Hello,

I am new to jQuery and am working on an application that uses .NET4 (C#) + MVC3 + Razor view engine + jQuery + JSON.

Using Firefox v11 with the Firebug javascript debugger add-in.

In my viewpage .cshtml I have the following:

@using System.Linq;

@using System.Web.Script.Serialization;

@using Models;

@using Infrastructure;

@model Models.JobSettingsModel

@{

JobSettingsModel defModel = ViewBag.DefaultModel;

JavaScriptSerializer serializer = new JavaScriptSerializer();

string json = serializer.Serialize(defModel);

}

<script type="text/javascript">

var obj = '@Html.Raw(json)';

var oModel1 = jQuery.parseJSON(obj);

function foo() {

if (oModel1 != null) {

alert("OModel1 is not null");

}

else {

alert("oModel1 is null!");

}

if (obj != null) {

alert("obj is not null");

}

else {

alert("obj is null");

}

}

foo();

</script>

When I view my page in Firefox, Firebug's Script tab shows the javascript as:

<script type="text/javascript">

var obj =

'{"IncludeWatermark":false,"WatermarkText":"empty","IncludePageNumbering":false,"OverwriteOutputFileIfExists":

true,"OutputFilename":"dummyDefault.pdf","OutputLibraryLocation":"c:\\\\temporary","User":{"Name":"Sheir","DisplayName":"Sheir","GivenName":"Sheir","MiddleName":null,"Surname":"","SamAccountName":"sheir","IsActive":true,

"UserId":"mydomainINC\\\\sheir"},

"SharePointLocationUrl":null,"FeedbackUrl":null,"AppDescriptionUrl":null}';

var oModel1 = jQuery.parseJSON(obj);

Firebug's Console tab + Error tab shows:

uncaught exception: Invalid JSON:

{"IncludeWatermark":false,"WatermarkText":"empty","IncludePageNumbering":false,"OverwriteOutputFileIfExists":t

rue,"OutputFilename":"dummyDefault.pdf","OutputLibraryLocation":"c:\\temporary","User":{"Name":"Sheir",

"DisplayName":"Sheir","GivenName":"Sheir","MiddleName":null,"Surname":"","SamAccountName":"sheir","IsActive":true,"UserId

":"mydomainINC\\sheira"},"SharePointLocationUrl":null,"FeedbackUrl":null,"AppDescriptionUrl":null}

Line 0

**************************

First I copied the oModel1 parseJSON param (everything from the { to the } ) and stuck it in the

http://jsonlint.com/

and clicked their Validate button which says

{

"IncludeWatermark": false,

"WatermarkText": "empty",

"IncludePageNumbering": false,

"OverwriteOutputFileIfExists": true,

"OutputFilename": "dummyDefault.pdf",

"OutputLibraryLocation": "c:\\\\temporary",

"User": {

"Name": "Sheir",

"DisplayName": "Sheir",

"GivenName": "Sheir",

"MiddleName": null,

"Surname": "",

"SamAccountName": "sheir",

"IsActive": true,

"UserId": "mydomainINC\\\\sheira"

},

"SharePointLocationUrl": null,

"FeedbackUrl": null,

"AppDescriptionUrl": null

}

> Valid JSON

Then I copied the uncaught exception message and did same and got ...

{

"IncludeWatermark": false,

"WatermarkText": "empty",

"IncludePageNumbering": false,

"OverwriteOutputFileIfExists": true,

"OutputFilename": "dummyDefault.pdf",

"OutputLibraryLocation": "c:\\temporary",

"User": {

"Name": "Sheir",

"DisplayName": "Sheir",

"GivenName": "Sheir",

"MiddleName": null,

"Surname": "",

"SamAccountName": "sheir",

"IsActive": true,

"UserId": "mydomainINC\\sheira"

},

"SharePointLocationUrl": null,

"FeedbackUrl": null,

"AppDescriptionUrl": null

}

Parse error on line 16:

..., "UserId": "mydomainINC\\sheira"

----------------------^

Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['

So I am perplex to say the least.
