Parse model to json on gsp in grails
Posted By : Akash Sharma | 16-Feb-2014
Sometimes we have a requirement to pass data as model from controller action but we need it as a json object on gsp.
Below is the code snippet that works the same.
Let say I have a Person domain.I am passing it as a model but need it as JSON on gsp.
I am printing the converted JSON object in browser console.
Controller code
def index(){
ArrayList listOfPerson=Person.list()
[listOfPerson:listOfPerson]
}
GSP code
<%! import grails.converters.JSON %>
<html>
<head>
<meta name="layout" content="main">
<g:javascript library="jquery"></g:javascript>
</head>
<body>
<script>
function parseModelToJS(jsonString)
{
jsonString=jsonString.replace(/\"/g,'"');
var jsonObject=$.parseJSON(jsonString);
return jsonObject
}
$(document).ready(function(){
var listOfPerson=parseModelToJS('${listOfPerson as JSON}');
console.log(listOfPerson);
});
</script>
</body>
</html>
