使用 Asp.Net MVC 和 KnockoutJS 处理日期

我最近开始使用KnockoutJs，并很快意识到使用默认的Json(myModelWithADate)会产生默认的json编码\/Date(-62135578800000)\/.通过一些研究，我找到了四种可能的方法来处理dom元素中日期的显示.

1) Create a binding that handles the conversion from the Json date to the format you desire

ko.bindingHandlers.date = {
    init: function (element, valueAccessor, allBindingsAccessor, viewModel) {
        var jsonDate = valueAccessor();
        var value = new Date(parseInt(jsonDate.substr(6)));
        var ret = value.getMonth() + 1 + "/" + value.getDate() + "/" + value.getFullYear();
        element.innerHTML = ret;
    },
    update: function(element, valueAccessor, allBindingsAccessor, viewModel) {

    }
};

用法

<td data-bind="date: DueDate">
</td>

2) Return “strings” from your Controller

return Json(new {MyDate = DateTime.Now.ToShortDateString()});

3) Use the JSON.NET to specify a Date Time format seen over at 100

示例

string isoJson = JsonConvert.SerializeObject(entry, new IsoDateTimeConverter());
// {"Details":"Application started.","LogDate":"2009-02-15T00:00:00Z"}

4) use JSON.parse to handle your dates as seen in this 100

JSON.parse(jsonText, function(key, value) {
    // Check for the /Date(x)/ pattern
    var match = /\/Date\((\d+)\)\//.exec(value);
    if (match) {
        var date = new Date(+match[1]); // Convert the ticks to a Date object
        return humanReadable(date); // Format the date how you want it
    }

    // Not a date, so return the original value
    return value;
});

它们似乎都很管用，但我仍在为哪一种感觉"正确"而苦苦挣扎.现在，我的直觉是混合使用绑定和返回字符串.正如我可以看到的那样，我自己扩展了绑定以使用jQuery UI Datepicker控件处理输入.

Is there an accepted practice when handling displaying dates or other types such as currency? Is there another option I am missing that solves this problem?
