JavaScript - Detect <div> Size And Insert Into Another 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> Similar TutorialsI 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? 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 ". $screen_res; ?> </BODY> </HTML> This all works fine except it doesn't factor in if the user changes their screen resolution for any reason. In my own experience I often change resolutions depending on what I'm doing. I posted the question in there PHP forum http://www.codingforums.com/showthread.php?t=192440 but it looks like I'm needing a pure JS solution. Fou-Lu kindly offered their approach: Quote: Originally Posted by Fou-Lu As for detecting changes, only javascript can do that. Instead of using PHP to check that, use pure javascript and alter you're function to check if its cookies are not existant OR the sizes have changed compared to the cookie, update them. And as mentioned, they will still only take effect after the next page load. Could someone help me with this? I want the end result to be something like http://www.screenresolution.org/ in that if you change your resolution then refresh the page, the screen resolution is updated. I hope I've explained this clearly? Let me know if you need any more information. The next challenge is then getting my PHP functions to work in the following manner: PHP Code: if ($screen_width > 1024){ function('1280'); else { function('1024'); } I have a button (in html) and I want the center of the button to be on the center of the line I'm typing on... I was just putting it inside a span and then using this code to move it down. Code: <span style="position:relative; bottom:-10;"> It worked great! But... once I started allowing my users to change the font sizes the buttons got bigger and they needed to be moved down further... if the font size was +1: Code: <font size="+1"><span style="position:relative; bottom:-10;"> if the font size was +6: Code: <font size="+6"><span style="position:relative; bottom:-27.5;"> So is there a way in javascript to detect the current font size and then adjust the span position based off of that? If I can just get the number of the current font size I can do all the rest of the coding, I just need a way to figure out the current font size and put it in a variable... I was thinking of using something like 1.0em so that it stays the same but then we have a basis of measuring off of but I have no clue.. I'm fairly new to javascript. Thanks! 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?? //Sam QUESTION 1: Hello. I would like to know if this is possible with Javascript, and if yes, if someone can please provide me with the code or point me in the right direction. Let me start of by saying that this is for an eBay listing. I know that they accept basic / limited javascript and if what I am asking is possible, I hope that it can work on eBay listings. I would like to know if it's possible to determine the dimensions of an image with Javascript from an Image url, and to then resize it or not based on the the size of the image. So, let's say this is the URL: www.adomainname.com/image.jpg and let's say that image is 1400 px x 1400 px. I would first like the javascript code to detect that size. I also would like the maximum dimension for any side of the image to be 600 px. If both sides of the image are over 600 px, for both sides to be reduced proportionally to 600 px or lower. If any one side of the image is larger than 600 px, the image is to be resized to 600 px or lower. If both sides are under 600 px, the image is to not be reduced. It would also be nice if it can detect whether the image is portion or landscape based on I guess the larger side, because an image at 600 px in height might be too big, but in width might be o.k. So, in this example (the 1400 px by 1400 px), the image is to be resized to 600 px x 600 px. For an image that's 300 px x 500 px, it should remain as such. For an image that's 400 px x 700 px, it should be resized to 400 / (700 / 600) px by 600 px, which is approximately 343 px x 600 px. I have looked a bit into this and I see things being mentioned about the image being loaded first completely on the screen, or about using server side language like PHP, and so on, but like I said, keep in mind that this is for eBay, and so I am limited. Note: The part that I am most interested in is in being able to detect the size / dimensions of the image. QUESTION 2: On a side note, does anyone know if it's possible to have a Javascript enlarging function for images, in which when one clicks on an image, it is enlarged, but either in a popup window that's smaller than the one behind it, and possibly centered, or by making the background go dark and then bringing up the enlarged image (is the latter done with Javascript; I have seen this effect for a while now and have always wondered.) Hi, Does anyone know if there is a event or something that fires when Javascript finishes executing. When I load a page, the body's onLoad event fires when it has finished loading but there might be some Javascript that is still running (or javascript that is triggered from the onLoad event itself). And this javascript could add to the page's DOM. So is there any way to detect when the page has REALLY finished loading (ignoring the possibility of setTimeout() etc). I need to know this as I am constructing a webpage-scraper and therefore I need to know when the pages have completely loaded. Thanks, I want to - after the page has loaded - detect a text string in the code.. something similar to Code: function afterPageLoadsDetect() {

Simply put -- I want javascript to detect a text string in the source code and return it to me -- AFTER the page is fully loaded. THANKS. Hi there, I basically need script that will detect if the user is using Internet Explorer, and then display a different page to the one that would be loaded for any other browser.
