disable an <a tag with javascript

I am doingn an application and i have a list of items for selection using:
<a href="javascript:additem('itemid')" ID="Xitemid">itemid</a>

in my javascript after processing my item, I am doing:
document.getElementById("Xitemid").disabled = true;

This lowlights the link, but it is still able to be clicked.

Can I disable the link so that it cannot be clicked without changing the href information? I can do that, but if I enable it, i will need to change the href info back.

thanks

What about :

document.getElementById("Xitemid").href = "javascript:void(0);";

sjklein42, an FYI, your response did not wrap in the box. I had to look at the source to see it.
I liked your solution. I did this:
<a href="javascript:{if (! this.disabled) {move('BOXED','3004230501','500')}}" ID="O3004230501">3004230501</a>

and for the javascript, I did this:

function move(type,order,qty){
document.getElementById("O"+order).disabled = true;

and it worked well.

I tried:
<a href="javascript:{if (! this.disabled) {move('BOXED',this,'500')}}" ID="O3004230501">3004230501</a>

and this
function move(type,this,qty){
this.disabled = true;

but it did not work, can you tell me why?

This should have been:
function move(type,obj,qty){
obj.disabled = true;

not sure if using "this" would cause a problem.
