isdir){SwiftDFSswiftdfs=newSwiftDFS();if(isdir){return

swiftdfs.renameDir(username+"/"+path,name);}else{return

swiftdfs.renameFile(username+"/"+path,name);}}四、步驟實現(xiàn)12在cn/edu/sict/cloud/storage/Web/StorageController.java添加如下代碼@RequestMapping("/updatefile")@ResponseBodypublicObjectupdatefile(HttpServletRequestrequest,HttpServletResponseresponse,Stringpath,Stringname,boolean

isDir){Useruser=getSessionUser(request);boolean

flag=storage.updatefile(user.getUsername(),path,name,isDir);return

newMessageBean(flag,flag?Constants.SUCCESS_7:(isDir?Constants.ERROR_4:Constants.ERROR_5));四、步驟實現(xiàn)13用戶選擇某一文件觸發(fā)單擊事件show()：functionshow(){varobjTable=document.getElementById("tab");for(vari=0;i<objTable.rows.length;i++){varcheckbox=objTable.rows[i].childNodes[1].childNodes[0].childNodes[5];if(checkbox.checked==true){document.getElementById("delete").style.display="block";document.getElementById("download").style.display="block";document.getElementById("rename").style.display="block";document.getElementById("move").style.display="block";document.getElementById("copy").style.display="block";document.getElementById("selectColumn").style.display="block";break;}else{document.getElementById("delete").style.display="none";document.getElementById("download").style.display="none";document.getElementById("rename").style.display="none";document.getElementById("move").style.display="none";document.getElementById("copy").style.display="none";document.getElementById("selectColumn").style.display="none";}}}四、步驟實現(xiàn)14為重命名按鈕添加單擊事件rename()，并在js中添加如下代碼:functionrenanme(){varnum=0;varobjTable=document.getElementById("tab");for(vary=0;y<objTable.rows.length;y++){varcheckbox=objTable.rows[y].childNodes[1].childNodes[0].childNodes[5];if(checkbox.checked==true){if(num<1){varrenamebox=checkbox.parentNode.parentNode.parentNode.childNodes[3].childNodes[2];varrenametxt=checkbox.parentNode.parentNode.parentNode.childNodes[3].childNodes[0];renametxt.style.display="none";renamebox.style.display="block";num+=1;}else{alert('不能同時重命名兩個或兩個以上文件');location.reload();break;}}}}四、步驟實現(xiàn)15在js中添加如下代碼，獲取用戶輸入的文件名、文件路徑，判斷是否為文件夾functionsure(){varobjTable=document.getElementById("tab");for(vary=0;y<objTable.rows.length;y++){varcheckbox=objTable.rows[y].childNodes[1].childNodes[0].childNodes[5];if(checkbox.checked==true){varchangename=checkbox.parentNode.parentNode.parentNode.childN
