我有淘汰js应用程序，我需要将json数据与从服务器端获取的嵌套属性（不是json数组）绑定到视图模型，然后显示绑定到该视图模型的数据。到目前为止，我已经在这里尝试了一个小提琴，你能帮我将 json 数据映射到视图吗？
我的代码如下：
看法
<div>
<h2>WorkOrder Details</h2>
<ul data-role="listview" data-inset="true" data-theme="b" data-divider-theme="b">
<li data-role="list-divider">Work Order Details</li>
<li data-role="fieldcontain" data-bind="text:WorkOrderNo" id="WorkOrderNo"></li>
<li data-role="fieldcontain" data-bind="text:PurchaseOrderNo" id="PurchaseOrderNo"></li>
<li data-role="fieldcontain" data-bind="text:Status" id="Status"></li>
<li data-role="fieldcontain" data-bind="text:CallType" id="CallType"></li>
<li data-role="fieldcontain" data-bind="text:ServiceGroup" id="ServiceGroup"></li>
<li data-role="fieldcontain" data-bind="text:ServiceType" id="ServiceType"></li>
<li data-role="fieldcontain" data-bind="text:WorkDescription" id="WorkDescription"></li>
<li data-role="fieldcontain" data-bind="text:CreatedOn" id="CreatedOn"></li>
<li data-role="fieldcontain" data-bind="text:ExpectedCompletionOn" id="ExpectedCompletion"></li>
<li data-role="fieldcontain" data-bind="text:ExtendedTo" id="ExtendedTo"></li>
<li data-role="fieldcontain" data-bind="text:OnsiteOn" id="OnsiteOn"></li>
<li data-role="fieldcontain" data-bind="text:AssignedContractor" id="AssignedContractor"></li>
<li data-role="list-divider">Location</li>
<li data-role="fieldcontain">
<a data-bind="attr: { 'data-coordinates': getPropertyCoordinates }" class="property-coordinates" data-role="button" data-ajax="false" href="#"></a>
</li>
</ul>

};
//Return the property coordinates from bound data
self.getPropertyCoordinates = ko.computed(function() {

return self.PropertyAddress.Latitude + " , " + self.PropertyAddress.Longitude;
},self);
};
//function binding work order details to view
self.fetchWorkOrderDetails = function () {
$.map(data,WorkOrderDetails);
};
ko.applyBindings(WorkOrderDetails);
// Data that comes as JSON
var data = {
