JavaScript - Very Basic Mobile Javascript Browser Detection? Please Read!
Hello,
Is there a way with JavaScript to easily detect which mobile browser is being used? I would not normally ask this, but because we do not have the time or budget to implement any back end detection scripting it is our only option right now! I don't think we will need to detect which version of the browser, or which revision of the phone is used - just need to target each family to deliver the proper video type. Similar TutorialsHey, I'm working on a mobile website and need some help with my mobile browser detection script. I have it working for iPhone, iPod Touch, and Windows Mobile Devices. I need help getting it to detect for Blackberry Browser (Blackberry Devices), Blazer Browser (Palm Devices), Opera Mini Browser, Opera Mobile Browser, and other mobile browsers if possible. Does anyone know how to modify (and test if you have a phone to test with, as I don't have all of these devices) this javascript?: Code: if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)))
{location.replace("mobile.html");}
if((navigator.appVersion.indexOf("Windows CE")>0))
{location.replace("mobile.html");}
Thanks for your help! -Chris Greetings, I am currently using the websites tutorial about browser detection using the navigator. http://www.javascriptkit.com/javatutors/navigator.shtml I am however finding myself unable to detect a pattern in order to learn from. My aim is to use Browser detection to have a CSS file for each browser type, such as Firefox, IE, Opera, Safari and then an overall CSS file if none of the above, to fix numerous flaws. For IE and Firefox using the site's code is all well and good and while I haven't tested it yet I'm wondering how to set up the coding so that it can detect a safari browser. There are lots of slashes and d's and brackets and I do find myself unable to understand their purpose. So if someone can explain how I could do it for Safari I would be very appreciative. Hi all, Background: I'm currently working on a landing page which will display the same on both desktop & mobile devices, which is what we "want" for now. However, we've created an alternate registration page for mobile devices. This page can be accessed by clicking on a specific button, which has a class on it that will determine if the user is on a mobile device or not. If they are not, the normal action will occur, such as a registration popup, built specifically for desktop users. The problem is: I'm firstly having to use .remove to take away the class of pbx_ajax which operates the popup, so mobile users aren't affected by the popup and will continue onto the page we specially built for them. However, it seems my script is removing the class straight away, which prevents the popup from working for desktop users. Secondly, the script doesn't actually seem to work, it simply doesn't fire, which begs the question if i've cocked up my class bind. Code is attached below, please if anyone has any advice, do let me know as i'm at my wits end. Oh and i'm sure you'll notice, i'm polling for when the jQuery has loaded, as the library is located at the bottom of our site (its a rather large site). The javascript/jquery Code: //$(document).ready(function() {
//Global function that will detect what device the page is being viewed on
function globalDetectDevice() {
var deviceIphone = "iphone";
var deviceIpod = "ipod";
//Initialize our user agent string to lower case.
var uagent = navigator.userAgent.toLowerCase();
//**************************
// Detects if the current device is an iPhone or iPod Touch.
function DetectDevice()
{
if (DetectIphone()) {
window.location = "/landing/register/mobile" ;
}
else if (DetectIpod()) {
window.location = "/landing/register/mobile" ;
}
else {
return false;
}
}
}
//Binding the above function to a class, that we can then attach to any clickable element
//As jQuery is at the bottom of page, we poll the function until jQuery has loaded, once loaded, we clear the polling using clearTimout
var bindTimer = setInterval(function() {
if ("undefined" != typeof jQuery && globalDetectDevice) {
$('.detectDevice').removeClass('pbx_ajax').bind('click', DetectDevice);
clearTimeout(bindTimer);
}
}, 50);
//}
the html button Code: <a class="detectDevice pbx_ajax" title="Join Free" href="?cat=popup&action=open&settings=pbx_popup_register">~graphic("btn-get-started-prints-LP")</a>
thanks for any help i don't know what has changed in last releases of Firefox and Opera but before i used this script to detect browser versions (IE, Opera, FF) and block or redirect depending on version Code: <script language="javascript">
<!--
//Detect IE greater than 1 - we are blocking it completely
version=0
if (navigator.appVersion.indexOf("MSIE")!=-1){
temp=navigator.appVersion.split("MSIE")
version=parseFloat(temp[1])
}
if (version>1)
window.location="ie-error.html"
//Detect Opera less than 10 (9.80)
if (navigator.userAgent.indexOf("Opera")!=-1){
var versionindex=navigator.userAgent.indexOf("Opera")+6
