Go尋找slice中物件元素。
範例環境:
- Go 1.19
例如以名稱尋找Department.Employees
slice中的struct Employee
元素。
main.go
package main
import "fmt"
type Department struct {
Employees []Employee
}
type Employee struct {
ID int
Name string
}
func (dep *Department) FindEmployee(name string) *Employee {
for _, v := range dep.Employees {
if v.Name == name {
return &v
}
}
return nil
}
func main() {
dep := Department{
Employees: []Employee{
{1, "John"},
{2, "Mary"},
{3, "Tony"},
},
}
fmt.Println(dep.FindEmployee("Mary").ID) // 2
}
