JavaScript - Loading A Css File Based On Browser Being Used
Hi,
I have some code that performs differently in Opera than it does in any other browser. So I have a stylesheet specifically for opera. Is there a way to do something like this, where I check the browser, and if it's not opera, then load the default sheet, otherwise load the opera-specific css? Code: <script>

As of this writing, that code seems to break my page, as if it doesn't like loading a sheet based on an if/else clause. Similar TutorialsHi Guys, I have an situation. An DIV has two sections, one to prompt user info and other displays ads. While the ads section is in an iframe(inside DIV) whose src is set dynamically, i.e. when user tries to close the browser, then my code brings up the DIV and sets the src of that iframe also an browsers default prompt stays on top of the page asking for 'Ok' and 'Cancel' button to leave/stay on the page respectively. My problem is that the iframe is not loaded unless user clicks on the 'Cancel' button. This happens in IE,Chrome and Safari but works fine in Firefox. I know this is an browser's behavior but still expect an cross browser solution. Is there a way to tell Javascript to load data or a php file the re-direct to that page? Right now i have a script that will re-direct when a user comes to the page. It waits about 5 seconds to give it time. I wanted to know if there was a way to load it with JS or AJAX. Thanks for any help. Hey guys, I currently have a flash header .swf file as the header in my webpage. Problem is, it's 300 KB so it loads after everything else has already loaded, leaving a huge blank space where the .swf is suppossed to be until it finishes downloading. Is there a way I can tell my page to pre-load the .swf before everything else so that all elements in my page look like they load at the same? For example, with images I can do something like this: function MM_preloadImages() { //v3.0 var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array(); var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++) if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}} } then: <body onload="MM_preloadImages('images/search.jpg','images/contact.jpg','images/home.jpg')"> Is there something like this for .swf? 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. I'm still struggling for a solution here. I have a background image that auto-resizes based on browser window / screen resolution. I want my top header menu, which requires links, to act in the same way and be in roughly the same position/size based on browser window. Is this possible? In the sample below, the image is just part of the background image to give you an idea of the look I am trying to duplicate. Is there a Javascript out there that will help me or will I be stuck having to rework my design? http://www.uberbotjones.com/sanny/test.html This site is really driving me crazy. Hello, I am looking for a way to select a file from a list and load it into a webpage. The page and the files are stored on a sd-card for off-line usage, I know that listing files remote dynamicly needs a scripting engine but since the sd-card is on the client side that is not possible, but I can make a list of those files when creating them. It is intended for a datalogger on a tractor-puller, I create csv files with a bash script on the logger and for off-line viewing I use a javascript charting engine which loads the csv file, the files have the creation date as filename and I can make (and maintain) a list of files when creating them. The plan is that the we can select another data set (run) from within the browser and show that one. I have setup an example at http://www.dlogger.deserver.nl/test/ If someone can help me out this year starts good! What I mean by this is how do you load an xml document that has been inputted as a string in a form. I would've assumed it was something like this, but this doesn't seem to be working. Code: <html>
<head>
<script type="text/javascript">
function loadXML(file) {
var moz = (typeof document.implementation.createDocument != 'undefined');
var ie = (typeof window.ActiveXObject != 'undefined');
var xmlDoc;
if (moz)
xmlDoc = document.implementation.createDocument("", "", null);
else if (ie)
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.load(file);
return xmlDoc;
}
</script>
</head>
<body>
<input type="text" name="input1" size="15"/>
<input type="button" value="LOADXML" loadXML(input1.value)"/>
</body>
</html>
Where 'input1' would be an xml file in the same folder. ok guys im going to be honest here, i know nothing about javascript. ive been learning php and even that gets confusing at times. my issue: i bought a script off someone(php site) and it has a .php file that using .js files he had no idea how to fix the issue so im hoping you guys can help me fix it. this one .php page includes another .php file and 2 other .js files. i dont want to go and post every single file as one of them is like 1200 lines (i have if you like to hunt for errors) is there some code i can add in to make it show where its getting an error? i know you can in php and mysql the page get stuck on Loading... on the .php file which is line 647: AJS.setHTML(AJS.$('load'), 'Loading...')

