    <h-button class="button-class" type="rimless" shadow @click.native="showNotifyAtBottom">Notify (bottom)</h-button>
    
    
    // 标签用法
    showNotifyAtTop() {
      if (this.show1) return
         this.show1 = true
      },
    showNotifyAtBottom() {
      if (this.show2) return
         this.show2 = true

              position: ops.position,
              time: ops.time
            })

          handleNotify() {
            this.showNotify({
