代码如下: function ReportFileStatus(filespec) { var fso, s = filespec; fso = new ActiveXObject("Scripting.FileSystemObject"); if (fso.FileExists(filespec)) s += " exists."; else s += " doesn't exist."; return(s); }
采用客户端的 FileSystemObject 对象 例: 代码如下: function check() { var fso; fso = new ActiveXObject("Scripting.FileSystemObject"); if( fso.FileExists("c://testfile.txt")) { alert("Exists!"); } else { alert("not Exists!"); } }
