如何在 ionic 2 中使用 ng for 显示详细信息

Question

我在我的项目中做了感谢页面。在成功调用中，它将显示 ORDER DETAILS 和 Delivery Details & Failure 调用它将仅显示 ORDER DETAILS..

成功调用正常，但失败调用不显示订单详细信息...

下面是我的html代码..

Answer 1

这是因为您仅在您的 result.status 是 1 时才设置 orderDetailsArray！

你应该这样做：

ionViewDidLoad() {
   this.rest.get('/getOrder&order_id=0')
      .subscribe((result) => {
         console.log("checking getOrder"+JSON.stringify(result));

         this.orderDetailsArray=result.order; // <-- place it here !

         if(result.status == '1') {
            console.log("success of getOrder");
            this.orderSuccess=true;      
         }
         else {
            console.log("error of getOrder");
            this.orderFailure = true;
         }
   });
}

Answer 2

您也可以使用它来将 result.status 转换为 Integer。试试这个，因为 status 应该始终为整数类型，并且您使用的是 string。希望对您有所帮助。

 if(((result.status)*1) == 1) {...}
