JavaScript - How To Detect If An Add-on Is Enabled (firefox)
Hi all,
The code I am working on uses the idea of detecting mime type support, to see if the add-on is there. Then if the mime type is not supported, it assumes, the add-on is not installed. (No other add-ons have this mime type.) However, there is a problem, if someone disables the add-on, the there is no mime type handler in navigator.mimeTypes['the/MimeType']. Is there some way to detect if an add-on is installed, and also if the add-on is enabled? Thanks, Grae Similar TutorialsWe all know AC_OETags.js. URL like: http://www.adobe.com/products/flashp...detection_kit/ How to make flash detection in variable with valu true or false if it is (not) detected to use in PHP applications? Hey guys, i'm trying to set up a favorite system for my website and I'm using ajax to do an async request to the server to run a php script. The problem is that i'm running joomla with sef enabled. So whenever i'm on a page the URL looks like: mysite.com/Category-Name/Item-Name/ when i click on the favorite button it will look like this mysite.com/Category-Name/Item-Name/favorite.php?all-the-stuff-that-is-being-sent-to-the-file This obviously doesn't work... I followed this tutorial: http://woork.blogspot.com/2007/10/in...sing-ajax.html My question is how do i fix this.. can i get the base URL or something? I am a TOTAL noob to javascript. i somewhat understand it, but i have no clue what i'm doing. I just have basic programing knowledge through MATLAB and PHP... BTW, the key here is not to leave the site Thanks for the help in advance EDIT added my domain name in front of the location of the file and fixed the problem =) The navigation for the web site I'm doing requires JS to remotely work so I want to make some kind of back-up scenario. Basicly, how can I make it so my main navigation will only display if there is script? One thought I had was put it in a div, hide it in the CSS, then use JS to show it but if there is a better way to do this I'd like to know. Hi all. This is a generic question as Google didn't help at all, does anyone know how to check if javascript is enabled and then I want to display info based on that. I don't mind how I do it, HTML, PHP or whatever Regards, Magnetica Hi, I'm just wondering if I can do a check on my page to determine if users have javascript enabled, and if not, redirect them to a different webpage. My site requires javascript, and without it, all the jquery popup boxes and stuff overlap, so I'd rather the user just not see any of that at all. Hi, I'm wanting to make a submenu appear on the page when a menu item is mouse-overed. I can find examples online where UL and LI are used, but that won't work in my layout: http://www.girlscoutsmoheartland.org/newpagetest.php Here, the menu items like "home" and "for girls" need to generate a horizontal submenu below where "menu item A" and "menu item B" are, and each submenu would appear in the same location as the other submenus, disappearing and appearing as a different menu item above is hovered over. All I can find are like this: http://htmldog.com/articles/suckerfish/dropdowns/ and I can't figure a way to conform that to this layout. Can someone point me to a site that has a solution for this situation? Thanks! Liam Hi all, I am writing an administration panel for a web site. I want to check if the client's browser javascript enabled and if it is not enabled, a warning DIV comes telling the client to enable javascript and disable the actual page (make the actual page non-usable). Is there a way to do that? Thanks in advance telmessos I have an auto submit form example.. Code:
<form name = "backtosource" method="POST" and the rest of this is fine>
blah blah
</form>
<script type="text/javascript">
function process_data_return()
{
document.backtosource.submit();
}
</script>
<script type="text/javascript">
<!--
process_data_return();
// -->
</script>
so this works for everyone of my people other than one who is on a debian server, we all use centos. i know this is cleint side but i wanted to mention that. this user has the js enabled on all his browsers. so what would cause his browser not to execute the js auto submit, we know this to be the issue but cannot resolve. thanks i guess i could try the old cdata wrap trick Code: // <![CDATA[ js code // ]]> but i dont want it to affect those that this is working. What is a good switch value to use so i can build an if statement. Is there a current local value i can trap for comparison Hello, I would like to know how to make a website (in this case, a parent div) viewable only if JavaScript is enabled? I tried to develop a code that can do this, but could not find the solution. Code: <html>
<head>
<script type="text/javascript">
window.onload=function()
var="true"
if(JavaScript.enabled)
{
document.getElementById('true')
}
OnClick()
{document.getElementById('toggle').onclick=function()
{document.getElementById('jahava').style.display=(document.getElementById('jahava').style.display!='none')?'none':'';}}
</script>
</head>
<body>
<noscript>You must have JavaScript enabled to view the website.</noscript>
<div id="jahava">Contents Here</div>
</body>
</html>
