请问这段代码能实现txt文件的读取吗？我应如何测试？谢谢
function read(readfile)
{ var file = Components.classes["@mozilla.org/file/local;1"] .createInstance(Components.interfaces.nsILocalFile); file.initWithPath(readfile); var is = Components.classes["@mozilla.org/network/file-input-stream;1"] .createInstance(Components.interfaces.nsIFileInputStream); is.init(file, 0x01, 00004, null); var sis = Components.classes["@mozilla.org/scriptableinputstream;1"] .createInstance(Components.interfaces.nsIScriptableInputStream); sis.init(is); var output = sis.read(sis.available()); alert(output); } read("C:\test.txt"); |

我把代码写成这样好像用firefox打开，控制台报错，这是怎么回事啊
<html> <body> <script> function read(readfile) { var file = Components.classes["@mozilla.org/file/local;1"] .createInstance(Components.interfaces.nsILocalFile); file.initWithPath(readfile); var is = Components.classes["@mozilla.org/network/file-input-stream;1"] .createInstance(Components.interfaces.nsIFileInputStream); is.init(file, 0x01, 00004, null); var sis = Components.classes["@mozilla.org/scriptableinputstream;1"] .createInstance(Components.interfaces.nsIScriptableInputStream); sis.init(is); var output = sis.read(sis.available()); alert(output); } read("C:\test.txt"); </script> </body> </html> |
