JavaScript - Grey Box Pop Up First Time Only

Hello everybody,

how can i grey out a whole page, and focus attention on a div only?
are there any good scripts?

please help.

EDIT:

actually what i want to do is: click a button grey out all my page and show a loading gif load, thru ajax, content from external source turn off grey and loading gif update current page content.

Hi All,

I m newbie on JavaScript Coding.

I have Form where the there are 4 radio buttons.

Requirement is OnClick of Each radio buttons, some Div must Greyed out.

<input type="radio" name="cf_basic_type" value="Apartment" checked="checked" />Apartment
<input type="radio" name="cf_basic_type" value="Villa" />Villa
<input type="radio" name="cf_basic_type" value="Independant" />Independant house
<input type="radio" name="cf_basic_type" value="Plot" />Plot</div>

and Grey Part of Form is:

Area Size:<input type="text" name="cf_area_size" id="cf_area_size" /></div>
Plot Size:<input type="text" name="cf_area_length" id="cf_area_length" />
<input type="text" name="cf_area_width" id="cf_area_width" />


so for Plot radio selected the 'Area Size' must be greyed out but when others radio button selected is must be active

For Apartment radio selected or Villa radio selected, Plot Size must be greyed out.

Hope that makes clear.... Its very Urgent kindly help me with this..

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

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 brothers and sisters,

My first post here. I am trying to do a self-test system for my small company, everything is going smoothly so far however, I am facing some problem with setting a cut off time for doing the test. For example, my staff could not go in to the system after 8pm. Anyone had any idea on how to do it?? I have only some basic knowledge of php which I learn in school thus setting time limit might be too advance for me thus need you guys help.

Thank alot

Hi,

I have very little JS knowledge, on a scale of 1 - 10 I would give me a 1, so apologies if I have this completely backwards.

AIM:

I have a form that takes in times a person was doing an activity, and you can enter multiple times & activities in one go.

e.g.

Person A | Lunch | 12:00 - 13:00
| Meeting | 13:30 - 14:00


I need the JS to validate that Activity B (Meeting in the above example) does not overlap with Activity A (Lunch in the above example). It also needs to check this for all activity's so that none overlap with each other else output error.

I have managed to do this server side in PHP and will include the code as it may help show what I am trying to do better than Im explaining.


PHP Code

Code:

	$Code = $_POST['code'];
	$NumberofCodes = count($Code);
	$Start = array();
	$_POST['starthr'] = array_values($_POST['starthr']);
	$_POST['startmin'] = array_values($_POST['startmin']);
	$i = 0;
	foreach($_POST['starthr'] as $key1 => $value1) {
	$Start[(int)$i] = $_POST['starthr'][$key1] .":". $_POST['startmin'][$key1];
	$i++;
	}
	$Stop = array();
	$_POST['stophr'] = array_values($_POST['stophr']);
	$_POST['stopmin'] = array_values($_POST['stopmin']);
	$i = 0;
	foreach($_POST['stophr'] as $key1 => $value1) {
	$Stop[(int)$i] = $_POST['stophr'][$key1] .":". $_POST['stopmin'][$key1];
	$i++;
	}
		
	$i = 0;
	$j = 1;
	
	while ($i < $NumberofCodes){
		while(($j-1) < $NumberofCodes){
		
	if (($Start[$j] > $Start[$i] && $Start[$j] < $Stop[$i]) || ($Stop[$j] > $Start[$i] && $Stop[$j] <= $Stop[$i])) 
	{
		//Stop form executing and provide error information.
	}
	$j++;
	}
	$i++;
	}

JS Code (What I could manage)

Code:

	var i = 0;
	var j = 1;
	var Start = new Array();
	var Stop = new Array();
	var aa = new Array();
	var bb = new Array();
	
	while (i < counter){
		while((j-1) < counter){
	Start[i] = document.myform.elements('starthr['+i+']').value + ":" + document.myform.elements('startmin['+i+']').value;
	Stop[i] = document.myform.elements('stophr['+i+']').value + ":" + document.myform.elements('stopmin['+i+']').value;
	var a = toDate(Start[i],"h:m")
	var b = toDate(Stop[i],"h:m")
	
	aa[i] = a;
	bb[i] = b;
	
	
	function toDate(dStr,format) {
			var now = new Date();
	 		now.setHours(dStr.substr(0,dStr.indexOf(":")));
			now.setMinutes(dStr.substr(dStr.indexOf(":")+1));
			now.setSeconds(0);
		return now;
	
}	
	if ((aa[j] > aa[i] && aa[j] < bb[i]) || (bb[j] > aa[i] && bb[j] <= bb[i])) 
	{
		//Fail validation
	}
	else
	{
	        //Pass Validation
	}
	j++;
	}
	i++;
	}

Any help on this would great.

Hi,

There are two text boxes in a HTML form. The first text box takes the time when the user starts to work on a project. The second box takes the time when the user stops working on that project.

Now, I would like to calculate the total time worked on that project for that user. That is (stop time - start time). I tried few things without success.

Any help will be appreciated.

I got this script and I'm trying to get the EST hour but I have a big concern that it doesn't work, can somebody help me and tell me if it works by him (it should display "15" even if he doesn't have est time) and if not plaese tell me why. Thank you. Try it he http://jsfiddle.net/fqz37/

Code:

// function to calculate local time
// in a different city
// given the city's UTC offset
function calcTime(city, offset) {

    // create Date object for current location
    d = new Date();

    // convert to msec
    // add local time zone offset 
    // get UTC time in msec
    utc = d.getHours() + (d.getTimezoneOffset() * 60000);

    // create new Date object for different city
    // using supplied offset
    nd = d.getHours(utc + (3600000*offset));

    // return time as a string
    return nd.toLocaleString();

}

// get NY time
ny=(calcTime('', '-5'));

document.write (ny);
