I'm trying to convert some code from mootools to prototype, but I can
get the first ul to work but none of the others add the hover class on
mouseover. its got something to do with the call to
getElementBySelector - any help appreciated
Event.onDOMReady(function(){
alert('DOM is loaded!');
element = $('menu')
if(!element.hasClassName('disabled')) {
var menu = new JMenu(element)
document.menu = menu
};
});
var JMenu = Class.create(); // added pd
JMenu.prototype = { // added pd
initialize: function(el){
var elements = el.getElementsBySelector('li');
alert(elements.length);
var nested = null;
for (var i = 0; i < elements.length; i++) {
var element = elements[i];
//alert(elements.length);
Event.observe(element, 'mouseover', function(){
this.addClassName('hover');
});
Event.observe(element, 'mouseout', function(){
this.removeClassName('hover');
});
//find nested UL
//nested = $E('ul', element);
nested =
element.getElementsBySelector('ul').first;
if (!nested) {
continue;
}
//declare width
var offsetWidth = 0;
//find longest child
for (k = 0; k < nested.childNodes.length; k++) {
var node = nested.childNodes[k]
if (node.nodeName == "LI")
offsetWidth = (offsetWidth >=
node.offsetWidth) ? offsetWidth :
node.offsetWidth;
}
//match longest child
for (l = 0; l < nested.childNodes.length; l++) {
var node = nested.childNodes[l]
if (node.nodeName == "LI") {
$(node).setStyle('width',
offsetWidth + 'px');
}
}
$(nested).setStyle('width', offsetWidth + 'px');
}
}
};
