Q:

Html template use on golang

Sorry im beginner and i read golang.docs but didnt understand well.
i`ve :   index.html:
<html>
<head>
</head>
<body>
<form action type="checkbox" name="test" value="A" {{.checked}}>
<input type="submit" value="save">
</body>
</html>

in main.go
   if user click save button then check checkbox redirect that page and show checkbox checked

A:

You could send variables in map. For example: 
package main

import (
    "bytes"
    "fmt"
    "text/template"
)

func main() {
    t, _ := template.New("hi").Parse("Hi {{.name}}")
    var doc bytes.Buffer
    t.Execute(&doc, map[string]string{"name": "Peter"})
    fmt.Println(doc.String()) //Hi Peter
}
