如何使用ng for in顯示詳細信息2

Question

我在做我的項目中的感謝頁面。在成功調用它會顯示順序的細節和物流詳情&失敗呼叫只會顯示訂購詳細..

成功調用工作正常，但故障電話不顯示訂單詳細信息...

下面

是我的html代碼..

下面

是我的TS文件...

import { Component } from '@angular/core'; 

import { NavController } from 'ionic-angular'; 

import { Rest } from '../../providers/network/rest'; 

import { Logger } from '../../providers/logger/logger'; 



/* 
    Generated class for the ThankYou page. 

    See http://ionicframework.com/docs/v2/components/#navigation for more info on 
    Ionic pages and navigation. 
*/ 
@Component({ 
    selector: 'page-thank-you', 
    templateUrl: 'thank-you.html' 
}) 
export class ThankYouPage { 

    orderDetailsArray = []; 

    public orderSuccess:boolean =false; 

    public orderFailure:boolean =false; 

    constructor(public navCtrl: NavController, 
       public rest: Rest, 
       public logger: Logger) {} 

    ionViewDidLoad() { 

    this.rest.get('/getOrder&order_id=0') 
    .subscribe((result) => { 
     console.log("checking getOrder"+JSON.stringify(result)); 
     if(result.status == '1'){ 
      console.log("success of getOrder"); 
      this.orderDetailsArray=result.order; 
      this.orderSuccess=true;  
     } 

     else{ 
      console.log("error of getOrder"); 
      this.orderFailure = true; 
     } 

    }) 
    } 

    submit(){ 
     //this.navCtrl.setRoot(HomePage,{}); 
    } 
    notSubmit(){ 
     //this.navCtrl.push(PaymentPage,{}); 
    } 

} 

成功調用工作正常，但故障呼叫不是DIS玩下單細節...

Answer 1

這是因爲你只設置orderDetailsArray如果你的result.status是1！

你應該做的是這樣的：

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

你也可以用它來result.status轉換成Integer.Try這是因爲狀態應該總是以整數類型，你正在使用string.I希望會幫助你。

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