这是一个非常简单的例子,我有一个带有数组的基本 JavaScript 对象,我正在使用敲除映射来使数组可观察等。
但是当我应用我的绑定时,我只会得到未定义。
任何想法为什么?
HTML
<div data-bind="with: Data">
<div class="tab-pane active" id="studydirections">
<div data-bind="template: { name: studydirectionstemplate, foreach: studydirections }">
</div>
</div>
</div>
<script id="studydirectionstemplate" type="text/html">
<div> <span data-bind="text: Name"> </span> </div>
</script>
JavaScript
var viewModel = {};
var data = {
studydirections: [{
RecId: 299,
ColtechCode: 75,
Name: "FARM",
Description: "FARMING"},
{
RecId: 306,
ColtechCode: 12,
Name: "BACC",
Description: "ACCOUNTING"},
{
RecId: 334,
ColtechCode: 11,
Name: "BMAN",
Description: "BUSINESS MANAGEMENT"
}
]};
viewModel.Data = ko.mapping.fromJS(data);
ko.applyBindings(viewModel);
结果是
undefinedundefinedundefined
