JavaScript - How Can I Add The Time To My Page Update?

I've seen a few people elsewhere with a similar problem, but couldn't get the solutions to work for my individual problems.

I am currently trying to display a gallery of images using Lightbox, and a contact form in a different modal window using a different script.

Here is the URL, so you can view the source.

Clicking 'contact' opens the Contact window, which currently works, and clicking the images SHOULD open lightbox but doesn't. If I shuffle the code around, I can get Lightbox to work but the contact window then breaks.

If someone could provide just the code I should replace mine with so I can just copy and paste it in, that would be great because I don't know anything about javascript and struggled to follow the instructions for this I found elsewhere. However any help is appreciated! Thanks in advance. (:

(Just in case you notice - please excuse my use of tables in the coding, this is just temporary)

This may be a stupid question, but is there a way to have a page refreshed at a specific time of day?
I have made up a page I set as my browser's home page, an electronic Page-A-Day calendar. If I am working on the computer overnight I would like this page to refresh autotically at midnight. I have seen all sorts of posts that describe how to refresh after a certain amount of time has passed, but nothing for what I would like to do.

For those interested the code i have for the webpage in in the attached file.

I've a web page when a user logs in, it will have a link that shows the "username" and a link for "logout".

After the user logs out, the "username" and the "logout" links will change to "login" and "register" links, respectively.

The page uses javascript to check a user cookie, if the user cookie exists, it will show the "username" link and the link for "logout". If no user cookie exists, "login" and "register" links will replace the "username" and "logout" links.

Here's the problem: When a user who has log in, clicks the "logout" link, a perl script will delete the user cookie, and redirects back to the same page. The page does not show "login" and "register" links AUTOMATICALLY. Both links will appear ONLY after the user MANUALLY Refreshes the page.

It appears that I need a system to refresh the page automacally ONLY one time. How can this be done?

I am current building an information database for the company I work at...basically just a place for employees to get information and answers from. It is all hosted on a local server and I can only use javascript, html, and css. Ive got everything made there is just one thing i want to add to it. basically an "alerts and updates" page that only some people can edit without having to know html so if im not there they can post important updates. no computers have access to the internet so I did try some rich text editors but none of them worked. the lay out I'm going for is kind of like this.
------------------------------------
Alerts and Updates

Click on links to show updates: update 1 * update 2 * update 3 * update 4

stuff goes in the update

[edit button]
-------------------------------------
you click edit it prompts you to login, bring up something to edit the text in that specific update you hit submit and it changes the info that was on there.

The update links are linked to a script i wrote that just display the info below so when the page loads you see whats in update 1 then you click update and it changes the content to the next one.

i dont know if there is any way to do this in javascript and html. any help or a good direction to start would be great...thanks.

how can i make a button disable when the page is loaded first time and then make it enable on the click of other button in javascript.

I am try to reduce the time taken to download my home page. I purchased a template and then just modified what I wanted. There is a script that calls 21 other scripts.

I am told if I combined all this scripts into one or two scripts, my download time would go down.

Help appreciated.

hi im using dhtml xgrid where i need to do validation for time ,(from-time and to-time i.e ind==1 and ind==2 ) to-time must be greater than from-time else i need to alert a message to-time must be greater than from-time.
can any one send me the code for it time format is[05:00].
Code:

var err_str="";
function validate_grid(value,id,ind)
	{
	$("#result").html(" ").show();
		if(ind==1 || ind==2)
		{
			var patt=/^([0][0-9]|[1][0-9]|[2][0-3])[:]{1}[0-5][0-9]$/;
			if(!patt.test(value))
			{
				mygrid.setCellTextStyle(id,ind,"background-color:yellow;");
				if(err_str!="")
					err_str+="\n"+(ind+1)+".Enter numbers and : only..";
				else
					err_str=(ind+1)+".Enter numbers and : only";
				return false;
			}
			else
			{
				mygrid.setCellTextStyle(id,ind,"background-color:white;");
				return true;
			}
		}
}

Hi

Code:

var err_str="";
function validate_grid(value,id,ind)
{
 $("#result").html(" ").show();
 if(ind==1 || ind==2)
  {
  var patt=/^([0][0-9]|[1][0-9]|[2][0-3])[:]{1}[0-5][0-9]$/;
  if(!patt.test(value))
   {
	mygrid.setCellTextStyle(id,ind,"background-color:yellow;");
	if(err_str!="")
		err_str+="\n"+(ind+1)+".Enter numbers and : only..";
	else
		err_str=(ind+1)+".Enter numbers and : only";
	return false;
   }
    else
      {
	mygrid.setCellTextStyle(id,ind,"background-color:white;");
	return true;
      }
  }
}
alert(err-str);

here ind==1 is from_time and ind==2 is to_time,i need to validate time as to_time must be always greater than from-time,if condition fails an alert msg should populate.time format is[05:00]as it is in string format im unable to do the validation for it.(ex:from-time=08:00 to-time=07:59 condition fails)

thank you.

I do have the countdown script (see link below) to display the time between current time and the date given in real-time.

However, I want to achieve to display the time difference between a given start and end time. Right now, it calculates from the current server time to the end time.

I want to be able to set up my own start time and end time.

Here is what I have:

thank you for help

I'm not really a Java writer, so I don't know how to do this myself, though I imagine it would be pretty simple.
I am looking to add a script to a webpage that allows users to input a time manually, and have it converted to GMT/Zulu time and display the converted time. I have seen a lot of time zone conversion scripts online, but they all just convert whatever the current system time is to another time zone. I am looking for a script that allows users to convert a time and show the zulu time, for times other than the current time. The time zone the inputed local time would be in is +4:30 (Kabul). I don't really care about style or aestehtics, just a simple script I can insert into a web page to have a time input field. The converted output time can appear in another field, a popup bubble, etc, again style isn't really an issue. It's really just to help people in my job who need to know what the GMT/Zulu time was for certain local times after the fact. One would think it shouldn't be that hard to just subtract 4:30 in your head, but apparently it is.

Sorry if just asking for code outright like this is frowned upon.

hi,

can some one help me how to get the time and date difference? given two time and date with the following format like in textbox A: 2011-05-03 17:35:47.0 and textbox B: 2011-05-03 16:35:47.0 then the output would be: 0 days, 1 hour, 0 minutes, 0 seconds

regards,
verve

This is my first time doing JavaScript I don't what I did wrong here, but the problem its not showing up the current date and time.
Code:

<script language = "JavaScript" type="text/javascript"> 
now = new Date(); 
localtime = now.toString();
 utctime = now.GMTString();
 document.wite("<b>localtime</b>" + localtime + "</br>");
 document.write("<b>utctime</b>" + utctime); 
 </script>

This is what supposed to look like


I have tried using different browser chrome,IE9,Maxtor, and Opera my OS is Win7

Hi - I have a date in my javascript like this:

Mon Dec 12 00:00:00 UTC+0430 2011

I need to convert it to a date without the offset (the +0430).

I actually changed my computer's timezone to generate this offset - we have uses placing orders on our site who don't use UTC and it's throwing our orders out as they need to select a delivery date but it's passing the date with the offset.

How do I convert a date to UTC time?

Thanks

Hi there! Well, I recently found the Image clock code, and I am loving it! But, I would like it to only display pacific time, not retrieve the time from a users browser.

Here's my code:
