在输入类型时间中显示HH：MM

I am trying to use an html input field with the following code:

我正在尝试使用带有以下代码的html输入字段:

<td><input style="width: 80px" type="time" placeholder="HH:MM" required="" data-bind="value: FirstManifest"></td>

The backend C# object containing the FirstManifest property (DateTime?) is populated correctly but when I bind it to a knock view model, the property in the model FirstManifest looks like this

正确填充包含FirstManifest属性(DateTime?)的后端C#对象,但是当我将其绑定到knock视图模型时,模型FirstManifest中的属性看起来像这样

"/Date(1464748440000)/"

How can I convert this so my input only shows the datetime format HH:MM?

我怎么能转换这个,所以我的输入只显示日期时间格式HH:MM?

This is how .NET serializes it DateTime i believe. You first need to convert it to JavaScript Date and then get the time element, e.g.

这就是.NET如何序列化我相信的DateTime。首先需要将其转换为JavaScript Date,然后获取时间元素,例如

var manifest 
  = new Date(parseInt("/Date(1464748440000)/".replace("/Date(", "").replace(")/",""), 10));

this.FirstManifest = ko.computed(function() {
    return manifest.toLocaleTimeString();
}, this);

you will also need the write part of the computed to convert back from the input to date for persisting to the server.

您还需要计算的写入部分,以便从输入转换回日期以便持久保存到服务器。

It gets converted to milliseconds.Try converting it back like this.

它被转换为毫秒。尝试将其转换回来。

var oldDate= "/Date(1464748440000)/";
var newDate = new Date(parseInt(oldDate.substr(6)));
document.write(newDate);
