JavaScript - Simple Javascript Url Redirect Based On Aspect Ratio Of Screen
This is what I tried but alas, it does not work por que no?
This is located on my main index file which if the result of z is greater than 1, I would have the user stay at this page as opposed to redirecting to the portrait design. I have optimized the website for mobile use so there is a reason of having two different pages, the wide screen has extra tools / other stuff that isn't shown on the portrait not because of size/responsive design but becasue I want it to be this way. Anyway... "What's the situation captain?" This is located above my <style> tag Code: <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script language="JavaScript" type="text/javascript">
<script>
function redirect() {
var x = screen.width;
var y = screen.height;
var z = x/y;
if (z<1) {
window.location.replace("alternate destination");
};
else ( ){
// stay here
};
};
</script>

Join Date Feb 2009 Posts 28,311 Thanks 82 Thanked 4,754 Times in 4,716 Posts You have extra semicolons in there. In general, don't put a semicolon directly after a right brace }; There are a couple of exceptions, but they don't apply here. What's the point in having the else?? Similar Tutorialshello, ive been wondering about this possibility for a while. i havent been able to find an answer to it using google, but im not very knowledgable about javascript in the first place. what id like to do is make a webpage that has one frame (or div if its necessary) that resizes based on a percentage of the size of the user's window upon loading, but always keeps the same aspect ratio. to get more specific: i want that second frame (or div) to have a locked 4:3 ratio. can this be done? Im trying to get this script working on this game on Kongregate Im experimenting on this I took some script which resizes the whole game to its maximizations and I thought it needs to keep aspect ratio anyway I tried to modify all I can but all I get are gaps and game gets aligned to left some reason I couldnt find out I based it on this http://userscripts.org/scripts/show/34214 so can you tell me what I am doing wrong to get those gaps and what I need to do to make game not get aligned to left Im working like zomg I have a simple javascript for validating the radio buttons. But for what ever reason window.location does not redirect. this is my code: <SCRIPT LANGUAGE="JavaScript"> function checkRadio (frmName, rbGroupName) { var radios = document[frmName].elements[rbGroupName]; for (var i=0; i <radios.length; i++) { if (radios[i].checked) { return true; } } return false; } function valFrm() { if ( checkRadio("frm1","radio1")==true && checkRadio("frm1","radio2")==true) window.location="price.jsp"; else alert("You didnt select any price"); } </script> when i replace an alert with the redirect line it works fine. any help would be appreciated. Can anyone help me out with a script that can redirect based on IP address? I want all of my computers on my LAN, 192.168.1.1-255 to be redirected to a specific page. IE When I type in test.homeip.com it goes to my web server and reads the index.html file. If the IP is in the 192.168.1.0 range it will redirect to 192.168.1.10:80 and if its any other IP it will send it to 192.168.1.11:80 Thanks! Hi guys. I am kind of new to javascript, and was hoping that someone here could help out on a problem I have been having. What I am trying to do is to make a page which will redirect to three diffrent sites, based on date. I want it to change to diffrent sites during the time before summer to summer, the time before xmas till xmas and from before easter till easter. A bit more spesific this would be: From 29. march --> 22. july (summer) From 22. august --> 24. december (xmas) From 3. january --> 22. march (easter) Could you help me out? I have tried lots of diffrent ways to do this with javascripts if...else statements, but I havent yet found a way to make it work properly. Really thankful for answers! Hello all. I have created a 2 frame site where I want the top frame (header) to redirect the other frame (main) to a different page depending on the date, time, and second. For example, on 12 FEB at 07:00:00, I would like the header frame to redirect the main frames page to EmmasBday.html; in which I would be alerted of my little sisters Birthday. This is for personal use and isn't going to be hosted online so I will just use JavaScript, it's basically a simple system to remind me of crucial events at certain times and dates so I don't forget them. The same events will apply every year, so there is no need to programme in specific years although having the option could prove useful. I am aware of other alternatives to achieve this, but would very much like to work with JavaScript; as I can expand it. As I state, this is for personal use and therefore won't be hosting it; I will use JavaScript throughout and cannot use anything else like PHP, Perl, etc. I am aware JavaScript takes the time & date from the computer hosting it (unlike PHP), which is fine. So, for example; at 14:30:00 I will be informed to get dinner; and at 15:00:45 I'll be informed to study. The knowledge you guys have presented so far is phenomenal, and I couldn't think of anybody better to ask for assistance. Anyway, I hope you can resolve my problem and I'm looking forward to a response! Thanks for your concern, you brain Gods you! AHa. I am having some trouble trying to adapt some code to create a better user experience. I use a Rapid E-learning Dev Tool called Udutu. Its limited in some functionality but I'm hoping to find a workaround. As with a lot of e-learning, user activity including their assessment score is passed to the LMS via a Scorm connection. I need to get that score and then based on the percentage (i.e <= 79) re-direct the user automatically to a page. To get the score within Udutu is as follows: Code: <p>Your score is: <span id=theScore></span>
