javascript读取txt文件一行一行的读到末尾

Question

才在网上找到了，自己写答案把<script language="javascript">var Document = external.menuArguments.document;
if(window.getSelection) 
{
alert(window.getSelection().toString());
}
else if(document.selection && document.selection.createRange) 
{
var text = Document.selection.createRange().text;
//Document.write(text);
var fso, f1, ts, s="";   
var ForReading = 1;   
    fso = new ActiveXObject("Scripting.FileSystemObject");   
ts = fso.OpenTextFile("c:\\testfile.txt",   ForReading);  
while (!ts.AtEndOfStream)   
        s+= ts.ReadLine(   );
Document.write(s); 
    ts.Close();
}</script>
