从离子2中的动作表中获取用户输入

Question

getcode是我想从用户那里获取的值并将其传递给 getCoupon函数，然后我想将结果传递给另一个警报，并在消息属性中显示优惠券，而无需获得[object object]

showPrompt(message,offer,getcode) {
    this.peopleservice.getCoupun(offer,getcode).subscribe(data=> this.Code=data);
    let prompt = this.alertCtrl.create({
          title: 'code',
          message: message,
          inputs: [{
              name: 'Code',
              placeholder: 'code',
          }],
          buttons: [{
               text: 'Cancel',
               handler: data => {
               console.log('Cancel clicked');
          }
        },{
           text: 'ok',
           handler: data => {
                this.Coupun();
          }
        }
     Coupun(){
        let prompt = 
            this.alertCtrl.create({
                 title: ' code ',
                 message:"the result for the getCoupun request",
                 buttons:[{
                    text: 'Cancel',
                    handler: data => {
                        console.log('Cancel'); 
                        }
                     }]
            });
            prompt.present();
     }

实现的步骤

1. 安装Cordova动作表插件

2. 在控制器中

   `import {component}来自'@angular/core'; 从'ionic-angular'导入{navController，navParams}; 导入{ActionSheet，ActionSheetOptions}来自'@ionic-native/action-sheet'; 令ButtonLabelStoshow = ['通过Facebook共享'，'通过Twitter共享']; @成分({ 选择器：'Page-Action-Demo'， TemplateUrl：" Action-sheet-demo.html"， }(( 导出类ActionsHeetDemopage {
   /**操作表选项*/ 选项：ActionSheetOptions = { 标题："与世界分享此图像"， 字幕："从各种选项中选择"， 纽扣标签：ButtonLabelStoshow， AddCancelButtonWithLabel："取消"， addStrestiveButtonWithlabel：'delete'， DestructiveButtonLast：是的 }

   constructor(private actionSheet: ActionSheet, public navCtrl: NavController, public navParams: NavParams) {
   }
   ionViewDidLoad() {
     console.log('ionViewDidLoad ActionSheetDemoPage');
   }
   openActionSheet() {
     this.actionSheet.show(this.options).then((buttonClickedIndex: number) => {
       console.log('Button pressed is' + buttonClickedIndex)
     }).catch((err) => {
       console.log(err)
     });
   }
   

   }`

   3.in模板<button ion-button (click)="openActionSheet()">Button</button>
