I'm doing some what if R&D and have a question. Is there a way using JavaScript to detect what the status is of a particular style instruction for a specific tag? For example how could I detect the current display (e.g. Hidden, inline, block, etc) status of the following tag?
<div id="mytag">bla</div>
How do I check the status of a style? I thought something like this would work, but no joy:divTest = document.getElementById('link_container'); if (document.divTest.style.display == "none") {}
View 2 Replies View RelatedMy understanding had been that $.css("width") would return the original user selected style, eg "100%" or "10em", and $.width() returned the computed width, always in "px". Not so, following the code through for .css(), it calls something called getComputedStyle and the only difference between the two functions turns out to be a post-fix of "px" on the .css() result - not very useful. I need to know whether my user has called me with a proportional dimension, or a fixed one. How to tell with jQuery?

Is there a way to hide the code between it?
This is probably quite a simple problem but I can't figure out the answer. I'm working on a site that has news stories and events coming in. What I would like is to have the news stories to be styled with squares and events with discs for instance. I might be able to change the actual plug-in so the CSS affects this change, but I just wondered how I could change the list-style-type with jQuery.

if I have an html page that uses the <style> or a <link> to call a style sheet these properties aren't available to JavaScript is there a good way to access them? eg

<style type="text/css">

I'm trying to use JS to move the cursor from my user login text field
to the password text field - I've put the onKeyPress() event in the
user input tag but then I press the Tab key the cursor doesn't move -
function detect_tab_key()
{
var key_code = window.event.keyCode;
if (key_code == 9)
{
document.forms[0].frm_password.focus();
document.forms[0].frm_password.select();
}
}
I would to change the color of some td cells if there is text in it. Right now this code does the job, but it changes the color of evry table. I'd like to know a way to do this on one table in my page and not all of them.
var count='0';
var TDs=document.getElementsByTagName('td')
var length=TDs.length;
i='0';

example: onkeypress="return eventHandlerFunction(event)"
Why is it that you need the return keyword?
Where does the argument event come from?
I know it works, I just want to know why it works.
I've been looking at some refferences and can't seem to find an answer if someone could give me an explanation or point me to a website, that would be great.
I am trying to do something I thought would be simple in javascript, and I'm at a loss. First code is GOOD code, except that it does not account for the possibility that the button(s) in question do NOT exist. The second and third subsets are two of several attempts to do just that. Code:

I can do this no problem with javascript - except for the detecting flash part. I have no idea how to have a js detect flash - or even if its possible.

I have a dynamic web page with three vertical divs.
In the style attribute, I do not specify the div height because I don't know that until they're draw by the browser.
However, I'd like to add a fouth horizontal div acfross the bottom of the page at the bottom of the tallest of the vertical divs.
Is there any way to get the height of a div after it's drawn?
I know in the new browsers you're not able to change the value of the status bar. Which is fair enough, i understand why and agree.
Although, i cant seem to get the value of the status bar. One used to be able to do window.status.
But that doesnt seem to work Wondered if someone could point me in the right direction.
I have the code below, and I want to know where and how do I make a status window appear on the pop-up window it generates:
<script type="text/javascript" language="JavaScript">
// Centered Pop-Up Window (v1.0)
// (C) 2002 www.smileycat.com
// Free for all users, but leave in this header
var win = null;
function newWindow(mypage,myname,w,h,features) {
var winl = (screen.width-w)/2;
var wint = (screen.height-h)/2;
if (winl < 0) winl = 0;
if (wint < 0) wint = 0;
var settings = 'height=' + h + ','
settings += 'width=' + w + ','
settings += 'top=' + wint + ','
settings += 'left=' + winl + ','
settings += features;
win = window.open(mypage,myname,settings);
win.window.focus();
}
</script>
If I detect an empty textbox, I fill it with a value ('Dad'). If I do this twice, the second time around IE 6 fails to notice that I've cleared the textbox again, thus leaving the textbox cleared. Is there a recommended workaround? Opera 7.23 is detecting the second deletion fine.

