Validate date in dd/mm/yyyy format using JQuery Validate

javascript jquery validation date datetime

Solution 1

You don't need the date validator. It doesn't support dd/mm/yyyy format, and that's why you are getting "Please enter a valid date" message for input like 13/01/2014. You already have the dateITA validator, which uses dd/mm/yyyy format as you need.

Just like the date validator, your code for dateGreaterThan and dateLessThan calls new Date for input string and has the same issue parsing dates. You can use a function like this to parse the date:

function parseDMY(value) {
    var date = value.split("/");
    var d = parseInt(date[0], 10),
        m = parseInt(date[1], 10),
        y = parseInt(date[2], 10);
    return new Date(y, m - 1, d);
}

This will also checks in leap year. This is pure regex, so it's faster than any lib (also faster than moment.js). But if you gonna use a lot of dates in ur code, I do recommend to use moment.js

var dateRegex = /^(?=\d)(?:(?:31(?!.(?:0?[2469]|11))|(?:30|29)(?!.0?2)|29(?=.0?2.(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(?:\x20|$))|(?:2[0-8]|1\d|0?[1-9]))([-.\/])(?:1[012]|0?[1-9])\1(?:1[6-9]|[2-9]\d)?\d\d(?:(?=\x20\d)\x20|$))?(((0?[1-9]|1[012])(:[0-5]\d){0,2}(\x20[AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2})?$/;

console.log(dateRegex.test('21/01/1986'));

If you use the moment js library it can easily be done like this -

jQuery.validator.addMethod("validDate", function(value, element) {
        return this.optional(element) || moment(value,"DD/MM/YYYY").isValid();
    }, "Please enter a valid date in the format DD/MM/YYYY");

Solution 4

I encountered a similar problem in my project. After struggling a lot, I found this solution:

if ($.datepicker.parseDate("dd/mm/yy","17/06/2015") > $.datepicker.parseDate("dd/mm/yy","20/06/2015"))
    // do something

You DO NOT NEED plugins like jQuery Validate or Moment.js for this issue. Hope this solution helps.

This validates dd/mm/yyy dates. Edit your jquery.validate.js and add these.

Reference(Regex): Regex to validate date format dd/mm/yyyy

dateBR: function( value, element ) {
    return this.optional(element) || /^(?:(?:31(\/|-|\.)(?:0?[13578]|1[02]))\1|(?:(?:29|30)(\/|-|\.)(?:0?[1,3-9]|1[0-2])\2))(?:(?:1[6-9]|[2-9]\d)?\d{2})$|^(?:29(\/|-|\.)0?2\3(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))$|^(?:0?[1-9]|1\d|2[0-8])(\/|-|\.)(?:(?:0?[1-9])|(?:1[0-2]))\4(?:(?:1[6-9]|[2-9]\d)?\d{2})$/.test(value);
}

messages: {
    dateBR: "Invalid date."
}

classRuleSettings: {
    dateBR: {dateBR: true}
}

Usage:

$( "#myForm" ).validate({
    rules: {
        field: {
            dateBR: true
        }
    }
});

I am taking input of date of birth and date of death. Validation required

date of death should be more than date of birth
Date format to be dd/mm/yyyy
Dates to be less than or equal to today.

Validate doesn't work as expected and can't figure out the problem. Please help.

JS libraries used

JQuery UI for Calendar/Datepicker
JQuery validate for form validation

Additional methods for validation library

var today = new Date();
var authorValidator = $("#itemAuthorForm").validate({

        dateITA : true,
        dateGreaterThan : "#dateOfBirth"
    }

onfocusout : function(element) {

changeMonth : true,
changeYear : true,
onClose : function(selectedDate) {
    $("#expiredDate").datepicker("option", "minDate", selectedDate);

jQuery.validator.addMethod("dateGreaterThan",
function(value, element, params) {
if ($(params).val() === "")
    return true;

if (!/Invalid|NaN/.test(new Date(value))) {
    return new Date(value) > new Date($(params).val());

        $("#dateOfBirth").datepicker(
    $.extend({}, $.datepicker.regional['en-GB'], dateOptionsDOB));

Thank you for spending time to read through my code.Code seems to work after incorporating your suggestions. Bingo! :)... most of my time was consumed in finding additional methods for validator and also en-GB formatting for UI widgets. I should have removed date:true rule :)

Kudos for this diagram and regex! Is it generated? Could you tell us what's the name of the tool if it is?

It always returns a date even if I enter an invalid date.

Is there one for mm/dd/yyyy format?

cusman, in that case i'd use moment.js

Simplest and functional solution. Thanks.

But you need JQuery UI.

Just like you've said - you don't need plugins. This simply works. If input is false, it throws exception. Thanks a lot :)

What if you want to parse hours and minutes?
dinesh kandpal over 6 years

when you are validating date in ''DD/MM/YYYY" Does it also include dateFormat : "dd-mm-yy" and dd.mm.yy ???

Impressive! This even copes with the 100 and 400 year leap year changes.

this not work if you write 12/13/1991 this shows as a fine date when a month 13th not exist
izstas over 6 years

This function is not designed to validate the date. The OP is already using a dateITA validator, and this function just aids in the implementation of additional dateGreaterThan and dateLessThan validators.

If you add OR, will do the trick: return this.optional(element) || moment(value,"DD/MM/YYYY").isValid() || moment(value,"DD-MM-YYYY").isValid();

This will fail for : moment(1,"DD/MM/YYYY").isValid(); moment will return true .

One should not directly edit jQuery validate core files. It is dangerous
