menuConfig.left = e.clientX
        this.menuConfig.top = e.clientY
      },
      // 关闭菜单
      closeMenu() {
        this.menuConfig.visible = false
      },
      // 测试方法
      test(i) {
        console.log(i)
      }
    },  
<watch>
// 点击任意处,关闭菜单
 'menuConfig.visible'() {
        if (this.menuConfig.visible) {
          document.body.addEventListener('click', this.closeMenu)
        } else {
          document.body.removeEventListener('click', this.closeMenu)
        }
      }
View Code

   style:

   .contextmenu {
      margin: 0;
      background: #fff;
      z-index: 100;
      position: absolute;
      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, .3);
      li {
        margin: 0;
        padding: 7px 16px;
        cursor: pointer;
        &:hover {
          background: #eee;
        }
      }
    }