Hi, I was working on my web page and noticed that depending on the width of the screen, the Iframe I created would not display correctly. Because of that I needed to come up with a piece of code that would detect the screens horizontal resolution and pick the right Iframe to be loaded. Below are the scenarios that specify which one should be loaded. I am very bad with javascript so could someone help me come up with a piece of code that would load the right frame? Thanks. The web address where the code will go is www.jumbledfun.com/nasa.html. If the horizontal resolution of the screen is less then 1600 I would like this Iframe to be loaded: (It Would Go Under The If Part) Code: <iframe src="http://www.jumbledfun.com/nasaframes/nasalivelr.html" width= "55%" height= "580%" scrolling="no" frameborder="0"/> </iframe> If the horizontal resolution of the screen is 1600 or more I would like this Iframe to be loaded: (It Would Go Under The Else Part) Code: <iframe src="http://www.jumbledfun.com/nasaframes/nasalive.html" width= "100%" height= "300%" scrolling="no" frameborder="0"/> </iframe> This is the format that I would want it in: Code:
<script type="text/javascript">
if (condition)
{
code to be executed if condition is true
}
else
{
code to be executed if condition is not true
}
</script>
I am very inexperienced with javasciprt. I am designing a form in coldfusion, and want some dynamic action to take place. My users will be offered 2 selections via radio buttons. Depending on which radio button they select, they will get a few more radio buttons to choose from. I have been told that this can be handled in javascript. So I am appealing to the javascript programmer nation for some assistance in this endeavor. Any help would be greatly appreciated, Thanks. Hi, I'm currently working on my portfolio website and would like to have information about my movie clips be retrieved from an XML document when a thumbnail is clicked. I am building my website in HTML and would like to retrieve the Xml using JavaScript. Any help would be appreciated. My XML is valid and structured as such: <?xml version="1.0" encoding="UTF-8"?> <work> <motion> <reel> <title id="Demo Reel 2009" project="Self Promotion" client="Self"> <![CDATA[This demo reel is primaraly a collection ......]]> </title> </reel> . . . . These are my initial variable definitions and readXML function in javascript: <script language="javascript"> var xmldom, workNode, motionNode, printNode, fineartNode, displayNode, titleNode; function readXMLDocument() { xmldom=createDocument(); xmldom.async=false; if (xmldom.parseError != 0) { alert("An error occurred: \nError Code " + xmldom.parseError.errorCode + "\n" + "Line: " + xmldom.parseError.line + "\n" + "Line Pos: " + xmldom.parseError.linepos + "\n" + "Reason: " + xmldom.parseError.reason); } else { alert("Document: " + xmldom.documentElement); alert("Root: " + xmldom.documentElement.tagName); alert("Child: " + xmldom.documentElement.firstChild.tagName); alert("Xml DOM: " + xmldom.xml); } xmldom.load("workinfo.xml"); workNode=xmldom.documentElement; motionNode=workNode.firstChild; printNode=motionNode.nextSibling; fineartNode=printNode.nextSibling; } . . . . A call to function revealText is called "onClick" of a thumbnail as such: <a href="videopages/reel.html" class="vid" target="video" onClick="revealText(0)"> This is function revealText: function revealText(x) { var title, project, client, info; readXMLDocument(); displayNode=motionNode.childNode[x]; titleNode=displayNode.firstChild; title=titleNode.getAttribute("id"); project=titleNode.getAttribute("project"); client=titleNode.getAttribute("client"); info=titleNode.getNodeValue(); titleSpan.innerHTML=title; projectSpan.innerHTML=project; clientSpan.innerHTML=client; infoSpan.innerHTML=info; } </script> and these are the spans they are written to: <span id="titleSpan" class="vidinfo"> <span id="projectSpan" class="vidinfo"> <span id="clientSpan" class="vidinfo"> <p id="infoSpan" class="content"> If you have read this far, I REALLLLY appreciate it. And any ideas as to what is wrong would help alot. Hi, I have a JS file on site A which needs a few parameters from a short text file on site B. Since crossing domain boundaries in JS is problematic, the way I do it is that the JS actually opens an intermediate PHP file on site A which redirects to the destination page in site B. Here's how it goes: The call is made through: Code: On SiteA.com/myfile.js
var theFile = getFile("intermediate.php");
var lines = theFile.split("\n");
var var1 = lines[1];
var var2 = lines[2];
var var3 = lines[3];
On SiteA.com/intermediate.php:
<?php
include("http://www.mySiteB.com/theTextFile.txt"); ?>
The problem is that this takes a long time. I would really like to speed this up. For example - I thought of using a direct IP address, so that there won't be any need a DNS server (using Code: include("http://123.45.67.89/~myUsername/mySiteB/theTextFile.txt");
) but this would expose me to hackers as it would make my Hostgator username visible. According to HG support the above format is the only way to access my subsite via direct IP. Any ideas on how to speed this up, either by bypassing DNS (but without exposing username) or by offering another way of reading data across sites? Suggestions for both JS and PHP files would be appreciated. I cannot set up a CDN here. This is really important for me! THANK YOU!!! im trying to onclick function on the button but in firebug it will say, function not defined, i even tried to do it with a internal script, but still it will not work. please help Code: <!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="s/i.js">
</script>
</head>
<body>
<button id="fihkhjsdk" onclick="ff();"> dsfh </button>
<php code...>
</body>

How to detect if the user clicked cancel while uploading a file ? Is there an event for it?
