If you want to submit the file using ajax, there are basically three ways
1. You can encapsulate your file with formdata, and then put in the ajax data.
2. You can use the jquery from plug-in to upload Wenjia directly.
3. You can convert local files into base64 format, and then submit them in the same way as ordinary text formats. Then convert base64 to an image on the server side.
