JavaScript - Get Code To Execute Inline Instead Of Jumping To Top Of Page?

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?

FF, Safari, Opera all execute this javascript code to refresh the page properly, but in IE version 8.0.6001.18904 the page doesn't seem to refresh on click of orange_refresh button. I have checked out a different version of IE8, don't recall exact version, but it did seem to work fine in that one, whatever version it was probably the latest now that I think of it. Check out code below any sug.'s could be helpful, though its probably a bug..
Code:

<a href="javascript:document.location.reload();"
onmouseover="window.status='Refresh'; return true"
onmouseout="window.status='Page Refreshed'"><img src="image/orange_refresh.png" 
width="30" height="30" border="0" /></a>

First off; i was in two minds if this belonged in the .php forum or the javascript forum; i apologize if i chose the wrong one.

I have this .php code:
PHP Code:
<?php 
        $query = "SELECT mail_id FROM ".TBL_MAIL." WHERE UserTo = '$session->username' and status = 'unread'";
        $numUnreadMail = $database->query($query) or die(mysql_error());
        $numUnreadMail = mysql_num_rows($numUnreadMail);

        if($numUnreadMail == 0){ echo '<img src="../images/global/mail_imgs/inbox_0.png" width="22" height="15" />';}
        if($numUnreadMail == 1){ echo '<img src="../images/global/mail_imgs/inbox_1.png" width="22" height="15" />';}
        if($numUnreadMail == 2){ echo '<img src="../images/global/mail_imgs/inbox_2.png" width="22" height="15" />';}
        if($numUnreadMail == 3){ echo '<img src="../images/global/mail_imgs/inbox_3.png" width="22" height="15" />';}

which displays in this navigation:
<li><a href="#"
onmouseover="mopen('m1')"
onmouseout="mclosetime()"
class="link_image">
<?php
include_once('../include/mailicon_codes.php');
?>
</a>

I wondered how or if it is even possible to use javascript to execute the first .php code so that the user would know if he/she had a new message without refreshing the page?

Any help is greatly appreciated as i suck at .js

cheers, Callum

Ok guys if you look at this page www.runningprofiles.com/members/shout/view.php my code works great....

But when i add it to the rest of the script the code wont work shows he

edit:: got it to work setting inBooth to false in the function where I clear the menu, but then it's refreshing to div so often while you're standing in the booth (30 frames/sec, it's a game) that nothing happens when you click the buttons to buy/sell unless you click really really fast....

anyone know a good way to check whether something is true, then toggle an innerHTML div, then once the value becomes false, toggle the innerHTML div to empty....??simply??


But if I reverse the order the opposite works but then the other doesn't......

Code:

if (condition==true ) {
generateSale();
inBooth=true;
smithShop();
} else {inBooth=false;clearSale();}
  
 
//IS PLAYER IN VENDOR BOOTH?
if (condition2==true ) {
generateSale();
inBooth=true;
vendorShop();
} else {inBooth=false;clearSale();}

Only the "generateSale()" from the second one executes. If I switch the if blocks, the second one with "generateSale()" executes.

If I change "clearSale();" to a "setTimeout=('clearSale()',1000)" then both execute "generateSale()" but the div it affects flickers repeatedly as it's cleared/remade.

generateSale() changes the innerHTML of a div, clearSale() just overwrites the innerHTML with ' '

Code:

var sales2;

function clearSale() {
	sales2=document.getElementById('sales2');
	sales2.innerHTML='';
	}

function generateSale(){ 
	 sales2=document.getElementById('sales2');
	sales2.innerHTML=
	'Buy/Sell:  '+'   Gold coins: '+playerInventory[lootArray[7]]+'<br>'
	+'        Consumables:<br>'
	
	+'You have: '+playerItems[itemArray[4]] +' arrows<br>'
	+'<input type="button" value="Buy" onclick="buyIt(0);">'+'10 for 50gp<br>'	
	+'<input type="button" value="Sell" onclick="sellIt(0);">'+'10 for 25gp<br>'
}

Any ideas? Basically when my character enters the range of an image of a building I have a menu pop up saying you're in a vendor booth.

I want it to run generateSale() which changes a div on the screen to list a bunch of stuff you can buy/sell. When your character is no longer standing in range, I want it to clear that information, so you have to be standing within range in order to trade items.

Currently I can make it generates the sale menu, but it doesn't clear it when you leave the range. I've tried all kinds of "toggle" variables to set whether you're in range or not, but only the second block fires, not the first and I cannot figure out why...

Any ideas? The code all works fine it just won't clear for all the different buildings, only one....

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

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 (:

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

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?

For example, how can I write "Hello!" on the page every Friday at 8:40?

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

Hi, I'm doing something wrong, I want my script to execute when the browser window opens, can someone please help me?

Code:

<p><iframe id="myFrame" style="display: none;" width="500" height="300"></iframe>
<script type="text/javascript">// <![CDATA[
    window.onload=openpdf();
    type="text/javascript">// <![CDATA[
        function openPdf()
        {
            var omyFrame = document.getElementById("myFrame");
            omyFrame.style.display="block";
            omyFrame.src = "myFile.pdf";
        }
        // ]]></script>

All,
I have a script that runs some jQuery and appends it to a <div>. I only want this script executed if a user is using IE7 or higher since jQuery doesn't work with IE6. How can I do that? Also, if they aren't using IE7 or higher I don't wnat to display the <div> that the results go into. How would I go about doing this?

Thanks!

Hi,

I'd like to create a textarea and a division so that whatever embed code you put in the textarea it gets executed on the division in real-time.

Your kind help is greatly appreciated!
JavaScript newbie

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.