I am trying to detect whether a user entered text in a textarea
or hit the delete/backspace button (thus, erasing something). Once
that is detected, I would like to set "var bSaveRequired = true;". It
would be great if this function worked cross-browser -- IE 6.0 and
Firefox.
Say I'm on the site www.xyz.com and on a certain page if the user leaves the domain xyz.com, I have a popup cme up w/ stuff. I don't need to know what the new domain is, I just want to know if the user left / is leaving xyz.com.
View 1 Replies View RelatedI'm trying to determine if the user clicks the
stop button during a post send, basically. Specifically, if a user is
uploading a file to my server, and they click stop at some point, I
need to be able to tell the server that stop was clicked, so it doesn't
think that's the whole file. I've noticed that an error message is
written to the Apache log, but that seems like a strange way to keep
track of user-interrupted events. (Note: this is Apache/mod_perl
server-side)
I guess what I'm thinking now is that JavaScript detects the stop
(since it is client-side), then sends a message to the server that an
error occurred, or something. Like I said, the onstop event is not
doing what I'm expecting, and Firefox doesn't like it anyway, not to
metion the other browsers out there. So my question is what's the
"idiom" or "standard way" of detecting this sort of situation. I'm
quite certain I'm not the first one to need it.
If I want to detect a user's language, so that I can
change some text to suit them, how do I do that in
Javascript?
Or aren't modern browsers supposed to be able
to cope with more than one language on a page,
separated somehow by language identifiers,
and display only the appropriate text? Maybe
I was dreaming when I read that.
I'd like to be able to detect when page content is dynamically changed
by Javascript. I'd like to detect any changes to the content, such as
the addition of new DOM elements and when DOM elements that are hidden
are made visible (or vice versa). I will have no advance knowledge of
the scripts that will be run along with the script I will create.
I've implemented a solution that works reasonably well, but I'm not
sure if there are cases I'm not thinking of where it will fail, or if
there are more efficient means of doing the same thing.
My solution is to simply retrieve and periodically compare the content
of the innerHTML property of the main body tag elemnt.
So, summarized as follows:
function check() {
var bodyContent = document.getElementsByTagName('body')[0];
if(bodyContent != oldBodyContent) {
alert('body changed');
}
setTimeout(check, 500);
}
Is there a better way? What won't this catch?
I am writing a script that uses xmlhttp.open, when i attempt to open a protected page I get the login prompt for my htpasswd. Is it possible to detect if there is a login requirement before the login prompt and if there is a login just do something else? I can use xmlhttp.status and check for 200 but if I do this then it would happen after the login prompt.
View 1 Replies View RelatedI'm making an Intranet site for someone who is not very familiar wit
making websites, thus I would like to make it as simple as possible fo
her when she needs to update it.
The intranet site uses frames - one menu frame that is always present
and one frame into which the content is loaded. The intranet sit
features many, many links to both internal and external pages - i
internal pages within the intranet and external pages on the interne
(http://)
What I would like to do is make it so that if a link is internal, th
content will load into the content frame and the menu frame will remai
at the side, but if the link is external, it will load the target int
the entire browser window. Using HTML, this would simply be a matter o
stating the href and then target="content_frame" for internal pages o
target="_top" for external pages.
But, like I said, I am making this site for someone who is not familia
with linking targets and even if I told her to define the targe
whenever she makes a link, she'd probably forget or get confused an
then wonder why external pages are loading with the intranet menu fram
still present or why intranet pages are loading with no menu at th
side!
While I have good experience with HTML, I am fairly new to JavaScript
which is why I am here asking for help.
I understand that Javascript can detect the protocol of a link,
believe you would use "link.protocol". In basic terms, what I woul
like to do is:
if link.protocol = "http://" then target="_top" els
target="content_frame"
But since I'm not familiar with the precise way of coding JavaScript,
would just like some help with transforming this into correc
JavaScript code so that it will work.
I've written a script that displays tooltips when your mouse hovers over a link - all this is fine, but when I click on the link and move to another page, then click the back button on the browser to go back, the tooltip for the link I clicked is still visible! It'd be great if there was a way of detecting the button had been pressed so that I can hide it...
p.s. I tried onclick = "tooltips.hideToolTip(4); return true;" for the links but no joy...
