JavaScript - Centering Content Wider Than Screen

All-

I have a page coded that pulls files from a directory using PHP then sets them up using a Flash type player to stream the video. My problem is that I have to resize the video window for each computer I play it on. They all have different resolutions. I was able to use:

Code:

<script type="text/javascript" src="/jwplayer/swfobject.js"></script>
        <script type="text/javascript">


var x = (+screen.width);
var y = (+screen.height);


if (x == '1920' & y == '1080')
        {
                var xn = 1440;
                var yn = 900;
                document.write(xn);
                document.write(yn);






        }

if (x == '1024' & y == '600')
        {
                var xn = 900;
                var yn = 400;
                document.write(xn);
                document.write(yn);
        }



                swfobject.registerObject("player","9.0.98","/jwplayer/expressInstall.swf");
        </script>

To pull out the current Resolution of the user and pass to a variable the resolution I want the video to be.


Here is where the video code is


Code:

 <object id="player" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="player" width="900" height="400">
                <param name="movie" value="/jwplayer/player.swf" />
                <param name="allowfullscreen" value="true" />

                <param name="allowscriptaccess" value="always" />

                <?
                echo "<param name='flashvars' value='file=../Movies$full_dir.mp4 =../Movies$full_dir.jpg' />";
                ?>
                <object type="application/x-shockwave-flash" data="/jwplayer/player.swf" width="900" height="400">
                        <param name="movie" value="/jwplayer/player.swf" />

                        <param name="allowfullscreen" value="true" />

                        <param name="allowscriptaccess" value="always" />
                        <?
                        echo "<param name='flashvars' value='file=../Movies$full_dir.mp4&image=/Movies$full_dir.jpg' />";
                        ?>
                        <p><a href="http://get.adobe.com/flashplayer">Get Flash</a> to see this player.</p>

                </object>
        </object>

In the video part, where it says Height and Width, I just need to have it take the 2 variables i created depending on the resolution used. Variables xn or yn.

Any ideas? Please Please help! been stumped on this all afternoon!!

Thanks

Hi there

I know this picture_viewr js is a fullscreen slide

Would it be possible to set a screen size (700x500 e.g.) and then set a background color or the part that would be outside this window???


Thx a lot

Hi Guys,

I would like to be able to change my webpage background image according to the screen resolution the user uses so:

if screen resolution is greater than or equals to 1200*600 then background = mybackground.jpg no-repeat

else

background = #000000

THANKS A MILLION!

I am using this javascript code to detect screen size and display an alternate css.

Code:

if (screen.width<1600)
{
 document.write('<link rel="stylesheet" href="<?php echo $path ?>/css/templateadjust.css" type="text/css" />');
}

This works fine in FF and Chrome but doesn't seem to work in IE. Any idea why?

Hi nerds,

We have some problems with some javascript code.
We are creating a new button like the ones known from addthis/sharethis and would like the same behavior as there popups.

We have tried by putting together some different scripts, and the action is about right. We do still have one problem, and that is the position of the popup.
If the button is placed at the right site of a website, it floats out of the screen, making scrollbars. Also it don't have same position behavior in Firefox, IE, Opera ...

The button can be seen he http://www.langthis.com

The code related to this problem should bed this:
Code:

function move_box(an, box)
{
    var cleft = 0;
    var ctop = 0;
    var obj = an;

    while (obj.offsetParent)
    {
        cleft += obj.offsetLeft;
        ctop += obj.offsetTop;
        obj = obj.offsetParent;
    }

	var winW = window.innerWidth ? window.innerWidth : document.documentElement.clientWidth ? document.documentElement.clientWidth : document.body.clientWidth;
	var winH = window.innerHeight ? window.innerHeight : document.documentElement.clientHeight ? document.documentElement.clientHeight : document.body.clientHeight;
	
	if (cleft+box.offsetWidth > winW) {
		cleft = cleft - box.offsetWidth - 30;
		if (cleft < 3)	
			cleft = -3;
	}
	

    box.style.left = cleft + 'px';

    ctop += an.offsetHeight + 8;

