比较余烬中的两个日期

Question

如果有结束日期，我想验证结束日期应该是最大或等于生效日期的日期

effectiveDate: validator('presence', {
presence: true,
message: 'Please enter a valid value'
}), 

endDate: validator('presence', {
value(model, attribute) {
// Validate a value that is not the current attribute
var effectiveDate  = new Date(this.get('model').get('effectiveDate'));
var endDate  = new Date(this.get('model').get('endDate'));
 presence: effectiveDate > endDate;
},
message: 'Please enter a date value'
})

结束日期不是固定的

Answer 1

如果您使用 moment.js 进行日期格式化等，您可以将两个日期与“.diff”进行比较，例如

var now = moment();
// new date if "your date" is formatted
moment(new Date(this.get('your_date'))).diff(now,'days')
// result is difference in days from given date to now

Search for "Invalid Moments" in the docs

Answer 2

简单完成

endDate: validator('date', {

dependentKeys: ['effectiveDate'],
after : function () {
    return this.get('model').get('effectiveDate');
}
}),