if (parseInt(navigator.userAgent.charAt(versionindex))<9.8)
window.location="op-error.html"
else (window.location="index2.html")
}
//Detect Firefox less than 3.6
if (navigator.userAgent.indexOf("Firefox")!=-1){
var versionindex=navigator.userAgent.indexOf("Firefox")+8
if (parseInt(navigator.userAgent.charAt(versionindex))<3.6)
window.location="ff-error.html"
else (window.location="index2.html")
}
// -->
</script>
it worked last with Opera 9.5, FF 3.0 but after that it doesnt work at all Firefox'es version (3.6) doesn't get detected and is redirected to error page same goes with Opera (9.8 which is 10.0-10.5) can anyone tell me why this happens ? or can anyone "fix it" i know many people are against this kind of scripts (blockers and redirecters) but i do it so people who come with older and less compatible browsers with W3C standards to get warned so they don't load deformed page I have a website (www.andrewburns.net.au) that displays differently according to OS. Currently in OSX the text in the menu lines up with the image text of the site title - this is what we want to have happen and it looks fine across all browsers using OSX. However, in Windows it's offset by about 10px, and similarly displays the same offset in all Windows browsers incl Chrome, FF, Safari, and of course ie. I'm trying to use javascript to sniff out the OS and display alternate css accordingly. I'm not a JS coder at all and a friend who is has got me this far... Code: var isms=( navigator.appVersion.indexOf("Windows") != -1);
document.write("Browser Version: " + isms);
if(isms) $('DIV .menu').css('left','100px');
What I'm not sure about is where to put it to make it work given there is a fair amount of other scripts operating on the site. Is there anyone out there who can have a look at the site/source code and offer any insight/suggestions/solutions? I'd really appreciate it... I'm under a fair bit of pressure from the designer to get it pixel perfect and this is the last aspect of the site to sort out before I can sign it off. Thanks hey guys i'm making a lunar lander game using javascript.i want the player to land the spaceship on a black line i've drawn. but i have problems getting it right.when the player lands it properly in the line i want it to display a dialogue box which says u landed it perfectly.but the problem is even if i land it outside the line it gives me that message.so after spending sometime with it i figured out that my if statement is not working properly.it doesn't take the value from my x axis and only considers the value from my y axis.for eg lets say i drew the line from 560px to 600px on the x axis and its located at 700px on the y axis and this is my if statement if((TopPos>695)&&(rightPos>560)&&(rightPos<600)) { alert('you landed perfectly') } this is supposed to work but if i go above 600px but still maintains the height above 695 it says i have won.i have included the code could some point me out where i'm making the mistake thank you .

Hi, I need a javascript that detects flash and replace z-index value. i have 2 div. div1 (alternate HTML content) has z-index=-3 and div2 (flash object) z-index=0. If flash is detected, do nothing. if flash is not detected, i would like to set div1 z-index to a positive 3. can someone please help me? Hi, everyone! I am a freshman in the JavaScript area. One thing i am wondering recently is that whether JavaScript can get a data from the sensors as accelerometer, gyroscope or orientation sensors of a mobile device? From as a iPhone, iPad or some other Android system mobile phones, may i just use JavaScript to get the data from their sensors? Looking forward the replies from anybody. Thanks a lot! Best regards, Borui Hello, I have a question what is the best way to identify a browser, browser version and OS in javascript. I have try a few scripts but they all fail. This will help me out formating the code for diferent browsers. Thanks Ok, I am currently working on an announcements portlet for a dashboard that my team is creating. What is desired is to be able to have this portlet access a stored text file (file can be edited so content is subject to change) that will have all the information needed for these announcements. The JavaScript will then write it into a html file. I am a novice at html, and javascript; and i was hoping that if anyone had any advice, ideas, or a helpful link that could point me in the right direction I would much appreciate it. Hey guys! New user here and I just need a little help with some basic Javascript I must write a function that 'shows' the corresponding part of the form depending on what the user has selected. So... for example, if I select 'Pizza', the div #section2 with the question about Pizza type should be shown. All the sections that are not selected should be hidden. For example, if 'Mexican' is selected, the sections for 'Pizza' and 'Thai' should be hidden. I want this function to also display a message in the JavaScript console indicating which food type is selected. Apparently I'm supposed to use 'console.log("")'??? I'm using an external javascript file called prac8.js If anyone has any idea how to do this I'd be very greatful Code: <!DOCTYPE html>

