MVC控制器中,经常使用Newtonsoft.Json把对象序列化成json字符串传递到前端视图。当对象中有DateTime类型的属性时,前后台如何处理才能把DateTime类型转换成想要的格式呢?
有这样的一个类具有DateTime类型属性:
using System;
namespace MvcApplication1.Models
{
public class Sample
{
public int Id { get; set; }
public string Name { get; set; }
public DateTime Date { get; set; }
}
}
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
控制器中使用Newtonsoft.Json把对象实例序列化成json字符串:
using System.Web.Mvc;
using MvcApplication1.Models;
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
namespace MvcApplication1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
var sample = new Sample()
{
Id = 1,
Name = "good",
Date = DateTime.Now
};
JsonSerializerSettings microsoftDateFormatSettings = new JsonSerializerSettings
{
DateFormatHandling = DateFormatHandling.MicrosoftDateFormat,
DateTimeZoneHandling = DateTimeZoneHandling.Utc
};
ViewData["json"] = Newtonsoft.Json.JsonConvert.SerializeObject(sample, microsoftDateFormatSettings);
return View();
}
}
}
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
前台视图使用一个叫"f"的js文件,把json中的日期格式转换成期望的样子:
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<p>
<span id="jsonDate">@ViewData["json"]</span>
</p>
<p>
转换后的时间格式为:<span id="fDate"></span>
</p>
@section scripts
{
<script src="~/Scripts/date.f-0.5.0.js"></script>
<script type="text/javascript">
$(function () {
var obj = $.parseJSON($('#jsonDate').text());
//$('#fDate').text(new Date(parseInt(obj.Date.substr(6))).f("yyyy-MM-dd HH:mm:ss"));
$('#fDate').text(new Date(parseInt(obj.Date.substr(6))).f("yyyy-MM-dd"));
});
</script>
}
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
结果:
