javascript读取txt文件一行一行的读到末尾

[小带鱼]

var fso, f1, ts, s;   
var ForReading = 1;   
fso = new ActiveXObject("Scripting.FileSystemObject");   
ts = fso.OpenTextFile("c:\\testfile.txt",   ForReading);   
if(没有到结尾){
s = ts.ReadLine();
Document.write(s);
}
ts.Close();

这里怎么做个遍历？就是如何判断是否到了结尾？

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>
