Hi Currently I am facing issues in the "Max" attribute in lightning-input but max attribute is not working properly in some cases.

My requirement is to disable dates after One year of the Current date.

I got Full date in 11 months but I want the full date in 12 months so that I can give to the max attribute

Below is the attached Screenshot -

Here is the Playground link for your reference

Here is the code below



 <lightning-input label="From Date" type="date" name="fromDate"
                                    message-when-bad-input="Entered Date value is not a valid Date"
                                    onchange={fromdatevalueonchange} placeholder="dd MMM, yyyy" max={fulldate}
                                    message-when-range-overflow="Entered Date value is not a valid Date" required>

And JS Code :-

import { LightningElement } from 'lwc';

export default class LightningExampleInputDate extends LightningElement {
     var x = 12; //or whatever offset
        this.CurrentDate = new Date();
       console.log("Current date:", this.CurrentDate);
       this.CurrentDate.setMonth(this.CurrentDate.getMonth() + x);
       console.log("Date after " + x + " months:", this.CurrentDate);
       this.fulldate = this.CurrentDate.getFullYear() +'-'+this.CurrentDate.getMonth()+'-'+this.CurrentDate.getDate();

       console.log("full date --"+this.fulldate);
  • Do you want it to be a fiscal year or the calendar year? Dec 30 '19 at 16:23

The issue is here this.CurrentDate.getMonth().

The month starts with 0 and not 1.

0 -> Jan
1 -> Feb
10 -> Nov
11 -> Dec

Thus to fix your code, you have to add 1 in your month when you create full date.

this.fulldate = this.CurrentDate.getFullYear() +'-'+(this.CurrentDate.getMonth()+1)+'-'+this.CurrentDate.getDate();
