JavaScript - Need Help With The Expandable Divs

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

I want to create a link which doesn't takes you to anew page but just expands to show it's information . Exactly like the one in FAQs where you click the question and the page expands to show you the answer.

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:

Again thank you so much! Any questions just ask!

I have this simple checkbox menu
http://myresearchfinder.com/dev/checktest.html

If you check the cancer box a div will appear. If you check lung, another menu pops up. If you check colon nothing appears because it's behind the lung div. I am aware of z-index. But because a person may go back and forth between menus I need a way to make sure the appropriate div is always on top. Any ideas?

Hi, I wondering if anyone can help:

I've got rows of divs in this manner

<div class="row">This is row 1 <a href="click">click here to show more</a></div>
<div class="hidden row"><p> hidden text for row 1</p></div>
<div class="row">This is row 2 <a href="click">click here to show more</a></div>
<div class="hidden row"><p> hidden text for row 2</p></div>
<div class="row">This is row 3 <a href="click">click here to show more</a></div>
<div class="hidden row"><p> hidden text for row 3</p></div>
<div class="row">This is row 4 <a href="click">click here to show more</a></div>
<div class="hidden row"><p> hidden text for row 4</p></div>

I wish to have some javascript to toggle the hidden row for its corresponding link.

Please can someone help point me to an example if available. Any help will be greatly appreciated

Hey there.

I want to move a div around a page, and I do this by getting the original top and left values of a div, and then change them.

But the problem is getting the original values; I checked online and thought that this would work:

Code:

	var chart = document.getElementById(charDiv).style.top;
	var charl = document.getElementById(charDiv).style.left;
	alert('char_t:' + chart + ' char_l:' + charl + 'charDiv:' + charDiv);

charDiv is passed into the function (its the id of the div I want to move). I know that charDiv has a value by looking at the values of the alert() statement, but the values of chart and charl are empty. The alert simply outputs

char_t: char_l: charDiv: charOne

any help would be appreciated

So I have a few divs that I'm hiding and showing whenever a you click on a link. So I'm a newbie at JavaScript and this is the best way I know how to do this.


var divElement = '';
function show(divElement) {

if(divElement == 'add') {
document.getElementById('uploadImages').style.display='none';
document.getElementById('addTutorial').style.display='block';
document.getElementById('editTutorial').style.display='none';
document.getElementById('tutorialsImages').style.display='none';
document.getElementById('pendingTutorial').style.display='none';
document.getElementById('deletedTutorial').style.display='none';
}
else if(divElement == 'edit') {
document.getElementById('uploadImages').style.display='none';
document.getElementById('addTutorial').style.display='none';
document.getElementById('editTutorial').style.display='block';
document.getElementById('pendingTutorial').style.display='none';
document.getElementById('tutorialsImages').style.display='none';
document.getElementById('deletedTutorial').style.display='none';
}
else if (divElement == 'images') {
document.getElementById('uploadImages').style.display='none';
document.getElementById('addTutorial').style.display='none';
document.getElementById('editTutorial').style.display='none';
document.getElementById('pendingTutorial').style.display='none';
document.getElementById('tutorialsImages').style.display='block';
document.getElementById('deletedTutorial').style.display='none';
}
else if(divElement == 'pending') {
document.getElementById('uploadImages').style.display='none';
document.getElementById('addTutorial').style.display='none';
document.getElementById('editTutorial').style.display='none';
document.getElementById('tutorialsImages').style.display='none';
document.getElementById('pendingTutorial').style.display='block';
document.getElementById('deletedTutorial').style.display='none';
}
else if(divElement == 'upload') {
document.getElementById('uploadImages').style.display='block';
document.getElementById('addTutorial').style.display='none';
document.getElementById('editTutorial').style.display='none';
document.getElementById('tutorialsImages').style.display='none';
document.getElementById('pendingTutorial').style.display='none';
document.getElementById('deletedTutorial').style.display='none';
}
else if(divElement == 'delete') {
document.getElementById('uploadImages').style.display='none';
document.getElementById('addTutorial').style.display='none';
document.getElementById('editTutorial').style.display='none';
document.getElementById('tutorialsImages').style.display='none';
document.getElementById('pendingTutorial').style.display='none';
document.getElementById('deletedTutorial').style.display='block';
}

}


That is a awful lot of code to do just a few simple things. But don't get me wrong it works... I just wondered if there is a cleaner way of doing this.

