    <p>I got the following piece of code</p> <pre><code>function pushJsonData(productName) { $.ajax({ url: "/knockout/SaveProduct", type: "POST", contentType: "application/json", dataType: "json", data: " { \"Name\" : \"AA\" } ", async: false, success: function () { loadJsonData(); }, error: function (jqXHR, textStatus, errorThrown) { alert(textStatus + " in pushJsonData: " + errorThrown + " " + jqXHR); } }); } </code></pre> <p>Notice that I hard coded the data value. The data get pushed into the database fine. However, I keep getting the error "parsing error syntax error unexpected end of input". I am sure my data is in correct JSON syntax. When I checked with on Network of Chrome inspector the saveProduct request showed the data is correct. </p> <pre><code>{ "Name": "AA" } </code></pre> <p>This POST request did not have response. So I am clueless as to where the parse error was coming from. I tried using FireFox browser. the same thing happened.</p> <p>Can anyone give some idea as to what is wrong?</p> <p>Thanks, </p> <p>P.S. Here is the controller code</p> <pre><code>namespace MvcApplJSON.Controllers { public class KnockoutController : Controller { // // GET: /Knockout/ public ActionResult Index() { return View(); } [HttpGet] public JsonResult GetProductList() { var model = new List&lt;Product&gt;(); try { using (var db = new KOEntities()) { var product = from p in db.Products orderby p.Name select p; model = product.ToList(); } } catch (Exception ex) { throw ex; } return Json(model, JsonRequestBehavior.AllowGet); } [HttpPost] public void SaveProduct (Product product) { using (var db = new KOEntities()) { db.Products.Add(new Product { Name = product.Name, DateCreated = DateTime.Now }); db.SaveChanges(); } } } } </code></pre>

    1. CO`" { \"Name\" : \"AA\" } "` -> `" { 'Name' : 'AA' } "` there is a difference between `"` and `'` inside a json object

    2. COYes, and your second example produces invalid JSON. Single quotes are not valid JSON!

    3. CO@DarinDimitrov this works also from what I saw(you can try it on http://jsonviewer.stack.hu), but you can't send a string as an object(if you don't have that object with the string name avaible). So in the end: you're right

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
