How to prevent " from being encoded as " in Razor?

  • 772

Well the question here is that I'm working on a razor file and I want to create a json from an array in vb.netthe following way:

For Each ItineraryPnr In ItinerariesNode.ChildNodes
    arrayPnrRetrieve(contPnr) = New With {Key .trasactionId = ItineraryPnr.SelectSingleNode("TransactionId").InnerText, .isSucces = False, .provider = ItineraryPnr.SelectSingleNode("Provider").InnerText, .pnr = ItineraryPnr.SelectSingleNode("PNR").InnerText, .errors = Nothing}
    contPnr = contPnr + 1
Next

Dim serializerPnrModel As New JavaScriptSerializer()
Dim jsonPnrRQ As String = serializerPnrModel.Serialize(arrayPnrRetrieve)

The above generates something like the following and I assign it to the variable jsonPnrRQ:

[
  {
   "trasactionId":"c592360b-3d29-4689-9683-8b53b4880099",
   "isSucces":false,
   "provider":"4O",
   "pnr":"DBZD2N",
   "errors":null
  }
]

So when wanting to assign it to a variable javascriptin the following way:

 @<script>
     var metadata = {};            

     metadata.jsonEx = {};
     metadata.jsonEx.pnrRetrieve = @jsonPnrRQ;
     metadata.jsonEx.sequenceNumber = "3";

  </script>

It leaves the page cycled and sends me a syntax error, since the variable jsonPnrRQwhen debugging it is in a correct format.

The error is the following:

Uncaught SyntaxError: Unexpected token &

The question would be if anyone has happened and has a solution for this?

When printing my object Jsit shows it to me as follows

 metadata.jsonEx = {};
 metadata.jsonEx.pnrRetrieve = [{&quot;trasactionId&quot;:&quot;c592360b-3d29-4689-9683-8b53b4880099&quot;,&quot;isSucces&quot;:false,&quot;provider&quot;:&quot;4O&quot;,&quot;pnr&quot;:&quot;DBZD2N&quot;,&quot;errors&quot;:null}];
 metadata.jsonEx.sequenceNumber = "3";

And I think that may be the problem, so the other question would be, does anyone have an idea why it is assigned to me like this and how I can solve it? being that the variable jsonPnrRQhas its value well (this is because when debugging it it comes out with the correct format).

    Try the following:

    metadata.jsonEx.pnrRetrieve = @Html.Raw(jsonPnrRQ);

    The problem is that the content of the string jsonPnrRQis being encoded as HTML and you are converting them "to &quot;. This is how Razor works by default to avoid some security issues.

    In this case we want to embed the content in the JavaScript code instead of displaying it as HTML text, with @Html.Raw()the content being sent as is without encoding it.

    Also note that JSON is not the same as JavaScript. I recommend you change the JavaScriptSerializerfor another library that serializes JSON like Json.NET
