Can jQuery AJAX Handle File Uploads with POST Requests?

jQuery Ajax File Upload: Exploring the Possibilities

Can ajax requests be leveraged to upload files using the POST method?

Initial Approach

The provided jQuery code snippet performs an ajax request with a POST method. However, file upload is not directly supported through standard AJAX.

Alternative Solution: FormData

With the introduction of XHR2, file upload can be supported through the FormData object. This object allows for the inclusion of file data within the request body.

Compatibility Considerations

FormData support varies across browsers, with versions for the following desktop browsers being required:

• IE 10
• Firefox 4.0
• Chrome 7
• Safari 5
• Opera 12

Data Part Inclusion

When using FormData, it is necessary to fill the data part of the ajax request with the FormData object. This ensures that the file data is included in the request body.
