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%'.
Trying to get the height of an element whose height is specified in the CSS.
So I am trying to animate the height of an item, where I have: <img id="myButton" src="myimage.jpg" /> <div id="myDiv" style="height:50px;overflow:hidden"> asdklf
[Code]....
However, it only registers as 50, even if the element is 500
If I didn't set the height of an html element on a web page with html attributes. Then obj.style.height always reports "0" even after the page has completely rendered. Is there any way to get the actual height after being rendered?
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">
I have a list of images on my website, and I because of different resolutions on viewers screens, the total height of the div changes. I need to set the "top" value as the height of ".photoswrap".
when I try to get the height or any other graphic property of an element which is hidden (in my case, hidden in one jQuery UI tab), I can't manage to get the height of the element. If I do: $("#my_element").outerHeight() I get zero. Whereas If I do the same when the element is visible, I get its height. I work with jQuery 1.3.2 and FF 3.5.
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 am attempting to change the style after the user has loaded the page(every x number of seconds) but the element just doesn't seem to berefreshing. I have done all of the checking, and it seems like it ischanging it but it isn't showing that on the page.
$('.viewBookBtn').click(function() { $(this).parent().parent().find('.hideable').toggle( // just the toggle function works fine function(){ $(this).css('visibility', 'visible'); // but when defined it doesn't target the hideable classed element }, function(){ $(this).css('visibility', 'hidden'); });});
I have 2 divs . The top blue one is of 30 px height, te bottom should stretch to 100 % -30 px. Can this be done somehow crossbrowser ? is there a way to do 100% -30 px ?
On the right site there is a box with a vertical scrollbar. It´s a DIV (id="right") with an iframe in it. Maybe I´ll put a DIV with overflow:auto in it but it doesn´t matter now.
The customer wants that this 'scrollbox' takes all available vertical space. That means it should start right under the header and end above the footer. But when there is much content and the user scrolls down the page the scrollbox has to stick under the top edge of the viewport.
Does anybody know how to realise this?
I think I can use JavaScript to get the y-position of the scrollbox and then change margin-top of the iframe or padding-bottom of DIV id="right" or whatever. Code:
I'm pretty new in JavaScript, so forgive me if that's a lammer question.Here it is: I had wrote some JavaScript to dynamically resize div elements on the client side. In fact the code works fine, but when resizing multiple (nested) divs in a roll not all of them gets resized. The reason is that the new size of the parrent element is not applyed yet when the script gets started for a child!
So my question is: Is there a way (method) to force new size of the parent before i call my script for the nex element? How can I solve this?
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:
How can I change the height and width of an element with Javascript? I have tried and so far I can only change either the width or height but not both, doing something like this…
Code:
<HTML> <HEAD> <script type = "text/javascript"> function changeSize(){document.getElementById('test').style.height = '200'}
[code]....
And this works fine but if I try to change both height and width it doesn’t work. Doing something like this doesn’t work
Code:
function changeSize(){document.getElementById('test').style.height = '200' width=’200’}
