使用ajax提交表单时出错

由于某种原因，表单没有被提交。我已经使用ajax表单保存表单的详细信息在我的数据库。

网站链接如下:http://www.famproperties.com/mudon/Abu-Dhabi/villas.html

脚本代码如下:

   <script>
$(document).ready(function() {
    $("#submit-form-button").click(function() { submitForm(); });
});
function submitForm() {
    if ( $("#NAME").val() == '' ||
  $("#EMAIL").val()  == '' ||
  $("#MOBILE").val()   == '' ||
  $("#NOTE").val() == '' )
  { alert ("All field are required");}
else {
     $.ajax({
      type: "POST",
      url: "http://famproperties.com/real_estate/property/contact/lead/",
      data: {  
   NAME:   $("#NAME").val(), 
   EMAIL:  $("#EMAIL").val(), 
   MOBILE: $("#MOBILE").val(), 
   NOTE:   $("#NOTE").val(),
   SOURCE: 'MSB.COM'
   },
      success: function() {
         alert("Thanks, Our specialist will contact you soon.");
      },
      dataType: 'html'
    });
  $("#NAME").val(''); 
  $("#EMAIL").val(''); 
  $("#MOBILE").val(''); 
  $("#NOTE").val('');
}};
</script>

这是表单代码。
