How do I escape an HTML snippet generated by a template? Like in this example:
package main
import (
"fmt"
"html/template"
"os"
)
// I want to escape a html snippet which is then stored as a
// javascript variable. how can I do that? the second output
// is the one i would like to generate with a template.
var tmpl = `{{define "main"}}<script>var xx = "{{template "html-snippet" .}}";</script>{{end}}{{define "html-snippet"}}<div>
<img src="{{.}}">
</div>{{end}}`
func main() {
t, err := template.New("fo").Parse(tmpl)
if err != nil {
fmt.Println(err)
return
}
t.ExecuteTemplate(os.Stdout, "main", "some.jpg")
fmt.Println("")
fmt.Println(template.JSEscapeString(`<div>
<img src="some.jpg">
</div`))
}

html/template
does not do it automatically in my case. JSEscapeString
through a func map also does not work (or I don’t know how), because I cannot call it like this {{jsescape (template "html-snippet" .)}}
, since this is not a string.
Many thanks
