Working With Element.style Attributes
Nov 1, 2005
I'm developing a web-template editor for a client, and they want it to update the changes in real-time using javascript. So, in other words, when a person selects a different background image, I use:
document.body.style.backgroundImage="url("+bgimg+")";
Well, I've run into a little problem. I can't seem to find any manual on what comes after style.*
So far, I've seen style.color, style.backgroundImage, style.backgroundRepeat, style.backgroundColor. But, I'm looking for something that can control text-decoration, font-weight and a:hover
Does anyone no where I can find a list of all properties support after style.*?

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?

In this line of code:
<div style="display:none;color:green;"></div>

<html>
<head>
<script type=text/javascript src=/scripts/jquery-1.3.2.min.js></

given a cell from a table...
function Tbl_GetCell(tbl, row, col)
{
var theRow = tbl.getElementsByTagName("tr")[row];
return theRow.getElementsByTagName("td")[col];
}
I can set attributes like width, height, and align, but how can I set cell style info?
cell = GetCell(tbl,row,col)
these work fine... cell.align = "center"; cell.height = 22;
but this doesn't... cell.style = "font-weight: bold; text-decoration: blink"

I'm having trouble with some flash players that don't abide by the style attribute of the div they're created in using Javascript. When the flash-players' source is hard-coded into the page source they render fine, but the more players, the more bloat as you can see in the source of the original page.
Example:
[URL]
Original Page with old code:
[URL]
The problem code:
<script type="text/javascript">
function clv(obj){
var strst="[URL]";
var strnm=obj; .....

I assume you know about this code:
Code:
document.body.style.background = "url() fixed #000000";
where you can change all of the page's background attributes..I was wondering if there was a similar one for font so that I can change the face, size, and color of all font on the page at once (when the page loads)I want this code in javascript because I want the font style and the background color in my page generated instead of fixed

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
<html>
<head>
<title>expandable text area</title>
<style type="text/css">

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'm creating an img element and appending it where needed. Is it better to set the new img element attributes like this:
var imgEl = document.createElement('img');
imgEl.src = "images/cal.jpg";
imgEl.width = "16";
[code]...
or should I be using imgEl.setAttribute('src', 'images/cal.jpg');

var fdot;
fdot[0]=new Image();
fdot[0].src="images/5dot0.jpg";
fdot[1]=new Image();
fdot[1].src="images/5dot1.jpg";
fdot[2]=new Image();
fdot[2].src="images/5dot2.jpg";
fdot[3]=new Image();
fdot[3].src="images/5dot3.jpg";
fdot[4]=new Image();
fdot[4].src="images/5dot4.jpg";
fdot[5]=new Image();
fdot[5].src="images/5dot5.jpg";
function overlay(e,num) {
var targ;
if (!e) var e = window.event;
if (e.target) targ = e.target;
else if (e.srcElement) targ = e.srcElement;
if (targ.nodeType == 3) // defeat Safari bug
targ = targ.parentNode;
targ.src = fdot[num].src;}
Overlay is called as an onmouseover event from an image's map AREA tag, sending event and a number. FF's JS Console spits out that fdot has no properties. Ideas? Better ways to do this effect (replace the image depending on which area of the imagemap is mousover'd)?

I need a function that can return any elements attributes when clicked.
Mostly this is for getting link data. But there are a few elements in the Google Maps javascript api that I don't know what type of element they are.
Once I am able to get any clicked elements attributes, I will execute the data in ajax to log the data in my database. Once I have an idea of what needs to be and doesn't need to be tracked, I will apply filters accordingly.

When you need for a certain element (say a text input box) to remember some data, what is the best way to do this? Can you extend the input box object with jquery? Right now i've been storing it in the rel tag $('#testInput').attr('rel','extrainfo') it just seems like there should be a better way to do this.

I have a JavaScript file which Adds and Removes elements when you click a button.
Adding stuff is okay, but removing elements is more complicated.
When you add an element you also add id=x. Each time you add an element x goes up one. For example if I click "add element" 5 times it would be like this:
HTML Code:
If I wanted to remove the thrid element then I would want the following divs to replace it, for example it should look like this:
HTML Code:
I can't figure out how to do this, here is what I tried but it won't work

Code:
test.div.style.backgroundImage=test.div2.style.backgroundImage;
It works if I specify the actual background image within the function, so I know the image is there, and I know it's been properly assigned to div2, but div1's background image doesn't change.

I have a huge form with a lot of data.
There is a table that data in it I need to display on a print screen (of course this data isn't being displayed in the regular table).
So, I put the display text in a span tag.
So, this is how each item will look:
I need a way to grab all spans on the page that have the attributte of "printData" and grab that text inside that attribute and print it out.

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');

I have a element that uses a class, like:
<style id="abc" class="myClass" onClick="test(id)">....</span>
The function:
function test(id) {
alert(document.getElementById(id).style.backgroundColor);
}
Why doesn't this work? It returns nothing, but the class, which the element uses, has a background-color value set... ?!?!?! Am i missing something... ?

I am working on a little javascript project, and I need to get an arbitrary element's style information.
For instance, I want a method that you can pass a reference to an object, and for instance, find the current css height property that applies to it, no matter where it was declared. I don't mind it returning a null value if it wasn't set anywhere, but if it's coming from some css class or some css id or some locally defined style, I want to know what is being expressed.
If I just try el.style.height, it only lets you know what the height is if it was explicitly defined in the style tag.

i am trying to have text-decoration applied on some text depending on the value of certain variable. If the value of myvar=0 text-deco =none and if it's 1 then text deco= line-trough...
Kind of the same thing that emails web apps like yahoo or gmail do with mails read or unread if it's unread then email title/subject is bold/strong but if it's read then email title is in normal font-weight...
here is some piece of code i have written to do that
the text on which i want to apply the conditionnal decoration is a table cell (cell2DisplayCell1), the text itself is inserted by the innerHTML instruction!
I tried to introduce the conditional statement with a function displaylinksLineThrough() which is defined in the second block code... Code:

I have the following css rule that describes the style of an element with an id named as treeList:
#treeList{
color: #ffee00;
width: 100%
}
Now I need jQuery to add this rule to another element with, of course, different id such as #fgsf:
<div id="fgsf">
//some text
</div>
Could jQuery able to apply the style rule of #treeList the other id element fgsf?

Any way to remove styling on a parent element with JS (as it can't be done in CSS). In a situation like this:
Code:
<p><img src="image1.gif"></p>
<p>Brutus aderat forti.</p>
<p><img src="image2.gif"></p>
<p>Caesar adsum jam.</p>
The <p> element has default padding, but I'd like to remove the padding when the <p> contains an image. This was my failed attempt to target the <p> element:
Code:
window.onload = paraPad;
function paraPad() {
var img = document.getElementsByTagName("img");
var imgpara = img.parentNode;
for (i=0; i<imgpara.length; i++) {
imgpara.style.padding = "0";
}}
