I am having a problem to properly escape javascript urls in my templates. I
do have the situation where I build a template that is having javascript
urls that are from variables in the go program (read from yaml files). The
go program generates static html, but the html is supposed to use
moustache.js to expand some further variables at render time. I am just not
able to preserve my javascript from the html/template escaping. Any ideas
what I am doing wrong?
The output is:
<a href="javascript:doSlide%28%27%7b%7barea%7d%7d%27%29;">{{test}}</a>
But I would like it to be:
<a href="javascript:doSlide('{{area}}');">{{test}}</a>
package main
import (
"html/template"
"os"
)
var t = template.Must(template.New("test").Funcs(template.FuncMap{
"safeattr": func(value string) template.HTMLAttr {
return template.HTMLAttr(value)
},
"safehtml": func(value string) template.HTML {
return template.HTML(value)
},
"safejs": func(value string) template.JS {
return template.JS(value)
},
"safecss": func(value string) template.CSS {
return template.CSS(value)
},
"safeurl": func(value string) template.URL {
return template.URL(value)
},
}).Parse(`
<a href="{{safeurl .href}}">{{safehtml .content}}</a>
`))
func main() {
data := map[string]string{
"href": "javascript:doSlide('{{area}}');",
"content": "{{test}}",
}
err := t.Execute(os.Stdout, data)
if err != nil {
panic(err)
}
}
