So I want to upload a file to the server using ajax, so the form is not submitted. Cffile requres the filefield attribute, but as there is no form object passed to coldfusion that doesn't work. I can store the value entered by the user as a variable in javascript, and pass that variable to cf. How can I use this variable to upload my file? Thanks.

提交表单到一个隐藏的iframe和处理表单的上传，你通常会。

Submit the form to a hidden iframe and handle your form upload as you normally would.
