firefox 6.0, extension getfilesize, last modified time always return "2011.05.16 xxx", it seemed there is bug in XMLHTTP.getResponseHeader('Last-Modified') ?
file: chrome\content\load.js there is some bug, so firefox 4.0 can't run it correct. then i modify the source code as following:
function get_file_meta(url, callback, strings) {
XMLHTTP = new XMLHttpRequest();
XMLHTTP.open("HEAD", url, true);
XMLHTTP.url = url;
XMLHTTP.callback = callback;
XMLHTTP.strings = strings;
XMLHTTP.onreadystatechange = function()
{
if(XMLHTTP.url && 4 == XMLHTTP.readyState)
{
var size = XMLHTTP.getResponseHeader('Content-Length');
var stime = XMLHTTP.getResponseHeader('Last-Modified');
XMLHTTP.url = ;
var str_size = ;
var str_time = ;
if(size)
{
var strings = XMLHTTP.strings;
str_size = strings.getString("Size") + ': ' + format_size(size, strings) + (size > 1024 ? ' (' + size + ' ' + strings.getString("bytes") + ')' : );
var time_str = '-';
if(stime)
{
var t = new Date(stime);
time_str = t.toLocaleString();
}
str_time = strings.getString("Last modified") + ': ' + time_str;
}
XMLHTTP.callback(str_size, str_time);