<script>try{var theScoreEl = document.getElementById('theScore');theScoreEl.innerHTML= Math.round(UDUTU_API.generateScore());}catch(ex){}</script>
% </p>
This bit works fine but now I need to include a if statement to look at the value that it produces and redirect the user accordingly. I've tried to do this but I keep breaking the above code. Any help would really be appreciated Hello, Im looking for a script where i can have people come to my websites index page, watch a short video and learn about what my site is about, then click a button called "always skip to "my website here" " so once they click that button, they will always be directed to my main website when they return. I belive it will need to be done with cookies aswell? Thanks Chris, I have a page up with an iframe that's approximately 300px by 405px. When I load up the site in FF and IE, it frames just fine. However, in Chrome and Opera the iframe is shifted upwards and is off-frame. I've tried looking for a solution to center the iframe correctly. Someone said to make a php code that loads 2 different iframes depending on browser (1 iframe for IE/FF and another frame for OP/CH). I have no knowledge of php coding, so I couldn't get it to work. So now, I think I'm limited to redirecting users based on browser type. If the user is using FF or IE, I'll redirect them to my original page. If they're using some other browser, I'll redirect them to a different page without the iframe. I've tried to set up a redirector, but it has trouble distinguishing between FF and Chrome. It treats them exactly the same. Does anyone have any advice on what to do? I've done tons of searching for what seems to be such a small problem. Someone please enlighten me. Hi, Please i am not getting clear understanding of a javascript code to redirect user to a different web page based on the day of the week. Please i have search for many script and not getting clear understanding from their code.I have also try several code myself but nothing good has come from it. Please can someone help me and write a descriptive code for me to understand better.I really plead you and your to help me...but i belief the Lord God will bless you for your time helping me. looking forward to here from you. Thank you. Clement Osei I am having trouble writing this javascript for my work, normally I would do this in ASP or PHP, but the environment I am working with will only allow javascript for dynamic function. The form has two different select boxes and based on your options selected for select box #1 and select box #2, the hidden input field "redirect" (which is currently empty) would then populate dynamically with the URL associated with that combination mentioned below. The hidden redirect input field (now containing dyanmically generated data) would then pass the new value via HTTP_POST to .net script that will handle the redirect processing step fed to it. Here are the mappings: If selections = Elementary & Vocabulary = http://www.widget.com/content/elem-vocab If selections = Elementary & Writing = http://www.widget.com/content/elem-writing If selections = Elementary & ELD = http://www.widget.com/content/elem-eld If selections = Middle School & Vocabulary = http://www.widget.com/content/midscl-vocab If selections = Middle School & Writing = http://www.widget.com/content/midscl-writing If selections = Middle School & ELD = http://www.widget.com/content/midscl-eld If selections = High School & Vocabulary = http://www.widget.com/content/hiscl-vocab If selections = High School & Writing = http://www.widget.com/content/hiscl-writing If selections = High School & ELD = http://www.widget.com/content/hiscl-eld Here's a snippet of a different method that I tried, but it did not work. I think the above mentioned method would probably be best. Code: <script language="javascript" type="text/javascript">
<!--
function build() {
document.fillgaps.redirect.value = "http://www.widget.com/content/" + document.fillgaps.grade.value + "-" + document.fillgaps.solution.value ;
//print example: http://www.widget.com/content/ELM-VOC
return true;
}
-->
</script>
<form name="fillgaps" action="http://www.widget.com/submit.aspx" method="post" onSubmit="return build();">
<input type="hidden" name="redirect" value="">
<table class="elqFormTable" border="0" cellspacing="2" cellpadding="2">
<tr>
<td valign="top">Grade:</td>
<td>
<select name="grade">
<option value="ELM">Elementary</option>
<option value="MID">Middle School</option>
<option value="HIG">High School</option>
</select>
</td>
</tr>
<tr >
<td valign="top">Solution:</td>

<select name="solution">
<option value="VOC">Vocabulary</option>
<option value="WRI">Writing</option>
<option value="ELD">ELD</option>