    // Handle Internet Explorer body margins,
    // which affect normal document, but not
    // absolute-positioned stuff.
    if (document.body.currentStyle &&
        document.body.currentStyle['marginTop'])
    {
        ctop += parseInt(document.body.currentStyle['marginTop']);
    }

	if (ctop+box.offsetHeight > winH) {
		ctop = ctop - box.offsetHeight - 20;
		if (ctop < 3)
			ctop = -3;
	}

    box.style.top = ctop + 'px';
}

If someone would be interested in rewriting the script, we would credit this in our about page. Else we would be thankful if someone just could help with the existing code.

Best regards

Hi friends,

Thank You

Ok. My first fish is swimming across the screen perfectly fine. He starts from the left side and goes to the right side.
But for the second fish, he is on the right side and he won't swim to the left side.
How do I get him to start swimming? Then he will stop after the interval of 80 reaches like the left one and then start over from the left to the right.
Here is my code:

Code:

		var fish1Position = 0;
		var fish2Position = 0;
		
		horizontal = new Array(80);
		var fillPosition = 10;
		for(var i = 0; i < 80; ++i) {
				horizontal[i] = fillPosition;
				fillPosition += 10;
		}
		
		horizontal2 = new Array(80);
		var fillPosition2 = 10;
		for(var i2 = 80; i2 > 0; i2--) {
			horizontal2[i2] = fillPosition2;
			fillPosition2 = fillPosition2 - 10;
			alert(fillPosition2);
		}
		
		function fish1Swim() {
				document.getElementById("fish1").style.left = horizontal[fish1Position] + "px";
				++fish1Position;
				if (fish1Position == 79)
						fish1Position = 0;
		}
		function fish2Swim() {
			document.getElementById("fish2").style.right = horizontal2[fish2Position] + "px";
			++fish2Position;
			if (fish2Position = 79)
				fish2Position = 0;
		}
		function startSwimming() {
				setInterval("fish1Swim()",100);
				setInterval("fish2Swim()",100);
		}

Hi guys, I'm completely new here and seeking some help on this js:

http://www.javascriptkit.com/script/...ow/index.shtml

i'm building my picture website, an example is this one:

http://www.lucagodina.com/mello/test.htm

do you know how can i have all the thumbnails on the same row, and scrolling? because if i've let's say 100 pictures, the thumbnails will cover the pics itself!

Would also be great to have play-next-previous button...

i know i'm asking a lot! hope someone can help me out!

Good day,

This program is supposed to have a "box" cover the entire screen and then collapse upon opening the page...

I cannot find what is wrong, other than the obvious error that there is no object or it is null, but this is the example the book gave...

Anyone care to give me a point in the right direction

Thanks, in advance.

Hey guys, I was trying to make a Javascript game that moves an image across the screen randomly. Instead of executing properly, it just shows the image's starting point, and stops. No movement. Is there anyway I could fix this? Thanks, Fizz.



Code:

<html>
<head>
<title>Image Mover</title>

<style>
DIV.movable { position:absolute; }
</style>
</head>
<script language="javascript">


function Start() {

var x = 5; //Starting Location - left
var y = 5; //Starting Location - top
var dest_x = Math.floor(Math.random()*650);  //Ending Location - left
var dest_y = 500;   //Ending Location - top
var interval = 10; //Move 10px every initialization
	moveImage();

}

function NewDest() {

var x = 5; //Starting Location - left
var y = 5; //Starting Location - top
var dest_x = Math.floor(Math.random()*650);  //Ending Location - left
var dest_y = 500;   //Ending Location - top
var interval = 10; //Move 10px every initialization
	moveImage();
}


function moveImage() {
	//Keep on moving the image till the target is achieved
	if(x < dest_x) x = x + interval; 
	if(y < dest_y) y = y + interval;
	
