Angular 2 Ionic 2 - 如何将日期输入的最大或最小日期设置为今天？

Question

 <input class="alert-input date-input" #dob="ngModel" name="dob" max="2018-03-07" [(ngModel)]="leadDetail.dob" type="date"></div>

How can I set the max date for today instead of 2018-03-07 dynamically?

I tried following methods-

 <input  max="today" type="date"></div>
 <input  max="{{today | date:'yyyy-mm-dd'}}" type="date"></div>

Class -

public today = new Date();

but no luck.

Answer 1

Try this:

<input class="alert-input date-input" name="dob" [max]="today" type="date">


today = new Date().toJSON().split('T')[0];

Working Example Demo

Reason:

Becasue when you are using new Date() this will give you full date with time zone and time etc, you have to assign only Date so you have to split this with only Date. for more clerification run this

console.log(new Date(), '----', new Date().toJSON());

Answer 2

将mm更改为MM然后格式但这将影响您更改的日期，这将无助于除非其ngModel绑定到另一个变量

Answer 3

register.component.html

<div class="container">
<form #loginForm="ngForm" (ngSubmit)="submitLoginForm(loginForm)" style="background-  color:beige;">
<input [(ngModel)]="vdate"  name="dob"  type="date">

<button type="submit" [disabled]="!loginForm.valid || (today < vdate)" class="btn">Login</button>

</form>

</div>

register.component.ts

import { Component, OnInit } from '@angular/core';

@Component({
selector: 'app-register',
templateUrl: './register.component.html',
styleUrls: ['./register.component.css']
})
export class RegisterComponent implements OnInit {
vdate: Date
today = new Date().toJSON().split('T')[0];
constructor() {

}

ngOnInit() {

}
submitLoginForm() {
console.log("Welcome to Jollywood")
}
}
