Problem with using .getAttribute() :( 2

[Sleidia]

Can someone tell me how to get the tag of x?
I always get the "---- is not a function" error

After an extensive research it looks like you can get the attribute of something only if you have its Id.
Is that so?

The problem is that I want to get the tag type of something that doesn't have an Id.

function defocus( x ) {

    if( navigator.appName == 'Microsoft Internet Explorer' ) {

    self.focus();
    
    } else {

        if (x.getAttribute('tag') == 'a') { // <<< this doesn't work :(
        
        x.style.outline = null;
        
        } else {
        
        x.blur();
        
        }

    }

}


<a href="javascript: defocus(this);">click here</a>

Thanks feherke

But there is an error saying :

Error: x.nodeName is undefined

Tested on Firefox 3

I'd have thought this:

if (x.tagName.lowerCase() == 'a') {

Hi

Then let us start from the beginning : what is x ?

Thanks Dan, but "x.tagName" returns "undefined"

Feherke, as you can see in the code above, x refers to 'this', as shown in the html bit.

<a href="javascript: defocus(this);">click here</a>

Hi

Oops. Sorry. Missed that. However, my doubt was correct : x is not a reference to an element.

The [tt]this[/tt] keyword is a reference to the currently activated element if it is used in its event handler.

<a href="#" onclick="defocus(this);return false">click here</a>

Then the condition will work with [tt]x.getAttribute('tag')[/tt], [tt]x.nodeName.toLowerCase()[/tt] and [tt]x.tagName.toLowerCase()[/tt]. ( Sorry for the typo. )