Hi, I'm trying to create a video box on a website that plays a youtube video and then automatically plays random recommended videos with no break in playback. An endless playlist created by youtube based on the initial video. Youtube uses Javascript API. I have never used Javascript before but i'm just trying to get the video to play as above. There are few tutorials online and I couldn't find anyone trying to do a similar thing. If you have any idea how i'd go about it or if not where i could find some information to help. Thanks. Hi, I've just started learning JavaScript - actually started about half an hour ago. I have an extensive knowledge of Lua (if you've heard of it), so the concepts of programming aren't new to me. This code isn't doing anything. The HTML code makes the hyper-linked pictured show, but it doesn't do anything when the mouse rolls over it. The JavaScript code is saved in scripts/titleImage_rollover.js, and I'll show the HTML code as well. JavaScript: Code: <!--
// image rollover for header
function image_rollover(){
//show a set of random images
switch(math.floor(math.random()*5+1))
{
case 1:
document.getElementById("logo").src = "images/t2m_logo.png";
break;
case 2:
document.getElementById("logo").src = "images/pighead10_halloween.png";
break;
case 3:
document.getElementById("logo").src = "images/pighead10_easter.png";
break;
case 4:
document.getElementById("logo").src = "images/pighead10_classic.png";
break;
case 5:
document.getElementById("logo").src = "images/pighead10_combat.png";
break;
}
}
//reset image to normal
function image_reset(){
document.getElementById("logo").src = "images/pighead10.png";
}

Also, is there a way to view some kind of output in JavaScript? I am having trouble with JavaScript code and do not know why it is not working. I have the code I think is right but it is not showing up in my browser when run. Any ideas? Also are there any other ways to read in an xml file using javascript? please list if so. Hi, i have a question, is JavaScript can read an external file? i have an ear file, can it read external file without the external file compile together in the ear file? can we do so? I wants to access server web page which data is continuously growing(streaming data), I want to buffered some of that data write it in responseText then again get next buffered data write it and so on (in AJAX). Is it possible? if yes how to do that? This is a must-read for all users posting to the JavaScript forum, especially if you're looking to get help. A lot of you are posting in a manner that makes it extremely difficult- if not impossible- to respond to. Below are a list of posting guidelines and tips we ask that you please read- and FOLLOW- when asking for help: 1) Type in a subject that summarizes your question! - The fastest way to turn off other members wanting to help you is to type an incomplete or silly subject for your post. Examples of poor subject titles include: - "Help!" - "I'm a newbie...please!" - "Is this possible using JavaScript?" - "loops" - "Urgent...deadline tomorrow!" - "A challenge for you JavaScript masters" The above subjects either have absolutely nothing to do with the question itself, or are grossly incomplete (ie: "loops"). When asking for help, enter a subject that summarizes your question, period! Don't use silly, incomplete, or "bait" subjects. 2) Be descriptive and articulate when asking your question! Some of you are posting as if we're all psychics, and are supposed to grasp your question with the little or confusing information you've provided in your question. We cannot read your mind, and putting up a post like "Can someone help me with arrays?" or "How can I get the slide-in slideshow to work on my site?" is not nearly enough information to go by. What exactly do you want to know about arrays? Which slide-in slideshow are you referring to (the one written by Bill Gates?)? Set us up with some crucial background information, what you want to do, and what the problem is. Be concise and precise. Also when posting, understand that you're trying to convince others to help you. Be articulate and have respect for the English language! Check for spelling/grammar mistakes, and try and format your question and code in an easily legible manner. Big tip: Use the preview button often. Bottom line- put yourself in our shoes, and try and phrase the question so it's clear and easy to respond to. 3) Do your homework first. Only post the part of the script you're having trouble with! There are generally two types of people- ones that simply dump their entire page or problem and expect everyone to spend hours solving everything for them, and those that do their own homework first, and only ask very specific, manageable questions. The later invariably gets more and better