## Passing Server Time - Countdown Timer That Currently Uses The Client's System Time To Calculate The Countdown

Feb 4, 2011

I'm using a javascript-based countdown timer that currently uses the client's system time to calculate the countdown. I assume that this line of code is where this is performed:

Code:

I'm trying to make the script use server time instead as some people may have wrong dates/times set or live in different time zones etc.

So what I did was use a bit of php:

PHP Code:

This gives a result but now the countdown is 30 days off. I am testing on my local xampp server (which also uses system time) so there should be no discrepancy. I also tried adding

Code:

But no difference.

I can post the whole script if required but it is reasonably long.

## Calculate And Display TOTAL Time On Website?

Mar 25, 2009

I have a Javascript that calculates and displays how long, in minutes and seconds a user has been in online(Google Gears development) mode on a given web page. I need however, to modify the script so that it calculates and displays how long the user has been online on the web site. For e.g. on page 1 for 2 minutes 12 seconds. Moves to page 2 - total time on page 1 and 2= 4 minutes 13 seconds. My script (see below) starts a second counter then converts that to minutes and seconds. I have tried passing the secVar0 variable in the url but that comes back "undefined".

Code:

if(request.responseText != "" && request.responseText.indexOf("404 Page not found") == -1)
{
c=0;

## Script With Document.write Inside Iframe Hangs First Time, Works Second Time (in IE)?

Dec 22, 2010

I have put together a script which does this:

1. Make ajax request (via getHTTPObject(), no libraries is used)

2. Create an iframe with script, src is "blank.html".

3. use iframe.document.write() to execute scripts (inkluding document.write based scripts) in the iframe.

4. call parent window's document to clone the iframe content.

5. Append the content clone to parent body.

Works like a charm in all browsers but IE, where every version - including IE9 beta - hangs on iframeWindow.document.close() with empty cache, leaving the window/tab unresponsible. When I force quit, restart and load the page again (now in cache) it works.What I've tried already:

* called the ajax request callback manually with string instead of request.responseText - it works even with empty cache here.Removed document.close() - resulting in scripts in iframe not executing at all (again, only with empty cache, cached pages works fine).

* Tested to make the ajax request synchronous - no difference.

Console.log trace:

Code:
append() begin
unlimited-scroll.js:160 install() begin
unlimited-scroll.js:194 iframe begin[code].....

## Automating Text To Change Daily At Specific Time To Website Viewers Time?

Sep 17, 2011

I do pretty much all the computer related tasks, which includes computer system repair, audio/video editing, cd/dvd printing and duplication, document format and creation, etc etc. But when it comes to HTML (or other codes) I know very little. But we needed a website, so I use Homestead hosting and the Homestead (offline) Site Builder program.

Anyway, inside the sight builder program, they have the option to insert HTML Snippets. Which I use for various objects, off site tools, and other. But now I need to do something for which I have not been able to find a "premade" html code object, that can perform the task desired. I have searched and searched google and went through many sites, including this one. I have tried to take some codes which I thought I could alter to make it perform, but they just wouldn't work for what I needed them to do.

I need a code that will automate a "specific text message" to change daily, and to schedule a "different specific text message" to appear each day. I need to be able to schedule each days "texts" at the very least 31 days in advance. In other words, I need to make an array (I think that's what it is called) for the entire month:

Day 1 "today's text 1"
Day 2 "today's text 2"
Day 3 "today's text 3"

[code]....

If were possible to make an "array" that would go six months out (or more) that would be very helpful! But the longest that I have seen is one month at a time, so that may be as long as they go, but I'm not sure.On top of all of this, I need these changes to be performed at a specific time of the day. I would like them to be preformed at sunset everyday, but I don't think there is anyway to direct the code to look at like [URL] sunset times or such. So if I can at least choose a specific hour, like 8:00 pm, that will work, I will just have to adjust this every once in a while.

However, I don't want it to change just at 8:00pm in my timezone. I need it to change at 8:00pm according to the website viewers timezone. Is there a way to make the code "look" at the users computer and "get their time" and use that to adjust what text is displayed? In other words, I live in Indiana USA. If someone in Australia looked up the webpage on the 15th day of the month, but it was 9:00pm Their Time. The text I need to be displayed should be for "Day 16" from the array.

## Populate Select Boxes - Create Events, With A Start Time And An End Time?

Jun 3, 2009

I'd like some direction on creating a small piece of Javascript that will populate my <select> boxes.Basically, I have a form for users to create events, with a start time and an end time. (These are the two select boxes).For example:

Code:
<select id="startTime">
<option value="12:00AM">12:00AM</option>
<option value="12:15AM">12:15AM</option>
etc.....
</select>

What I am trying to do is:

1) Have times populated in 15 minute incrementals from 12:00AM to 11:45PM

2) Have some type of "error checking" available to where the End Time must be after the start time. It would be nice for the script to automatically change the end time field to a time that is after the start time.

## Real-time Countdown (count From Start To End Time)

May 30, 2011

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.
