I need to post a form which includes personal details and I need to upload an attachment file also I need to achieve this using AJAX.
How can I upload a file using AJAX , I need to post the personal detail as well as upload a file at the same time using AJAX , how can I do this?
You can’t upload files with AJAX because you can’t do multi-part encoded requests – that’s a limitation of the XMLHttpRequest API.
Workarounds for this typically involve using an IFRAME that is the target of a form that handles the actual file upload as a separate sub-process to the overall form. The response loaded in the IFRAME then communicates back to the DOM in the parent/calling page with information about the uploaded file.