responses from others. When you're lazy, do not expect us to be hardworking for you. As an example, lets say you're working on a long script that uses the "switch" statement of JavaScript, and it's returning errors. You could either: i) Post the entire script and simply say "Please debug this script for me!" ii) Or, localize the problem yourself first and post instead "Can someone tell me the syntax of the switch statement in JavaScript?" The second question will get a LOT more quality responses, as it is concise, manageable, and not overwhelming. Remember, ask for the world, and you'll get nothing. Ask for a little, and you'll get a lot. 4) Use the search feature often to make sure your question isn't already answered- The longer this forum has been online, the more solutions it accumulates. Always search past posts first (using the search link to your upper right) to make sure your question isn't already answered. Use 1-2 keywords as the search terms. 5) Know the capabilities and limits of JavaScript before posting. Please familiarize yourself with what JavaScript can- and cannot do- before posting. Many people are posting JS questions that simply cannot be accomplished using the language, period. JavaScript is a client side language, and cannot manipulate the server end in any way, such as saving data to the server, accessing a database etc. JavaScript works strictly on the user end, such as popping up a window, applying an image rollover effect, or determining user screen resolution (*without* the ability to pass this info back to the server). If JavaScript is completely new to you, please familiarize yourself somewhat with the language, by visiting the below links - JavaScript questions and answers list - JavaScript tutorials - Advanced JavaScript tutorials - Pre-made JavaScripts (illustrates typical JS applications) 6) Be appreciative and follow up when getting a response. Everyone here is volunterring their time to help out others. The least you can do is be appreciative and follow up when getting a helpful response. If you've solved your problem, let people know so they don't continue spending time on your question. Saying a little "thank you" goes a long way. Hi so i am using onClick="myPopup(); on a button and when someone clicks on the button, it pops up an advertisement in a new tab. But is there a way to make the users stay on the page where the button is located instead of forcing the browser to automatically switch to the advertisement tab when a button is clicked? This must be very simple. I want to execute some javascript only if an element is not displayed What is the syntax? if("#element:hidden) { do something like show it } Help much appreciated. Hey guys. I am pretty new to JS and programming. The company that I am working for put me on this project and I have a question. Here is a snippit for a form that we have. We use a dreamweaver extension "HDW form to database" to process the forms and put them in a mysql database. the wpform() is a validation function that has been written. what I want, is the fallowing, if you look at the code below in the option object, there are different categories... rock, funk, hip hop, synth etc. i want it so when one of them is selected, it goes to a different respected page. for example, if the value Rock is selected, and you press submit, it would take you to www.google.com . On the other hand if the value Funk is submitted, it will take you to www.yahoo.com . Code: <form action="/HDWFormToDatabase/FormToDatabase.php" method="post" name="theForm" onSubmit="return wpform()" accept-charset="iso-8859-1">
<select size="1" name="genre">
<option selected="selected" value="genre">Choose a Genre!</option>
<option value="Rock">Rock</option>
<option value="Funk">Funk</option>
<option value="Hip Hop">Hip Hop</option>
<option value="80s">Synthesizer</option>
<option value="Techno">Techno</option>
</select>
<input type="hidden" name="hdwok" id="hdwok" value=" URL GOES HERE" />
</form>
Normally, when this option object is not present, the user presses submit and after the form gets processed to the database, the browser forwards to the "URL GOES HERE" value. However, I am not sure exactly what to do now since the URL which it is forwarded to will change. can someone give me a hint on how to make this happen? just some general advice for a newb? I would write it but I am pretty lost. I was thinking of including a if statement in the wpform() function that goes something like: Code:
if (document.theForm.genre.selectedIndex == 0)
{
alert("Please select your genre.");
document.theForm.genre.focus();
return (false);
}
if (document.theForm.genre.selectedIndex==1)
{
window.location = "http://www.google.com/";
return(true);
}
if (document.theForm.genre.selectedIndex==2)
{
window.location = "http://www.yahoo.com/";
return(true);
}
etc etc Would this work? Is there a more efficient way of doing something like this that I should know of due to my lack of JS skills? Thanks in advance so much for help. |
