{{define "header"}}<!doctype html><html lang="en"><head><meta charset="utf-8"><title>{{.Title}}</title></head><body><h1>Header template</h1><div>{{.FooterField}}</div>{{end}}
index.html
{{define "index"}}{{template "header" . }}
<h1>Index template</h1>
<div>{{.FooterField}}</div>
{{template "footer"}}{{end}}
{{define "footer"}}<h1>Footer template</h1>
Missing FooterField->{{.FooterField}}</body></html>{{end}}
最后是浏览器中的输出http://localhost:8085/
Header template
This text does not appear in the footer template
Index template
This text does not appear in the footer template
Footer template
Missing FooterField->
