I am trying to prevent users from selecting dates within the range specified by l1 and l2. However, my current method only disables the date 13.
var l1 = new Date("2019-07-13");
var l2 = new Date("2019-07-30");
this.flag = 0;
this.filter2 = function(date) {
var c = date.getDate();
for(i=l1.getDate();i<=l2.getDate();i++)
{
return c != i;
continue;
}
}
Timestamps are effective, but it's also important to take my comments into consideration
var start = new Date("2019-07-13");
var end = new Date("2019-07-30");
// The date format for end will include the time as well, so if you want it to be strictly for 2019-08-01, use this date directly or set end to new Date("2019-07-30 23:59:59.999")
// This method will return true if the date value provided to the function is outside the specified range
// For example, dates like: 2019-07-12, keep in mind that it will work for today's date due to the getTime method considering hours, minutes, seconds, and milliseconds
this.filter2 = function(date) {
return start.getTime() < end.getTime() && (date.getTime() < start.getTime() || date.getTime() > end.getTime())
}
console.log(filter2(new Date())) // In the case of today, based on the information mentioned above, it will return true
console.log(filter2(new Date('2019-07-15'))) // false
console.log(filter2(new Date('2019-07-12'))) // trueTo determine if a specific date falls within a certain range, you can compare the timestamps of the date with two reference dates, l1 and l2.
var l1 = new Date("2019-07-30");
var l2 = new Date("2019-07-13");
function checkDate(date) {
if (date instanceof Date && l1 instanceof Date && l2 instanceof Date) {
return l1.getTime() < l2.getTime() ? !(date.getTime() >= l1.getTime() && date.getTime() <= l2.getTime()) : !(date.getTime() >= l2.getTime() && date.getTime() <= l1.getTime())
} else {
return false;
}
}
console.log(checkDate(new Date("2019-07-13")));
console.log(checkDate(new Date("2019-07-12")));component.ts import { Component } from '@angular/core'; @Component({ selector: 'my-app', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { projectRating ...
