$("#purchaser_contact").live('submit', function(){

  $.ajax({
    type: "POST",
    url: 'ajax/contactSearch.php',
    data: ({ fname: $("#fname").val(), lname: $("#lname").val(), city: $("#city").val(), state: $("#state").val() }),
    success: function(d) {
      var obj = JSON.parse( d );
      if(obj.result != 0){
        $("#contactSearch").remove();
        $("#button-wrapper").before('<div id="contactSearch">' + obj.result + '</div>');
        $("#contactSearch").slideToggle('slow');

        //return false from submit!!

  });   

});

I know there are other posts on this but I couldn't figure out how to apply them properly to my situation without making it messy.

How do I return false on the submit event to prevent the form from submitting if I'm within the $.ajax and success functions?

Thanks.
