this.id IE8 undefined, Javascript

Good day Experts :), I have problem with Javascript. It works fine in Firefox 11, IE9 and IE10 but in IE8 I get undefined.

This is the HTML
<div id="menu_container">
<a href="#" id="feedback">Utvärdering/Feedback</a> | <a href="#" id="kontakt">Kontakt</a> | <a href="#" id="open_times">Öppettider</a> | <a href="#" id="abount_uss">Om Asperöd</a>
</div>

Open in new window



function linkEvetListener_1(){
	// Get the links
	var divContainer = document.getElementsByTagName("a");
	var divContainerItems = divContainer.length;
		
	// Loop
	for (var i = 0; i < divContainerItems; i++) {
		addEvent(divContainer[i], "click",  this.clickFunction, false);
	}	
}

Open in new window



function clickFunction(){
	var clickedlinkID = this.id;

	if(clickedlinkID == "kontakt"){
		openCloseDiv("block")
	}
		else{
			hideContentOnLoad();
		}
}

Open in new window


Getting undefined when clicking one of the links. :S Totaly stuck.

Will it be okay for you to consider the possibility of using jquery to take care of cross-browser issues like this?

you can try
1) adding the 'this' parameter to clickFunction()
2) this.getAttribute("id"); instead of this.id
Tom BeckCommented:
If not jQuery then you will have to test for IE version.
function linkEvetListener_1(){
	// Get the links
	var divContainer = document.getElementsByTagName("a");
	var divContainerItems = divContainer.length;
		
	// Loop
	for (var i = 0; i < divContainerItems; i++) {
		var  ieVersion = getInternetExplorerVersion();
		if(ieVersion == -1 || ieVersion > 8){
		    divContainer[i].addEventListener("click",  this.clickFunction, false);
		}else if(ieVersion <= 8){
		    divContainer[i].attachEvent("onclick",  this.clickFunction);
		}
	}	
}
function getInternetExplorerVersion() {
    var rv = -1; // Return value assumes failure.
    if (navigator.appName == 'Microsoft Internet Explorer') {
        var ua = navigator.userAgent;
        var re = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
        if (re.exec(ua) != null)
            rv = parseFloat(RegExp.$1);
    }
    return rv;
}

Hi, thanks for the answer. The answer you provided is more about the clicking function. I tested my own code and it works, it goes to
clickFunction
but from there it gets problematic.

Wery sloppy of me not explaining properly. Anyway I will try.

<div id="menu_container">
<a href="#" id="feedback">Utvärdering/Feedback</a> | <a href="#" id="kontakt">Kontakt</a> | <a href="#" id="open_times">Öppettider</a> | <a href="#" id="abount_uss">Om Asperöd</a>
</div>

The code above generate an nice HTML/CSS menu with different names but goes to the same link, I am trying to extract the id of everylink and it works good. I am trying get the ID from the link you just clicked, for an example if you click Kontakt you shall able to get id"kontakt".

var clickedlinkID = this.id;
That tiny code above works perfectly in FF11 but when trying to do the same in IE8 it gives me undefined.

Allright, I solved after 1½ days of research. It looks like something wrong with
addEvent(divContainer[i], "click",  clickFunction, false);

Open in new window

code. I replace it with
divContainer[i].onclick = clickFunction;  

Open in new window

and fianaly could extract the id with
this.id
.

Now it works for IE8 and FF11

The script I posted should have made it clear that the addEvent() was the problem in IE8. I replaced it with attachEvent() for IE8 and addEventListener() for all others. Your solution is much simpler though. Good work.
