这是完整的工作示例。
// home.html inside temps folder{{define "homeHTML"}}{{template "headHTML" .}}{{template "headerHTML" .}}{{template "footerHTML" .}}{{end}}// head.html inside data folder{{define "headHTML"}}<!DOCTYPE html><html> <head> <meta charset="utf-8"> <title>{{.title}} - MySite</title> <link rel="stylesheet" type="text/css" href="style.css"> </head> {{end}}// header.html inside data folder{{define "headerHTML"}}<header> {{.header}} <h1>Welcome to my site!</h1> <br> <nav> <a href="/">Home</a> </nav></header>{{end}}// footer.html inside data folder{{define "footerHTML"}}<h1>Welcome! {{.footer}}</h1><footer><p>Thank You for Visiting</p></footer></body></html>{{end}}和代码将是这样的
