Append to slice of struct
Implement append, to a slice of structs.
Page content
Lets append more values to a slice of struct, or an array of struct
Append values to a slice
type Key struct {
Name string
}
type Keyboard struct {
Keys []Key
}
func (kboard *Keyboard) AddKey(k Key) []Key {
kboard.Keys = append(kboard.Keys, k)
return kboard.Keys
}
func main() {
// myKey1 := Key{Name: "Test Key 1", Role: "Upper"}
myKey1 := Key{Name: "Test Key 1"}
myKeyboard := Keyboard{}
myKeyboard.AddKey(myKey1)
myKeyboard.AddKey(Key{Name: "Test Key 2"})
fmt.Println(len(myKeyboard.Keys))
fmt.Println(myKeyboard.Keys)
}
To print out
2
[{Test Key 1 } {Test Key 2 }]
Append values to an array
type Key struct {
Name string
}
type EnKeyboard struct {
Keys [5]Key
}
func (kboard *EnKeyboard) AddKeyToEn(k Key) []Key {
for i, v := range kboard.Keys {
if v.Name == "" || len(v.Name) < 1 {
kboard.Keys[i] = k
return kboard.Keys[:]
}
}
return kboard.Keys[:]
}
func main (){
func main() {
myKey1 := Key{Name: "En Key 1"}
myEnKeyboard := EnKeyboard{}
myEnKeyboard.AddKeyToEn(myKey1)
myEnKeyboard.AddKeyToEn(Key{Name: "En Key 2"})
fmt.Println(len(myEnKeyboard.Keys))
fmt.Println(myEnKeyboard.Keys)
}
5
[{En Key 1} {En Key 2} {} {} {}]
