Question

我正在使用Vue的列表渲染创建单选按钮，我希望有一个预选的值，但脚本中没有数据集。

请参见以下代码，以更好地低估我要实现的目标：

脚本：

func displayAnnotations() {

        let ref = Database.database().reference()
        ref.child("Postbox").observe(.childAdded, with: { (snapshot) in

            let monToFri = (snapshot.value as AnyObject?)!["Monday to Friday Collection Time"] as! String?
            let sat = (snapshot.value as AnyObject?)!["Saturday Collection Time"] as! String?
            let latitude = (snapshot.value as AnyObject?)!["Latitude"] as! String?
            let longitude = (snapshot.value as AnyObject?)!["Longitude"] as! String?

            let lastCollection = "Mon - Fri: \(monToFri!)" + " Sat:  \(sat!)"

            self.annotation.coordinate = CLLocationCoordinate2D(latitude: (Double(latitude!))!, longitude: (Double(longitude!))!)
            self.annotation.title = "Last Collection:"
            self.annotation.subtitle = lastCollection

            self.mapView.addAnnotation(self.annotation)

            self.postboxesLoggedLabel.text = String(self.mapView.annotations.count)

        })

    }

模板：

data() {
   return {
       formData: {} //formData is empty by default, properties added on fly
   }
}

是否可以通过JavaScript实现此目标？

您可以将初始状态设置为租金，如下所示：

get root node..
org.apache.jackrabbit.rmi.client.RemoteRepositoryException:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.io.InvalidClassException: org.apache.jackrabbit.rmi.value.StringValue; local class incompatible: stream classdesc serialVersionUID = -6456025645604163205, local class serialVersionUID = 220963478492833703

然后当您迭代更改为：

data (
    return {
        formData : {
            Department: "rent"
        }
    }
)

是否可以在VUE中检查电台而不污染数据？
