Configuring A Script - Detect Whether @font-face Is Supported By The Browser

Nov 20, 2009

So I have this script that will let me detect whether @font-face is supported by the browser. Once this script runs then isFontFaceSupported() // will return a boolean indicating support.

So I just want to load a single .css stylesheet if isFontFaceSupported returns a 1, and if it returns a 0, then it does nothing, finished.

Here is the script.

The following is a font-face glyph definition for the . character:

Detect Font Used By Browser?

Apr 16, 2005

my CSS style is:

.text{font-family: Gill Sans MT, Verdana, Arial, sans-serif;
font-size: 12px;}

But Gill Sans is by nature much smaller than Verdana at the same pixel size.

So IF the browser does not have Gill Sans, I want to change the font size to 10pixels.

Is it impossible?

JQuery :: Set The CSS3 @font-face Operation

Sep 13, 2010

I have tried this without success:

$("@font-face").css("font-family","myCustomFont");
$("@font-face").css("src","url('myFontLocation')");

trying to emulate the expected CSS3 statement:

@font-face {
font-family: "myCustomFont";
src: url("myFontLocation");
}

Is this possible? If so what is the exact syntax?

Searching found no clear answer, though I ran across Cufon and similar libraries, but I would rather stay in jQuery if possible.

Detect The Current Font Size?

Jan 5, 2011

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.

<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:

<font size="+1"><span style="position:relative; bottom:-10;">

if the font size was +6:

<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..

Detecting Default Browser Font And Size

Jul 18, 2006

I'm curious if it is possible to detect the browsers default font and
size? Most of the posts on this topic predate Windows XP, IE 5.5,
Mozilla Firefox, et al.

I've searched up and down the DOM properties, looped through most
objects and collections alerting properties and values, and I can't
find anything. This leads me to believe it is not possible to detect
the browsers default font settings.

Event Listener For Browser Font Size Change

Aug 20, 2006

The problem:

I have an XHTML STRICT page which has some event listeners attached for onload and resize. I'm doing a bit of Javascript DHTML on these events. When a user changes the browser font size, the javascipt function needs to run. Although the TOPMENU DIV gets resized when the font changes size, its not a page resize so the function doesn't get run. I fixed this in IE6 by using a second function which is run onload and sets an event on the div object in the page after its been defined.

Problem is this doesn't work in Firefox.

Mozilla DOM reference says there is no resize event on a DIV so is there a work around to make it work in FIREFOX? i.e. can I force a resize event to happen on a div in firefox or is there some other event I can trap when a user changes the browser font size?

here's my js code: topmenu is what I'm trying to trap the resize event from.

this code is loaded in the head of the page.

function maindiv(){
estartup=document.getElementById("startup");
econtain=document.getElementById("contain");
emain=document.getElementById("main");
etopmenu=document.getElementById("topmenu");
emaincontent=document.getElementById("maincontent");
nopx = document.childNodes ? 'px' : 0;
contw = document.body.clientWidth - 80;
conth = document.body.clientHeight - 80;
if (contw < 0) { contw = 0;}
if (conth < 0) { conth = 0;}
econtain.style.width = contw+nopx;
econtain.style.height = conth+nopx;
if (conth >= 100 + etopmenu.clientHeight) {
emain.style.height = (conth - etopmenu.clientHeight - 100 )+nopx;
}
if (contw >= 172) {
emaincontent.style.width = (contw - 172 )+nopx;
}
estartup.style.visibility = 'hidden'
}


function fsize() {
etm=document.getElementById("topmenu");
if (typeof window.addEventListener != 'undefined')
{
etm.addEventListener("resize", maindiv, false);
}
else if (typeof document.addEventListener != 'undefined')
{
etm.addEventListener("resize", maindiv, false);
}
else if (typeof window.attachEvent != 'undefined')
{
etm.attachEvent("onresize", maindiv);}
else
{
window.alert('Failed to attach an Event Listener

Please Report');
}
}

if (typeof window.addEventListener != 'undefined')
{
window.addEventListener("load", maindiv, false);
window.addEventListener("load", fsize, false);
window.addEventListener("resize", maindiv, false);
}
else if (typeof document.addEventListener != 'undefined')
{
document.addEventListener("load", maindiv, false);
document.addEventListener("load", fsize, false);
document.addEventListener("resize", maindiv, false);
}
else if (typeof window.attachEvent != 'undefined')
{
window.attachEvent("onload", maindiv);
window.attachEvent("onload", fsize);
window.attachEvent("onresize", maindiv);
}
else
{
window.alert('Failed to attach an Event Listener

Please Report');
}

Any clues?

Simple Browser Detect

Jul 20, 2005

I've seen plenty of browser detection scripts but they all seem to be slightly different and don't really fit my needs. I have various places where if the browser is IE I'd like to display [this html code] else [display this]. For example, if a browser is IE I want to use this CSS file
otherwise use a different one and if it's IE make this cell x pixels high else make it y pixels high. I'm sure this is easy ....

How To Detect Specific Browser And Then Redirect

Dec 4, 2006

Basically, I need a browser detection script that will detect what version of what browser the user is reading. My site works with IE 5.5SP2 and up, Netscape 7.2 and up, Opera 7.1 and up, and Firefox 1.0 and up (have not tested on any Mac browsers).

What I want the script to do is once it's detected a version of one of these browsers or higher, to continue loading the page. If it detects a lower version, or any other browser, I want it to direct users to a page telling them they are using an old or untested browser, where I have links to update the tested browsers and a link to continue to the site anyways

I have tried a couple scripts, but they only partially work. The one below seems to work so far for the two browsers I can test on (It goes to the good page for IE 6 and the bad page for NS 4.79 (I added Firefox and Opera myself, so I don't know if it works).

browser = navigator.appName
ver = navigator.appVersion
version = ver.substring(0,1)
if (browser=="Internet Explorer") {
if (version<="5.5")
document.location.href="index2.html"
}
if (browser=="Netscape") {
if (version<="7.2")
document.location.href="index2.html"
}
if (browser=="Firefox") {
if (version<="1.0")
document.location.href="index2.html"
}
if (browser=="Opera") {
if (version<="7.1")
document.location.href="index2.html"
}

How do I specify that IE 5.5 has to be 5.5 SP2? And how do I specify that every other browser in the universe except those lined out above in the code has to go to index2.html? I don't know how to specify that Safari has to go to index2.html while Netscape 8 doesn't.

Detect Browser Process Termination?

Oct 24, 2009

I am a newbee to JavaScript was was just fiddling around with events for a browser... Is it possible to detect the browser process termination done through the Task Manager in windows. Process:

1. Goto Task Manager
2. Right click on the browser process e.g. iexplorer.exe
3. Select "end process" to terminate the process

JavaScript can detect the window close by using body onunload event. On the similar bases, is it possible to detect the process termination event using JavaScript?? I tried a simple example using body onunload, but it failed to run the onunload event during the browser process termination. And i am of the opinion that this is not possible as all using JavaScript since terminating a process is a system / OS level task and is not related to browser events.
