Forcing New Element's Height?
Dec 7, 2011
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?

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

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".

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:

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.

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’}

I'm doing some work on a theme and I'm using horizontal accordion scrollers.
You can see on my practice page that the three main sections (on the right) are all different sizes. The rightmost section has a big block of text but it is all cut off after 600px (which is what I have it set as).
Since this will be for a blog there will be different sized pages with every click but I can't seem to find a way to have the elements default the height based on the amount of content.
The accordion script uses MooTools and you can see everything I've done on my development page.

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%'.

I have the following DIV, that I need to position in the center of the page, I have the following code, but you can see the div is not exactly center, space I have from the top is not the same I have in the bottom, the space I have from bot side is the same.I was wandering also if I can do this dynamically, meaning the div will receive the width and height in run time, and them I will send the values to my method "centerObj" (How I can get the height and width of the div element.

<head>
<script>[code]....

I'm having an issue getting the height and width of DIV elements that have resized themselves to fit their content.
Note: I do not have a problem getting the height and width of DIV elements that I have set using Javascript. The probel is that this value appears to stick. I.e. the height is set to 150px, then the content is changed and the DIV cosumes as much height as is required (clearly more than 150px), however analysing the DOM indicates that the height is the same (though it is clearly not).
I want to know how to get hold of the 'actual' size of a DIV element that is manipulated by the content of the DIV.
I am also interested in a solution that works in IE and Firefox (at least).

I'm writing a script that proactively validates data input.
Under IE, throwing up an alert seems to interfere with the behavior of
radio buttons. In other words, if changing the value of the radio button
field fires the validation, the radio button either isn't set or isn't
displayed correctly after the popup is dismissed.
If I stick the error messages in a non-editable textarea field, the
textarea field doesn't get refreshed.
I tried "focus" - didn't help.
Mozilla works perfectly of course.

does anyone know of a way of forcing the onChange() event of a control (it happens to be a <SELECT> if that is relevant) to fire off? (That is apart from the obvious one of changing the value with the mouse / keyboard!!!!)
I have some code which alters the currently selected element in a list and I need the list's onChange to then be fired off. The code is designed to work with many different lists, so I can't hard-code the same functionality into my code that is normally provided by the onChange.
I've tried ....element.onChange() and .....element.Change() but neither of these seem to work.

I know, frames are yucky but for now this site uses them. Problem is this, the search engines are great at putting this site in the first 2 pages but it is the page that goes in the main frame and without the frames there is no navigation. To make a long story short I used the JavaScript that I found at http://www.webreference.com/js/tips/000405.html that shows me how to force the frames to appear.
My problem is this:
When I try to implement this code on files that are in subdirectories, and there is a ton of them, it doesn't work. What it ends up doing is showing the URL like this:

I'm the Webmaster/Designer for a Private Sector Company Intranet.
Now without exaggeration we must have the most IT-apathetic staff in the world even though they all work on PCs every day!
Anyways I've been trying to get them to bookmark the Company Intranet Site as their homepage for months to no avail.
I've sent them regular emails on the importance of doing it, run articles in the Company magazine, even put a JavaScript (make this your homepage) button on the site and nothing works. I would guess that even now only maybe 20% have it as their homepage.
Bits and pieces get posted to the Intranet Site all the time and once a month I post a Team Brief which contains a lot of very pertinent and important information for the staff.
I'd like a JavaScript that I can inconspicuously force a homepage. In other words I'll link to the Intranet Site from my email and by simply clicking on this link the user will have unwittingly booked the Intranet as their homepage.
Obviously smething that will not flag up a User "Do you accept?" permission.

When the user resizes the browser (either by clicking on the lower right or clicking the button at the upper left to maximize screen dimensions or not), how do I catch that event and then automatically issue a browser refresh? Ideally, this solution should work for both IE and Firefox.

I have what I think is a fairly simple problem, but I cannot figure
this out. I have a SELECT object on my page. When the user performs
a certain action, I want the focus to be placed in the drop-down field
AND the actual list of drop-down objects to appear (i.e. simulating
that the user has clicked in that field). Ideally, of course, the
currently selected entry should be highlighted. Listed below is a
snippet of sample code. If the focus is currently in the text field
and the user clicks on the "Test" button, I would like the entire
drop-down menu to appear. I have not had any success with the
"fireEvent" method or the "click" method (only "focus" seems to work). Code:

Is it possible to force an entry into the browsers history without actually changing pages? I want to change the history based on a tabbed interface so that when linking away from one of the tabs a back button will return me to the correct tab or even the browser back button for that matter.

I have a JS Script which keeps pretty much a persistent connection open using AJAX, which I use for instant notifications (it scans the table for a change and then returns it when there is one) this bit works perfectly But because the connection is persistent, i cant click the refresh button or any other non ajax links until the notification returns a value is there anyway to kill all the javascript threads running the background when the browser wants to reload a page or navigate to a new one?

I know you can use JS to prevent other sites from using your .html in a
frame / frameset.
Can the opposite be done ?
If your page is designed to be viewed inside a Frame / FS only;
and your page is requested, can you redirect to the Frame page, as intended ?

When the user visits a page, an iframe will be displayed. What is the best way to force the user to click something in this iframe? I suppose I could do that thing where the mouse always has a part of a div "glued" to it, so wherever they click, the certain area is clicked. But, then they could just hit the back button.

I have a snippet of code that's very straight forward. It copies the values of four form fields into another set of form fields (e.g. a billing address to a shipping address). That part works fine, but what I need to have happen is the form fields receiving the data needs to fire their onchange events. They don't do that after the values are changes programmatically. I've tried firing it manually using the onchange() method (as shown below) but that only gives me an error:
$("shipping_address").onchange is not a function
/scripts/registration.js
Line 32
how I can get that onchange event to fire?
Code:
function copyBillingAddress() {
$('shipping_address').value = $F('billing_address').strip();
$('shipping_city').value = $F('billing_city').strip();
[Code]....

I am submitting a form via AJAX. The form may either return HTML (when there are input errors) or JSON (successful response). If during request I specify "dataType: 'json'" then HTML doesn't get thru correctly, if I don't then JSON is displayed as plain text. I am sending the "application/json" header back correctly. I don't understand why doesn't jQuery just pick that up and parse it as JSON? Is there an option? Is there something I can do to make this work?
