1) Script Title: slashdot menu

2) Script URL (on DD):
http://www.dynamicdrive.com/dynamicindex1/slashdot.htm

3) Describe problem:
trying to resolve the advice I've found for using body onload to include multiple javascript menus on one page. Not directly a slashdot menu problem, but needing a solution to getting two functions from the script sample below into the body onload - the example being: <body onload="shake (); Delay()">

I want two menus on the page, one on right and the other on the left-hand column.
one i can call "left_menu", the other I'll call "right_menu"

<script type="text/javascript">
// <![CDATA[
var myMenu;
window.onload = function() {
myMenu = new SDMenu("left_menu"); // ID of the menu element
// Default values...
myMenu.speed = 3; // Menu sliding speed (1 - 5 recomended)
myMenu.remember = false; // Store menu states (expanded or collapsed) in cookie and restore later
myMenu.oneSmOnly = true; // One expanded submenu at a time
myMenu.markCurrent = true; // Mark current link / page (link.href == location.href)
myMenu.collapseAll(); // Collapse all submenus

myMenu.init();
};
// ]]>
</script>

This should do it:


<script type="text/javascript">
// <![CDATA[
var myMenu;
window.onload = function() {
myMenu = new SDMenu("left_menu"); // ID of the menu element
// Default values...
myMenu.speed = 3; // Menu sliding speed (1 - 5 recomended)
myMenu.remember = false; // Store menu states (expanded or collapsed) in cookie and restore later
myMenu.oneSmOnly = true; // One expanded submenu at a time
myMenu.markCurrent = true; // Mark current link / page (link.href == location.href)
myMenu.collapseAll(); // Collapse all submenus

myMenu.init();
};

var mySecondMenu;
window.onload = function() {
mySecondMenu = new SDMenu("right_menu"); // ID of the menu element
// Default values...
mySecondMenu.speed = 3; // Menu sliding speed (1 - 5 recomended)
mySecondMenu.remember = false; // Store menu states (expanded or collapsed) in cookie and restore later
mySecondMenu.oneSmOnly = true; // One expanded submenu at a time
mySecondMenu.markCurrent = true; // Mark current link / page (link.href == location.href)
mySecondMenu.collapseAll(); // Collapse all submenus

mySecondMenu.init();
};
// ]]>
</script>

There can only be one window.onload - the second one will override the first. And if there is also a body onload event in the body tag after that, it will override the second one.

Use addEventListener/attachEvent instead.

I guess this would work then:


<script type="text/javascript">
// <![CDATA[
var myMenu;
var wO = function(){
myMenu = new SDMenu("left_menu"); // ID of the menu element
// Default values...
myMenu.speed = 3; // Menu sliding speed (1 - 5 recomended)
myMenu.remember = false; // Store menu states (expanded or collapsed) in cookie and restore later
myMenu.oneSmOnly = true; // One expanded submenu at a time
myMenu.markCurrent = true; // Mark current link / page (link.href == location.href)
myMenu.collapseAll(); // Collapse all submenus

myMenu.init();
};

var mySecondMenu;
var wOO = function() {
mySecondMenu = new SDMenu("right_menu"); // ID of the menu element
// Default values...
mySecondMenu.speed = 3; // Menu sliding speed (1 - 5 recomended)
mySecondMenu.remember = false; // Store menu states (expanded or collapsed) in cookie and restore later
mySecondMenu.oneSmOnly = true; // One expanded submenu at a time
mySecondMenu.markCurrent = true; // Mark current link / page (link.href == location.href)
mySecondMenu.collapseAll(); // Collapse all submenus

mySecondMenu.init();
};
if (window.addEventListener){
window.addEventListener('load', wO, false);
window.addEventListener('load', wOO, false);
} else if (el.attachEvent){
window.attachEvent('load', wO);
window.attachEvent('load', wOO);
}

// ]]>
</script>

the javascript for the multiple menus worked great in Firefox but not in IE! Neither menu will work...
any suggestions? Here is the page i'm working with:

The attachEvent syntax is wrong. This:


window.attachEvent('load', wO);
window.attachEvent('load', wOO);

should be:


window.attachEvent('onload', wO);
window.attachEvent('onload', wOO);

There could possibly be other issues. But that much must be fixed first. It may be the only problem.

with this corrected, the menus (both) are not operating in IE

mySecondMenu.init();
};
if (window.addEventListener){
window.addEventListener('load', wO, false);
window.addEventListener('load', wOO, false);
} else if (el.attachEvent){
window.attachEvent('onload', wO);
window.attachEvent('onload', wOO);
}

Nile was really sloppy on this one, there is another problem, should be:


mySecondMenu.init();
};
if (window.addEventListener){
window.addEventListener('load', wO, false);
window.addEventListener('load', wOO, false);
} else if (window.attachEvent){
window.attachEvent('onload', wO);
window.attachEvent('onload', wOO);
}
