Hi all,
I am currently working on a file upload function with struts.
The original upload function allows multiple file uploads, with JSP's html
form submitted to the action. the
uploadform uses dynamic properties, and the jsp file refers to them with formFile[0],
formFile[1] ...
Now I wanna it be able to upload unlimited amount of files, with a selection box
listing current "uploaded" file list
and a file selection box to the let user choose new files. And the user is free to
remove any prevoiusly "uploaded"
file. All the files are not write to the database until user presses submit button.
In this way, we gotta three different "modes" for the Action:
add - add the file to the list
remove - remove it from the list
submit - submit all files in the list
My questions:
1) Shall I implement the add/remove function with Javascript, which only operates on
the select box(filenames), or
+implement different operations in the UploadAction.
2) For the latter case, the sequence is: the user chooses a file -> click the add
button(which submits the form and set
+parameter action to "add") -> The Action's , and lateron return an ActionForward back
to the upload page.
3. If we only needs javascript, how do we retrieve all the datafiles based on their
filenames in the action.
Thank you!
