Javascript tab menu with rounded corners generator

[serkan sendur]

I have searched for a tab menu script for a long time but none of them was flexible enough,then i created one for me. The algorithm is nice so the script is not too long although being flexible.

your tab menu is in an html table row as follows :

<tr id="foo">
                                <td align="left">
                                    <img alt="" src="images/tab_sol.jpg"></td>
                                <td nowrap="true" align="center" bgcolor="#333333">
                                   foo1  </td>
                                <td align="right">
                                    <img alt="" src="images/tab_sag.jpg"></td>
                                                                <td align="left">
                                    <img alt="" src="images/tabGri_sol.jpg"></td>
                                <td align="center" bgcolor="#646464" >
                                   foo2</td>
                                <td align="right">
                                    <img alt="" src="images/tabGri_sag.jpg"></td>
                            </tr>
in the bottom of your page just add script below to create menu from the markup above :
<script type="text/javascript">
    tableTabControl("foo");
</script>
required script is as follows :
function tableTabControl(anyTdIdFromTabRow)
    {
    var nodes = xGetElementById(anyTdIdFromTabRow).childNodes;
        for(var i = 0; i <  nodes.length; i++)
        {
            if(nodes[i].childNodes[0].nodeName == "#text" || nodes[i].childNodes[0].nodeName== "A")
            {
              
                 
                  addEvent( nodes[i],"click",clickFunction);
                  
                   
                   nodes[i].style.cursor = "hand";
            }
        }
       
        function clickFunction()
        {
        
             for(var i = 0; i <  nodes.length; i++)
            {
                if(nodes[i].childNodes[0].nodeName == "#text" || nodes[i].childNodes[0].nodeName == "A")
                {
                        if( nodes[i] != this)
                        {
                        nodes[i].style.backgroundColor = "#646464";
                        nodes[i].previousSibling.childNodes[0].src="images/tabGri_sol.jpg";
                        nodes[i].nextSibling.childNodes[0].src="images/tabGri_sag.jpg";
                        }
                        else
                        {
                         this.style.backgroundColor = "#333333";
                         this.previousSibling.childNodes[0].src="images/tab_sol.jpg";
                         this.nextSibling.childNodes[0].src="images/tab_sag.jpg";
                       
                        }
                       
                }
            }
         
        }
the following is the crossbrowser generic event registration method :
function addEvent(element, type, handler) {
	if (element.addEventListener) {
		element.addEventListener(type, handler, false);
	} else {
		// assign each event handler a unique ID
		if (!handler.$$guid) handler.$$guid = addEvent.guid++;
		// create a hash table of event types for the element
		if (!element.events) element.events = {};
		// create a hash table of event handlers for each element/event pair
		var handlers = element.events[type];
		if (!handlers) {
			handlers = element.events[type] = {};
			// store the existing event handler (if there is one)
			if (element["on" + type]) {
				handlers[0] = element["on" + type];
			}
		}
		// store the event handler in the hash table
		handlers[handler.$$guid] = handler;
		// assign a global event handler to do all the work
		element["on" + type] = handleEvent;
	}
};
// a counter used to create unique IDs
addEvent.guid = 1;

function removeEvent(element, type, handler) {
	if (element.removeEventListener) 
	{
		element.removeEventListener(type, handler, false);
	} 
	else 
	{
		// delete the event handler from the hash table
		if (element.events && element.events[type]) {
			delete element.events[type][handler.$$guid];
		}
	}
};

function handleEvent(event) {
	var returnValue = true;
	// grab the event object (IE uses a global event object)
	event = event || fixEvent(((this.ownerDocument || this.document || this).parentWindow || window).event);
	// get a reference to the hash table of event handlers
	var handlers = this.events[event.type];
	// execute each event handler
	for (var i in handlers) {
		this.$$handleEvent = handlers[i];
		if (this.$$handleEvent(event) === false) {
			returnValue = false;
		}
	}
	return returnValue;
};

function fixEvent(event) {
	// add W3C standard event methods
	event.preventDefault = fixEvent.preventDefault;
	event.stopPropagation = fixEvent.stopPropagation;
	return event;
};
fixEvent.preventDefault = function() {
	this.returnValue = false;
};
fixEvent.stopPropagation = function() {
	this.cancelBubble = true;
};
