的錯誤,當我運行下面的代碼 -捕獲entity.entityAspect.entityManager.createEntity
this.entity.entityAspect.entityManager.createEntity('TblReceipt', {
ReceiptNo : 123
....
});
代碼罰款第一次運行時並創建新的實體。現在,當用戶試圖再次運行它給出以下錯誤 -
Uncaught Error: A MergeStrategy of 'Disallowed' does not allow you to attach an entity when an entity with the same key is already attached"
上述錯誤顯示在控制檯中。如何在JavaScript代碼中捕獲此錯誤並向用戶顯示消息?
謝謝
