Does a f开发者_Go百科ileuploader can be done only with ajax and not with flash,jquery plugins or frames.
Is this possible??
No. You need some sort of server side code involved. JavaScript is client side and has no influence over what happens on the server.
Yes, it is possible. You must code the javascript by yourself, using XMLHTTPRequest and taking in account all the browser compatibility issue.
Of course you must write your server side code to manage the upload of the files. You must do this even with JQuery.
JQuery and other libraries are written to make the life of developer easy. Don't reinvent the wheel.
