JavaScript - Resize Images According To Screen Resolution
Hi All!
I have a web application with an aspanel, users can add images, the program automatically make the thumbnail. when user click on thumbnail they can see a pop up modal page. Images are in different sizes, so what I need to achieve is to get the screen resolution or browser visible area and re-size the image according to this resolution. (users could have different type of computer screen with different resolution), I need a JavaScript or jquery code. Thanks in advance Similar TutorialsHello there I am using the below code to resize images posted on a forum, however when the page is loading it loads the images full size on sreen stretching the page to however wide the largest picture is and only resizes them once every picture has loaded and the page then goes back to normal width. Does anyone know how I could make it so the images only display once they've resized ? Code: <script>
window.onload = resizeimg;
function resizeimg()
{
var theImages = document.getElementsByTagName('img');
for( var i = 0; i < theImages.length; i++ )
{
im = theImages[ i ];
if( im.width > 468 && !/\/(pic1\.jpg|pic2\.jpg)/i.test( im.src ) )
{
im.style.width = '466px';
im.style.border = "1px solid #000000";
im.style.padding = "2px";
im.style.marginBottom = "1px";
im.onclick = function()
{
window.open( this.src, 'fullscale','width='+ this.width +', height='+ this.height +',scrollbars=1,resizable=1').focus();
}
try{ im.style.cursor = 'hand';}catch(e){ im.style.cursor = 'pointer'; }
im.title = 'Click Here To See Image Full Size ';
}
}
}
</script>
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 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" );
}
}

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 there. I'm considering using the script below to detect the screen resolution of the user and then call a specific CSS for that user. The main aim is so that I can design the website at a fixed width for a larger resolution (used by most people), but if the user has a 980px resoltion then they can be catered for as well. Code: <SCRIPT language="JavaScript">
<!--
if ((screen.width>=1024) && (screen.height>=768))
{
window.location="highres.html";
}
else
{
window.location="lowres.html";
}
//-->
</SCRIPT>
I don't want to use liquid layouts as I think it looks messy, and I don't want to design to a width of 960px as I don't like the blank space at the sides on larger resolutions. Is this an acceptable method, or do you think i'll run into problems? Any advice would be great. Cheers. Pat. I 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; ?> I have this script: Code: <SCRIPT language="JavaScript">
<!--
// small
if ((screen.width>=1024) && (screen.width<1280))
{
window.location="0_framside/1_small/849x507.html";
}
// medium
else if ((screen.width>=1280) && (screen.width<1400))
{
window.location="0_framside/2_medium/1105x507.html";
}
// large
else if ((screen.width>=1400) && (screen.width<1600))
{
window.location="0_framside/3_large/1225x639.html";
}
// xlarge
else if ((screen.width>=1600) && (screen.width<1920))
{
window.location="0_framside/4_xlarge/1425x789.html";
}
// manual

See the page in action he http://www.kollalfa.com/temp_LesForMeg/index2.html The problem? On a computer with 1280x1024 resolution, IE detects it to be 1024 (thus sending the user to the wrong page). It works perfectly in all other browsers (that I have tried). Any ideas? Thanks in advance! Dear Forum, I began working on a "best" solution for screen res widths of 1024+ for centralised fixed width pages with potentialy large (or any size) left and right margin graphics and have come up with something I'm very happy with: an outside wrapper set to 100% + overflow hidden (removes the horizontal scrollbar on all screen res) a wrapper inside that set to 1000px with margin auto (allows the central page to be in the middle of, or to fill the page of all screen res - brilliant because originally one main objective was for a left margin not to push the page to the right and out of view on a lower res screen) an inside wrapper inside the centralised one above set to for example, width 1800px and left 400px, allows both margins to be viewable for all screen res larger than the central page (1000px+) ok, so the final hurdle in what for me would be a perfect solution is for any screen res lower than 1000px - currently the horizontal scroll bar is removed - therefore the central page has its right potentialy chopped off.... and so with some research, I've put together the following JavaScript: Code:
<SCRIPT language="JavaScript">
if (screen.width<1000)
{document.getElementById('outsidewrapper').style.cssText='overflow: visible;';}
</SCRIPT>
This is my best effort at JavaScript - I am slowly and steadily learning more. I feel its on the right track, to return the overflow on the outer wrapper would bring the horizontal scroll bar back, but on IE (lower than 1000 res screens) this causes an error and does not work on any browser. If anyone could help with syntax or wisdom how to get this code to work, it'd make for me today a good day, if any of this is difficult to understand without seeing, the site is: http://www.delightwebdesign.co.uk/ many thanks Will Hello, http://www.phoenixdigitalweb.com/Con...urecommercial/ The main image is actually 1087 pixels wide. I want all the photos to appear 1087 pixels wide, but there is some code that is resizing the images. Can someone please take a look for me? Let me know if any code is needed. Thanks!! Hello, I have this short script he Code: function resizeImages() { //Function will be ran onload in the <body> tag
var img = document.images; //Puts all the images in an array
for (var i = 0; i < img.length; i++) { //A loop to execute a set of functions for every image
var parentElement = img[i].parentNode; //Gets parent element of image
var parentWidth = parentElement.width(); //Gets width of parent element (value is an integer without "px")
var imgWidth = img[i].width(); //Gets image width
var parentHeight = parentElement.height(); //Gets height of parent element
var imgHeight = img[i].height();//Gets image height
if (parentWidth < imgWidth){
img[i].width(parentWidth); //Sets width of image to width of parent element
img[i].style.height = "auto"; //Scales height
}
if (parentHeight > imgHeight){
img[i].height(parentHeight); //Sets height of image to height of parent element
img[i].style.width = "auto"; //Scales width
}
alert(parentWidth); //To test if parentNode is working correctly. Should return an integer.
