背景:
您好,我正在开发网球俱乐部管理的在线应用...我想创建一个“可用的网球场界面”,允许用户检查球场是忙还是免费...所以在我的界面我有一个DatePicker,一个网球俱乐部的“谷歌地图”图像和代表所有网球场的13个标签。所以在这个界面中,如果网球场很忙,我想用红色“标记”标签,如果网球场是免费的,那就是绿色...
这是我的界面:
代码
为此,我正在使用Jquery,JavaScript和Json ......这是我在我的视图中尝试制作的内容:
<script type="text/javascript">
function loadCourts() {
var maDate = $('#datePicker').val();
$.post({
type: 'POST',
url: ({source:'@Url.Action("GetTennisCourt", "AvailableCourt")'}),
data: "{ 'date' : " + maDate + " }",
contentType: 'application/json; charset=utf-8',
dataType: 'json',
timeout: 8000,
success: function(data) {
alert('test');
//How to use data and verify if a tennis is free or not ?
},
error: function(x, t, m) {
if (t === "timeout") {
window.HandleTimeout();
} else {
alert(t);
}
}
});
}
</script>
<h2>Emplacement(s) disponible(s)</h2>
<input id="datePicker" type= "text"/>
<script type="text/javascript">
$(document).ready(function () {
$('#datePicker').datetimepicker();
$('#datePicker').change(chargerCourts());
});
</script>
//Here the label
<div class="AvailableCourt">
<div class="label1" align="center">
@Html.Label("1")
</div>
<div class="label2" align="center">
@Html.Label("2")
</div>
<div class="label2" align="center">
@Html.Label("3")
</div>
<div class="label2" align="center">
@Html.Label("4")
</div>
<div class="label3" align="center">
@Html.Label("5")
</div>
<div class="label4" align="center">
@Html.Label("6")
</div>
<div class="label5" align="center">
@Html.Label("7")
</div>
<div class="label6" align="center">
@Html.Label("8")
</div>
<div class="label7" align="center">
@Html.Label("9")
</div>
<div class="label8" align="center">
@Html.Label("10")
</div>
<div class="label9" align="center">
@Html.Label("11")
</div>
<div class="label10" align="center">
@Html.Label("12")
</div>
<div class="label11" align="center">
@Html.Label("13")
</div>
}
</div>
控制器方法
//Get all the tennis courts and verify if a court is busy or not (Available attribute)
public JsonResult GetTennisCourt(DateTime date)
{
System.Diagnostics.Debug.WriteLine("test");
var reservations = db.Reservations.Include(c => c.Customer);
foreach (var reservation in reservations)
{
//Verify that a court is available or not
if (reservation.Date ==date)
{
if (date.Hour > reservation.FinishTime.Hour || date.Hour < reservation.StartTime.Hour)
{
var id = reservation.TennisCourtID;
TennisCourt tennisCourt = (TennisCourt) db.TennisCourts.Where(t => t.ID == id);
tennisCourt.Available = true;
db.Entry(tennisCourt).State = EntityState.Modified;
db.SaveChanges();
}
else
{
var id = reservation.TennisCourtID;
TennisCourt tennisCourt = (TennisCourt) db.TennisCourts.Where(s => s.ID == id);
tennisCourt.Available = false;
db.Entry(tennisCourt).State = EntityState.Modified;
db.SaveChanges();
break;
}
}
}
var courts = from c in db.TennisCourts
select c;
courts = courts.OrderBy(c => c.ID);
System.Diagnostics.Debug.WriteLine("test");
return Json(courts, JsonRequestBehavior.AllowGet );
}
当我使用Firebug时,我的函数“loadCourts”出错,因此我的控制器方法(getTennisCourts)永远不会到达)我不明白为什么:
问题
所以,我的问题是:
1)为什么我在Firebug中出错?
2)为什么我的Controller的方法永远不会到达?
3)我如何在我的“loadCourts”功能中使用“数据”来检查网球场是否免费?
对不起,请提前感谢...
对于Darin Dimitrov:

我不知道C#,但这一行:
url: ({source:'@Url.Action("GetTennisCourt", "AvailableCourt")'}),
如果您有
,则将网址解析为对象url : '/path/to/controller'
它可能有效
成功函数中的'data'是JSON,因此您可以将其视为对象。
data.xyz
答案 1 :(得分:1)
试试这样:
// get the underlying Date object from the datepicker instead
// of using .val()
var maDate = $('#datePicker').datepicker('getDate');
$.ajax({
type: 'POST',
url: '@Url.Action("GetTennisCourt", "AvailableCourt")',
data: '{ "date":"\\/Date(' + maDate.getTime() + ')\\/" }',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
timeout: 8000,
success: function(data) {
// we loop through the collection of courts
// returned by the server and we can access each
// element's properties
$.each(data, function(index, court) {
alert(court.ID);
});
},
error: function(x, t, m) {
if (t === 'timeout') {
window.HandleTimeout();
} else {
alert(t);
}
}
});
请注意,我使用的是$.ajax
而不是$.post
。我使用了datepicker的getDate
方法来获取本机Date对象并对其进行编码。
