With jQuery, How Do I Intercept Hyperlink Click Events Temporarily?

var seed = "&seed=laptops";
$("a").live('click',function(){
    $(this).attr('href', $(this).attr('href')+seed);
});

You can bind a click event to all the anchor tags, like

$("a").click(function(){
    // write your code
});

If you want to do the default action then put a return true; at the end of this function.
