How do I restore CSS properties for a selected element? I want to change the background-color of a particular item on click, then restore the original CSS bgcolor from the stylesheet when it's clicked a 2nd time.
The item in question has a CSS class applied to it from the stylesheet.
I only get an error telling me "test has no properties"...
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<script language="javascript" type="text/javascript">
var test = document.getElementById("test");
var title = test.getAttribute("title");
alert(title);
</script>
</head>
<body>
<p id="test" title="test title">This is a test</p>
</body>

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.
Maybe a stupid question (I'm not so familiar with javascript), but:
I want to change background of a paragraph or list item on mouseover. The
following code works:
<p onMouseover="this.style.backgroundColor='yellow'"
onMouseout="this.style.backgroundColor='white'">ppppp</p>
Now I want to minimize the coding bij using a function. How do I do that?
I have a billion elements that all share the same class. I have another billion elements that all share another class. This cannot be changed. My objective is to use one element to trigger onclick a change in the others elements' css properties, that is each element is paired with another, producing a billion unique pairs. From hours of deciphering the cryptic documentation examples ive come up with the following, which doesnt work. Assume that im using "name=item#" in the element's tag to identify each pair.
One fundamental issue with this is that it will change the opacity of both elements in the pair were both elements to share a name,or it will only affect the element being clicked on if not, but i only want it to change the opacity of the element that isnt being clicked. Another issue is that there are instances where i may need to set a setTimeout on a css property, and ive not found any documentation on integrating javascript and jquery together within a function.So how do i get this function to accept input from one element and affect the css properties of the other? And what would a setTimeout look like if it were placed around the opacity property?
I have 1 form, and dozens of elements. In the select elements I use onchange="somefunc()". In this function I'd like to access and change the form element attributes (such as form.element.option[].value and form.element.option[].innerHTML).
Is there a way to access the element that has just changed (unsing onchange="somefunc()") by passing a "this.element" parameter to access the elements properties such as form.element.option[].value within the function?
On a page I display a link of search results which are hyperlinks, which all have the same URL get paramaters with different values (i.e. companyreport.aspx?....). I want to then click on a search result hyperlink and then generate a Div popup (this is called through a javascript call that is attached to each search result hyperlink's onClick property.
For the hyperlink that is clicked, I need to take its 'href' value and use it (reason for us is in a bit).
On the popped up Div element is a dropdown box and two buttons (accept / decline). Once the accept button is pressed, I want to then go to the page the selected hyperlink was pointing to by using the 'href' value I obtain from the clicked search hyperlink and to also append to this hyperlink the a new GET parameter and the value of the dropdown box.
I have got this to work currently but it seems quite mess, so was wondering if there is a better solution to this.
For the search results hyperlinks I have...
Code:
PromptRequestReason(this.href); return false;
this '' javascript method is....
Code:
function PromptRequestReason(hrefLocation)
{
lnkDERequestReason.href = hrefLocation;
popup('popUpDivReason');
}
then on the DIV popup I have the following link....
Code:
<a id="lnkDERequestReason" onclick="this.href = this.href + '&reason=' + document.getElementById('drpPortfolios').value">Select</a>
now this all works, but I really seem like I am taking the long way around when there could be something simple.
I am dynamically building a part of my HTML page by setting the innerHTML of a DIV element. Immediately after I do that I try to retrieve the clientHeight and clientWidth of the DIV element in order to determine what height and width the element actually ended up being. But I always get 0 as both the height and width. The contents of the DIV, i.e. the HTML code that I inserted into it via the innerHTML, does indeed get displayed on the page. But I suspect that the browser doesn't actually update the page until AFTER my JavaScript code has completed and "returns control" to the browser.
Does that make sense? Is there any way I can force the browser to update the page BEFORE my code completes its processing, so that I can properly retrieve the width and height of the element I just inserted into the page?
I know the atomic way to set style properties of a DOM element like
Is there any way to set multiple properties in the same time? I'd like to spare some cpu time...
I assume if I use framework like JQuery to set more style props at once that call will be interpreted to the atomic way I described above...
Am I right with this guess?
I have an object on the document element that allows for other components to register with it, i have a custom event something along$(document).bind("register",function(thechild)..So in the child object when they are created i call$(document).trigger("register",this);And indeed i get the DOM object. However i'm looking for the plug in object, i want to be able to call methods on the passed childobject and access it's Config.Does that make sense? How can i write a plug in that is applied to various objects that also registers itself with an 'overseer' object on the document element in such a way that i can allow that overseer object to call methods on any registered child objects?

I have written a script that highlights a table row when the appropriate checkbox is checked. Using element.style is a bit messy and doesn't really fulfil my needs..
I want to just be able to use className, but when I uncheck a row I am having difficulty restoring the original (when the page loaded)className, I need to do this because the rows have different styles Is their any other way to access the original className of an element?
I know how to disable the context menu (the right hand mouse button) and how to replace it by my own menu. I also know that not everybody likes this - so let's not discuss about that here.
What I can't figure out and what I would like to know, is:
1) How to ADD elements to it, i.e. keep the original contents and add something to it;
2) How to RESTORE it to its original contents.
Does anyone know the code for a simple working example of these things?

I'm looking at my page: www.mysite.com/index.php?start=0
I scroll to the bottom of the page with the vertical scroll bar, and then click the pagation link to start on page 2, record #50: www.mysite.com/index.php?start=50
Of course, the vertical scroll bar jumps back to the top of my page.
Is there a way to make it remember that the scroll bar was at the bottom (or in the middle)?

What I’m trying to accomplish is set an attribute called opacityin any element with a specified value that can be used to toggle whenever the user hovers over the element. The code below works perfectly but one other thing I would like to be able to do is retrieve the attribute opacity after the document loads and fade the element to that value instead of hard coding the ".66". This is probably fairly easy I've just never ran into a situation where I needed to do this.[code]...