	//Move the image to the new location
	document.getElementById("ufo").style.top  = y+'px';
	document.getElementById("ufo").style.left = x+'px';

	if ((x+interval < dest_x) && (y+interval < dest_y)) {
		//Keep on calling this function every 100 microsecond 
		//	till the target location is reached
		window.setTimeout('moveImage()',30);
	
	if (x == dest_x) && (y == dest_y) {
		NewDest();
		}
		
			





}
}
</script>
<body onload="Start()">
<div id="ufo" class="movable">
<img src="Mouse.jpg" alt="mouse" WIDTH = 30/>
</div>

</body>
</html>

I have been using wz_tooltip and have a big tooltip that needs to be opened at the top of the screen, not by the cursor in order to be read. What do I add to the script to do this?
Thanks, Wina

Hi all,

I'm new to javascript and im trying to teach myself how to use it, however, ive come accross a problem. I'm using this code embeded in a HTML page for rollover images:

Code:

<script language="JavaScript" type="text/javascript">
				<!--
					if (document.images) {

						homebuttonup       = new Image();
 						homebuttonup.src   = "./Images/nav/home2.png" ;
  						homebuttondown     = new Image() ;
  						homebuttondown.src = "./Images/nav/home2.png" ;
	
						newsbuttonup       = new Image();
 						newsbuttonup.src   = "./Images/nav/news.png" ;
  						newsbuttondown     = new Image() ;
  						newsbuttondown.src = "./Images/nav/news2.png" ;
	
						gallerybuttonup       = new Image();
 						gallerybuttonup.src   = "./Images/nav/gallery.png" ;
  						gallerybuttondown     = new Image() ;
  						gallerybuttondown.src = "./Images/nav/gallery2.png" ;
						
						}

						function buttondown( buttonname )
						{
    						if (document.images) {
    					  document[ buttonname ].src = eval( buttonname + "down.src" );
    						}
							}
						function buttonup ( buttonname )
							{
  						  if (document.images) {
    					  document[ buttonname ].src = eval( buttonname + "up.src" );
    					}
					}
				// -->
			</script>
           
<a href="index.html?cmd=welcome" onmouseover="buttondown('homebutton')"onmouseout="buttonup('homebutton')">
<img src="./Images/nav/home2.png" name="homebutton" border="0" /></a>
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

This works completly fine in 1280 x 800 but goes mental when you hover over it in 1024 x 768 screen resolution. Can anyone help please, it would be greatly appreciated!

Hi all,

I'm trying to detect the screen resolution of the client's computer.
I've been using the following example:

PHP Code:
<HTML>
<TITLE>screen resolution</TITLE>
<HEAD>
</HEAD>
<BODY>

<?php
if(isset($_COOKIE["users_resolution"]))
$screen_res = $_COOKIE["users_resolution"];
else //means cookie is not found set it using Javascript
{
?>
<script language="javascript">
<!--
writeCookie();

function writeCookie()
{
var today = new Date();
var the_date = new Date("December 31, 2023");
var the_cookie_date = the_date.toGMTString();
var the_cookie = "users_resolution="+ screen.width +"x"+ screen.height;
var the_cookie = the_cookie + ";expires=" + the_cookie_date;
document.cookie=the_cookie

location = 'get_resolution.php';
}
//-->
</script>
<?php
}
?>


<?php
echo "Your screen resolution is set at ". $screen_res;
?>
</BODY>
</HTML>

This all works fine except it doesn't factor in if the user changes their screen resolution for any reason. In my own experience I often change resolutions depending on what I'm doing.

I posted the question in there PHP forum http://www.codingforums.com/showthread.php?t=192440 but it looks like I'm needing a pure JS solution.

Fou-Lu kindly offered their approach:

And as mentioned, they will still only take effect after the next page load.

Could someone help me with this?
I want the end result to be something like http://www.screenresolution.org/
in that if you change your resolution then refresh the page, the screen resolution is updated.

I hope I've explained this clearly? Let me know if you need any more information.

The next challenge is then getting my PHP functions to work in the following manner:
PHP Code:
if ($screen_width > 1024){
   function('1280');
else {
  function('1024');
}
