Restrict the number of decimal places at a float and validate a datetime at a Razor form!

@model Airport.Core.Objects.Flight
<h1>Add a Flight</h1>
@using (Html.BeginForm("Add", "Flight", FormMethod.Post, new {id="form"}))
{
   <div>
      @Html.LabelFor(m => m.Duration)
      @Html.TextBoxFor(m => m.Duration)
      @Html.ValidationMessageFor(m => m.Duration)
   </div>
   <div>
      @Html.LabelFor(m => m.DepartureTime)
      @Html.TextBox("Date", null, new { @type = "date" })
      @Html.TextBox("Time", null, new { @type = "time" })
      @Html.TextBoxFor(m => m.DepartureTime, new { @class="displaynone" })
      @Html.ValidationMessageFor(m => m.DepartureTime)
   </div>
   <div>
      <input type="submit" value="submit" onclick="var fate = prepare(); return fate;" />
   </div>
}

      var floaties = $("#Duration").val().split(".");

         $("span[data-valmsg-for='Duration']").html("Keep float small.");
         return false;
      } else {
         if (floaties[0].length > 2) {

               if (datetime.length < 16) {

                  return false;

The displaynone class just does what you'd expect.

.displaynone {
   display: none;
}
