JavaScript - Execute Command At A Certain Time

hi

From inside a javascript function i need to execute a vbscript sub routine.
You might be thinking why i can't do it in javascript. well i probably can but i am better at VBscript and it would be a lot easier.

Thanks

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

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.

Im alright with .php but not good at javascript at all.

this is the javascript code placed in the head tags of my page

function confirmation() {
var answer = confirm("Delete news item?")
if (answer){
window.location = "main.php?id=delete&note="+noteID+"&status=delete";
}
else{
alert("No action taken")
}
}

this is the .php that links to the javascript function
PHP Code:
if($this->admin){
                    echo '&nbsp;<a href="?id=edit&note='.$this->noteID.'&status=load" class="grey">[Edit]</a>'
                         .'<a href="" onclick="confirmation('.$row['noteID'].')" class="grey">[Delete]</a>'; } 



this is the .php code that executes if the url is status=delete
PHP Code:
                    // This displays if id = Delete A News & user=ADMIN
                    if( $id == "delete" && $session->isAdmin() ) {
                        echo '<div id="major_game_news_header">';
                        echo '<h1>DELETION OF NOTE</h1></div>';
                        $stat = $_GET['status'];
                        if($stat == "preview" && $session->isAdmin() ) {
                                $noteID = $_GET['note'];
                                echo '<div id="createnews">Are you sure? <a href="?id=delete&note={$noteID}&status=delete">'
                                    .'Yes</a>. <a href="main.php">No</a></div>';
                            }
                                if($stat == "delete" && $session->isAdmin() ) { $note->deleteNote();}
                        } 


this line in the third code snippet works perfect:
" PHP Code:
<a href="?id=delete&note={$noteID}&status=delete">Yes</a> 


"




I'm having great difficulty for the "window.location =...... " to navigate to the right url. It doesn't include the noteID which enables me to delete news items.

Any help would be greatly apreciated (:

Put this on a test page of yours and see what happens:

<script type="text/javascript" src="http://www.catpin.com/bumper_sticker3.php"></script>

Wherever that line is, when you view your web page, it should have a random quote.

It's using the same code that I had above (in post #2).

how would you put <script type="text/javascript" src="http://www.catpin.com/bumper_sticker3.php"></script> into a function for javascript to call this php file?

I am wondering if its possible to execute a JavaScript script as soon as the page is loaded? Perhaps a generic execution?
I tried this, but it didn't work:
Code:

<SCRIPT type="text/javascript">
	if (document.forms["form"]["quantitym"].value > '.$row['sizem'].') {
		alert ("The quantity for product $row['id'] is no longer available.");
	}
</SCRIPT>

<FORM action="updatecart.html" method="post" name="form">
	<DIV>
		<B>Medium:</B> <INPUT name="quantitym" value="'.$content['sizem'].'">
	</DIV>
</FORM>

This is for my shopping cart system. The idea is, the customer might have 4 items in his cart, but whilst he was shopping, someone might of bought the same item, result in only 3 being available, but his cart still says 4.

My solution to this is to make a script run through out his shopping when ever the cart items are listed and just prior payment execution, if the quantity he wants is no longer available, he will be alerted.

$row['sizem'] is PHP drawing how many items there are from my stock database. If the value of the INPUT exceeds this availability, JavaScript shall alert.

Does anyone know why it isn't alerting?

I have the following function:
Code:

function sonKare(sayac, oteki) {
  var vertical, horizontal = hangiYataySira(sayac, oteki), j, k,
  l, m, united, tekRakam, actualV = [], actualH = [],
  numaralar = [1, 2, 3, 4, 5, 6, 7, 8, 9], olmayanlar = [];
  if(ilkSefer === true) {
    vertical = hangiDikeySira(rakamlar.length);
    ilkSefer = false;
  }
  else {
    vertical = hangiDikeySira(rakamlar.length - 1);
  }
  for(j = 0; j <= vertical.length - 1; j ++ ) {
    if(rakamlar[vertical[j]] !== undefined)
    actualV.push(rakamlar[vertical[j]]);
  }
  for(k = 0; k <= horizontal.length - 1; k ++ ) {
    if(rakamlar[horizontal[k]] !== undefined)
    actualH.push(rakamlar[horizontal[k]]);
  }
  united = actualV.concat(actualH);
  //---- Olmayan rakamları bulan kısım ------------
  outer: for(l = 0; l <= numaralar.length - 1; l++) {
    for(m = 0; m <= united.length - 1; m++) {
      if(numaralar[l] === united[m])
      continue outer;
      if(m === united.length - 1 && numaralar[l] !== united[m])
      olmayanlar.push(numaralar[l]);
    }
  }
  //----------------------------------------------
  if(olmayanlar.length > 1 || olmayanlar.length === 0) {
    rakamlar = [];
    document.form1.buton.click(); // THIS LINE DOES NOT WORK SECOND TIME
  }
  else {
    $("_" + oteki + "_" + sayac).value = olmayanlar[0];
    rakamlar.push(olmayanlar[0]);
    sayac++;
    if(sayac === 10)
    return;
    else
    sonKare(sayac, oteki); //CALLS ITSELF
  }
}

This is a recursive function. As stated above there is a line which does not work for the second time. What I mean is, it works perfect for the first time and after function calls itself, it doesn't work. Javascript does execute the line above it but just disregards that document.form1.buton.click(); line. I use Firebug for debugging and I checked it many times, when that expression needs to be executed for the second time, JavaScript just ignores it and immediately goes at the end of the function... I just can't figure out why JS does such a thing?
p.s: Don't bother about weird variable names, they are not in English but in Turkish which is my native language

Sorry for the stupid question but i can't find a specific answer and i'm a newby. Here is a example of what i have:

<html>
<head>
<script type="text/javascript">

function open_win()

{window.open("http://www.microsoft.com","Window1","menubar=no,width=660,height=300,toolbar=no,scrollbars=yes");}

</script>
</head>
<body>
<form>
<input type=button value="Open Window" onclick="open_win()">
</form>
</body>

In stead of a button to open one window, i would like a numeric input box that asks "How many windows do you want to open?" then incorporate a loop command to loop the open_win() x amount of times.
Any help would be appreciated. Thanks

I am trying to use the LPR command inside a javascript to print a PDF file directly to the printer. Want just a simple webpage with a button which will print test.pdf when clicked.

lpr -S xxx.xxx.xxx.xxx -P print -o l C:\Users\xxxxxx\Desktop\test.pdf

I know very little when it comes to javascript. If you know of a better way to use the lpr command, please let me know.

I need to set something up so every X amount of second on a page it goes a certain command, and keeps resetting the counter after everytime and goes again. I thought of many of the timer commands I have found on Google but didn't know if this was the RIGHT way to do it since I want it to be a document command that repeats. If what is returned to the command is true instead of false it needs to be able to change location of the browser, so I didn't know if the timer commands I found were right or not.

Thanks.

How to set a js command using a variable?

var name = 'field';
var number = '1';

name.number(); doesn't work [when the js function is called field1]

I am using a set of dynamically created textareas and need to be able to reference each one by number.

Any thoughts?

Hi,

I have this code..

Code:

javascript:function showMore() {ProfileStream.getInstance().showMore(); setTimeout(showMore, 2000)}; showMore();

i want to loop it 10 times, but do not know how to do it. I have been told that the for var command is what I want, but I cannot get it to work.

