The forum is not a coding service. You need to show your attempts and we can comment on them.
Read the 'stickies' at the main site about homework assignments.
Note, JS cannot read a text file on a local computer (with the exception on only one browser)
The most common access to a text file is from an internet server using ajax code logic.

Probably because it only works on MSIE.
What browser and version are you using?
don't listen to people who don't know how to do things...
Code:
<!DOCTYPE html>
<html>
<head>
<title>reading file</title>
<script type="text/javascript">
var reader = new FileReader();
function readText(that){
if(that.files && that.files[0]){
var reader = new FileReader();
reader.onload = function (e) {
var output=e.target.result;
//process text to show only lines with "@":
output=output.split("\n").filter(/./.test, /\@/).join("\n");
document.getElementById('main').innerHTML= output;
};//end onload()
reader.readAsText(that.files[0]);
}//end if html5 filelist support
}
</script>
</head>
<body>
<input type="file" onchange='readText(this)' />
<div id="main"></div>
</body>
</html>

that is not allowed by any browser.
if you have the file on your server, next to an html file, then you can use simple ajax to grab the file's contents. search for a basic ajax demo for that code.
Thanks for the reply.. actually i have urgent req for it.. i will tell u the full scenrio..if der is another way plz tell me dat..
i am using unix server.my html script is located in /var/www/etc/html path and the file containing the names is also stored in the same place.. i want to read this file n store all the names in an dropdown combo box in my html page.. i got a code which reads frm an array and stores in dropdown box..i mixed dat code with ur code which reads each line frm the file n stores in the array..bt i need that the same file is read everytime wich contains the name wich has to be displayed in combo box..
If u have any code plz send me..i need it urgently..
in brief
1) read content of the file
2) store the content into array
3) read the array n store the content into combobox in html.
