last modified date of a text file.

Hi,

Is it possible to know the last modified date of a text file in javascript.

Any help would be appreciated.

Thanks.
Fred.

Fred,

Javascript typically cannot access files on the clients machine.
Exception is the (crippled) javascriptsupport for input elements named
"FILE" in forms for uploadpurposes.

What is it excactly you want to accomplish?
If you are talking serverside you could maybe do a little simple scipting
(every serverside scriptinglanguage I know of supports this).

If you are talking clientside: I think: No.

Reason for this is that javascript can be executed by every weppage, so your
filesystem needs some protection for this.

Solution:
If you want a webpage to access the clients filesystem, use Java.
Remember that the client still must give his/her permission to such an
applet to do so!

Regards,
Erwin

Hi Erwin,

I want it server side. I would like to use this to know if new data are
available on the server since my last check, if true, I update the web page.

You can see the last modified date of a file on the server two ways

1 serverside code. that depends on the platform [asp, php, ...]

2 clientside code [here in javascript], read the headers:

var x = new ActiveXObject("Msxml2.XMLHTTP");
x.open("GET","http://my.org/robots.txt",false);
x.send();
document.write('<pre>'+
unescape(x.getAllResponseHeaders()).replace(/&/g,"&<br>"));

tested on ie6

How and whether this can be accomplished depends on the server that
you are using. However, your approach seems quite weird. If you have
server-side scripting available, why do you not just use that to embed
content generated from server-side data?

Maybe he is trying to include webpages on somebody else's server..
