Accessing <area> Attributes In Mozilla?
Jul 20, 2005
I would like to be able to dynamically change the attributes of an <area>
element in an image map. The following works in IE 6 and Opera 7:
<map name="Map1">
<area shape="rect" coords="10,10,100,50" href="foo.html" id="area1">
</map>
....
<script>
document.area1.href = "bar.html";
</script>
but it doesn't work in Mozilla 1.4. I tried using name="area1", but that
didn't work either. Is there any way to referrence the attributes of an
<area> tag in Mozilla?

I'm having an issue with CSS, JS and the DOM. It's gonna drive me batty. I
am trying to access the properties of a layer in JS which have been
initially set in an external CSS. The problem is that for some reason JS
isn't receiving NULL for all the properties of the layer. For instance:
HTML
<div id="blarg">.....</div>
JS
var t = document.getElementById("blarg").style.left;
CSS
#blarg{
position: absolute;
left: 200px;
}
t == NULL and I can't figure out why. It is this way for any CSS attribute
I attempt to read (width, positional, the whole kit and caboodle).
It does work if I set the attribute in JS before I read it.
JS
document.getElementById("blarg").style.left = 30;
var t = document.getElementById("blarg").style.left;
t now == 30. The only thing I can think of to explain this is that when
the document gets loaded my layers aren't getting their attributes filled
out. The object gets created and the attribute fields are blank until I
fill them in. Thusly my creation of CSS's was a waste of time. Grr...
Any ideas/suggestions? Google has been of no help. :-( This is occurring in
IE 6, and the gecko engine browsers.

This is probably a ridiculously simple task, but I am new to Javascript, so here goes. Is it possible to get the 'id' (and other attributes) of a 'div' area after I have clicked into it?

I am relatively new to javascript and am working on a script where I
want to utilizes a couple of iframes and format text in them. I have
run into a problem with getting the following code to work in mozilla.
It seems to work in ie.
Eventually I will be replacing the H1 node with a table until I can get
the H1 node to show up in mozilla there is not much point.
I have tested using both a javascript created iframe and one built in
the html file. In both cases the iframes have an id of something_ifr...

I am have an MVC app that generates a list of rows, of which one of the columns is a button. Here is the rendered HTML for the buttons:
<input
id
="btnUpdate21"
type
="submit"
value
="Approve"
synchId
="21"
/>
<input
id
="btnUpdate22"
type
="submit"
value
="Approve"
synchId
="22"
/> .....
Following is my selector that I use to bind the buttons to my click event:
<script
type
="text/javascript"
charset
="utf-8"
>
$(document).ready(function
() {
$('input[id^="btnUpdate"]'
).click(promptForSynchDate);
});
I have been trying to access the button Id, though what I really need is the attribute synchId, to use inside of a modal. I have so far been unable to access either one of them. My modal works fine. But the value of either attribute is always "undefined".
Here is my click event handler: (I stuck the alert in there just for debug purposes)
function promptForSynchDate() {
$(document).ready(
function () {
var test1 = $(this).attr('id');
alert(
'test1 is : ' + test1);
$(
'#approve-synch').dialog({ .....

had this in browsers areas but people told me I should put it here in Javascript because more people here would probably have seen it before and know why it happens. I have basic Javascript that rotates images. I've noticed any kind of Javascript code that rotates images has this same problem only in Mozilla. When the images rotate in Mozilla in between the rotations, Mozilla browser adds a little colored square that represents a blank image that are able to be seen does anyone know why Mozilla Browser adds that? For example when looking at this page in Mozilla can see it. if you know if this is some Mozilla problem with Javascript and images. Doesn't happen with IE and other browsers shows the images only and nothing else.

1. When I have the "<textarea>" code lines in it put a text-area on the page, but it puts all of the code following that first text-area line into the text-area box and doesn't execute that segment of code.
2. When there is no "<textarea>" (for the sake of seeing if the rest of it worked) it doesn't check the survey.
I'm stumped and can't figure out what to do at this point Code and pictures follow:

I'm using a jquery plugin called jplayer. I need to "bookmark" the current track.
The only way to know the current file playing is to look at the div called jplayer_playlist_current.
<li class="jplayer_playlist_current">
<a href="#" id="jplayer_playlist_item_1" class="jplayer_playlist_current">Introduction and guidance on usage</a></li>
What I want to get from it is the id, ie: jplayer_playlist_item_1
I thought that this might cover it:

But nothing I do, no amount of googling or plugins, is getting me this result.

