親測必須將程式碼放在記事本中，改成html格式，在用IE執行（必須）
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <title></title> </head> <script language="JavaScript"> function TextStreamTest(fname,Addname,n){ var fso,f,ts,s; var ForRWA=0,ForReading=1,ForWriting=2,ForAppending=8; var TristateUseDefault=-2,TristateTrue=-1,TristateFalse=0; fso=new ActiveXObject("Scripting.FileSystemObject"); var s1=Addname.innerHTML; if(fname.value!=""){ f=fso.GetFile(fname.value); switch(n){ case 1:ForRWA=ForWriting;break; case 2:ForRWA=ForAppending;break; } if(n>0){ ts=f.OpenAsTextStream(ForRWA,TristateUseDefault); var s1=Addname.innerHTML; ts.Write(s1); s=ts.ReadLine(); ts.Close(); } ts=f.OpenAsTextStream(ForReading,TristateUseDefault); s=ts.ReadLine(); ts.Close(); } return(s); } function run(n){ document.form3.textarea1.innerHTML=TextStreamTest(document.form5.text1,document.form4.textarea2,n); } </script> <body> <table width="392" border="1"> <tr> <td height="24" colspan="2"> <form name="form5" method="post" action=""> 檔案路徑:<input name="text1" type="textfield" value="E:\ss.txt" size="40"> </form> </td> </tr> <tr> <td width="207" height="163"> <form name="form3" method="post" action=""> <textarea name="textarea1" cols="30" rows="10"></textarea> </form> </td> <td> <form name="form4" method="post" action=""> <textarea name="textarea2" rows="10"></textarea> </form> </td> </tr> <tr> <td height="28"> <form name="form1" method="post" action=""> <input type="button" name="Button" value="讀取" onclick="run(0)"> </form> </td> <td> <form name="form2" method="post" action=""> <input type="button" name="Submit2" value="寫入" onclick="run(1)"> <input type="button" name="Button" value="新增" onclick="run(2)"> </form> </td> </tr> </table> </body> </html>
