从变量获取事件
getting the event from variable
我正在研究来自 github 的 jquery 日历:https://github.com/themouette/jquery-week-calendar
我使用 C# 代码从数据库中提取数据,并将其存储在 hiddenfield,然后 javascript 读取 hiddenfield 字段值作为字符串。
我将跳过如何从数据库中获取值,在这个问题中,我将事件硬编码到 sampleEvents var 中。
工作 Javascript:
var eventData = {
events: [
{'id':1, 'start': new Date(2015, 3, 27, 12), 'end': new Date(2015, 3, 27, 13, 35),'title':'Lunch with Mike'},
{'id':2, 'start': new Date(2015, 3, 28, 10), 'end': new Date(2015, 3, 28, 14, 45),'title':'Dev Meeting'}
]};
不工作Javascript:
var sampleEvents = "{'id':1, 'start': new Date(2015, 3, 27, 12), 'end': new Date(2015, 3, 27, 13, 35),'title':'Lunch with Mike'},{'id':2, 'start': new Date(2015, 3, 28, 10), 'end': new Date(2015, 3, 28, 14, 45),'title':'Dev Meeting'}";
var eventData = {
events: [
sampleEvents
]};
错误信息:
Uncaught TypeError: Cannot read property 'getTime' of undefined
不工作Javascript 2:
var sampleEvents = "[{'id': 1,'start': new Date(2015, 3, 27, 12),'end': new Date(2015, 3, 27, 13, 35),'title': 'Lunch with Mike'},{'id': 2,'start': new Date(2015, 3, 28, 10),'end': new Date(2015, 3, 28, 14, 45),'title': 'Dev Meeting'}]";
var array = JSON.parse(sampleEvents);
var eventData = {
events:
sampleEvents
};
错误信息:
Uncaught SyntaxError: Unexpected token '
谁能告诉我,我错过了什么?
因为你创建的 sampleEvents
是字符串而不是数组。
event
正在接受 array
而不是 string
。
要使用数组试试这个:
var sampleEvents = [
{
'id':1,
'start': new Date(2015, 3, 27, 12),
'end': new Date(2015, 3, 27, 13, 35),
'title':'Lunch with Mike'
},
{
'id':2,
'start': new Date(2015, 3, 28, 10),
'end': new Date(2015, 3, 28, 14, 45),
'title':'Dev Meeting'
}
];
要使用字符串试试这个:
var sampleEvents = '['+
'{"id":1, "start": "'+new Date(2015, 3, 27, 12)+'", "end": "'+new Date(2015, 3, 27, 13, 35)+'","title":"Lunch with Mike"},'+
'{"id":2, "start": "'+new Date(2015, 3, 28, 10)+'", "end": "'+new Date(2015, 3, 28, 14, 45)+'","title":"Dev Meeting"}'+
']';
var sampleEventsArray = JSON.parse(sampleEvents);
