Date Comparison Validation

Sep 29, 2005

I have 2 textbox for Date input: Start Date and End Date I have javascript onsubmit="return fieldCheck()" to check all the required fields are not empty.

My problem is that i want to throw below javascript to check that End Date cannot be earlier than the Start Date. It works if both dates are in the same month, and if they are different month or day, then it's not working properly

d1_str = document.form.txtEndDate.value;
d2_str = document.form.txtStartDate.value;

d1 = new Date(d1_str.split('/')[2],d1_str.split('/')[1],d1_str.split('/')[0]);
d2 = new Date(d2_str.split('/')[2],d2_str.split('/')[1],d2_str.split('/')[0]);

if (d1.getTime()<d2.getTime()) {
emptyfields += "
End Date can't be earlier than Start Date" ; //this is the error msg

Date Comparison Based On Selected Date

Jan 13, 2011

I have a drop down menu where people can select a month, day and year. Based on their selection, I want to show them an image.

If their selection is >= July 26, 2010 but <= July 25, 2011, show the red image;
If their selection is >= July 26, 2011 but <= July 25, 2012, show the white image;
If their selection is >= July 26, 2012 but <= July 25, 2013, show the blue image;
If their selection is >= July 26, 2013 but <= July 25, 2014, show the yellow image;

I don't know how to compare a selected date to a range of dates like this.

Date Comparison In Months - 2 User Input To Ensure That Date2 Is At Least 2 Months After Date1

Jul 20, 2009

how to compare 2 user input dates (say Date1 and Date2) in dd/mm/yyyy format, to ensure that Date2 is at least 2 months after Date1. Comparing them in days is simple but I'm not sure where to start on months, taking into account differing number of days per month and leap years. e.g 01/01/2009 - 28/02/2009 would equal 2 months.

Numeric Date Validation

Jul 23, 2005

It has appeared that ancient sources give a method for Numeric Date
Validation that involves numerous tests to determine month length;
versions are often posted by incomers here. That sort of code seems
unnecessarily long.

For some while, the following approach has been given here :-

function ValidDate(y, m, d) { // m = 0..11 ; y m d integers, y!=0
with (new Date(y, m, d))
return (getMonth()==m && getDate()==d) }

and it may remain the shortest code. But it does require, in every
case, the creation and disposal of a Date Object.

The following is about 50% longer in code, but about four times faster
in my system - and it seems to be right, too.

function DateOK(Y, M, D) {
return D>0 && (D<=[,31,28,31,30,31,30,31,31,30,31,30,31][M] ||
D==29 && M==2 && Y%4==0 && (Y%100>0 || Y%400==0) ) }

Note that checking for 1 <= M <= 12 is inherent, and that the Leapness
of the year is only determined if the date given is February 29th.

Also, it is easy to use only the quadrennial rule if it is certain that
dates are in 1901-2099, or only two rules for 2001-2399.

JScript Date Validation

Dec 27, 2007

I have a form input that takes a date in the format MM/DD/YYYY.

I would like to validate this input using Javascript in two fashions:

1. I need to check that the format of the input is 'MM/DD/YYYY' with the month day and year being numeric

2. I need to also check that the 'MM/DD/YYYY' being input is later than today + 2 days (i.e. if today is 12/27/07, then the input must be 12/29/07 or greater)

JavaScript Date Validation

Feb 8, 2003

Recently while messing with dates, I noticed an odd quirk in javascript with new Date(), i.e. if someone enters an invalid date, such as 2/29/2003, javascript creates the new date as 3/1/2003.

Having a look around, I couldn't find any scripts that took advantage of this for the sake of date validation... probably someone here has done this before, but I'll post it anyway.

The idea is that if javascript creates a new Date() with a different month, then obviously the date entered is not valid. Most of the scripts I saw used some math to divide by leap year, yadda yadda yadda, but with this feature (?) of javascript, it seems unnecessary.

Right now this code only validates mm/dd/yyyy, but it should be easy to modify to support other formats:

function isDate(sDate) {
var re = /^d{1,2}/d{1,2}/d{4}$/
if (re.test(sDate)) {
var dArr = sDate.split("/");
var d = new Date(sDate);
return d.getMonth() + 1 == dArr[0] && d.getDate() == dArr[1] && d.getFullYear() == dArr[2];
else {
return false;

Here's a shorter version that works if you pass in the values separately:

function isDate(mm,dd,yyyy) {
var d = new Date(mm + "/" + dd + "/" + yyyy);
return d.getMonth() + 1 == mm && d.getDate() == dd && d.getFullYear() == yyyy;

Date Validation - 2 Scripts

Dec 6, 2005

I have a $credit refund page that runs 2 date scripts. The first to input and format today's date for the date the form is sent:

function prefileDate(){
todaysDate = new Date;

month = todaysDate.getMonth();
if(month < 10){
month = "0" + (month +1);
} else { month++;}

day = todaysDate.getDate();
if(day < 10){
day = "0" + day;}

year = todaysDate.getYear();

document.getElementById("Date").value = month + "/" + day + "/" + year; }

The second script needs to run on 5 other date fields as an onblur call - BUT - I need this to also validate that the date entered is an older date that the "today's date" referred to in the above script. EX: the form is being sent on 12/5/05. the expdate below needs to be 12/6/05 or later. Code:

Date Of Birth Validation - JS Or PHP?

