On page load, I am checking to see if a person is registered. If he is then, I will enable a link otherwise disable the link.

I tried the following , but it doesnt work.

Answer 1

Why don't you use the javascript:void(0) ?

 Link 

like

var href = 'javascript:void(0)';

var status = $('#status').val();  // ??
if (status == 'Registered'){
    href = 'available link';
}

$('#addlink').attr('href',href);
