In VIEW, javascript is as follow:

   var obj = JSON.stringify('@Model.CollegeInformationlist');
   alert(obj[1].State);  //NOT WORKING, giving string char

      $.each('@Model.CollegeInformationlist', function (i, item) {

    var r = $.parseJSON(obj);
    alert(r.State);    //just giving undefined.
    });

Please guide here, how i can get JSON object in javascript.

Answer 1

You could use the following:

var json = @Html.Raw(Json.Encode(@Model.CollegeInformationlist));

This would output the following (without seeing your model I've only included one field):

<script>
    var json = [{"State":"a state"}];   
</script>

Working Fiddle

AspNetCore

AspNetCore uses Json.Serialize intead of Json.Encode

var json = @Html.Raw(Json.Serialize(@Model.CollegeInformationlist));

MVC 5/6

You can use Newtonsoft for this:

    @Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(Model, 
Newtonsoft.Json.Formatting.Indented))

This gives you more control of the json formatting i.e. indenting as above, camelcasing etc.
