我正在使用 Knockout 并将 ViewModel 绑定到我的 ASP.Net MVC 4 项目中的数据对象,如下所示:
$(document).ready(function() {
properties = @Html.Raw(Json.Encode(Model));
selectedProperty = properties[0];
viewModel = { properties: ko.mapping.fromJS(@Html.Raw(Json.Encode(Model))), selectedProperty: ko.observable()};
viewModel.setItem = function(item) {
viewModel.selectedProperty(item);
}
ko.applyBindings(viewModel);
现在我想重构我的 JavaScript,以便将逻辑封装在一个类中:
RealEstate.Search = function (properties) {
this.properties = properties;
this.selectedProperty = this.properties[0];
this.viewModel = { properties: ko.mapping.fromJS(this.properties), selectedProperty: ko.observable()};
this.viewModel.setItem = function(item) {
viewModel.selectedProperty(item);
}
ko.applyBindings(this.viewModel);
}
我正在我的 HTML 页面中实例化该对象,如下所示:
$(document).ready(function() {
search = new RealEstate.Search(@Html.Raw(Json.Encode(Model)));
}
现在,我收到以下错误:
错误:无法解析绑定。消息:ReferenceError:“属性”未定义;绑定值:foreach:properties
这是绑定到 ViewModel 的表格的 HTML 片段:
<div id="divDataTable" data-bind="with: properties">
<table id="dataTable" class="tablesorter">
<thead>
<tr>
<th>Address
</th>
<th>
Suburb
</th>
<th>Price
</th>
<th>Beds
</th>
<th>Baths
</th>
<th>Days Listed
</th>
</tr>
</thead>
<tbody data-bind="foreach: properties">
<tr data-bind="click: $root.setItem">
<td>
<label data-bind="text: $data.Street"></label>
<input data-bind="attr: { value : $index(), id : $index(), name : $index() }" type="hidden" />
</td>
<td data-bind="text: $data.Suburb"></td>
<td data-bind="text: $data.PriceFormatted"></td>
<td data-bind="text: $data.NumOfBedrooms"></td>
<td data-bind="text: $data.NumOfBathrooms"></td>
<td data-bind="text: $data.DaysListed"></td>
</tr>
</tbody>
</table>
</div>
</section>
<div id="divProperty">
<aside class="float-right" data-bind="with: selectedProperty">
<table>
<tr>
<td>
<label data-bind="text: $data.Street"></label>
</td>
<td>
<label data-bind="text: $data.PriceFormatted"></label>
</td>
</tr>
<tr>
<td colspan="2">
<img src="#" /></td>
</tr>
<tr>
<td>Beds:
<label data-bind="text: $data.NumOfBedrooms"></label>
</td>
<td>On OZMite:
<label data-bind="text: $data.DaysListed"></label>
</td>
</tr>
<tr>
<td>Baths:
<label data-bind="text: $data.NumOfBathrooms"></label>
</td>
<td>Year built:</td>
</tr>
</table>
</aside>
如果有人能阐明我做错了什么,我将不胜感激。
