JavaScript - Expandable Sticky Bar

Hello,

I was wondering whether it is possible to expand and collapse forum categories using JavaScript. The forum board I am using is phpBB.

I am building an elearning site where the user is taken through a series of dynamically driven pages to refine their choices. I am using php amd mysql to populate a series of tables but on the last page the table gets very long so i am trying to make the table expandable.

I found this and this on http://www.javascripttoolbox.com/jquery/ and it's proving helpful but i need a little help taking it a step further. I also found this to be useful for anyone else who is trying to do the same thing: http://www.jankoatwarpspeed.com/post...nd-plugin.aspx

FROM JAVASCRIPTTOOLBOX

A common UI is to have a table of data rows, which when clicked on expand to show a detailed breakdown of "child" rows below the "parent" row.
The only requirements a

1. Put a class of "parent" on each parent row (tr)
2. Give each parent row (tr) an id
3. Give each child row a class of "child-ID" where ID is the id of the parent tr that it belongs

Original code:

Code:

$(function() {
	$('tr.parent')
		.css("cursor","pointer")
		.attr("title","Click to expand/collapse")
		.click(function(){
			$(this).siblings('.child-'+this.id).toggle();
		});
	$('tr[@class^=child-]').hide().children('td');
});

This works great but my parent and child rows all contain checkboxes and If i try and check the checkboxes in the master rows the child rows associated with that master row expand and contract. I have added an extra cell to each row and i'm using a css class to add an arrow image to each master row but i am new to Javascript so i am not sure what i am doing.

My code now looks like this:

Code:

$(document).ready(function() {
	$('tr:not(.parent)').hide();
	
	//$('tr.parent')
	$('.arrow')
		.css("cursor","pointer")
		.attr("title","Click to expand/collapse")
		.click(function(){
			$(this).siblings('.child-'+this.id).toggle();
			$(this).toggleClass("up");
		});
	});

So far the arrow image is toggling but i can't seem to work out how to get the .click function to affect the whole row and not just the image. Can anybody help me?

Thanks

Trying to put my finger on how to achieve this result. About half way down on the page linked below you'll see "Recent - Comments - Popular - Tags"
this table expands when you rollover and stays expanded while allowing you to populate the different content. Any help would be greatly appreciated, not even sure if I'm in the right forum.

Hi, I have a web form that I'm creating and it has some expandable checkboxes that need to be restricted based on choice.

This is my criteria:
If someone chooses checkbox number 1, they cannot choose any other checkbox.
If someone chooses checkbox number 2, they may also choose number 3 but not 1 or 4, they must also answer the question that appears below.
If someone chooses checkbox number 3, they may also choose number 2 but not 1 or 4, they must also answer the question that appears below.
If someone chooses checkbox number 4, they cannot choose any other checkbox, and must answer the questions that appears below. One more caveat: If checkbox number 2 is chosen, and they've filled in all three lines of the question below, I need for them to dynamically add more lines as needed.

I have attached my web form so you can see what I've done. I've researched these options and tried code from various examples but I can't seem to get it to work.

Does anyone know how to accomplish all of this? Thank you in advance!

Hey thanks in advance to anyone who can take a peak at my code and hopefully point me in the correct direction.

I have been working on my final project in my javascript class for a bit, and there are a few erros I cant seem to find through firebug or error console.
It is due this evening at midnight, so anyone that could help, I really need this assignment for a decent grade.

Basically there are two issues so far, one needs to be solved so the other can be as well.

First, line 103 - 105 should create a hyperlink to the specified id, but is doesn't return a number. so the link goes no where
it is this code:
PHP Code:
 //create hypertext link to the section heading 
            var linkItem = document.createElement("a"); 
            linkItem.innerHTML = n.innerHTML; 
            linkItem.href = "#" + n.id; 


Next I belive there is a problem with the function expandCollapseDoc(), that might fix itself when the other problem is solved.

The document should expand and collapse with the menu.

Here is my javascript code:

Hi,

I'm trying to make a "sticky footer" that will stay at the bottom of the page and be about 2/3 of the page height. Then, when a button is clicked, the footer will slide down and be only about 1/3 the page height, collapsing the paragraphs on the footer and revealing the content the footer was covering.

My first try at this is to make 3 divs within the sticky footer, and make the middle div the collapsable/expandable div.

VERY hasty example, it will be a brown paper bag with art supplies inside.


Issue A: What is the best way to create the smooth collapse/expand effect on the middle div using javaScript or jQuery?

Issue B: All of the CSS based sticky footer fixes that I've found require the main div to have a bottom padding or margin of the footer's height. How can I fix this for the footer's two heights (with and without the middle section)? Is there a javaScript or jQuery way to do an expandable sticky footer?

Issue C: The sticky footer fix makes it so that the bottom footer doesn't cover the content above it, but I WANT it to cover the content in this case, is there a better way to do this? Absolute positioning the footer?

Html
Code:

<body>
<div id="whole">
<div id="push"></div>
</div>
<div id="top"></div>
<div id="hide"></div>
<div id="bottom"></div>
</body>

Css
Code:

*{margin:0}
html, body {height: 100%;}

#whole {
	background-color: #09F;
	min-height: 100%;
	height: auto;
	height: 100%;
	margin: 0 auto -150px;}
	
#push {min-height:150px; height:auto;}

#top {
  height: 50px;
  clear:both;
  background-color:yellow;}

#hide {
  min-height: 50px;
  height:200px;
  clear:both;
  background-color:green;}

#bottom {
  height: 50px;
  clear:both;
  background-color:red;}

Hello i have a sticky tooltip that when is in "sticky mode" the only way to close it is by clicking outside of it. I wanted to add a mouseover link for a close link so it can also be closed that way.
original code: http://www.dynamicdrive.com/dynamici...ckytooltip.htm

this is my external .js code and if you look about 11 lines down i have the mouseover link setup for the word "CloseMe". However that's where i need to know how to call it properly?
