Using HTML5 to drag a file to a browser and upload and download the file, html5 is becoming more and more powerful. I will share with you the specific implementation code below, if you are interested, you can refer to the code written on the jsp page and the background is the tomcat server. Therefore, the page contains some java code. If you use other languages in the background, you can ignore it:
The Code is as follows:
<% @ Page language = "java" contentType = "text/html; charset = UTF-8"
PageEncoding = "UTF-8" %>
<% @ Page import = "java. io. *" %>
Upload and download files
<% // Java code to display files available for download on the server
File f = new File ("G: // defggg /");
File [] list = f. listFiles ();
For (int I = 0; I <list. length; ++ I ){
System. out. println (list [I]. getName ());
Out. print ("+ list [I]. getName () +" '> "+ list [I]. getName ()
+"
");
}
