[英]Wicket - get the selected item in the DropDownChoice using Scala
如何在ListView中通過DropDownChoice獲得所選項目?
我實現了以下代碼:
val listCustomer: java.util.List[Customer] = customerDAO.listCustomers
item.add(new DropDownChoice("customerSelection", listCustomer, new ChoiceRenderer[Customer]("name")))
在這種情況下,我要顯示模型Customer的name屬性。
謝謝
嘗試這個:
new DropDownChoice[Customer](("customerSelection", new Model[Customer], listCustomer, new ChoiceRenderer[Customer]("name"))) {
protected override def wantOnSelectionChangedNotifications: Boolean = true
protected override def onSelectionChanged(newSelection: Customer) {
super.onSelectionChanged(newSelection)
}
}
