How To Remove Style From Parent Element

Dec 10, 2009

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";
}}

JQuery :: Element Overflows Containing Block When Parent Border/padding Change - Not When Parent's Margin Changes

Sep 24, 2011

Demonstration page: [url]

Adjust the CSS margins of the BODY element with the first slider. The yellow P (paragraph) element resizes to fit its smaller containing block, as I would expect.

Then, adjust the CSS border or padding of the BODY element with the second and third sliders. The P element does not resize, though its origin changes. Instead, it overflows its containing block.

Finally, adjust the margins again. The P element snaps back into its containing block.

As you can see from the source, this is jQuery 1.6.4 and jQueryUI 1.8 pulled from googleapis.com.

Edit: Client is Google Chrome16.0.889.0 dev-m.

How To Remove A Border Style Under IE?

Dec 8, 2006

I have the following problem:

An input field get a border assigned by a style class (e.g. 2px solid red).
When the field gets the focus, we set the border to green.

element.style.border = "2px solid green";

When the field looses the focus, the border should change back to red.
We just want to remove the style we have set, when the field has got the
focus, so that the style class is visible again.

element.style.border = "";

Under Firefox that works but not under IE.
We have changed to the class mode, because we don't want to save the
previous setting and restore it later.

Is there a possibility to remove the style (especially the border style)
under IE, so that the style of the assigned class is visible again?

element.style.removeAttribute doesn't seem to work, but may be I make
something wrong? Code:

[FireFox] Parent Object For Style In Setter

Mar 9, 2006

this is my code:

CSSStyleDeclaration.prototype.__defineSetter__('di splay',
displaySetter);

function displaySetter(value) {
var parent = findParent(document, this);
if (parent) {
if (parent.tagName == 'TD'
&& value.toLowerCase() == 'inline' ) {
value = 'table-cell'
}
}
this.setProperty('display', value , 'important');
}


function findParent(obj, style) {
var nodes = obj.childNodes;
if (obj.style == style) {
return obj;
}
for(var i = 0; i < nodes.length; i++) {
var suBsearchResult = findParent(nodes[i], style);
if (suBsearchResult) {
return suBsearchResult;
}
}
return false;
}

As you can see each time I need to scan whole document for parent which I would like to avoid. Is there any other way to get an object on which style is applied to?

JQuery :: Tables With Toggle - How To Style Parent Row

Mar 9, 2010

I've successfully set up a table with toggling rows and alternate colour, and everything is working decently. Now, I've tried to do a further step by trying to style the parent row who do have child differently from those who don't, so that the user immediatly knows where clicking will bring result and where not. How can I do it? I've tried with the : parent selector but nothing, still keep looking all the same.

Here's my starting code:
<script type="text/javascript" src="../catalogo/js/jquery.js"></script>
<script type="text/javascript">
$(function() {
$('.parent')
.css("cursor","pointer")
.attr("title","Click to see")
.click(function(){
$(this).siblings('.child-'+this.id).toggle();
});
$('tr[@class^=child-]').hide();
});
</script>
<script type="text/javascript" src="../catalogo/js/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function()
{ $(".parent:even").css("background-color", "#FFFFFF");
$(".parent:odd").css("background-color", "#F2F1ED");
$(".child:even").css("background-color", "#FFFFFF");
$(".child:odd").css("background-color", "#FAFAFA");
$("a").click(function(event){
$('.parent').unbind('click');
});
});
</script>

One more detail: I've got a dynamically generated table (from MySQL db) with more than 1000 rows.

Using Javascript To Apply One Element's Style To Another Element

Jul 27, 2007

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.

Flashplayers Created Do Not Obey Style Attributes Of Parent

Oct 26, 2009

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:

The problem code:

function clv(obj){

Getting An Element's Style Properties?

Jun 21, 2009

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:

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.*?

JQuery :: Getting Applyed Height Style For An Element?

Feb 4, 2010

I am looking for a way to determine is an element style was determined (thru css) or calculated.

So far I can t find the RightWay(tm) for doing this. $().height() returns the calculated height which is the same as $().css("height"). I have solved the problem under IE and Opera using DOM.currentStyle.height. But not on other browsers (e.g. gecko). To make clear, I want to know if the height css rule in action is something like: 100%, auto, inherit, 3em, 5pt, 100px.

$().height() returns the browser calculated value to px, even if the current set is '100%'.
