If you add   jquery form min js  You can simply do this   lt script gt      myform   ajaxForm function response      alert response           this will register the AJAX for  lt form id  quot myform quot  action  quot some url quot  gt     and when you submit the form using  lt button type  quot submit quot  gt  or    myform   submit    then it will send your request and alert response  lt  script gt    NOTE  You could use simple    FORM   serialize   as suggested in post above  but that will not work for FILE INPUTS    ajaxForm   will
