从字面上看,moment()。add()在我的js代码中不起作用。
var theDate = moment(event.start.format("YYYY-MM-DD HH:mm")); //start Date of event
var checkquarter = theDate.add(30, 'minutes');
var plus = 30;
if (userDuration == '45') {
plus = 45;
}
for (var i = 0; i < excludedList.length; i++) {
var excludedTomorrow = moment(excludedList[i]["excludedDate"]).format("YYYY-MM-DD HH:mm"); //start Date of event that should be excluded
var endtime = moment(excludedTomorrow).add(plus, 'minutes'); //endTime of event that should be excluded
if (excludedList[i]["id"] == 'aaa@gmail.com') {
console.log(endtime);
console.log(plus);
console.log(theDate);
console.log(checkquarter);
}
//var endtimeForCompare = moment(endtime);
if (theDate >= excludedTomorrow && theDate < endtime && Id == excludedList[i]["id"]) {
return false;
}
}

在这段代码中,我使用矩加法两次。首先是checkquarter,将其添加到Date变量中30分钟。第二个是结束时间,它是我从数据库中获得的,加上被排除在明天之外的分钟数。
这是控制台 console response 如果您看到此图像,它将按顺序显示结束时间,日期,checkquarter变量。但是,如您所见,没有添加任何内容。
我的momentJS脚本是

答案 0 :(得分:0)
您应该将theDate
克隆到checkQuarter
中,因为时刻是可变的。
https://momentjs.com/docs/#/manipulating/
这意味着var checkquarter = theDate.add(30, 'minutes');
正在更改theDate
,而checkQuarter
只是对theDate
的另一个引用。
运行以下命令时,请查看控制台:
var theDate = moment("1995-12-25 14:00");
console.log(theDate.toString());
var newDate = theDate.add(10, "minutes");
console.log(theDate.toString());
console.log(newDate.toString());
var anotherDate = moment(theDate);
anotherDate.add(10, "minutes");
console.log(anotherDate.toString());
console.log(theDate.toString());
