<div data-bind="foreach:
matters">
<div data-bind="if:
dateTime.length > 0">
<table>
<tr>
<td>
<label data-bind="text: dateTime"></label>
</td>
</tr>
</table>
</div>
</div>
<div class="time_data">
<table>
<tr>
<td>
<img src="~/Images/icon_status.png" /></td>
<td data-bind="foreach:
subMatter">
<div data-bind="text:
$data"></div>
</td>
<td>
<div data-bind="text:
hour"></div>
<a href="#">
<img src="~/Images/icon_options.png" />
</a>
</td>
</tr>
</table>
</div>
This is for viewModel code which use to display each row using foreach on matters collection [matters is a observable array]
<script
type="text/javascript">
$(document).ready(function () {
$.ajax({
url: "/MyTimeHome/GetMethod/",
type: 'post',
data: "{'matterId':'1' }",
contentType: 'application/json',
success: function (result) {
//
call to view model
getViewModel(result);
},
error: function (jqXHR, textStatus,
errorThrown) {
var errorMessage = '';
$('#message').html(jqXHR.responseText);
}
});
function getViewModel(result) {
//
Define a "matter" class.
var matter = function (dateTime, hour, subMatter) {
this.dateTime = dateTime;
this.hour = hour;
this.subMatter = ko.observableArray(subMatter);
}
var viewModel = {
matters: [],
showRenderTimes: ko.observable(false)
};
// push
all data in view model
for (var i = 0; i < result.length; i++) {
var matterRow = new matter(result[i].createdOn + " | " +
result[i].totalHours, result[i].totalHours,
[result[i].matterTitle,
result[i].MyProperty1, result[i].matterComment]);
viewModel.matters.push(matterRow);
}
// bind
view model to knockout
ko.applyBindings(viewModel);
}
});
