JavaScript - Detect Resolution?
im totally new to javascript and i would like to know how i can make my internet page detect the resolution of someone's computer and on base of that use different 'html pages' so that the background fits etc.
Similar TutorialsI have set javasscript code to detect and store into variable screen resolution. How to store this javascript into variable PHP? PHP Code: <script type="text/javascript"> var ScreenWidth=screen.width; var ScreenHeight=screen.height; var ScreenResolution=ScreenWidth+"x"+ScreenHeight; document.write("<span style=\"color:red;text-transform: capitalize;\">your current screen resolution is " + ScreenResolution + "</span>"); --></script> } </script> <?PHP $screen=str_replace("#","",$resolution); echo "screen width is:".$screen; ?> hey all is there a code where I can detect if the browser is IE6 or IE7 and send them to another webpage? my current design is not compatible with IE6 or 7 and i want to make a new page that's compatible. thanks! I am attempting to make an page on my website where visitors can set my website as their homepage. I am trying to make my website read which browser my visitors are using and then redirects them to the page for the right browser where I can tell them how they can set my website as their homepage. Basically I need exactly the same thing as THIS. Could you explain to me in plain English how I can realize this. This is what I know have: Code: <table width="759" border="0" align="center" cellpadding="0" cellspacing="0" >
<tr align="center">
<td width="378" height="28" align="right">Selecteer jouw browser </td>
<td width="16"></td>
<td width="365" align="left"><form id="browserSelection" name="browserSelection" action="customizeBrowser" method="GET"><select name="browser" size="1" id="browser" onchange="document.browserSelection.submit();"><option value="ff" selected>Firefox</option><option value="ie">Internet Explorer</option><option value="chrome">Chrome</option><option value="opera">Opera</option><option value="safari">Safari</option></select></form></td>
</tr>

________________________________________ Please tell me if I make any English mistakes in my posts. I am trying to write as perfectly possible. I really want to learn a way determine whether custom fonts via @font-face got downloaded by the client machine and then set styles differently depending on whether they got the fonts or not. To start I could run a fonts-inactive.css file to setup the styles to look nice without custom-fonts (this is the base style which should look fine without any JS, flash, custom fonts, etc.). Then run a JS that will run the font-face-rules.css (which attempts to load the fonts via @font-face css rules) - this way if JS isn't active then no fonts will be loaded and the document will default to its fonts-inactive.css. If the JS does run then font-face-rules.css will try to send the fonts. So the JS needs to somehow determine whether the fonts worked or not. If the fonts worked then the JS would run the fonts-active.css which would alter some style rules to make the page look better with the custom fonts (since we know they got the fonts we can tweak the page a little to look better with them). If the fonts didn't work then the JS needs to not run the fonts-active.css and instead just exit out leaving the document with its original, unaltered rules from fonts-inactive.css. (since we know they didn't get the fonts we leave them with the baseline stylesheet which optimizes the appearance for default fonts). Sadly I don't know the first thing about Javascript so I am hoping that you guys might be able to help me come up with something that works. Cheers, line I have been searching for a way to accomplish a unique task for a while. Here's the situation: We have several users who are in locations where YouTube is blocked for various reasons. On our homepage we would like to embed a YouTube video except for when YouTube is blocked and then embed an alternative video that is hosted off one of our servers. Is there a way to use JavaScript to detect whether or not YouTube is available and then put in the correct video? Thanks in advance! 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! i have a problem. i want to check that whether an element with a specific id exist on page or not. example Code:
<script type="text/javascript">
function bgcolo()
{
if(document.getElementById("jj") == null)
{
return red;
}
else
{
return green;
}
}
</script>
</head>
<body>
<table width="100%" border="1">
<tr>
<td id="oo" bgcolor="return bgcolo();">bvbv</td>
</tr>
</table>
<div id="jj">fggftrytyyyyyyyyy</div>
</body><
Hi once again! Is it possible to detect was the mouse on the move or not in the moment when button is released ? Hi.. Anyone can help me to reslove tis.. How to detect iTune plugin in IE Browser...Am using navigator.plugins[] array..its working in firefox,chrome but i need for IE browser..pls help on tis very urgent.. Hi, I am currently detecting for Shockwave within IE by doing the following: Code: var isInstalled = false;
if (window.ActiveXObject) {
var control = null;
try {
control = new ActiveXObject('SWCtl.SWCtl');
} catch (e) {
return;
}
if (control) {
isInstalled = true;
}
}
This works as expected and if it fails to detect Shockwave I tell the user to install Shockwave. The problem comes when AcitveX is disabled as it still returns the same message that it's not installed. I would prefer to be able to include an extra step to detect if ActiveX is disabled, in which case I can tell the user to enable it rather than giving them false advice. My only idea would be to detect for an ActiveX Object that every IE user should have installed. Any ideas on what that ActiveX Object could be or any ideas on how I could tackle this problem are greatly appreciated. Thanks Hi all, The code I am working on uses the idea of detecting mime type support, to see if the add-on is there. Then if the mime type is not supported, it assumes, the add-on is not installed. (No other add-ons have this mime type.) However, there is a problem, if someone disables the add-on, the there is no mime type handler in navigator.mimeTypes['the/MimeType']. Is there some way to detect if an add-on is installed, and also if the add-on is enabled? Thanks, Grae Hi all,i'm wondering how to detect select option changes.For example i want the data in database changed when i click on update button and if there are changes on the select option side.If the values on the select option are not changed,i can't update the data..Is there a way to achieve it?Thanks a lot...
