I have a template in go using the http/template package. How do I iterate over both the keys and values in the template?
Example code :
template := `
<html>
<body>
<h1>Test Match</h1>
<ul>
{{range .}}
<li> {{.}} </li>
{{end}}
</ul>
</body>
</html>`
dataMap["SOMETHING"] = 124
dataMap["Something else"] = 125
t, _ := template.Parse(template)
t.Execute(w,dataMap)
How do I access the key in {{range}} in the template
One thing you could try is using range to assign two variables - one for the key, one for the value. Per this change (and the docs), the keys are returned in sorted order where possible. Here is an example using your data:
package main
import (
"html/template"
"os"
)
func main() {
// Here we basically 'unpack' the map into a key and a value
tem := `
<html>
<body>
<h1>Test Match</h1>
<ul>
{{range $k, $v := . }}
<li> {{$k}} : {{$v}} </li>
{{end}}
</ul>
</body>
</html>`
// Create the map and add some data
dataMap := make(map[string]int)
dataMap["something"] = 124
dataMap["Something else"] = 125
// Create the new template, parse and add the map
t := template.New("My Template")
t, _ = t.Parse(tem)
t.Execute(os.Stdout, dataMap)
}
There are likely better ways of handling it, but this has worked in my (very simple) use cases :)
