JavaScript - Expandable Menu Help

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.

Hello,

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

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.

Thanks for the time.

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:

the html was too long, so i uploaded it to my webspace

Again thank you so much! Any questions just ask!

Hi Exprts,

I am using a (anylink)javascript menu from dynamic drive. Basically I am having a design issue but posting the problem here because I think this can be fixed through JS.

Please download the attached files. You will see the menu & the sub menu on mouse over. Problem is that.... when the submenu appears & I take my mouse to the sub menu, the parent item hover style disappears. I mean, it doesn't look active. I just want the parent item active when users moves his/her mouse to sub menu. Thats all.

Please suggest me any solutions for this. Thank you in advance.

Hi all, this is my first post so forgive me for any errors but i'll try and give all the information i can. i use Xara Designer Pro and i have used a 3rd party software to create a html menu however i have a html loading screen on my site and the menu always appears on top of the screen and while the screen is loading, this is the only thing that appears on top everything else is fine, i have put this to the people on the xara forums and the opinion is that its probably the JS file that the menu is using that is telling it to appear on top. i was wondering what i should look for to determin this problem or if someone could take a look at it for me? i'll upload the JS here and see if anyone can help. my site is at www.pcevo.co.uk however you need to CTRL + F5 to refresh wihtout the cache to see the loading screen if you are on a fast connection.

I'm creating a menu using html, css and a javascript, I found a tutorial to follow online. What I am trying to achieve is when the mouse hovers over the menu items, each item will have a different colour background. the problem is that i can do this but it only works with one colour and not different colours.

this is the html:

Code:

<ul>
<li><a href="1.php">Things</a></li>
<li><a href="2.php">Animals</a>
  <ul>
    <li><a href="2-1.php">Cani</a>
        <ul>
          <li><a href="2-1-1.php">Domestic dogs</a></li>
          <li><a href="2-1-2.php">Wolves</a></li>
        </ul>
    </li>
    <li><a href="2-2.php">Felidae</a>
        <ul>
          <li><a href="2-2-1.php">Domestic cats</a></li>
          <li><a href="2-2-2.php">Wild cats</a></li>
        </ul>
    </li>
  </ul>
</li>
<li><a href="3.php">Humans</a></li>
</ul>

the css is as follows:

Code:

div#s1 {
width: 200px;          /* menu width */
}

div#s1 ul {
background-color: #036;
list-style-type: none; /* get rid of the bullets */
padding:0;             /* no padding */
margin:0;              /* no margin for IE either */
}

div#s1 ul li {
margin: 0;
padding: 0;
background-color: #036;
display:block;
border-top: 1px solid white; /* lines */
}

div#s1 ul li a {
display: block;         /* lines extend to right, make area clickable */
color: white;
background-color: #036;
padding: 3px 3px 3px 23px;
margin:0;
text-decoration: none;
height:15px;           /* hint for IE, alternatively remove whitespace from HTML */
}

div#s1 ul ul li a {
margin-left: 20px;     /* indent level 1 */
}

div#s1 ul ul ul li a {
margin-left: 40px;     /* indent level 2 */
}

div#s1 ul ul ul ul li a {
margin-left: 60px;     /* indent level 3 */
}

div#s1 li ul, div#s1 li.open li.closed ul {
display: none;         /* collapse */
}

div#s1 li.open ul {
display: block;        /* expand */
}

div#s1 ul li.open a {
background-image: url(bullet_open.gif);
background-repeat: no-repeat;
}

div#s1 ul li.closed a {
background-image: url(bullet_closed.gif);
background-repeat: no-repeat;
}

div#s1 ul li.leaf a {
background-image: url(bullet_leaf.gif);
background-repeat: no-repeat;
}

div#s1 li.active a {
background-position: 0px -20px;
color: red;            /* highlight text */
}

div#s1 li.active li a {
background-position: 0px 0px;
color: white;          /* fix lower levels */
}

div#s1 ul li a:hover {
color: red;
background-color: #06C; /* rollover effect */
}

and finally the javascript:

Code:

var menu_active_class = "active";
var menu_leaf_class = "leaf";
var menu_open_class = "open";
var menu_closed_class = "closed";

//the default page that is displayed if URL ends in /
var menu_default_page = "index.php";
var menu_url;

