Formdata Uploading Files

The selected XML needs to be uploaded to the background, converted to htmlhtml via XSLT:  <form id= "Uploadform" enctype= "Multipart/form-data" >   <input Type= "File" Name= "testfile" value= "Select File" >   <input type= "button" value= "Add" id= "BTN" >  </form> Js:<script type= "Text/javascript" >    var formData = new FormData ($ ("#uploadForm") [0]);          $.ajax ({               url:url,               type: ' POST ',               data:formdata,               async:false,               cache:false,               contentType: False,               Processdata:false,               success:function (data) {        ...             },               error:function (returndata) {                   alert ("Error");}          );   </script>

　　

Here are a few things to note:

• processDataSet to false . Because the data value is an FormData object, you do not need to process the data.
• <form>tag to add a enctype="multipart/form-data" property.
• cacheSet to false , the upload file does not need to be cached.
• contentTypeSet to false . This is set to false because it is an <form> object constructed by a form, and the FormData property has already been declared enctype="multipart/form-data" .

After uploading, the server-side code needs to use the file get file input stream object from the query parameter name, because <input> it is declared in name="file" .
