Best (and Easiest) Way To Test That A "date String" (mm/dd/yyyy) Is Valid
Dec 3, 2006
Just looking for the simplest. right now my perl script returns an
error messge to the user if the date string is invalid. would like to
do this before accessing the server.
My question is.. I have one text box there user types the date as follows (d-m-yy) 5-4-09 or 15-3-94 how can i convert them into exact (dd-mm-yyyy) 05-04-2009 or 15-03-1994 is there any 'javascript' code to convert the given date into my desired formt...
I'm writing a form validation function and would like to verify that a field only contains alphanumeric characters. How should I structure that statement? the following seems logical but doesn't work;
I'm using this validation plugin alidation/and it is great.However, it rejects dates like 07-14-2009 as invalid. Is there someway to add a list of valid formats?If not, should I write my own method to match that particlar format?
I'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?
The following script generates three SELECT menu's... one for days one for months and one for years. 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.
I am trying to use JavaScript in conjuntion with html to display a table of sortable cities, states and dates. The dates are my problem. I am a novice and was given this code. But it seems to sort in European style, yyyy/mm/dd. I need it to sort mm/dd/yyy, which i am told is US style. I have placed a page here ([URL]) to let you see the code at work. This page has the code on it in text also. I do not mind posting the code hgere also if you prefer.
I'm working on a website where users can add films to a film directory through a form. 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.
It should allow 1 or two digits for the day of the month, then a separating character (" ", "/" or "-"), then 1 or two digits for the month, then 2 or 4 digits for the year.
Unfortunately it will accept anything above 2 digits for the year, which I understand why is happening but don't know how to fix!
why the string comparison test doesn't work in this javascript function? It works if you use just text between the currentItem div tags, but not when you use html for an image. I even tried to use iso characters instead of angle brackets, as in "<img src=expand.png></img>" and still no dice. Why not?
I have pulled a date from our database in the form of mm/dd/yyyy, and would like to convert this to a Date object type. To do this, I have parsed the string to switch it to the following format yyyy,mm,dd. I have already created a new Date variable using the following: Date reqDate = new Date(2010,10,14) and had no issues. However, if I do the following: Date reqConvert = new Date (reqDate3) where reqdate3 = 2010,11,15 I get the following error: "Invalid Date".
I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).
I'm looking for the easiest way to change HTML inside DIV element of the page which will work in all browsers. I've googled and found solution, but people say it works only with IE.
I've read view articles about how to dynamically recieve data from server with Ajax, but they are too complicated for me. I wonder what technique do you use? Which one is the easiest one?

function start_to_enroll(){ var miliDay = 86400000; var startField = document.getElementById('start_date'); var enrollField = document.getElementById('enroll_date');
I am working with an API that delivers a date like this: P20DT9H1M14S Standing for a period of 20 days, and time of 9 hours, 1 minute, and 14 seconds. I am trying to figure out how to convert the P20DT9H1M14S to this: 20 days, 9 hours, 1 minute, and 14 seconds.
