當我嘗試在Ionic 2中使用基本警報提示警報時卡住

Question

我的問題v.simple但我無法找到解決方案。我試圖在提示警報內顯示基本警報以顯示我輸入的結果，但我不知道爲什麼我的應用程序卡住了。

這是基本的例子對我的代碼和它的卡住時，「重複的電子郵件」警報顯示，當我OK按鈕點擊使用「超時」

let prompt = this.alertCtrl.create({ 
title: 'Replacement Email', 
message: "Please enter your new email", 
inputs: [{ 
    type: 'email', 
name: 'email', 
placeholder: 'user1@gmail.com' 
}, 
], 
buttons: [ 
    { 
    text: 'Cancel', 
    handler: data => { 
     console.log('Cancel clicked'); 
    } 
    },{ 
    text: 'Save', 
    handler: data => { 
     if(data.email!=""){ 
     if(data.email==this.userService.email){ 
      let alert = this.alertCtrl.create({ 
       title: "Duplicated email", 
       subTitle: "Please enter new email", 
       buttons: ['OK'] 
      }); 
      alert.present(); 
     } 
     } 
    } 
    } 
] 
}); 
prompt.present();
