How Can I Format Dates in ASP.NET MVC's JsonResult to Avoid the '/Date(ticks)/' Format?

ASP.NET MVC JsonResult Date Formatting

In ASP.NET MVC, when returning a JsonResult containing a model with a date property, the default behavior is for the date to be serialized in the "/Date(ticks)/" format. However, this may not always be the desired format for consuming applications.

To handle the "/Date(ticks)/" format in JavaScript, there are several options:

Parse the String

One approach is to parse the serialized date string using string manipulation:

value = new Date(parseInt(value.replace("/Date(", "").replace(")/",""), 10));

Reviver Function in JSON.parse()

When using JSON.parse(), you can specify a reviver function to modify the parsed values before they are returned. For example, to convert "/Date(ticks)/" strings to JavaScript dates:

var parsed = JSON.parse(data, function(key, value) {
  if (typeof value === 'string') {
    var d = /\/Date\((\d*)\)\//.exec(value);
    return (d) ? new Date(+d[1]) : value;
  }
  return value;
});