So, I have to rely on a third party external JS file to load into a site of mine. Problem is I have to have it (for ads), but once every blue moon the server fails to repond to the request (its down or unresponsive), and thus because the JS can't load, the site hangs. Is there a reliable js/ajax etc.. mechanism that I can use to set an allotted time and if the js isn't loaded, cancel the call or stop it so the page can load? Please advise. Caveats: I cannot host it, I cannot use php. Basically I was given a script call and I include it in the header of the page. I don't have alot of room to host, use various technologies etc.. other than what I am able to use without any backend/app scripting. I'm looking for a code like these news tickers you see on TVS nowadays at the bottom of the screen, where they show you the latest headlines. I want a simple scrolling marquee text that shows the text based on a txt file with the ability to insert an image between every line So I was reading up on how to load and parse an XML file into an html page and I found through w3 a great tutorial with sample code: http://www.w3schools.com/xml/xml_dom.asp It appears to work fine on their website but when I try it from my desktop it doesn't work. So what I have is an html file with contents: Code: <html>
<body>
<h1>W3Schools Internal Note</h1>
<div>
<b>To:</b> <span id="to"></span><br />
<b>From:</b> <span id="from"></span><br />
<b>Message:</b> <span id="message"></span>
</div>
<script type="text/javascript">
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","note.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
document.getElementById("to").innerHTML=
xmlDoc.getElementsByTagName("to")[0].childNodes[0].nodeValue;
document.getElementById("from").innerHTML=
xmlDoc.getElementsByTagName("from")[0].childNodes[0].nodeValue;
document.getElementById("message").innerHTML=
xmlDoc.getElementsByTagName("body")[0].childNodes[0].nodeValue;
</script>
</body>
</html>
And then the xml file named "note.xml": Code: <note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note> I have no idea what I am missing or not seeing that is causing this not to work but if anyone knows I would appreciate the input. For the record I have tried this in chrome and ie. hi, I have a website which is available on internet and uses lot of javascript code. Someone recently reported a bug and I fixed it in a javascript file. Now I want to move this updated js file on my server. but I am confused, how will this fix now be downloaded on every user's browser when they access website the next time? Is the download to client machine dependent on browser settings? could it be possible that some customer machine has latest file and some do not. How do I force file to download on client machine independent of client browser settings? thank u Hi there, Can anybody help me to write php/javascript code which will allow users to open files directly from web browser into desktop application? Here is the specification: I have a photo editing business with many people working in Photoshop. I am currently developing a web based application (joblist) using Javascript and PHP which should allow the photoshop designers to browse and open files/images directly from joblist/web browser into photoshop. The reason I want this instead of browsing folder is that I have a database where I store who worked on which file, when and how long it took. The concept is that, designers will select a file and click on start, as soon as they click on start the original file will open in Photoshop and there will be an entry into database (using PHP). Once they finish the task they will close the file and click on Finish button. My joblist application will be published in a local server and the file will be open on a local network, so when they save the file it will be saved where the source file is located in (local server). The application should work in both PC and Mac. I have already done all other part of the application except file opening directly from browser to desktop application functionality. Anybody can help me to write the code (PHP or Javascript) which can open the file from browser (local server) directly into desktop application e.g. PHotoshop or Illustrator? Thank you very much I look forward to someone's real help! Best regards Mr. Sumon |
