Sending JSON to javascript on GSP

The following worked for me using Grails 2.4.3:

Controller:

def result = [:]
result['type'] = "bar"
result['data'] = [5, 20, 45]

model: [data: result as JSON]

GSP:

<script>
// this worked!
var data = ${raw(data as String)};
</script>

Produced desired result:

<script>
// this worked!
var data = {"type":"bar","data":[5,20,45]};
</script>

The accepted answer by Dónal DID NOT work for me:

Controller (same as my working example above)

GSP (did NOT work):

<script>
// did NOT work!!
var data = ${raw(data)};
</script>

Produced same bad result:

<script>
// did NOT work!!
var data = {&quot;type&quot;:&quot;bar&quot;,&quot;data&quot;:[5,20,45]};
</script>

The encodeAsJSON() method works well for outputting JSON data into JavaScript:

Controller

def testData() {
   def data = [name: "Sales", values: [5, 20, 45]]
   [data: data]
   }

View (GSP)

<script>
var data1 = ${raw(data)};  //{name=Sales, values=[5, 20, 45]}
var data2 = ${raw(data as grails.converters.JSON)};  //{&quot;name&quot;:&quot;Sales...
var data3 = ${data.encodeAsJSON()};  //{"name":"Sales","values":[5,20,45]}  CORRECT!
</script>

Using raw() on a Groovy object does not produce JavaScript compatible output (see data1), and using it after the JSON converter results in unwanted " encoding (see data2). Using encodeAsJSON() produces the correct output (see data3).

Update:
I've switched to using a taglib with:

out << "<script>const data = " + raw((data as JSON) as String) + ";</script>"

The problem is that the JSON is being encoded as HTML. Try the following instead:

Controller

def testData() {
    def result = [:]
    result['name'] = "Sales"
    result['type'] = "bar"
    result['data'] = [5, 20, 45, 10, 10, 20]
    [data: result as JSON]
}

GSP

<script>
    var data = ${raw(data)};
</script>

You don't need $(document).ready because the JS code

var data = ${raw(data)};

is generated on the server-side

Working solution :

def action() {
  [data: data as JSON]
}

GSP page:

<g:applyCodec encodeAs="none">
    var data = ${data};
</g:applyCodec>