Any help would be appreciated.
Thanks

Hello:

I have an ajax file to loads the content of another file into a div, here is the js code:

PHP Code:
<script type="text/javascript">
    function showUser(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getcar.php?q="+str,true);
xmlhttp.send();
}
</script> 


the file within xmlhttp (getcar.php) has other js codes that are to be executed once the file is loaded into the div. here is one of those files:

PHP Code:
<!-- loading, please wait message script begins-->
<div id="loading\" class=\"loading-invisible\" z-index: 999>
  <p><font color=\"black\" size='4'>one moment, please!</font> <font color=#218868> Auto Tech Pro &nbsp;&laquo;&nbsp;Initiating...&nbsp;&raquo;&nbsp;</font><br /><img border='0' src='images/spinnnnnn.gif' width='215px' height='206px'>
        
</div>
<script type=\"text/javascript\">
  document.getElementById(\"loading\").className = \"loading-visible\";
  var hideDiv = function(){document.getElementById(\"loading\").className = \"loading-invisible\";};
  var oldLoad = window.onload;
  var newLoad = oldLoad ? function(){hideDiv.call(this);oldLoad.call(this);} : hideDiv;
  window.onload = newLoad;

</script>

<!-- loading, please wait message script ends-->

<script type=\"text/javascript\" src=\"http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js\"></script>
      <script src=\"/AJAX/popBox1.2.0.js\" type=\"text/javascript\"></script>
    <link href=\"/AJAX/popBox1.2.0.css\" rel=\"stylesheet\" type=\"text/css\" />
 
    <script type=\"text/javascript\">
 
        $(document).ready(function () {
                $('#inputbox').popBox({width:550, newlineString: '<br/>' });
                  });     
    </script> 


this however is not working. If I open getcar.php independently of the ajax, the preceeding js codes work fine, but not once the ajax loads the file into div.

Any thoughts on how this is doable?

Hey guys, I scripted a javascript guessing game and I am not sure how I can configure the random number generator to only generate one number and then stop.

Here is my code:
Code:

<html>
<head>
<title>Guess it up! </title>
</head>
<body>
<center>
<BODY onLoad="GenerateNumber()">
<b><font size="5" ><u><b>Guess it up!<br></b></u>
<br >
<font size="3">
This is out of: <br>
<input id="DefaultNumber" name="DefaultNumber" type="text" size=3><br>
Type in your guess: <br>
<input id="HisGuess" name="HisGuess" type="text" size=3>
<p>
<input name="StartButton" type="button" value="Guess" onclick="StartGame()">
</p>


 


<script type="text/javascript">


function GenerateNumber()
{
var TheRightGuess = Math.round(Math.random() * (document.getElementById("DefaultNumber").value))+1; //Makes the randomly generated right guess. The "+1" makes it 1-5 instead of 0-4.
}

function StartGame()
{
 var TheRightGuess = Math.round(Math.random() * (document.getElementById("DefaultNumber").value))+1; //Makes the randomly generated right guess. The "+1" makes it 1-5 instead of 0-4.
 var HisGuess = parseInt(document.getElementById("HisGuess").value);//his guess
 var DefaultNumber = parseInt(document.getElementById("DefaultNumber").value);//number that they want to guess in.


//NUMERIC TEST STARTS HERE

if (HisGuess != parseInt(HisGuess) || (DefaultNumber != parseInt(DefaultNumber)))
{
alert("Please enter numbers only.")
}
//NUMERIC TEST ENDS HERE

  if (DefaultNumber <= 0) //Fixed bug:Guessing in zero.
{
alert("You can't guess in zero!?")
}
 else

if (DefaultNumber === 1 && HisGuess === 1  || TheRightGuess == HisGuess && DefaultNumber != 1)//testing if they guessed in 1 and guessed 1.
{

alert("You got the number!")

}
   else

  
  if (HisGuess > DefaultNumber)//if guess is higher then what they guess in.
{


alert("You can only guess below " + DefaultNumber + ".")
}
  else
  if (HisGuess != TheRightGuess && HisGuess <= DefaultNumber && DefaultNumber != 1 || HisGuess == 0)//fixed bug: you can't guess 0.
{

alert("Guess again!")
}
}

</script>

</body>
</html>

Thanks, Fizz

I wish to change the dynamic text in a javascript to that which is in a MySQL database using PHP. this is then used in a flash scroller.

currently i have hard coded the text in the javascript file.

is there a way to have PHP run in the javascript file before it is sent to the endusers?

or another way ?
