Element Visibility During Scrolling

Nov 23, 2005

I'm trying to figure out which elements of a document are visible as the user scrolls the Firefox browser. I haven't written the code yet but I think I should be able to do it by keeping track of the current display using the following properties:

window.content.scrollX, window.content.scrollY,
window.content.innerWidth, window.content.innerHeight. -- with these 4
I can determine which part of the document is visible.

Then for each element I can figure out its display position using, offsetWidth, offsetHeight, offsetTop, offsetLeft. This would entail traversing the DOM and perculating the offset values down to all the children.

While this would likely work, it seems inefficient. Do you know of any other ways to determine which elements are actually on the screen?

Set Element Visibility Using Switch/Case?

Nov 19, 2010

So, I have a list of items that need to have a new preset list item appear based on what day it is. I have the date script working (to test, change the first case to some random date and change the third case to todays date - 10192010 - It will fire that document.write). What I need the cases to do though, is set the visibility of certain list items.

This is just an example, there will be around 20 list items in the final project. As you can see in the first two cases, I've tried a couple different routes to no avail.

The Code (class references are irrelevant to this example, they belong to the final project):

<html>
<head>
<script type="text/javascript" language="JavaScript">
/*

[Code]....

Toggle Visibility Of Element - OnClick Function

Sep 6, 2009

I found this little script and it works fine but the only thing is when the page first loads it displays the "This is foo" text. I would like it to not display the text until it is clicked. So instead of it displaying "This is foo" when the page loads I would like it to not display anything.

Here is the script:
Code:
<body>
<script type="text/javascript">
<!--
function toggle_visibility(id) {
var e = document.getElementById(id);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
//-->
</script>
<a href="#" onclick="toggle_visibility('foo');">Click here to toggle visibility of element #foo</a>
<div id="foo">This is foo</div>
</body>

Change SPAN Visibility With SELECT OPTION?

Jan 1, 2010

I know this will have been covered but search isn't working for me at the moment. Easy one for people who know JS anyway, I'm sure: I have a SELECT box that precedes a text input, however, when a particular option is selected (the value of which is "BETWEEN") I need a hidden SPAN to become visible. It is hidden as default with "visibility:hidden;" so I need to just change it to "visibility:visible;" if memory serves. Anyway, likewise, if it is already visible, I need it to be both hidden and have the input in that span have an empty value. Any tips? I need to apply this to many rows in a table, so a function that I can call with the span and input IDs would be best I reckon.

Simple Browser Detect Then Change Visibility Of A Layer?

Aug 22, 2011

I am using CSS text-shadow but of course IE doesn't like it. I've looked into some methods for achieving the same effect in IE, but it's not at all the same so I've opted for another method..I'm going to have two layers. In layer1, it will be standard text, shadowed with CSS. I then screenshotted that and will use the resulting jpeg for layer2.I was then planning to find a script that:1. Detects if browser is IE2. If IE, layer2 is visible, layer1 is invisible3. If not IE, layer1 is visible, layer2 is invisibleThe problem is that I can't find a simple script to detect if the browser's IE or not. I can find loads of scripts that check what version of IE someone's using. The version isn't important!

How To Change One Element To Another?

Aug 21, 2006

I would like to have an element, a text string, change into a select
when a mouseover occurs and then change back to text when a selection is
made or when a mouse out occurs. I looked a t using dojo for this,
http://dojotoolkit.org, but this will end up on a production server,
where dojo is not installed and cannot be installed. So, I need another
solution. Can someone give some pointers on how this might be done?

Watch For Form Element Value Change

Dec 24, 2005

Mozilla-based browsers have watch and unwatch methods to detect change
in value of form elements (or any Javascript variables really). IE
doesn't support this.

Is there a a reliable cross-browser way alternative to this? Something
that will let me detect a change in value for a form element and
trigger my own callback function upon change?

Hopefully, something that is generic enough to be called as
"MyWatch(element)"!

JQuery :: Change An Attribute Of An Element?

Jun 24, 2010

I am trying to change an attribute of an element but can't figure out what the selector is to select it.

the page code is like this

<div class="slideshow" id="slideshow"><span class="image-wrapper current" style="opacity: 1;"><a title="" href="#2" rel="history" class="advance-link"> <img alt="" src="images/samples/1.jpg"></a></span></div>

I want to add a top css attribute to the img tag.

I tried many things such as

$('.advance-link:first')
$('.advance-link:firstChild')

but none seem to be working. The img gets generated by another script so I can't add an id or class to it. I figured an expert at selectors would be able to explain how to select it.

Change The Colour Of The First Word In An H2 Element

Feb 25, 2011

I am trying to add some styling to the first word of all of my H2 headings.

Now obviously this would be very easy to do using a span, but let me clarify my situation.

I am working on a Joomla! site, so a lot of my code is read from php and sql files. I thus can't go and wrap my text in a span by hard coding it since it is dynamic and read from a database.

I thus decided that manipulating it using javascript will be the simplest. The only other chice is to write a php script that does pretty much the same thing, but I prefer javascript.

So here is what I am thinking of doing:

I want to select all of the H2 elements from my document, get access to their text content, single out the first word, and then wrap it in a span. The span will have a class, which will then simply be styled using CSS.

I though I was on a roll, but is seems that I have hit a snag. I am able to select and edit a single element with an id, but not all of the H2 elements in my document.

I was using 'getElementById' and assumed I could simply change it to 'selectElementByTagName' at some point.

I then used 'innerHTML' to retrieve and manipulate the contents.

Here is my code so far, and it work to some extent:

Code:

It seems though that 'innerHTML' does not work with 'selectElementByTagName', and I can't seem to find a similar command that does.

I also can't use ID's since I can't manipulate the HTML (at least not without scratching through a whole mess of php). Even then I need to manipulate various elements on one page, so ID's are no good anyway.

So my question finally is this: Is there a similar command I could use, or am I busy going in the wrong direction?

Change Height And Width Of An Element?

May 5, 2010

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:

<HEAD>
<script type = "text/javascript">

Change Attributes When Removing Element

May 9, 2011

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

Jul 5, 2011

The competition is that there is a table width a heckbox inside and if the ckeckbox is checked the tr of this checkbox should get class "sel" and remove this class if it get unchecked. So the problem with the actual code is that everytime a new checkbox got checked the <tr> of the checkbox which was checked before losts the class "sel" and just the last checked checkbox will get it. Do you have an idea how the could must look like to get it work?

Html like this:

<table>
<tr><td><input type=”checkbox” class=”cbU”></td></tr>
<tr><td><input type=”checkbox” class=”cbU”></td></tr>
<tr><td><input type=”checkbox” class=”cbU”></td></tr>
<tr><td><input type=”checkbox” class=”cbU”></td></tr>

[Code]....

Even if the else will be deleted the problem is stil there so the failure must be in my code.
