file upload using portlet

[narma s，修改在8 年前。]

I have 5 portlets in my page. I have one portlet which uses upload functioanlity. Whenever I do the upload it refreshes the entire page, and all the other portlets get refreshed. How to perform the upload functionality only within a portlet and avoid refreshing other portlets while doing the upload?

Thanks

You'd have to use an ajaxy like solution. Any regular submit on the page will always result in a full page render.
