Ajax Submission Form Minimalist posture

<script type= "Text/javascript" >    function submitform ()  {         var action_url = $ (' form[name= ' Form-oem-add "]). attr ( ' Action ');         var action_type = $ (' form[name= ') Form-oem-add "]). attr (' method ');         //var post_data =  $ (' form[name= ' Form-oem-add "]). Serialize ();         var post _data = new formdata ($ (' form[name= ' Form-oem-add "] ') [0]);         $.ajax ({            type: action_ Type.touppercase (),             url: action_ url,            data: post_data,//  Forms to submit &NBSP;&NBSP;&NBSP;&NBSP;&NBsp;       async: false,             cache: false,             contentType: false,             processdata: false,            success:  function  (msg)  {                 if  (msg.errorcode == 1)  {         &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;POPX (msg.errorMsg, 5);                 } else {                    &NBSP;&NBSP;POPX (' New success ',  5);                }             }        } );    }</script>

It is important to note that:

1. The three attributes in the form are integral
   <form name= "" action= "" method= "" >
   

2. 
   

When a file field does not exist in the form, you can use the serialization of jquery to package the data directly

var post_data = $ (' form[name= "Form-oem-add"] '). Serialize ()

When a file field exists in the form, you can use the HTML5 form data object to package the data

var post_data = new FormData ($ (' Form[name= "Form-oem-add"] ') [0])
