you can try posting the question in developer forums & stack exchange with your current VF page code to get better response..
but, to give you some direction, it will be something like this..
using standard javascript :
document.getElementById('{!$Component.YourLinkID}').style.display ='none';
or with jQuery, you can use the hide function to hide you page elements..
