Jqueryajax uploading files using Multipartfile in SPRINGMVC

For a form with a file upload, the background uses the SPRINGMVC encapsulated Multipartfile file to receive files, and you need to use asynchronous commit, and return the appropriate prompt information

Use jquery's form plug-in, which is jquery.form.js the plugin, and then use the plugin's Ajaxsubmit method;

1$ ("#pageForm"). Ajaxsubmit ({2Type: "POST",3URL: "Your action.html",4DataType: "JSON",5Successfunction(data) {6         if(data.msg== ' SUCCESS '){7 alert (success);8         }9         Else{Ten alert (data.msg); One         } A     } -});