//main function
//menu_id : id of the element containing the navigation
function menu_main(menu_id) {
 var url = location.href;
 if (url.lastIndexOf("/") == (url.length-1)) {
   url = url+menu_default_page;
 }
 if (url.lastIndexOf("?") >= 0) {
   url = url.substring(0, url.lastIndexOf("?"));
 }
 if (url.lastIndexOf("#") >= 0) {
   url = url.substring(0, url.lastIndexOf("#"));
 }
 menu_url = url;

 var main = document.getElementById(menu_id);
 if (!main) alert("No element with id '"+ menu_id +"' found");
 menu_traverse(main);
 }

 /* Walks down the subtree and on the way back
 sets properties.
 returns bit set
         1: set = element is a node, unset = element is a leaf
         2: set = element contains the active node
         4: set = element is the active A node
*/
function menu_traverse(element) {
var props  = 0;

// walk down
for (var i=0; i<element.childNodes.length; i++) {
  var child = element.childNodes[i];
  props |= menu_traverse(child); // aggregate bits
}

// on the way back now
switch (element.tagName) {
  case "UL":
    props |= 1;
    break;

  case "LI":
    var c1 = (props & 1) ? 
               ((props & (2|4)) ? menu_open_class : menu_closed_class)
             : menu_leaf_class; 
    element.className = element.className ? element.className+" "+c1 : c1;
    if (props & 4) {
      if (!(props & 2)) element.className += " "+menu_active_class;
      props |= 2;
      props &= 1 | 2; // reset bit 4
    }
    break;

  case "A":
    if (props & 2) break; // once is enough
    var href = element.getAttribute("href");
    if (menu_isSameUrl(menu_url, href)) props |= 4;
    break;
  }

  return props;
}

//matches two URIs when href is the last part of url
//.. and . are correctly resolved
function menu_isSameUrl(url, href) {
var a = url.split(/[?\/]/i);
var b = href.split(/[?\/]/i);
var i = a.length - 1;
var j = b.length - 1;
while ((i >= 0) && (j >= 0)) {
  if (b[j] == "..") { j-=2; continue; }
  if (a[i] == "..") { i-=2; continue; }
  if ((b[j] == ".") || (b[j] == "")) { j--; continue; }
  if ((a[i] == ".") || (a[i] == "")) { i--; continue; }
  if (! (a[i] == b[j])) return false;
  i--;
  j--;
 }
 return true;
}

New to this forum but hope this will explain my problem, any help is much appreciated!

thanks!!

? how would i make it for a menu so you could press it and it would go down to click on a link.

Hello all,

I am currently looking to create a JavaScript menu for a website I am working on. It currently expands and collapses on click. The code in question is pasted below:-

menu_status = new Array();

function showHide(theid){
if (document.getElementById) {
var switch_id = document.getElementById(theid);

if(menu_status[theid] != 'show') {
switch_id.className = 'show';
menu_status[theid] = 'show';
}else{
switch_id.className = 'hide';
menu_status[theid] = 'hide';
}
}
}

As you can see, it basically shows and hides the menu (when clicked). I want it to open the menu when clicked and close when another menu is opened. I have looked and have not been able to find a solution into it. Ideally I donot want it to be a long piece of code as I do have a working menu but with many more lines of JavaScript than the one I have posted.

I need a solution to it urgently, your help is appreciated.

Thanks

Hi there,

I am trying to create "sideways" sub menus off of my main vertical menu images.
(Something like this example: http://netweblogic.com/demos/ddm/vddm-nomoo.htm
but in the place of Menu Item 1, Menu Item 2, Menu Item 3 there would be roll over images.)

The main vertical menu items I have are rollover images.
I would like the sub menu to appear when you hover over the main menu item.

When I attempt this using the above example, all of my other CSS and JS does not work.

Any help on how to link my rollover menu images to the sub menu would be greatly appreciated! Thanks in advance!

Here is the code for my menu (I have only included 2 menu items here, if you need more info please let me know):


Code:

<script type="text/javascript">
<!--
function MM_swapImgRestore() { //v3.0
  var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
function MM_preloadImages() { //v3.0
  var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
    var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
    if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}

function MM_findObj(n, d) { //v4.01
  var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {

Here is my CSS code for the menu, not sure if this is where the issue is?

