jQuery validation conflicting with AJAX call -


i've got form pretty simple validation snippet simple ajax call, except when try put 2 i'm running problems. if put validation snippet ahead of ajax call validation works ajax call not submit. if put ajax call ahead of validation ajax call works , validation doesn't. i'm lost , been banging head hours on one. appreciated!

$("#headerform").submit(function(){      var validate = true;           $("#headerform :input").each(function(){                            var $this = $(this);                                    if(this.id == "phonenumber" && $this.val().length < 10 ){                  alert("please enter valid phone number");             validate = false;             return false;                 } else if(!this.value.length){                        alert("field required");             validate = false;             return false;           }                });     return validate;  var name = $("#name").val();     var phone = $("#phone").val();      var datastring = 'name='+ name + '&phone=' + phone;       $.ajax({         type: "post",         url: "/bin/headerform",         data: datastring,         success: function() {           $('#headerform').html("<div id='message'>thank you</div>");         }       });       return false;   });

the best practice move validation code function, call in submit handler:

function validateform() {     var validate = true;     $("#headerform :input").each(function () {         var $this = $(this);         if (this.id == "phonenumber" && $this.val().length < 10) {             alert("please enter valid phone number");             validate = false;             return false;         } else if (!this.value.length) {             alert("field required");             validate = false;             return false;         }     });     return validate; }

then submit handler:

$("#headerform").submit(function () {      if (validateform()) {         var name = $("#name").val();         var phone = $("#phone").val();          var datastring = 'name=' + name + '&phone=' + phone;          $.ajax({             type: "post",             url: "/bin/headerform",             data: datastring,             success: function () {                 $('#headerform').html("<div id='message'>thank you</div>");             }         });     }     return false; });
