Dynamically show / hide a component if its date is not between 2 other dates
I have two inputs: <input type="date" id="fromDate">
and <input type="date" id="toDate">
, and then a *ngFor
loop iterating through a list of items. All of these items have a property activity_date
.
I want to be able to only show the components having their activity_date
property between the dates of fromDate
and toDate
. For this, I am using MomentJS, more precisely the function moment(activity_date).isBetween(fromDate, toDate)
.
The problem here is I want to assign the result of the previous method to a [hidden]
attribute so if an input
is changed, the [hidden]
property will be updated.
But here's the catch. How can I do to show / hide the components whenever the inputs
are changed ?
Here's what I've tried so far:
view.component.html
<app-events
type="calendar-item"
[hidden]="moment(item.activity_date).isBetween(this.fromDate, this.toDate);"
[data]="item"
></app-events>
view.component.ts
import { Component, OnInit } from "@angular/core";
import * as moment from "moment";
@Component({
selector: "app-view",
templateUrl: "./view.component.html",
styleUrls: ["./view.component.css"]
})
export class ViewComponent implements OnInit {
fromDate: string;
toDate: string;
item = [
{
id: 1,
activity_date: "14 November 2018",
}
];
ngOnInit() {}
isBetweenDate(date: string) {
return moment(date).isBetween(this.fromDate, this.toDate);
}
}
It works if I write values in the method by hand, and it only works at the loading of the page.
I was trying to look after the EventEmitter
or the Custom Attributes, but I'm not sure I am moving to the right direction.

I think you have done almost right. You made
isBetweenDate
function but don't use it.
I have created an example for you. It is same as your one, but not exact one. It compares the date with fromDate
and toDate
. So here, you can change dates and you will get an instant output based on the changed dates.