I want to move a div around a page, and I do this by getting the original top and left values of a div, and then change them. But the problem is getting the original values; I checked online and thought that this would work:
var chart = document.getElementById(charDiv).style.top;
var charl = document.getElementById(charDiv).style.left;
alert('char_t:' + chart + ' char_l:' + charl + 'charDiv:' + charDiv);
charDiv is passed into the function (its the id of the div I want to move). I know that charDiv has a value by looking at the values of the alert() statement, but the values of chart and charl are empty. The alert simply outputs char_t: char_l: charDiv: charOne

I attempting to set attributes for all tags of a particular type....
I have a bunch of thumbnails <img> tags; when I wand over them I would like to show the corresponding large image with a script but the tags require onMouseOver events. I really don't feel like adding a bunch of onMouseOver="myShowScript" attributes to every img tag manually...
my scripts aren't working. I'm sure there is some fundamental concept about java and html I don't get...
here's ONE of the versions that doesn't work.. I've tried a few things but I'm open to scrapping everything for a better way...
function addAtts(){
var numberOf = document.getElementsByTagName("img");
for(i = 0; i < numberOf.length; i++){
numberOf[i].onMouseOver="myShowScript()";
}
}

I have an application where a user can create a newsletter with a
contenteditable div box and submit it to a database. The problem occurs
when the user tries to edit their newsletter. The edit page looks
exactly like the create page only their already created newsletter is
supposed to appear in the contenteditable div box. To do this I
retrieve the information from the database in the server side. Then I
have the following client side script.
window.onload=doInit
function doInit() {
var content = "<%=sContent%>";
div.innerHTML = content;
}
This seems to work in all cases except if the HTML to be displayed
contains any style attributes. For example, if any of the text has
background color then the HTML code will have the tag <font
style="bacground-color: #000000"> and this will cause nothing to appear
in the div box. Has anyone run into this problem or know how to fix it?

I have a web form with several "submit" buttons.
One of these uploads a file, and I want to validate the user input
prior to submitting the form. I have an event handler specified with
the form's "onsubmit" attribute which checks the the
event.target.value to make sure the right submission type is being
evaluated.
When I try to get the target or srcElement value from the event
object, however, it is always "undefined".
Here is the cut-down version of the handler...
function validateIfUpload() {
if (window.event) {
evt = window.event
} else if (document.event) {
evt = document.event
}
if (evt.target) targ = evt.target
else if (evt.srcElement) targ = evt.srcElement
if (targ.nodeType == 3) // defeat Safari bug
targ = targ.parentNode
if (targ.value == "Upload") {
return validateUpload('prod_img_f')
}
return true
}

While trying out some of the code given in the book, I found that passing CSS properties and values in the jQuery is not working somehow. Following is what I have written.
$(document).ready(function() {
$('#first tbody tr:even').css('background-color': '#dddddd',
'color': '#666666',
'font-size': '11pt',
'line-height': '2.5em');
});
Where as if Ipass CSS properties infollowing way, it is working. But I would need to write multiple statements for that. $('#first tbody tr:even').css('color', '#873450');

If I have the following hyperlink :
<p><a href='page.htm' id='foo' class='bar' alt='alt text'>click</a></p>
I know that I can get (eg) the href attribute via $('a').attr('href') BUT I would like to do the following :
get *all* the attribute names and values without knowing anything about the attribute names and values in advance (or even how many there are) - something like a loop and $('a').(attribute name, attribute value). I suppose they would best be placed in a JavaScript object as a set of name/value pairs eg { href: 'page.htm', id: 'foo', alt: 'alt text' }

I need to be able to get the css attributes that a particular class defines. Such that if I have a class called "SomeClass" I want to see if it defines the attribute "position". I've tried using .css on an element that has the class, but of course that picks up the defaults and any inheritance.
