jQuery ajax文件上传，要发送的参数

Question

<form action="upload_file.php" method="post" enctype="multipart/form-data">

Above is the line for a form to upload a file using php.

If i use the form as I wrote above I can get the various properties of the file to be uploaded from upload_file.php page.

Using jquery $.post , how can I do the same thing in upload_file.php ?

I googled but can't find the exact snippet of code necessary here.

Uploading images using jquery's ajax methods is a pain, generally involving dynamically creating an iframe and submitting a form inside it. I usually use this plugin: http://plugins.jquery.com/project/jquery-upload

You can write some php to echo the uploaded image data as a json object, which you can access once the upload is complete through the plugin.