Hi, a friend of mine has a problem on several (German) Legend of the Green Dragon (lotgd) servers. Sometimes, mostly after she has loged in and out for a few times during a day, she suddenly gets the message that Javascript must be enabled to log in. But it definetely IS enabled - otherwise she'd never be loged in! The error occurs - on 2 different PCs - with 2 different internet providers - with IE, FF and Opera - only on lotgd servers - any other page using Javescript are working fine We - updated and downgraded Javascript - disabled and/or uninstalled all antivirus and firewall programms - cleaned cache with CCleaner - disabled browser add ons - reinstalled Windows - disabled auto-insert passwords Even a reboot doesn't change anything. Sometimes, when she waits a few hours, she can log in again. Sometimes the error doesn't occur for days, sometimes it's there every day. That's why it is so strange. Although she doesn't change anything, the error comes and goes completely irregular. The games' admins can't or don't want to help, they say that she's the only one with that problem and that it's not a mistake in the script. What might occur that error? And what can we do to stop it?? That's what the Opera error console says: JavaScript - http://lotgd.demonstone.org/index.php Inline script compilation Syntax error at line 21 while loading: b|(~d)),a,b,x,s,t);}*/ --------------------^ expected expression, got '*' CSS - http://lotgd.demonstone.org/templates/yarbrough.css Linked-in stylesheet xbackground-color is an unknown property Line 1: eight:auto;padding:1px;line-height:18px;float:left;clear:none;xbackground-color: --------------------------------------------------------------------------------^ JavaScript - http://lotgd.demonstone.org/index.php Inline script compilation Syntax error at line 21 while loading: b|(~d)),a,b,x,s,t);}*/ --------------------^ expected expression, got '*' JavaScript - http://lotgd.demonstone.org/index.php Uncaught exception: ReferenceError: Undefined variable: calcMD5 Error thrown at line 1, column 0 in <anonymous function>(event): document.forms.loginform .hidden_pw.value = calcMD5(document.forms.loginform .password.value); JavaScript - http://lotgd.demonstone.org/index.php Inline script compilation Syntax error at line 21 while loading: b|(~d)),a,b,x,s,t);}*/ --------------------^ expected expression, got '*' JavaScript - http://lotgd.demonstone.org/index.php Uncaught exception: ReferenceError: Undefined variable: calcMD5 Error thrown at line 1, column 0 in <anonymous function>(event): document.forms.loginform .hidden_pw.value = calcMD5(document.forms.loginform .password.value); JavaScript - http://lotgd.demonstone.org/index.php Inline script compilation Syntax error at line 21 while loading: b|(~d)),a,b,x,s,t);}*/ --------------------^ expected expression, got '*' JavaScript - http://lotgd.demonstone.org/index.php Uncaught exception: ReferenceError: Undefined variable: calcMD5 Error thrown at line 1, column 0 in <anonymous function>(event): document.forms.loginform .hidden_pw.value = calcMD5(document.forms.loginform .password.value); JavaScript - http://lotgd.demonstone.org/index.php Inline script compilation Syntax error at line 21 while loading: b|(~d)),a,b,x,s,t);}*/ --------------------^ expected expression, got '*' I hope someone is able to help. Thank you! 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! 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. 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 really want to learn a way determine whether custom fonts via @font-face got downloaded by the client machine and then set styles differently depending on whether they got the fonts or not. To start I could run a fonts-inactive.css file to setup the styles to look nice without custom-fonts (this is the base style which should look fine without any JS, flash, custom fonts, etc.). Then run a JS that will run the font-face-rules.css (which attempts to load the fonts via @font-face css rules) - this way if JS isn't active then no fonts will be loaded and the document will default to its fonts-inactive.css. If the JS does run then font-face-rules.css will try to send the fonts. So the JS needs to somehow determine whether the fonts worked or not. If the fonts worked then the JS would run the fonts-active.css which would alter some style rules to make the page look better with the custom fonts (since we know they got the fonts we can tweak the page a little to look better with them). If the fonts didn't work then the JS needs to not run the fonts-active.css and instead just exit out leaving the document with its original, unaltered rules from fonts-inactive.css. (since we know they didn't get the fonts we leave them with the baseline stylesheet which optimizes the appearance for default fonts). Sadly I don't know the first thing about Javascript so I am hoping that you guys might be able to help me come up with something that works. Cheers, line 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! i have a problem. i want to check that whether an element with a specific id exist on page or not. example Code:
<script type="text/javascript">
function bgcolo()
{
if(document.getElementById("jj") == null)
{
return red;
}
else
{
return green;
}
}
</script>
</head>
<body>
<table width="100%" border="1">
<tr>
<td id="oo" bgcolor="return bgcolo();">bvbv</td>
</tr>
</table>
<div id="jj">fggftrytyyyyyyyyy</div>
</body><
Hi, I am currently detecting for Shockwave within IE by doing the following: Code: var isInstalled = false;
if (window.ActiveXObject) {
var control = null;
try {
control = new ActiveXObject('SWCtl.SWCtl');
} catch (e) {
return;
}
if (control) {
isInstalled = true;
}
}
This works as expected and if it fails to detect Shockwave I tell the user to install Shockwave. The problem comes when AcitveX is disabled as it still returns the same message that it's not installed. I would prefer to be able to include an extra step to detect if ActiveX is disabled, in which case I can tell the user to enable it rather than giving them false advice. My only idea would be to detect for an ActiveX Object that every IE user should have installed. Any ideas on what that ActiveX Object could be or any ideas on how I could tackle this problem are greatly appreciated. Thanks Hi.. Anyone can help me to reslove tis..