I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Here's my firstly: PHP Code: <?php echo "<script language=\"javascript\" type=\"text/javascript\"> var g_iCount = new Number(); // CHANGE THE COUNTDOWN NUMBER HERE - ADD ONE TO IT // var g_iCount = 6; function startCountdown(){ if((g_iCount - 1) >= 0){ g_iCount = g_iCount - 1; numberCountdown.innerText = 'You must wait ' + g_iCount +' seconds before your download starts'; setTimeout('startCountdown()',1000); } } function top() { setTimeout('startCountdown()',0000); setTimeout('delayer()',6000); } function delayer() { window.location = \"http://www.mediaphiles.net/uploads/".$actualname."\" } </script>"; ?> Don't worry about the $actualname variable, that is working. What I have it doing is when you click a button it starts top() which starts the countdown. Then, after 5 seconds (6 seconds) it redirects. But it doesn't seem to be working. -- I'm new to Javascript so I have no idea what the problem is. Hey there world. I'm not one for making my own scripts, so not quite sure about the best way to go about doing this. I've got a form with 2 different sets of radio buttons. Upon submitting, I'd like to redirect the user to a certain page, based on the selections they made among the radio buttons. Thanks in advance. Hi all, I hope you can help I have some code which: 1) Opens a URL (e.g. google.com) in a hidden iframe, then 2) Redirects the visitor to a different URL (e.g. yahoo.com) after it has loaded... This works exactly as I need. What I'd like to do is the following: 1) Open a URL (e.g. google.com) in a hidden iframe, then 2) Redirect the visitor to a different URL (e.g. yahoo.com) in a full-screen iframe 3) The address bar of the full-screen iframe should be my domain (obviously!) Here's what I have so far... Hidden iframe -> New URL Code: Code: <html>
<body>
<script type="text/javascript">
var page_body = document.getElementsByTagName('body');
var myframe = document.createElement('iframe');
var id = Math.random();
myframe.setAttribute('id', 'myFrame'+id);
myframe.src = 'http://google.com'; //First open Google in hidden iframe
myframe.setAttribute('frameborder', '0')
myframe.setAttribute('width', '0');
myframe.setAttribute('height', '0');
if (myframe.attachEvent)
{
myframe.attachEvent('onload', function()
{
top.location = 'http://yahoo.com'; //Once loaded redirect to Yahoo -- but the address bar shows yahoo.com -- I want the address bar to display mydomain.com/page.html
});
}
else if (myframe.addEventListener)
{
myframe.addEventListener('load', function()
{
top.location = ('http://yahoo.com');
}, false);
}
page_body[0].appendChild(myframe);
</script>
</body>
</html>
I have an example of some code which displays the full screen iframe, but my problem is... ...I can't figure out how to redirect to this after the hidden iframe has loaded Here's an example of how I want the redirect to display -- after the initial hidden iframe has loaded: Code: <html>
<head>
<script type="text/javascript">
function sendParams() {
document.body.style.overflow = "hidden";
}
</script>
</head>
<body>
<!--Open Yahoo.com in a full screen iframe, and disable extra scrollbar -->
<iframe height="100%" width="100%" frameBorder="no" onload="sendParams()" src="http://yahoo.com"></iframe>
</body>
</html>
I've been beating my head against the wall today trying to figure this out, and I'm fresh out of ideas. If you can help, you'll have some serious gratitude and good karma thrown your way! Best wishes, and thanks in advance, Paul Hi, I rarely use javascript so pardon my newbieness. I'm trying to create a function that is triggered by a <select> onchange event. It's supposed to save the newly selected value in a variable, then refer the user to a link location + variable. This is what I tried: Code: <script type="text/javascript">
function categoryRef()
{
var a = this.options[this.selectedIndex].value;
document.location = 'recommend.php?cat=' + a;
}
</script>
<select name="category" onChange="categoryRef()">
<?php
$getCategoryQuery = "SELECT category FROM categories ORDER BY category";
$ConnectQuery = $database->query($getCategoryQuery);
while($category = mysql_fetch_array($ConnectQuery)){
if($getCategory == $category['category']){
echo "<option selected='selected'>" . $category['category'] . "</option>";
}
else{
echo "<option>" . $category['category'] . "</option>";
}
}
?>
</select>
When I try this and change option nothing happens. Any pointers? Hi, I want a link on my website where when you press it, it print screens. somthing like, <a href=printscrn();">Print Screen</a> anyone any ideas? Simon I've cannibalised some code from the jQuery supersized plugin that scales images to full screen size while retaining aspect ratio. However, I seem to be getting it wrong, and my maths is... well, appalling. The problem is that while it's resizing correctly to fit the width OR the height, it's not fitting the width AND the height. That is: If I adjust the window height, the image scales to fit the height, but goes outside the window width. If I adjust the window width, the image scales to fit the width, but goes outside the window height. If I adjust both (dragging the window corner) it seems to favour fitting the width. I am currently using only landscape images. I don't know if that has a bearing. This may well just be a logic issue, but my brain is just turning to jelly when I look at my code below: Code: var image_ratio = options.image_dimensions.height / options.image_dimensions.width;
var browser_ratio = browser_height / browser_width;
if (browser_ratio > image_ratio){
var target_height = browser_height;
var target_width = Math.floor(browser_height / image_ratio);
} else {
var target_width = browser_width;
var target_height = Math.floor(browser_width * image_ratio);
}
The code above works out some new image dimensions and is called when the browser is resized. The options.image_dimensions.height and options.image_dimensions.width variables represent the original dimensions of the image, and browser_height and browser_width are calculated from the window size. How can I make it fit either landscape or portrait images to the smallest available dimension of the browser? 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; ?> |