Thanks,

I was wondering how I could redirect from one div to another div after " x " seconds on the same page.. Is this possible?

So like basically:

Index page: > Shows div1, after x seconds shows div2 etc..

I have five DIV tags that contain a photo and brief bio for partners of an accounting firm. I need to randomize these DIV tags (id="d1" - "d5") to display only one of the tags on each page load.

Normally, I would do this with ColdFusion but the client isn't willing to purchase the language support for their hosting system.

A sample of one of the DIVs is below.

Code:

<div id='d1'>
      <div class="subhead1">Shareholder Spotlight</div>
      
      <img style="float:left;margin:12px 10px 0px 0px" src="images/leonard_summer_photo.jpg">
      
      <div class="subhead2">Leonard M. Sommer, CPA</div>
      
      <div class="subhead3">Managing Shareholder</div>
      
      <div class="body">Leonard has more than 30 years experience in providing tax, business and succession planning advice for family-owned and closely-held businesses. <a href="leonardsommer.html" style="color:#3d3d3d; text-decoration:underline">Learn more</a>.</div>
      </div>

If someone could let me know how to do this in javascript I would appreciate it. You'll have to be very clear in your instructions as I don't know javascript very well.

Thank you in advance for your response!

Here is the code I'm using:
Code:

<style type="text/css" rel="stylesheet" href="">
li#button {
cursor:pointer;
}

</style>
<script type="text/javascript">
var num = 6; // this is # of divs you have
function swap(what)
{
for(var i = 0; i < num; i++)
{
document.getElementById('swap'+i).style.display = 'none';
}
document.getElementById('swap'+what).style.display = 'block';
}
var createStyle = document.createElement('style');
var createStyleProp = document.createTextNode('.hidden { display:none; }');
createStyle.appendChild(createStyleProp);
document.getElementsByTagName('head')[0].appendChild(createStyle);
</script>

<body> 
  <div id="content">
   <ul id="a-menu">
      <li id="button" onClick="swap(0)"><b>button1</b></li>
      <li id="button" onClick="swap(1)"><b>button2</b></li>
      <li id="button" onClick="swap(2)"><b>button3</b></li>
   </ul>
<div id="swap0" class="block">content 1</div>
<div id="swap1" class="hidden">
    <ul id="submenu">
       <li id="button" onClick="swap(3)">button1</li>
       <li id="button" onClick="swap(4)">button2</li>
       <li id="button" onClick="swap(5)">button3</li>
       <li id="button" onClick="swap(6)">button4</li>
      </ul> 
       <div id="swap3" class="block">content 2</div>
       <div id="swap4" class="hidden">content 3</div>
       <div id="swap5" class="hidden">content 4</div>
       <div id="swap6" class="hidden">content 5</div>
       
 </div>
<div id="swap2" class="hidden">content 6</div>
                  </div> 
 </body>
</html>

Is working fine for the first three buttons but the subdivs from swap1(div) are not working. Can anyone help me with this??

Hi, I have a good toggle script that does what I want for the most part.

I have a set of links. When you click one the content in that div replaces the previous content. When you load the page, the content of link one shows.

However, I would like to have different content show, not related to any of the links, when the page first loads. Once you click on any of the links that copy will get replaced with the corresponding copy.

I am attaching the code and a link to the page.

Code:

<!-- Hide/Show -->
<script type="text/javascript">
	window.onload=function() {
	var aObj=document.getElementsByTagName('a');
	var i=aObj.length; 
	while(i--) { 
		aObj[i].count = i;
		aObj[i].onclick=function() {return showHide(this);};
		showHide(aObj[i]);
		}
	};
	
	function showHide(obj) {
	var aDiv=document.getElementById('wrapper').getElementsByTagName('div');
	if (typeof showHide.counter == 'undefined' ) {
		showHide.counter = 0;
		}
	aDiv[showHide.counter].style.display = 'none';
	aDiv[obj.count].style.display = 'block';
	showHide.counter = obj.count;
	return false;
	}
</script>
