jquery upload ui only one file
hello.
I'm using jquery ui upload.
I have 3 upload blocks ,each with his add file, remove ecc... , like the jquery upload ui example, but i have 3 of these block.
My goal is to permit to each block to upload only one file, if i add a file where there is another upload the old uploaded file must be removed and the new file uploaded must take his position.
is possible?
my idea is to clear the list of jquery ui upload before add the new file, in mode that i upload always my last file, but' i can't find any list in the js code , can you help.
thanks.