}
}
It's got some JQuery in it (.width() and .height()) to make manipulation of the dimensions easier to manage. Basically, it's supposed to resize all the images on the webpage to the size of their parent elements (divs) without losing aspect ratio. Image overflow will be hidden so that no matter what the aspect ratio of the image and it's container the largest possible area of the image will be exposed. The alert() function I have at the bottom is supposed to run as a test that each loop is working correctly. However, my images don't get resized and I get no alert. I think the loop may be breaking out before it goes through everything. Anyone have ideas? I'm not a Javascript coder. Thank you, Jared So this is my first thread and I am a noob at javascript so please forgive obvious mistakes. I am try to make images float across the screen horizontally. Ideally I would like them to come from both sides and be at different y positions. The problem I am having is that I can only seem to get one to move at a time. Another problem is that when they move off to the right of the screen it expands the viewable size of the site. So here's what I've come up with thus far. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html><head>
<title>Image Mover</title>
<style>
DIV.movable { position:absolute; }
body {
background-color: #0CF;
}
</style>
<script language="javascript">
var x = 5; //Starting Location - left
var y = 5; //Starting Location - top
var dest_x = 1000; //Ending Location - left
var dest_y = 5; //Ending Location - top
var interval = 1; //Move 10px every initialization
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("cloud").style.top = y+'px';
document.getElementById("cloud").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()',100);
}
</script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body background="backgroundgradient.png" onload="moveImage()">
<div id="cloud" class="movable">
<img src="cloud01.png" />
</div>
<script language="javascript">
var x = -100; //Starting Location - left
var y = 5; //Starting Location - top
var dest_x = 1500; //Ending Location - left
var dest_y = 5; //Ending Location - top
var interval = 1; //Move 10px every initialization
function moveImage01() {
//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("plane").style.top = y+'px';
document.getElementById("plane").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('moveImage01()',10);
}
</script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body background="web_layout/backgroundgradient.png" onload="moveImage01()">
<div id="plane" class="movable">
<img src="plane.png" />
</div>
</body>
</html>
Any help is greatly appreciated. Thanks Hi' there Is there anyway to make a custom resize function that resizes one of my div elements on the webpage the same amount of pixels as the browser window gets resized? 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.
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! 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 Hey I have ben writing & understanding this code but I can't make this work, have done my homework..so I have atleast tried http://jsfiddle.net/defencedog/hLZCt/ Hi, I know this is a very bad idea, but I need to do it just to prove a point. I was wondering if it is possible to remove content from a website based on the screen resolution, rather than have to redirect to a new URL. For example: Code: <if height greater than 800px>
Lots of code
<else>
<br/>
</if>
Thank you This is the code my js script. I don't know how to edit the size in this script. My pic is around 300x300. Please teach me thanks a lot. Javascript if ($(".brandbtnch").size()>0) { $(".brandbtnch").click(function(){ var id=$(this).attr("data-id"); var data=$(".data"+id).html(); $(".brandbigpicl").html(data); }); } I just want to resize the pic edit with this script. Thanks is it possible to make a textarea resize with text? so if e.g the text overflows, the text-area is automatically resized so that there's no scrolling? It needs to resize automatically as the user is typing (more or less), he/she shouldn;t click on any buttons to resize it
Hello awesome coders! I am here in need of your help. I have a site with a lot of videos, from different sources, in different sizes, only thing they have in common is <div id="player">. Due do different sources, each video player is different. Some have embed code, some have object, some have iframe, some have both/all. Is it possible to create a script that will: Change the height and width of object, embed, iframe within the div. Is there another way to resolve this issue without changing all video code manually. Hello everyone, My problem consist in that I want to avoid re-loading the whole page, and only re-load the portion of the website that needs to be. Similar to listed below; website Banner (Solid) Menu bar (Solid) Div content (Changeable) The main problem is that no matter what I do, I can't make the innerHTML cover the whole <div> </div> It remains the same very small size, no matter what I put within the div. Far from its full size potential (plenty of space left). Head script Code: PHP Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <html> <head> <script type="text/javascript"> //<![CDATA[ // written by: Coothead function updateObjectIframe(which){ document.getElementById('one').innerHTML = '<'+'object id="foo" name="foo" type="text/html" data="'+which.href+'"><\/object>'; } //]]> </script> <link rel="stylesheet" type="text/css" href="main_stylesheet.css" media="screen, projection" /> </head> Here is the html portion. PHP Code: <div id="one" style="background-color:#C0C0C0;position:relative;height:2000px;width:800px;float:left;"></div> Here is the link placed elswhere on the website (The solid menu bar) PHP Code: <li><a href="http://www.google.com" onclick="updateObjectIframe(this); return false;">Forums</a></li> It's not Google that I want to use, however a PHPBB forum. But I found that the same problem occurs on no matter what I put in this innerhtml, the javascript gets limited to the same little box in the upper left corner of my div. Can't change size, no matter what I tried to do. I'm suspecting it has something to do with CSS, however I spended a whole night (and now day) trying to work this out, I really don't get much further. I realize I should spend a couple of more nights when new to JS, however this kind script I consider like a foundation to a house, it's important before moving on with learning, maybe I'm wrong though. Anyone who can help with this issue? Would be very much appreciated, Thank you! |
