In VIEW, javascript is as follow:

   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.

回答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.

If You want make json object from yor model do like this :

  foreach (var item in Persons)
   {
    var jsonObj=["FirstName":"@item.FirstName"]
   }

Or Use Json.Net to make json from your model :

string json = JsonConvert.SerializeObject(person);

After use codevar json = @Html.Raw(Json.Encode(@Model.CollegeInformationlist));

You need use JSON.parse(JSON.stringify(json));

回答4:

In ASP.NET Core the IJsonHelper.Serialize() returns IHtmlContent so you don't need to wrap it with a call to Html.Raw().

It should be as simple as:

<script>
  var json = @Json.Serialize(Model.CollegeInformationlist);
</script>

回答5:

Pass the object from controller to view, convert it to markup without encoding, and parse it to json.

@model IEnumerable<CollegeInformationDTO>

@section Scripts{
    <script>
          var jsArray = JSON.parse('@Html.Raw(Json.Encode(@Model))');
    </script>
}
