JavaScript - Screen Size Not Working In Ie

Hi All,
I am using jFlow slider for my website and in the head there is that function
<script type="text/javascript">
$(document).ready(function(){
$("#myController").jFlow({
slides: "#slides",
controller: ".jFlowControl", // must be class, use . sign
slideWrapper : "#jFlowSlide", // must be id, use # sign
selectedWrapper: "jFlowSelected", // just pure text, no sign
auto: true, //auto change slide, default true
width: "706px",
height: "420px",
duration: 500,
prev: ".jFlowPrev", // must be class, use . sign
next: ".jFlowNext" // must be class, use . sign
});
});
</script>

What i want to do is detect the browser window (max width 1024 ) and change the width and height attribute of this function...something like this :

<SCRIPT language="JavaScript">
<!--
if ((screen.width<=1024) && (screen.height<=768))
{
$(document).ready(function(){
$("#myController").jFlow({
slides: "#slides",
controller: ".jFlowControl", // must be class, use . sign
slideWrapper : "#jFlowSlide", // must be id, use # sign
selectedWrapper: "jFlowSelected", // just pure text, no sign
auto: true, //auto change slide, default true
width: "706px",
height: "420px",
duration: 500,
prev: ".jFlowPrev", // must be class, use . sign
next: ".jFlowNext" // must be class, use . sign
});
});
}
else
{
$(document).ready(function(){
$("#myController").jFlow({
slides: "#slides",
controller: ".jFlowControl", // must be class, use . sign
slideWrapper : "#jFlowSlide", // must be id, use # sign
selectedWrapper: "jFlowSelected", // just pure text, no sign
auto: true, //auto change slide, default true
width: "706px",
height: "420px",
duration: 500,
prev: ".jFlowPrev", // must be class, use . sign
next: ".jFlowNext" // must be class, use . sign
});
});
}
//-->
</SCRIPT>


But can't get this to work...any help please??

Hi developers

Needing some help.

My javascript/css drop down menu is not working on the ipad or other touch screen devices. It works fine on laptops & desktops which use a mouse.

I've discovered that this is because touchscreen devices like the Ipad do not recognise the onmouseover/onmouseout event handler that my script relies on. Is there any way I can modify my script so that it is compatiable both with traditional devices and touchscreen devices?

The code I am using is:
<script type="text/javascript"><!--
var timeout = 500;
var closetimer = 0;
var ddmenuitem = 0;

// open hidden layer
function mopen(id)
{
// cancel close timer
mcancelclosetime();

// close old layer
if(ddmenuitem) ddmenuitem.style.visibility = 'hidden';

// get new layer and show it
ddmenuitem = document.getElementById(id);
ddmenuitem.style.visibility = 'visible';

}
// close showed layer
function mclose()
{
if(ddmenuitem) ddmenuitem.style.visibility = 'hidden';
}

// go close timer
function mclosetime()
{
closetimer = window.setTimeout(mclose, timeout);
}

// cancel close timer
function mcancelclosetime()
{
if(closetimer)
{
window.clearTimeout(closetimer);
closetimer = null;
}
}

// close layer when click-out
document.onclick = mclose;

//--></script>

Which drives the following html:

<ul id="links">

<li><a href="whats_new/whats_new.html">what's new</a></li>

<li><a href="#"

onmouseover="mopen('m1')"

onmouseout="mclosetime()">clothing</a>

<div id="m1"

onmouseover="mcancelclosetime()"

onmouseout="mclosetime()">

<a href="clothing/clothing_page1.html">clothing</a>

</div>

</li>

<li><a href="#"

onmouseover="mopen('m2')"

onmouseout="mclosetime()">accessories</a>

<div id="m2"

onmouseover="mcancelclosetime()"

onmouseout="mclosetime()">

<a href="bags/bags_page1.html">bags</a>

<a href="jewellery/jewellery_page1.html">jewellery</a>

</div>

</li>
</ul>

Any suggestions would be much appreciated.

Thank you.

I have an iframe that is a specific height and width. I want to detect whenever the the iframe is no longer exactly the height i set it to. If a user has CSS turned off for example the iframe will be in default height and width. I want to detect that.

This is how you'd normally do it but this only returns the original size (try with 'no style' in Firefox):

Code:

function getSize()
{
alert('height is now '+document.getElementById("Iframemain").height)
alert('height is now '+document.getElementById("Iframemain").width)
}

Is it possible?

I want to have a screen (50% transparent white) pop up over an image on rollover with a button that, when pushed, will swap the image with a different one. Anyone know the easiest way to do this. The image is in a scrolling bunch of images similar to this: http://kellyperso.com

I use a program that produce a graphic (imagine a sinusoid, more or less).
There is no opportunity to obtain from the program an output of the coordinates of the points of this curve.
I desperately tried a way to achieve this, for example using a program that transform a normal raster image in a vector, and after read the vector, but all this is not precise nor accurate.
I wonder if there is a way to obtain this result.
Bye

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
Defyer!

Hi

I have the code below which geocodes a postcode and returns a lat a long value. Its standard code from Google maps. I just want to print these values to a screen. I tried document.write(value) but this produces nothing. Any help would be greatly appreciated.

Code:

<script type="text/javascript">
	var localSearch = new GlocalSearch();
	function usePointFromPostcode(postcode)
	{
		localSearch.setSearchCompleteCallback(null, 
			function()
			{
				if (localSearch.results[0])
				{		
					var resultLat = localSearch.results[0].lat;
					var resultLng = localSearch.results[0].lng;
				}
				

				document.write(resultLat+resultLng); 

				
				//alert("Latitude: " + resultLat + "\nLongitude: " + resultLng + " q");				
			});	
		localSearch.execute(postcode + ", UK");
	}
</script>

TIA Stew

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.

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;  
<a href="about.html?cmd=welcome" onmouseover="buttondown('newsbutton')"onmouseout="buttonup('newsbutton')">
<img src="./Images/nav/news.png" name="newsbutton" border="0" /></a>
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
<a href="services.html?cmd=welcome" onmouseover="buttondown('gallerybutton')"onmouseout="buttonup('gallerybutton')">
<img src="./Images/nav/gallery.png" name="gallerybutton" border="0" /></a>

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!

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>

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!

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