Code:

/* navigation menu */
#navcontainer ul {
margin: 0;
padding: 0; 
list-style-type: none; /* removes bullets */
background-image:url('background.jpg');
}

#navcontainer li {
margin: 0 0 0 0; /* separates list items */
}

#navcontainer a
{
display: block; /* achieves rollover */

width: 250px; /* list width */

text-decoration: none;

}

I know how to edit the CSS, and minute parts of the JavaScript code (for example; speed of the drop). The problem is, I had a massive amount of help making the Javascript side of the menu, and do not know how to edit it...

I want the rules to still apply, where only one can be expanded at a time (one of the first drops, and then only one of the sub-drops). I noticed in the code, I can edit it so there can be more than one drop, but that would mean, the whole menu could be expanded

Also, I want my sub-drops. to have different span colour than the main drop. but trhe links and such, (everything else about it) can be the same....

My live demo is here!


Thank you for any help and/or advice in advance,

Hi!
I'm relatively new to JavaScript, though I've done some PHP and Java programming before. Still, be gentle .

I have a menu with some images as the links. These images have onmouseover() and onmouseout() functions where the image is changed (onmouseover makes the image blue, while the onmouseout restores the original white).

Now, my problem is that I also want to make the link corresponding to the currently open page to stay blue all the time, but I cannot for the life of me figure out how to do it. I've tried with

onClick="document.[IMG].src='blue'"

but clearly, as the page reloads to open the chosen link, the image is reset to white. I've also tried some other, unsuccessful solutions that don't need mentioning here...

How do I make the image stay blue even when the page is reloaded? I'd be really happy if you could point me towards some examples of this being done.

This is parts of my code (it's not much and I know it's a bit of a mess, it's in the developmental stages...):

Code:

function printHTMLTop()
{
var html = '<div class="main" id="main"> \
<div class="header" id="header">\
<div class="topHeader" name="topHeader"> \
<div class="logo" name="logo"><a href="index.php"><img src="logoBlue02.png" /></a></div> \
&nbsp; \
</div> \
<div class="midHeader" name="midHeader"><img src="midHeadImg.png" /></div> \
<div class="bottomHeader" name="bottomHeader"> \
<div class="menu" name="menu"><a href="index.php"><img name="hem" id="hem" src="menu_HemW.png" onmouseover="document.hem.src=\'menu_HemB.png\'" onmouseout="document.hem.src=\'menu_HemW.png\'" /></a></div> \
<div class="menu" name="menu"><a href="Contract.php"><img name="skapa" src="menu_SkapakontraktW.png" onmouseover="document.skapa.src=\'menu_SkapakontraktB.png\'" onmouseout="document.skapa.src=\'menu_SkapakontraktW.png\'" /></a></div> \
<div class="menu" name="menu"><a href="gbookAdd.php"><img name="gbook" src="menu_GbookW.png" onmouseover="document.gbook.src=\'menu_GbookB.png\'" onmouseout="document.gbook.src=\'menu_GbookW.png\'" /></a></div> \
<div class="menu" name="menu"><a href="Forskning.html"><img name="forskning" src="menu_ForskningW.png" onmouseover="document.forskning.src=\'menu_ForskningB.png\'" onmouseout="document.forskning.src=\'menu_ForskningW.png\'" /></a></div> \
<div class="menu" name="menu"><a href="Intervjuer.html"><img name="intervju" src="menu_IntervjuerW.png" onmouseover="document.intervju.src=\'menu_IntervjuerB.png\'" onmouseout="document.intervju.src=\'menu_IntervjuerW.png\'" /></a></div> \
<div class="menu" name="menu"><a href="Ungdom.html"><img name="ungdom" src="menu_UngdomW.png" onmouseover="document.ungdom.src=\'menu_UngdomB.png\'" onmouseout="document.ungdom.src=\'menu_UngdomW.png\'" /></a></div> \
<div class="menu" name="menu"><a href="Lankar.html"><img name="lank" src="menu_LankarW.png" onmouseover="this.src=\'menu_LankarB.png\'" onmouseout="this.src=\'menu_LankarW.png\'" /></a></div> \
</div> \
</div> \
<div class="mid" id="mid">';

document.write(html);
}

Thanks for your help!
