我正在使用FullCalendar(http://arshaw.com/fullcalendar/),我需要帮助将使用json的数据传递到我的ASP.net页面的代码隐藏页面中的c#函数。
我正在使用json在我的FullCalendar Web应用程序中加载数据:
代码背后:
[WebMethod]
public static List<Event> GetEvents()
{
List<Event> events = new List<Event>();
events.Add(new Event()
{
EventID = 1,
EventName = "EventName 1",
StartDate = DateTime.Now.ToString("MM-dd-yyyy"),
EndDate = DateTime.Now.AddDays(2).ToString("MM-dd-yyyy"),
EventColor = "red"
});
events.Add(new Event()
{
EventID = 2,
EventName = "EventName 2",
StartDate = DateTime.Now.AddDays(4).ToString("MM-dd-yyyy"),
EndDate = DateTime.Now.AddDays(5).ToString("MM-dd-yyyy"),
EventColor = "green"
});
return events;
}
asp.x页面:
events: function(start, end, callback)
{
$.ajax(
{
type: 'POST',
contentType: 'application/json',
data: "{}",
dataType: 'json',
url: "Calendar.aspx/GetEvents",
cache: false,
success: function (response) {
var events = $.map(response.d, function (item, i) {
var event = new Object();
event.id = item.EventID;
event.start = new Date(item.StartDate);
event.end = new Date(item.EndDate);
event.title = item.EventName;
event.color = item.EventColor;
return event;
})
callback(events);
},
error: function (err) {
alert('Error');
}
});
},
这很好用。现在我想通过调用函数并传递数据来保存数据。以下是我到目前为止所做的事情:
代码背后:
[WebMethod]
public static bool SaveEvents(List<Event> events)
{
//iterate through the events and save to database
return true;
}
asp.x页面
function save() {
var eventsFromCalendar = $('#calendar').fullCalendar('clientEvents');
var events = $.map(eventsFromCalendar, function (item, i) {
var event = new Object();
event.id = item.id;
event.start = item.start;
event.end = item.end;
event.title = item.title;
event.color = item.color;
return event;
});
$.ajax(
{
type: 'POST',
contentType: 'application/json',
data: JSON.stringify(events), **<-- I have to pass data here but how???**
dataType: 'json',
url: "Calendar.aspx/SaveEvents",
cache: false,
success: function (response) {
alert('Events saved successfully');
},
error: function (err) {
alert('Error Saving Events');
}
});
return false;
}
上面的ajax帖子是我需要帮助的地方。变量事件包含所有FullCalendar事件信息。 如何传递数据&#39;事件&#39;功能&#39; SaveEvents&#39;? 如果需要,我可以更改SaveEvents签名。
EDIT 如果我改变我的c#函数来使用像s0这样的数组:
[WebMethod]
public static bool SaveEvents(Event[] newEvents)
{
return true;
}
并通过以下数据传递:
data: JSON.stringify({ newEvents: events }),
然后使用大小为4的数组调用&#39; SaveEvents&#39; 函数,但所有数据值都为null,为什么会这样?
由于
答案 0 :(得分:1)
从您的代码中可以看出,您将c#类作为
public class Events
{
public int EventID {get; set;}
public string EventName {get;set;}
public StartDate {get; set;}
public string end {get; set;}
public string color {get; set;}
}
所以拿json数组。这是一个样本 //将作为数据提供给c#方法的数组
var newEvents=[
{
EventID : 1,
EventName : "EventName 1",
StartDate : "2015-01-01",
EndDate : "2015-01-03",
EventColor : "red"
},
{
EventID : 2,
EventName : "EventName 2",
StartDate : "2015-01-02",
EndDate : "2015-01-04",
EventColor : "green"
}
];
现在是将JSON对象传递给发布的URL的ajax请求
$.ajax
({
type: 'POST',
contentType: 'json',
data: {newEvents:newEvents},// Pass data as it is. Do not stringyfy
dataType: 'json',
url: "Calendar.aspx/SaveEvents"
success: function (response) {
alert('Events saved successfully');
},
error: function (err) {
alert('Error Saving Events');
}
});
更新:
要确保没有其他错误,请将您的保存活动测试为。如果它正常,上面应该也可以,因为它适合我:)
[WebMethod]
public static bool SaveEvents(string EventName)
{
//iterate through the events and save to database
return true;
}
$.ajax
({
type: 'POST',
contentType: 'json',
data: {EventName:'myevet 1'},
url: "Calendar.aspx/SaveEvents",
cache: false,
success: function (response) {
alert('Events saved successfully');
},
error: function (err) {
alert('Error Saving Events');
}
});
