jQuery - disable and enable an anchor tag based on condition

Question

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

var status = $('#status').val(); //Not sure if it is a value/text
$('#addlink').on('click', function (e) {
    if (status == 'Registered') {
        e.preventDefault(); // prevent the default action of anchor tag
        return false;
    }
});
