How to print JSON on golang template?

go, go-templates

Solution

In JS context normal strings always gets escaped. I should have converted to `template.JS` type before printing.

Ref: http://golang.org/pkg/html/template/#JS

This is new marshal function:

"marshal": func(v interface {}) template.JS {
  a, _ := json.Marshal(v)
  return template.JS(a)
},

Problem

I need a object in client side, so I converted it to JSON using json.marshal and printed it into template. The object is getting printed as escaped JSON string. I'm expecting it to be `var arr=["o1","o2"]` but it is `var arr="[\"o1\",\"o2\"]"` I know I can JSON.parse in client side, but is that the only way? Here is how I'm printing it in template: `{{ marshal .Arr }}` Here is my marshal function: ``` "marshal": func(v interface {}) string { a, _ := json.Marshal(v) return string(a) }, ```
