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:
View 2 RepliesI 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 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();

A question for a jQuery expert. I'm more familiar with Prototype, but I've been using jQuery a lot recently and needed to find out how something is done, jQuery style Prototype has a rather handy wrap() function which lets you wrap an existing function within another function. It lets you attach code to be executed before or after an existing function is called.[URL]...

I need to calculate age by using this date of birth and should show alert if age is less than 5 years.
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:
View 3 Replies View RelatedI 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?

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

I came across Marijn's helper function again called forEach. It does just what it sounds like it does, and is one of those things one would consider adding to their own personal little library like getElementsByClassName...My question is, I've heard/seen that Mozilla (and only Mozilla at this point) indeed HAVE a forEach function, and I do most of my beginning testing in a recent-stable Mozilla browser, so I'm not 100% sure but I think the Mozilla forEach might work... what happens if I write my own and I keep the name?
So if there's some default forEach that the browser natively understands, and then I have a function in my lib that has the same name, does mine take precedence over the native one, or not? Is it just safer giving libraries slightly weird names so new in-built functions can't possibly interfere?So also, if later browsers end up implementing the newer Javascript (2?) that as I hear, will implement a getElementsByClassName, would this break, or ignore, everyone's pre-made getElementsByClassName, assuming they are called the same name?

modifying an existing function which controls the highlighted states of a multi level js accordion menu. I have had to use javascript due to certain css elements not working in safari browsers.My problem is due to the multi level aspect as when a sub link is clicked, the parent link above it then deselects. I need the parent link to stay active when its sub links are clicked and only deselects when a link outside of that list is clicked upon.I understand the theory of adding a conditional statement but simply don't know how to apply it correctly within the functionHere is the existing function which tells a link to be active or selected:var Lst;
function CngClass(obj){
if (Lst) Lst.className='.topnav';
obj.className='selected';

I have an existing JavaScript function that cycles through a bunch of colors depending on how many clicks of the mouse made.The all works fine, but I have since my code a little more complex, so now the colors are remembered once the user goes back to this page.. this is done with PHP and mySQL. The problem is that, once they go back the color may be red (2nd in the cycle), meaning next click they would expect to see orange, but the click counter is back to 0 so they actually see green.The code is:
Code:
<script type="text/javascript">

I'm trying to add a unix timestamp into an exisiting function, but am uncertain how you add the variable. I searched the boards here, and came across this example to convert a date to unix in javascript. var date3 = new Date(Date.parse("21 May 2009 10:03:20")); And I'm trying to add it to this: flashobj3.addVariable ("targetTime", $date3);

what can i do with javascript to get this date?
The problem is, the date displays correctly as a complete date in an
alert box but when I try to build the date from the components (i.e
d.getMonth() etc...) the result is an incorrect date.
How can the date be both correct and incorrect at the same time? The
intial alert(d); displays correctly, but the alert(t + "/" + m + "/" +
y); does not. Code:
All I'm trying to do is put the current date into a website that I'm currently working on. Here's the code I'm using:
<script language="javascript">
now=new Date()
month=now.getMonth()+1
today=now.getDate()
year=now.getYear()
current=today+"/"+ month+"/"+year
document.write(current)
</script>
The only problem I'm experiencing is that the date is coming out as 3/6/105.
Where is the "1" coming from in the year? How can I get rid of it??
Another newbie question here, I'm sure. I'm trying to modify an existing form with an existing validation scheme. I have to put in something so that the phone field that is entered actually contains numbers. There is no need for dashes, parens or any other divider, but we don't want to exclude them either.
I have gotten as far as this: [URL]..110620_1a.html (new isPhone function that doesn't break anything added at lines 119 - 127) When I try to add the call for the checking however, the entire checking scheme breaks, and the form just executes: [URL]...._110620_1.html (Added code is at lines 190-198)
After reading section 15.9.1.1 the ECMAScript Language Specifications I
see that the date range for the Date function is +/- 100,000,000 days
from 01 Jan 1970. This is called an extrapolated Gregorian calendar.
Since the Gregorian calendar did not begin until 15 Oct 1582 what is
the purpose of dates before that date? Wouldn't any computation prior
to that date be meaningless or am I missing something?
The reason I ask is that I have created a date calculator at my web
site. I don't want it to do computations with dates that have no
meaning.
Columbus discovered america on 12 Oct 1492. This must have been with
the Julian Calendar. If I used the Date function to see how many days
it was from that date until now would it be correct?
I am creating a form with a date field. i want the date field to autofill onload. The form will then be submitted to a database. My question then, is should I auto fill the date with JS from the users computer, or with PHP from the server that contains the DB, where the report will be stored?
