Check If A Date Is Valid
Oct 14, 2001Say I have three variables: month, year and day. How do I check whether they form a valid date, i.e. not "Februrary 31 1999"?

View 5 RepliesI've been doing a bit of research and haven't found anything too easy. Can anyone point me to an article that has a function written in javascript that validates that a date that has been submitted via a form that it is a valid date?

Each time a new year or a month is selected the menu's are updated to allow only valid dates. Its only just been finished and could probably use commenting more, but im always open to suggestions, advice and criticism.

One of the fields that can be filled in is a "Release date" field, where a correct release date can be filled in. The form uses dropdown boxes for selecting the date; this is much less confusing in terms of how to format the date than if one would just use a text input field. Here's a screen shot:[URL]..
I've been looking for a Javascript script that does three things:
1) Validate the entered date (i.e. no "31st of February" dates).
2) Check whether the date entered doesn't exceed today's date (so no release date in the future is allowed). This could be combined with PHP to find the today date.
3) If the "I don't know the release date" box is checked, simply skip the whole validation process (no need to validate something that won't be used).
I've been looking for Javascript code that does this, and I found a couple of scripts (like this one) [URL].. /date_validation.asp), but they all make use of text input fields where the user has to input it in a certain format (mm/dd/yyyy et cetera). This is not what I'm looking for, but having zero knowledge of Javascript I am completely unable to write my own code or adapt this code to what I want.
I already figured out the PHP that does all of the above, but I would also very much like to have some code that checks the date before the data is processed so that users who have made a mistake don't have to fill in the whole form a second time.
I try to make a script which check's input's value every time when value changes. There must be ready example somewhere, but I just could not found it. The value shoud be hex-color-value (like #FFFFFF), so script should check if the first character is # and after that only characters a-f, A-F and 0-9 are ok. I guess it goes something like this:
function checkHex(value) {
// if value string includes only characters # a-f A-F 0-9 value is ok
// else value is not ok
}
<input type="text" id="hex_input" onkeyup="checkHex(this)" />
I have an online shopping cart and some of the products are sold in boxes of 6. So I am trying to write some code that will alert the customer if they have entered a quantity that isn't some multiple of six.
I've tried using the modulus operator as well as dividing by 6 and then checking to see if the result is a whole number but inevitably the alert box pops up no matter what I enter.
This is what I'm trying to use now:
Is there a better way to check if the entered quantity is a multiple of 6?
So I have a new window document write which outputs all my data after validation into a new window, I have tried to write a button which will (when clicked) send that information to an email address. here is my code so far. i spent about 2 hours checking and playing around looking for errors couldnt find any. I think the problem is the function EmailForm and function subwrite. Is a button written into a new window a common thing to do? or is there another simpler way, however i want the user to be able to check to see if there data is valid and then click to send the email.

How do I verify that a given URL exist before actually loding it using

I do not know javascript but I just wanted to check to see if this is valid javascript across all browsers that support js.
<script type="text/javascript">
function locate(page)
{
thePage='http://www.domain.net/' +page
window.location=thePage

It works in IE, should I expect any problems in any other browser?
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.
I am trying to use the jquey datepicker. I want to show the date chosen by the user in a <span> element with a particular format. However my code maintains the default format. What am I doing wrong?

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]

I am building a custom validator. I don't want any suggestions on using a jQuery framework, i just want to ask a few question on how best to continue.
Code:
<script type="text/javascript">
//Validator Strings And Expressions.
var Letters = /^[A-Za-z]+$/;
[Code].....
This is the "on page" validation. This, as you can see calls functions held in an included file onkeyup. This all works well, also the username check ajax call works great. However I have 2 questions that I need to sort before this will work correctly.
1. Using M_USERNAME form as an example. If I start typing in there it will begin validating, which is great, However, if i typed in "matt_thomas" based on the validations, Empty:Pass, ValidChars:Fail, Range:Pass, Check:Pass.
So I know that it isn't empty, it's the correct length and it's not already in the DB. But it fails because of the "_". This should mean that I receive the error i have setup for that failure. But I don't. Because I don't stop on a Fail, I receive the success message of the last function.
So my question is; How Can I stop running any more functions when one fails?
2. Looking at the above code, How can I make sure that a submit will only work when ALL fields validate correctly?
I have a problem setting the default date of my jquery datepicker to the date that I retrieved from my database. I'm currently using the jquery datepicker linked to selects/ drop downs. I auto-fill my selects (month, day, year) from an external javascript. (fbDateTime.js)

Can anybody give me complete code and steps wherein i can implement the dtpicker in only "yyyy-mm-dd" format. i want the user to select the date using this dtpicker and the selected date should show in the textbox on the form.
