目前，我的 page.html 如下，它大部分都在工作，但我有一些奇怪的地方，我的日期显示如下：
2013-05-24T13:09:40.927 2013-05-24T13:09:40.927 10>
•2013-05-24T13:11:32.823 2013-05-24T13:11:32.823 100>
•2013-05-24T13:12:22.653 2013-05-24T13:12:22.653 10>
•2012-12-12T00:00:00 2012-12-12T00:00:00 10>
日期解析它们会很好，但不知道该怎么做，我也想要2个输入字段：
<input type="date" class="ui-corner-all" data-bind="value: newPeriodFrom" />
<input type="date" class="ui-corner-all" data-bind="value: newPeriodTo" />
成为日期选择器甚至更好的屏蔽日期字段，这怎么可能？
