I need the jeditable plugin to update the ProductName in the database when it gets edited. As of right now the ProductName only updates on the page. I didn't install this plugin so I'm not familiar with how it works or the code behind it all. I am just looking for some help, I understand that the code might look funky, but I didn't write any of this. Thanks

ProductPage.js

$(document).ready(function () {
// EDIT PRODUCT NAME

$('.productName.edit').editable(function (value, settings) {
    var ProductID = $('input#body_ProductID').val();
    var result = SubmitProductName(ProductID, value);
    return (value);
}, {
    width: '350',
    submit: 'Save Changes',
    cancel: 'Cancel',
    onBlur: 'ignore'
});


// this makes the call to the webservice to update the product name

The problem is right here in the SubmitProductName function. After putting alerts in the javascript, I found out that the UpdateProductName url was never getting hit

function SubmitProductName(ProductID, NewName) {
    var result;
    **$.ajax({
        type: "POST",
        data: '{ "ProductID" : "' + ProductID + '", "UpdateText" : "' + NewName + '"}',
        url: '../WebService.asmx/UpdateProductName',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (json) {
            result = json.d;
        },**
        error: function (e) {
            result = "error";
        }
    });

}  
});

WebService.vb

'Updates a product and returns the new product name
<WebMethod()> _
Public Function UpdateProductName(ProductID As String, UpdateText As String) As String
    Dim sqlUpdate As String = "UPDATE Product SET ProductName = '" & UpdateText & "' WHERE ProductID = " & ProductID
    Dim sqlResults As String = "SELECT ProductName FROM Product WHERE ProductID = " & ProductID

    'Create sql connection object
    Dim sqlConn As New SqlConnection("Server=off-db1;uid=productsDB_admin;pwd=*******;database=Products")

    'Open SQL connection
    sqlConn.Open()

    'SQL Statement to get CategoryIDs and Names of all subcategories
    Dim myCommand As New SqlCommand(sqlUpdate, sqlConn)

    myCommand.ExecuteNonQuery()

    Dim cmdResults As New SqlCommand(sqlResults, sqlConn)
    Dim myReader As SqlDataReader = cmdResults.ExecuteReader()
    Dim results As String = Nothing

    While myReader.Read
        results = myReader(0)
    End While

    myReader.Close()
    sqlConn.Close()

    Return results

End Function

You need to write the backend to do the DB update. Javascript is run on the client and can't possibly do it itself. In ASP.NET, you'd usually write a Web Service (.svc or .asmx) that receives the POST jEditable can send to do the database update.

When you call .editable() on an element, the first argument is the URL it should post the result to -- that should point to your web service.

From jEditable's web page:

$(document).ready(function() { $('.edit').editable('http://www.example.com/save.php'); });

In that case, save.php is the PHP web service... substitute your own.


Try running some diagnostics on your ajax request using something like Firebug. This should give you an idea of what type of issues the request is running into.

My first guess would be url:

'../WebService.asmx/UpdateProductName'

is either one looking in the wrong directory, or two is getting denied by some authentication you have setup in your application.

You could do something like this to display error information about your ajax request on your screen
