React：tabs或标签页自定义右击菜单内容，支持内嵌iframe关闭菜单方案

不管是react、vue还是原生js，原理是一样的。
注意如果内嵌iframe情况下，iframe无法使用事件监听，但是可以使用iframe的任何点击行为都会往父级window通信，使用window的message事件监听即可。

场景

前端自定义标签页，一个标签对应一个路由页面，通过切换标签快速切换不同应用或者页面

代码

变量

state = {
    contextMenuIndex: '', // 右击菜单索引
    contextMenuPosition: { // 右击菜单定位信息
      clientX: '',
      clientY: '',
    },
    visiableContextMenu: false, // 右击菜单是否显示
  };

事件加载

componentDidMount() {
	// 监听当前document的鼠标右击事件
    document.addEventListener('contextmenu', (event) => {
      event.preventDefault();
      if (this.state.visiableContextMenu === -1) {
        return;
      }
      this.setState({
        contextMenuPosition: {
          clientX: `${event.clientX}px`,
          clientY: `${event.clientY}px`,
        },
      });
    });
    
	// 监听当前document的鼠标点击事件，用于关闭自定义菜单
    document.addEventListener('click', () => {
      this.setState({
        visiableContextMenu: false,
      });
    });

	// 监听当前window的messag事件（有内嵌iframe时使用，若无可不使用）
	// 无法使用iframe监听，可以通过和父级window的消息通信达到目的。
    window.addEventListener('message', () => {
      this.setState({
        visiableContextMenu: false,
      });
    });
  }

标签

		<div>
		  {/* ... */}

		  {/* 自定义右击菜单 */}
          {visiableContextMenu ? (
            <Menu
              className="contextMenuList"
              style={{ left: clientX, top: clientY }}
            >
              <Menu.Item onClick={() => this.hadleCloseByIndex([contextMenuIndex])}>
                关闭当前
              </Menu.Item>
              <Menu.Item onClick={() => this.closeLeft()}>关闭左侧</Menu.Item>
              <Menu.Item onClick={() => this.closeRight()}>关闭右侧</Menu.Item>
              <Menu.Item onClick={() => this.closeAll()}>关闭全部</Menu.Item>
            </Menu>
          ) : (
            ''
          )}
        </div>
