Go: Print each element in slice on new line with html/template
问题
如何在新行上打印"apple"、"orange"和"pear"？
GO代码：
const titlepage = `
<html>
<h1>{{ .Title}}</h1>
<h1>{{ range $i := .Body}}{{$i}}{{end}}</h1>
</html>
`
type tp struct {
Title string
Body []string
}
func Read() ([]string) {
a := []string{"apple", "orange", "pear"}
return a
}
func main() {
as := tp{Title: "Hello", Body: Read()}
t := template.Must(template.New("Tele").Parse(titlepage))
t.Execute(os.Stdout, as)
}
当前输出：
<html>
<h1>Hello</h1>
<h1>appleorangepear</h1>
</html>

<h1>appleorangepear</h1>
</html>

模板中的换行符将被复制到结果中。如果你想在{{$i}}之后换行，只需添加一个换行符。
编辑：如果你想在网页浏览器中显示换行符，你需要使用像<br/>这样的HTML元素，或者将你的项目放在<li>（列表）中。我在代码中添加了一个<br/>。
const titlepage = `
<html>
<h1>{{ .Title}}</h1>
<h1>{{ range $i := .Body}}{{$i}}<br/>
{{end}}</h1>
</html>
`
type tp struct {
Title string
Body []string
}
func Read() ([]string) {
a := []string{"apple", "orange", "pear"}
return a
}
func main() {
as := tp{Title: "Hello", Body: Read()}
t := template.Must(template.New("Tele").Parse(titlepage))
t.Execute(os.Stdout, as)
}
你可以在这里查看代码的运行结果：http://play.golang.org/p/1G0CIfhb8a
英文:
Newline characters from the template will be copied into the result. If you want a newline after {{$i}}, you just need to add one.
Edit: If you want a newline to appear in the web browser, you need to use an HTML element like <br/>, or put your items in a <li> (list). I added a <br/> to the code.
http://play.golang.org/p/1G0CIfhb8a
const titlepage = `
<html>
<h1>{{ .Title}}</h1>
<h1>{{ range $i := .Body}}{{$i}}<br/>
{{end}}</h1>
</html>
`
type tp struct {
Title string
Body []string
}
func Read() ([]string) {
a := []string{"apple", "orange", "pear"}
return a
}
func main() {
as := tp{Title: "Hello", Body: Read()}
t := template.Must(template.New("Tele").Parse(titlepage))
t.Execute(os.Stdout, as)
}
