如何检查哪个动态按钮被触摸

Question

我已在angular 6中创建了动态按钮。如何找出打字稿中触摸了哪个按钮。

assigndynamicfields() {

    setTimeout(() => {

      this.getRecord();

      //call service and assign dynamic config data
      this.fieldsData.push({
        name: "save",
        type: "button",
        label: "Save"
      },
        {
          name: "delete",
          type: "button",
          label: "Delete"
        }
      )
        ;
      this.regConfig = this.fieldsData;
      this.form = DynamicFormComponent;

    }, 500)
  }
