我有这个JS数组......
var arr = [{

}]
arr.sort((x,y) => y.all_day_evt- x.all_day_evt || ((new Date('1970/01/01 ' + x.Start_time)) - (new Date('1970/01/01 ' + y.Start_time))));
console.log(arr);
我希望在这个阵列上做3次操作......
我不确定如何实施第3个条件，非常感谢任何帮助。感谢
下面显示的示例输出 - 突出显示冲突事件应该如何排列。它应该显示出来，以便“碰撞”键的事件排在第2位，而不是第1位。
例如，事件“BW-013”＆amp; “BW-018”在下午12:30的开始时间发生冲突。因此，'BW-013'首先出现，然后'BW-018'出现。事件'BW-039'和'BW-162'也是如此，如下面的示例输出所示。
[{
"Event_code": "BW-013",
"Interest_area": "Sciences, Engineering, Information technology, Architecture and built environment, Environment",
"Start_time": "12:30 PM",
"End_time": "1:00 PM",
"Session_type": "Course information session",
"all_day_evt": false
},
{
"Event_code": "BW-018",
"Interest_area": "Sciences",
"Start_time": "12:30 PM",
"End_time": "2:30 PM",
"Session_type": "Tour",
"all_day_evt": false,
"clash": "This clashes with another session"
},
{
"Event_code": "BW-039",
"Interest_area": "Media, Communication and creative arts",
"Start_time": "1:00 PM",
"End_time": "1:30 PM",

答案 0 :(得分：1)
试试以下内容。您需要添加clash
var arr = [{"Event_code":"BW-087","Interest_area":"Information technology","Start_time":"9:00 AM","End_time":"3:00 PM","Session_type":"Experience","all_day_evt":true},{"Event_code":"BW-161","Interest_area":"Media, Communication and creative arts","Start_time":"9:00 AM","End_time":"3:00 PM","Session_type":"Experience","all_day_evt":true},{"Event_code":"BW-114","Interest_area":"Nursing and midwifery","Start_time":"9:00 AM","End_time":"3:00 PM","Session_type":"Tour","all_day_evt":true},{"Event_code":"BW-033","Interest_area":"","Start_time":"9:00 AM","End_time":"3:00 PM","Session_type":"General information session","all_day_evt":true},{"Event_code":"BW-115","Interest_area":"Food, Nutrition and dietetics","Start_time":"9:30 AM","End_time":"3:00 PM","Session_type":"Tour","all_day_evt":true},{"Event_code":"BW-060","Interest_area":"Sport","Start_time":"9:30 AM","End_time":"3:00 PM","Session_type":"Tour","all_day_evt":true},{"Event_code":"BW-081","Interest_area":"Information technology","Start_time":"9:00 AM","End_time":"9:30 AM","Session_type":"Course information session","all_day_evt":false},{"Event_code":"BW-170","Interest_area":"","Start_time":"9:30 AM","End_time":"10:30 AM","Session_type":"General information session","all_day_evt":false,"clash":"This clashes with another session"},{"Event_code":"BW-032","Interest_area":"","Start_time":"9:30 AM","End_time":"10:00 AM","Session_type":"General information session","all_day_evt":false},{"Event_code":"BW-096","Interest_area":"Media, Communication and creative arts","Start_time":"10:00 AM","End_time":"12:00 PM","Session_type":"Experience","all_day_evt":false},{"Event_code":"BW-163","Interest_area":"Business","Start_time":"10:00 AM","End_time":"2:00 PM","Session_type":"Experience","all_day_evt":false,"clash":"This clashes with another session"},{"Event_code":"BW-048","Interest_area":"Media, Communication and creative arts","Start_time":"12:00 PM","End_time":"12:30 PM","Session_type":"Experience","all_day_evt":false},{"Event_code":"BW-128","Interest_area":"Media, Communication and creative arts","Start_time":"12:00 PM","End_time":"12:30 PM","Session_type":"Tour","all_day_evt":false,"clash":"This clashes with another session"},{"Event_code":"BW-018","Interest_area":"Sciences","Start_time":"12:30 PM","End_time":"2:30 PM","Session_type":"Tour","all_day_evt":false,"clash":"This clashes with another session"},{"Event_code":"BW-013","Interest_area":"Sciences, Engineering, Information technology, Architecture and built environment, Environment","Start_time":"12:30 PM","End_time":"1:00 PM","Session_type":"Course information session","all_day_evt":false},{"Event_code":"BW-039","Interest_area":"Media, Communication and creative arts","Start_time":"1:00 PM","End_time":"1:30 PM","Session_type":"Experience","all_day_evt":false},{"Event_code":"BW-162","Interest_area":"Education and teaching","Start_time":"1:00 PM","End_time":"1:30 PM","Session_type":"Tour","all_day_evt":false,"clash":"This clashes with another session"}];
arr.sort((x,y) => y.all_day_evt- x.all_day_evt || ((new Date('1970/01/01 ' + x.Start_time)) - (new Date('1970/01/01 ' + y.Start_time))) || Boolean(x.clash) - Boolean(y.clash));
console.log(arr);