Hi I am trying to trigger an event once the user clicks the browsers back/forward buttons, I have built a system just like facebook where if the user has javascript turned on they get the full feature of the site which includes fast switching for example if someone goes to this page "example.com/index.php" and click a link to contact.php it would change the url to "example.com/index.php#!/contact.php" but what I need to know is if there is any way to change the pages content when the user goes back and forth through the fast switch pages? something like "history.back !== -1" or something like that. If anyone can help please reply, thank you. hi guys, i am using this script (jquery) to resize textareas when a user enters text. it works well. in the management system im writing i would like to also resize all textareas so that all text is visible when forms load i.e. a user loads a form with textareas on and all the text is visible when they read the contents Code: /*

many thanks for any help This is pretty much my first really useful script that I wrote myself. I am trying to load a different index.html page for each different screen size that the browser has. So the page looks best at different resolutions. I am not really able to test it since I haven't finished building all the different resolution index pages yet. I am just wondering if anyone sees any glaring errors in my coding. This is my script: Code: <script src="javascript/stndlibrary.js">
var screendim=getWindowSize();
var screenwidth=screendim[0];
var screenlength=screendim[1];
var screenw=new array(640,800,1024,1280,1400,1600,2048); //Array for standard screen widths
var screenh=new array(480,600,768,1024,1050,1200,1536); //Array for standard screen heights
var indexfilename=new array('vga','svga','xga','sxga','sxgap','uxga','qxga'); //Array for filenames for different pages for each screen size
for (i=0;i<=6;i++);
}
if (screenwidth <= screenw[i]) && (screenlength <= screenh[i]);
{
window.location.replace('http:\\perezcomputer.com\'+indexfilename[i] + 'index.html');
break;
}
}
</script>
The stndlibrary.js file contains the function I wrote to fetch the screen width and height that will be passed back to the script. that function is he Code: function getWindowSize() {
if (window.innerWidth)
theWidth=window.innerWidth;
else if (document.documentElement && document.documentElement.clientWidth)
theWidth=document.documentElement.clientWidth;
else if (document.body)
theWidth=document.body.clientWidth;
if (window.innerHeight)
theHeight=window.innerHeight;
else if (document.documentElement && document.documentElement.clientHeight)
theHeight=document.documentElement.clientHeight;
else if (document.body)
theHeight=document.body.clientHeight;
return [theWidth, theHeight]
}
Please be gentle I am a nOObi... i want to adjust text size according to a page without scrollers. e.g the page should be shown that its scrollers are off and the text on the page spread from top to bottom.
Hi, I'm new here and trying to get some basics via examples. On this page http://www.gilariverwoodworks.com/kitchens.htm I have thumbnails in a table. Immediately below the table is a full sized image of thumb 1. I want to mouseover the thumbs and have the respective full size images swap. The thumbs remain as is. All the thumbs are the same file as the full size image but resized. If moused over, the new image should remain until the next thumb is moused over - ie no autoclose or return to original image. The viewer should be able to move around the page without having the image change til the next mouseover All the images are the same size Can someone offer or direct me to a script that will do this? TIA mr johnson Hi first time poster scratching his head. I am dipping into php to create a user profilepage.php template on a wordpress site. I have managed against all odds to create a user profile that will take info from Code: ?php the_author_meta('occupation'); ?
etc, but my head is spinning trying to create an accordion for a photogallery Code: ?php echo do_shortcode("[photosmash]"); ?
and youtube playlist Code: ?php (the_author_meta('youtube_playlist')); ?
so I want to click on an image "MY VIDEOS" and the youtube playlist drops down, ditto with MY PHOTOS, click on the image and the gallery appears. The page with all the required content showing is http://traditionalpainter.com/andy-crichton I would really appreciate it if someone can point me in the right direction to code that will hide the gallery and video until required. Thanks in advance. Hello, I actually use a counter on a webpage (It works) To do it, I use an inline javascript but I would like to unify the entire page and call that counter directly in the external Javascript that manages the whole site. Here's the actual code... Code: HTML
<body onLoad=gen_hits()>
...
<span id='hits'></span><SCRIPT language="JavaScript" SRC="http://www.mycompany.com/cgi-bin/counterdir/gcount.pl?NUMBER=../../otherdir/counter"></SCRIPT>
...
</body>
EXTERNAL JAVASCRIPT (ini.js)
var hits="HITS ";
function gen_hits() {
document.getElementById("hits").innerHTML=hits;
}
and here a "view" of my request... Code: HTML
<body onLoad=gen_hits()>
...
<span id='hits'></span>
...
</body>
EXTERNAL JAVASCRIPT
var hits="HITS " + <SCRIPT language="JavaScript" SRC="http://www.mycompany.com/cgi-bin/counterdir/gcount.pl?NUMBER=../../otherdir/counter"> </SCRIPT> ;
function gen_hits() {
document.getElementById("hits").innerHTML=hits;
}
Any idea how to modify it ? Thank you very much Gino How can I fixed the size of the page to desired width and length and also make that page fixed to that size so that it cannot resized. And also I want to disable all bars(scrollbars, menubars, address bars etc) for the page. I am using these codes for my projects and these are for commercial purpose. I am also asking for your permission to use these codes for my projects. lookin 4wrd. 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! 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.
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. 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! |
