对于Go结构体中的默认值，我们使用匿名结构:

Person := struct {
    name      string
    age       int
    city      string
}{
    name:      "Peter",
    age:        21,
    city:      "Noida",
}

fmt.Println(人)

一种可能的想法是编写单独的构造函数

//Something is the structure we work with
type Something struct {
     Text string 
     DefaultText string 
} 
// NewSomething create new instance of Something
func NewSomething(text string) Something {
   something := Something{}
   something.Text = text
   something.DefaultText = "default text"
   return something
}

从https://golang.org/doc/effective_go.html # composite_literals:

有时0值还不够好，需要初始化构造函数，就像这个从包os派生的例子一样。

    func NewFile(fd int, name string) *File {
      if fd < 0 {
        return nil
      }
      f := new(File)
      f.fd = fd
      f.name = name
      f.dirinfo = nil
      f.nepipe = 0
      return f
}

type Config struct {
    AWSRegion                               string `default:"us-west-2"`
}

    age       int
    city      string

    age:        21,

}

做这样的东西怎么样:

// Card is the structure we work with
type Card struct {
    Html        js.Value
    DefaultText string `default:"html"` // this only works with strings
}

// Init is the main function that initiate the structure, and return it
func (c Card) Init() Card {
    c.Html = Document.Call("createElement", "div")
    return c
}

然后将其命名为:

c := new(Card).Init()
