我要说的是:
type Person struct {
Name string
}
func (p *Person) Label() string {
return "This is " + p.Name
}
我如何从html/template处使用这种方法? 在我的模板中,我需要这样一些:
{{ .Label() }}
我要说的是:

仅指母体,应予罚款。 例:
package main
import (
"html/template"
"log"
"os"
)
type Person string
func (p Person) Label() string {
return "This is " + string(p)
}
func main() {
tmpl, err := template.New("").Parse(`{{.Label}}`)
if err != nil {
log.Fatalf("Parse: %v", err)
}
tmpl.Execute(os.Stdout, Person("Bob"))
}
根据文件,如果第二个数值为
你们甚至能够通过如下参数来发挥职能:
type Person struct {
Name string
}
func (p *Person) Label(param1 string) string {
return "This is " + p.Name + " - " + param1
}
然后在模板中书写
{{with person}}
{{ .Label "value1"}}
{{end}}
假设该模板中的人是一种变式的变体。
如果我不称职,或最近对戈模板进行了修改,但我无法利用关于数据结构的职能。 浏览器收到“can t评价外地
误差”。
我得以通过使用FuncMap
。
Example:
temp := template.New("templatename.gohtml")
temp.Funcs(
template.FuncMap{
"label": Label,
},
)
temp, err := temp.ParseFiles(
"templatename.gohtml",
)
if err != nil {
log.Fatal("Error parsing template", err)
}
err = temp.Execute(os.Stdout, nil)
模板:
{{label "the label"}}
Label func:
func Label(param string) string {
...
}
What is the difference between Go s multithreading approach and other approaches, such as pthread, boost::thread or Java Threads?
Does anyone know approximately what the minimum work size is needed in order for a goroutine to be beneficial (assuming that there are free cores for the work to be offloaded to)?
How do I get the terminal size in Go. In C it would look like this: struct ttysize ts; ioctl(0, TIOCGWINSZ, &ts); But how to i access TIOCGWINSZ in Go
I know its a bit too early, but I ve been trying out Go (Google s Programming Language) and its kindof annoying to write code in gedit. So, my question: What do you use to experiment with Go?
All the examples I ve seen so far involve blocking to get the result (via the <-chan operator). My current approach involves passing a pointer to a struct: type goresult struct { result ...
One of Go s slogans is Do not communicate by sharing memory; instead, share memory by communicating. I am wondering whether Go allows two different Go-compiled binaries running on the same machine to ...
