我正在使用响应式表(sap.m.Table),我想知道当单击表上的Delete按钮时如何在控制器中获取行值。我正在尝试在函数onGaDelete和onGakDelete中获取行值。

这是我的查看代码。

});

预期结果是在控制器中获取行值。

delete api事件提供了"listItem"参数,通过该参数我们可以获取被单击的项目控件以及通过其上下文绑定的数据。例如:

<Table xmlns="sap.m"
  mode="Delete"
  delete=".onItemDelete"
>
  <!-- ... -->
</Table>
onItemDelete: function(event) {
  const itemToDelete = event.getParameter("listItem"); // clicked ColumnListItem
  const context = itemToDelete.getBindingContext(/*modelName*/);
  // get row values via context.getProperty(<propertyName>); E.g.:
  const boundId = context.getProperty("ID");
  // or get the whole object:
  const boundObject = context.getObject(); // returns {ID: "...", ...}
},
