Changing Multiple <td>'s Backgrounds

Today my boss asked me to prepare him a function that would change table cell's background when a link inside this cell is clicked, and all others cells to default background.

To achieve this I used:


Code:
function zmieniamy(idkomorki)
{
/* change all td's background white */
TD = document.getElementsByTagName('td');
for(i=0;i<TD.length;i++)
if(TD[i].name=='zmieniaj')
TD[i].style.background='white'
/* change the color that we want */
document.getElementById(idkomorki).style.background="pink";
}
Now that works only in IE and in Mozilla once I click a link inside a cell, then some other link - the first cell keeps its pink background.
