autodisplay (but not permanent) submenu

Poster: molesquirrel
Dated: Wednesday December 25 2002 - 2:53:25 GMT

Hey -

I'm looking into creating a submenu that appears by default (kind of like the always visible flag), but adheres to the timegap variable, and will close after awhile. To put it another way, I'm going to have a menu selection that dynamically loads some sentence of information, and I want it to appear on the screen for a little bit, but disappear after some set period of time, or after they click on it. I realize that using the Menu for this isn't the most clean cut way, but I'm already using the Menu for other elements on my page, and if I could extend it to handle this, all the better.

Thanks for your time~

Hi molesquirrel,

I have some ideas. You could probably achieve the desired effect with a few small, additional functions that'll hook into existing functions in mmenu.js. But before I jump into it, I have some questions about specifics:

(1) Do you want to show an actual menu, with multiple items, or just something more like a popup text box?

(2) What event(s) will trigger the showing of the timed menu? On the one hand, your description makes it sound like you want the menu to appear automatically when the page loads (Always Visible), but you also describe having the timed menu appear as the result of another menu selection. Both maybe?

(3) Will clicking on the "popup" menu simply dismiss it, or do you want it to be able to link to a url as well?

To answer your questions:

(1 & 3) Popup text box. Clicking on it will do nothing but make it disappear.

(2) Some dynamic code (php) will decide if this 'box' is to be included - so on page loadup, it will know where or not it should appear. It should stay up for some timed period. One thing I might have neglected to mention is that I'd like to have different 'time out' periods for this box and the rest of the menu. If I have a sentence in the box saying 'you are logged in to the site', or whatever, I might want it to stay up to 10 seconds, whereas a menu might collapse at half a second.

I did some browsing since I posted the original message, and found a way to do this using only a few lines of code bent towards dhtml, so if you are busy at all, I wouldn't worry about trying to put together something for this; I appreciate your response thus far.

Thanks for the answers. Out of curiousity, I already figured out how you could do what you want using the menus. If you're interested, let me know and I'll follow up. Otherwise, I'll assume you plan to stick with the other method you found.

After some more thought, I think it would be beneficial to see what you thought of; another little feature I'd like would be possible if the menu was integrated with the popup box. So, let me know what you have. Thanks!

OK, here goes...

It'd probably be easier if I could attach a .zip. As it is, I'll just paste the relevent code into code boxes here, and you can cut and paste the box contents to recreate the pertinent files on your end.

Rather than go into my usual, extensive (and sometimes too wordy) explanations, I'll just give you the files I was working with while I was playing around. You'll probably be able to figure out the functions, and how the various examples use them.

All three of the following files go in the same directory, along with a copy of mmenu.js

(1) index.html -- a small file I was using to test the various functions:

Code: Select all

Fusce suscipit metus at lorem. Mauris volutpat pretium arcu. Ut nibh velit, cursus eget, imperdiet bibendum, aliquam id, lectus. Fusce laoreet purus quis justo. Curabitur posuere.<br>


(2) kc_timedMenus.js -- contains the custom functions to control timed popups/menus. All "popups" are essentially menus in the sense that they are constructed using the addmenu() function, but popups with no real links are like a basic popup textbox. The code is pretty straight forward; I've also added some comments for each function to document the parameters being passed. Please be kind ;) ... as I said, I was just playing around out of curiosity... the code could probably be improved here and there! At least you'll get an idea of the various approaches I had in mind. Feel free to make improvements (and to let me know what they are, if you like).

Code: Select all

var kc_menuTimer = 0;

// Check to see if menuName is still open.

function kc_isOpen(menuName)
  var menuStyle = gmstyle("menu" + getMenuByName(menuName));

  if (ns4) {
    return (menuStyle.visibility == "show");
  else {
    return (menuStyle.visibility != "hidden");

// Set menuName's AlwaysVisible property (1 or 0), then show menuName.  If alwaysVis = 0
// menuName will close when calling submenu (and others from the same main menu) close.
// If alwaysVis = 1, menuName will remain open until manually closed.

function kc_showMenu(menuName, alwaysVis)
  var menuNum = getMenuByName(menuName);
  var menuArr = eval("menu" + menuNum);
  menuArr[7] = alwaysVis;
  SDiv("menu" + menuNum, 1);

// If menuName is currently open, close it.

function kc_hideMenu(menuName)
  if (kc_isOpen(menuName)) SDiv("menu" + getMenuByName(menuName), 0);
  if (kc_menuTimer) clearTimeout(kc_menuTimer);

// Show menuName for openTime milliseconds and close the calling menu.

function kc_timedMenu(menuName, openTime) // use of popup() closes calling menu
  var menuArr = eval("menu" + getMenuByName(menuName));
  menuArr[7] = 1;
  var functionStr = "kc_hideMenu('" + menuName + "')";
  kc_menuTimer = setTimeout(functionStr, openTime);

// Show menuName for openTime milliseconds and leave the calling menu open.

function kc_timedMenuCallerOpen(menuName, openTime) // leaves calling menu open
  kc_showMenu(menuName, 1);
  var functionStr = "kc_hideMenu('" + menuName + "')";
  kc_menuTimer = setTimeout(functionStr, openTime);

// Open the url in a new window.  windoName = the new window's name attribute.
// t = top coordinate, l = left, w = width, h = height, callingMenuNames = a
// comma-separated string (NO SPACES) of menu names to close when the new window
// opens (i.e., to close an entire cascade of submenus).

function kc_linkToNewWindow(url, windowName, t, l, w, h, callingMenuNames)
  var winAttributes = "resizable=yes,scrollbars=yes,dependent=yes" + ",top=" + t + ",left=" + l + ",width=" + w + ",height=" + h;

  var menusToClose = callingMenuNames.split(",");
  for (var i in menusToClose) kc_hideMenu(menusToClose[i]);

  var newWin =, windowName, winAttributes);

// onload event handler... causes a popup textbox on load.

window.onload = function()

function on_load()

(3) menu_array.js -- standard array file to integrate the Popup Examples into a normal menu (borrowed partially from the horizontal menu sample on the Milonic site). Comments above each example in the code briefly explains what the example does... study the examples, the calling menus, and the result to see how it works.

Sorry for the long post. I didn't know a better way to do it (wish we could attach files). I should point out that I have not tested this code extensively... just played around with it on IE6, NS7, NS4.75, and Opera 6.05 under Win2k pro. It worked reasonably well with all of these combinations; best on IE6 (my preferred browser). You may want to do further testing if your target audience uses other combos (e.g., Macs).

This should work right out of the box. If not, something may have gotten screwed up in the transfer; let me know and we can see about emailing you the files. Also, I realize that just because my code makes sense to me, doesn't mean it makes sense to other people! So, if you have questions, please feel free to ask.

I had fun doing this, and I'll probably end up using some of it myself in the future. I hope you also find some of it useful.