Sep 1, 2011

I was wondering if there is possibly an "onBlurr" or "onChange" way I can check using JavaScript if a Birth date is correct I've seen a couple but I have a pretty simplistic way about how I want to get it done.Basically what I would like to do is check the months and check if they've entered an incorrect date for them (I will be using the 3 drop down boxes method).

so if a users selects 30-31 for feb i want it to check the minute its changed for either one in order to notify the user that its an invalid birth date, which would apply for all months totalling 30 days.also the same for the leap year of feb if its 29 but the year is not divisible by 4 then the date is still invalid

Date Entry Validation Gets Stuck?

Jun 23, 2011

I have a CF application that accepts two dates. The first date - Out Date - is required. The second date - Return Date - is optional, but if populated, must be equal to or greater than the Out Date. Here's the screen & code:

<script type="text/javascript">
function compareDate()
{ if(document.editleave.temp_ret_date.value != "01/01/0001")[code]....

Everything works fine....EXCEPT...if the Return Date is invalid, I cannot click on the calendar box to select a date (or open another browser session). Basically, IE is locked up until the user manually types in a valid date.This ain't good.I want to be able to trap the error, just like I have, but I still want the calendar selection box to be usable.Is it possible to "reset" the error condition after the intial warning to only trigger on the onSubmit parameter?

Cfinput With Date Validation - Catch Changes ?

Jun 12, 2010

I have a cfform with the following (partial) structure:


I'm written a simple script that sees if the user has entered a start date in the StartDate field, and automatically populates the EndDate field with that value:


This script works just fine when entering values directly into the input field. However, it does NOT work when using the Calendar popup that ColdFusion helpfully adds when using date validation. When you click on the calendar icon to the right of the input field, a calendar popup appears; once you click on a date, the date is entered into the field. Unfortunately, JavaScript does not recognize that anything has happened.

This is problematic because the date popup is the easiest way to enter a valid date, and the one that I automatically use, and which I assume that other users will gravitate to as well.

Date Validation Function (Month / Day And Year)

Apr 17, 2003

I am working on a series of functions that I keep getting asked about. The following three scripts do this:
--Date Validation
--Calculate Difference Between Dates
--Date Addition or Subtraction

I am sure that these have been done before, but I just filled the last 20 minutes by coding these. I only did a quick browser test, nothing extensive.
//Date Validation
function DateValid(mo, dy, yr){
TheDate = mo+"/"+dy+"/"+yr;
Date1 = new Date(TheDate)

String Comparison

Jun 1, 2007

How would one go about comparing 2 strings one of which may contain
special entities (eg "cassť" and "cassť")?

I tried to find a way to take the second string and do a replace
whenever such entities are encountered but this implies creating some
sort of lookup table containing not all but a good number of entity
codes. Unless I am mistaken, javascript does not any function to replace
an entity-infested string with a decoded string, pretty much like php's
html_entity_decode. Another way, probably better (but I don't know),
would be to encode the first string.

IE GetElementByID Or String Comparison?

Feb 9, 2009

I have this method: function rbc_init() {

var choice = document.getElementById('choiceKey6').value;
var searcher = document.getElementById('searchText').value;
if (choice == "Services")
var script = '/site/includes/az_search_results.php';


choiceKey6 is a drop down menu with the values "Services", "Documents", "Downloads", "Frequently Asked Questions". I've named it strangely because of the bug that causes IE's getElementByID to search both ID's and names. SearchText is just a textbox, but it is irrelevant to my problem.

My problem is that in firefox this works as expected, the string comparisons work and the code in the if statements is executed as expected. In internet explorer however, the algorithm always defaults to the else statement at the end. What have I done wrong? argh.

String Comparison And Extraction

Sep 19, 2006

I have a problem with Javascript, I need to do something fairly complicated and I'm not sure how. first let me explain what I am trying to do.

I need a user to be able to enter a single word in a text form on a page. i then need to seperate every character in that string to create new variables (example: var charater1 = string.charAt(0)) there are ten characters in total.

I then need to compare the character to find the appropriate integer number for it, for example A would equal the integer number 1. once I have converted all ten characters I then need to write them to a file, something like a text file or the like.
