loading a knockout.js observableArray() from .ajax() call

There is no reason this would not work fine. As this demonstrates.

http://jsfiddle.net/madcapnmckay/EYueU/

I would check that the ajax post is actually returning json data and that that json is an array and that it's being parsed correctly.

I had to tweak the ajax call to get the fiddle ajax handlers to work correctly.

Nothing more I can think of.

Hope this helps.

var self=this;//var self first line in model$.ajax({            url: ",            dataType: "json",            contentType: 'application/json',            type: "POST",            data: JSON.stringify({ }),            processdata: true,            beforeSend: function () {                $.mobile.loading('show');            },            error: function (xhr, textStatus, errorThrown) {                alert('Sorry!');            },            success: function (data) {                $.mobile.loading('hide');                if (data.result!= '') {                    self.vendors(data.result);                } else {                    self.vendors({something});                }            }        });

Use self.vendors not this viewModel.vendors

Here is what I done in my MVC .net app with knockout and jquery.

// Scripts/groItems.js(function () {    var ViewModel = function () {        items = ko.observableArray(),            ItemName = ko.observable(),            Img = ko.observable(),            Qty = ko.observable()    }    $.getJSON('/Items2/AllItems', function (data) {        for (var i = 0; i < data.length; i++) {            self.items.push(data[i]);        }    });    var vm = new ViewModel();    $(function () {        ko.applyBindings(vm);    });}());

@model IEnumerable<GroModel.Item>@{    ViewBag.Title = "Index";}<p>    @Html.ActionLink("Create New", "Create")</p><div data-bind="text: items().length"></div><table class="container table table-hover">    <thead>        <tr>            <th>Item name</th>            <th>img</th>            <th>qty</th>        </tr>    </thead>    <tbody data-bind="foreach: items">        <tr>            <td data-bind="text: ItemName"></td>            <td data-bind="text: Img"></td>            <td data-bind="text: Qty"></td>        </tr>    </tbody></table>@section Scripts {    <script src="~/Scripts/knockout-3.4.2.js"></script>    <script src="~/Scripts/groItems.js"></script>}