I am struggling to find a solution that enables me to have a div that is a certain percentage height of the window and then when the user is using a different resolution, it remains at that percentage of the screen height - not going off of the bottom as I have a fixed percentage no scroll full background image. I have sorted it for width but can't get it to work for height. any ideas? lol Bee x 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>
<a href="about.html?cmd=welcome" onmouseover="buttondown('newsbutton')"onmouseout="buttonup('newsbutton')">
<img src="./Images/nav/news.png" name="newsbutton" border="0" /></a>
<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've been trying to get this script working to change a couple attributes in the CSS but it hasn't been working. It's supposed to change the left and right margins of the #content tag if the resolution is greater that 1024x768. The text doesn't seem to want to stay in the center. Heres the code: Code: <!--
if (screen.width > 1024)
{
ChangeCSS('#content','marginLeft','28%');
ChangeCSS('#content','marginRight','29%');
}
//-->
Heres the CSS: Code: #content {
margin-bottom:0;
margin-top:0;
margin-left:24%;
margin-right:27%;
position: absolute;
width: 38em;
}
The CSS code is all inline because this is a tumblr and I don't have a place to host style sheets. Can anyone tell me whats wrong? Thanks! In my application I want user to take an "Exit Survey"(Independent website) when he is leaving the application. As name explains, It should happen only when user closes current browser tab or browser window. Its possible using JavaScript OnUnload event. But the problem is that this event occurs on 1. close of browser tab 2. close of browser window 3. click of any internal page link(i.e anchors and form buttons) 4. click of browser's Refresh button 5. click of browser's Back/Forward button I have handled first 3 cases but not able to detect Refresh and Back/Forward button click. Has anybody of you implemented such functionality?? Thanks in advance!!! Sorry fellas, I am a complete noob I am trying to detect if a users browser is Internet Explore Version 9 the subsequently redirect that browser to a new page that is IE 9 specific in my directory. My code does NOT seem to be working. Could any of you kind folks take a look and see the mistake? <script language="JavaScript" type="text/JavaScript"> if(navigator.appName == "Microsoft Internet Explorer"&& navigator.appVersion >=8) { window.location = "SeansWebsite_2012_IE9.html" } <!-- the page that i am starting on is "SeansWebsite_2012.html"--> </script> I want to have a browser language detection for 2 languages for Explorer and Firefox and struggle a little to make it work. I don't know really much about JavaScript so I guess I did some grave errors. It works for one language though, but for that I don't really detection. I am not sure if that's wrong, but I try to look for the 'en-' in the language not to deal separately with en-US, en-AU, en-UK etc. PHP Code: <script type="text/javascript"> var str=navigator.language; x = (str.search(/en-/i)); if ( !(x=='-1') ) { document.write("English Mozilla"); } var expl=navigator.browserLanguage; ex = (expl.search(/en-/i)); if ( !(ex=='-1') ) { document.write("Englisch1 Explorer"); } var dm=navigator.language; d1 = (dm.search(/de-/i)); if ( !(d1=='-1') ) { document.write("German Mozilla"); } var dex=navigator.browserLanguage; dexpl = (dex.search(/de-/i)); if ( !(dexpl=='-1') ) { document.write("German Explorer"); } </script> i need script will detect connection speed and redirect to a page:
I have a goal in mind, and that is to get the width & height of a <DIV> tag in one document and insert them into another document...all on the same domain. It sounds like a simple task, but in case more detail is needed, let me explain: I have a page called 'demo.html' which launches a page called 'gallery/archive_iframe.html' via Shadowbox as an iFrame. The problem is that 'gallery/archive_iframe.html' slightly differs in dimension on every browser and screen resolution. I want to have the iFrame's size detected every time it launches so Shadowbox can get solid dimensions to display it without scrollbars. You can see the current (fixed size) example at: http://www.mikegermond.com/demo.html Click on the 'Video Archive' image. Here is the code I would like to insert the dimensions in to: Code: <A HREF="/gallery/archive_iframe.html" rel="shadowbox;width= ??? ;height= ??? " class="imgLink" title="Video Archive"><img src="gallery/videoarchive_thm.jpg" alt="Launch Video Archive (popup window)" width="260" height="162" border="0" /></A> |
