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

I have a function I call to see if people leave form fields empty. I have been asked by a client to check to make sure of the person's date of birth as well. They gave me the script, however, I am unsure how to do implement it. How do I add this to my existing checks? Code:

I need to validate the DOB selected by the user, user should be 13 years of age (Current date - 13) to complete the information on the page. If the user is not 13 then user will be redirected to an error page. I have written a function (below) but i know there must be a much better way of doing this. Function receives 3 parameters; day, month, and year selected by the user for DOB. Code:

I have a form where we are capturing the Members Children information. I want to insert age in years to a field within this table by calculating age from Date of Birth (DOB). DOB format is mm/dd/yyyy and is a datetime data type in SQL. The DOB is added by the member while registering their child. Is there an onchange script that I could use here.
Is it possible to auto populate a field from an other field within the same form? Does anyone have any code samples that I could use?

<script type="text/javascript">
This script when the year is selected chooses 2011-2030 but I want like 1900-2011 How do I fix this and then how would I make sure that it isn't blank and then sends this data to one field in my database called "dob" in form "0000-00-00"..

I have a date of birth drop down for 'Day', 'Month' and a text field for Year.
How can I get the select value of the drop down and year text field into a single text field, separated by '-'?
The single text field would need to update if someone changed the drop down / year selections.

how can I make it so whenever I select a different year or different month it doesn't reset the Day option back to option 1 (the option that's called Day), unless of course you select a day then change the month that doesn't contain that day (like if u choose january 31 and then select february, it obviously must reset).
For example, say you choose january and then the day 20. Now if you select february, I do not want it to reset the day back to "Day"
Instead, I want to make it so it stays on the day 20 since there is a 20th of February. But still, I want it to eliminate the options 29, 30 and 31.
Here is a working example of the drop downs http://ckeanedesign.t35.com/dob2.html
Here is the HTML code I am experimenting with (thanks to felgall)

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.

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)

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;
}

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:

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
}

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:
9974
<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?

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

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.
<script>
//Date Validation
function DateValid(mo, dy, yr){
TheDate = mo+"/"+dy+"/"+yr;
Date1 = new Date(TheDate)
D=Date1.getDate();
M=Date1.getMonth()+1;
Y=Date1.getYear();

I have a start date and end date text boxs. What I would like to achieve is when a submit button is clicked all the available dates between start and end dates should be displayed together with 3 check boxes next to each date (please see below). I am just wondering whether that'sachievablewith jquery, and if so, how I might be able to implement this.

I have added a booking form to a website with belongs to fastbooking.You can see a temporary website here. http:[url]....It works perfectly fine in Mozilla Firefox, Google Chrome, Opera and Safari but it does not load on Internet Explorer.On the other browsers the form loads todays date and the year is generated but on IE the date stays on 01-01 and no year is generated.I'm using wordpress as a cms.I think the code that is not loading is <body onLoad='start();'>But I'm not sure. The code of the year is
<select name='fromyear' class="input" onChange='update_departure();'>
<option value="0"></option>
</select> But since it's no just the year I assume its the onload code.
I tried to add the onload to the header function like this
<body onLoad='start();' <?php if(function_exists('body_class')) body_class(); ?>>
So now wordpress generates the following code when it loads the page
<body onLoad='start();' class="home page page-id-6 page-template page-template-default logged-in">
But sadly the date still does no load on Internet Explorer.

We have a little callendar on our website. I have set the format of the date to "dd-mm-y" because I want the date to be saved europian, not american. When comfirming the form, the date is saved as 0000-00-00. The date shows correctly on the form itself. I have two scripts: Calendar.js and Calendar-en-GB.js. Calendar-en-GB.js contains the 'settings'. (Including date format). I can't figure out the problem and thought maybe one of you could. I have uploaded the scripts in one .zip file: [URL]
