Javascript 只能輸入數值語法

<script>
function isNumberPressed(){
var isValidKey = false;
var intCode = window.event.keyCode;
if (intCode >= 48 && intCode <= 57) isValidKey = true; //0-9
if (intCode == 13) isValidKey = true; //13 enter
if (intCode == 32) isValidKey = true; //32 spacebar
window.event.returnValue = isValidKey;
}
</script>

<input type=text name=txt1 id=txt1 onkeypress="javascript:isNumberPressed();">

javascript select new Option 用法

var myselect=document.getElementById("channels");
myselect.options[myselect.length] = new Option("123", "1", "", (channel==36)?1:0);

new Option("標題","value",沒用""即可,selected)

rtorront 安裝過程

須先安裝兩各套件
libtorrent rtorrent
安裝過程中也需要一些輔助軟體
automake autoconf devscripts libtool libcppunit-dev
安裝步驟
# wget http://xxxxxxxxxxxxxxxxx/libtorrent-x.xx.x.tar.gz
# wget http://xxxxxxxxxxxxxxxxxxx/rtorrent-x.x.x.tar.gz
# tar -zxvf libtorrent-x.x.x.tar.gz
# tar -zxvf rtorrent-x.x.x.tar.gz
# cd libtorrent-x.x.x
# ./autogen.sh
# ./configure
# make
# make install
# cd ../rtorrent-x.x.x
# ./autogen.sh
# ./configure --with-xmlrpc-c
# make
# make install

安裝過程中需要先安裝XMLRPC-C

安裝完rtorrent並執行後若出現rtorrent: error while loading shared libraries: libtorrent.so.13: cannot open shared object file: No such file or directory訊息,可以試試看下面的處理方式:
就是先修改/etc/ld.so.conf，增加include /usr/local/lib 这一行。再运行ldconfig即可.

安裝完後需在家目錄(cd ~ 即可)新增.rtorrent.rc內容如下:

min_peers = 20
max_peers = 100
min_peers_seed = 5
max_peers_seed = 10
max_uploads = 10
download_rate = 0
upload_rate = 20
directory = /home/kin/filedownload/downloading
session = /home/kin/filedownload/session
port_range = 6881-6881
port_random = no
check_hash = yes
use_udp_trackers = yes
encryption = allow_incoming,enable_retry,prefer_plaintext
peer_exchange = yes
system.method.set_key = event.download.finished,move_complete,"execute=mv,-u,$d.get_base_path=,/home/kin/filedownload/downloads/;d.set_directory=/home/kin/filedownload/downloads/"
schedule = watch_directory,10,10,load_start=/home/kin/filedownload/torrent/*.torrent
schedule = tied_directory,10,10,start_tied=
schedule = untied_directory,10,10,close_untied=
system.method.set_key = event.download.inserted,delete_torrents,"d.delete_tied="
schedule = throttle_1,01:00:00,24:00:00,download_rate=50
schedule = throttle_2,15:00:00,24:00:00,upload_rate=20
encoding_list = UTF-8
dht = auto
dht_port = 6881
execute_nothrow=rm,/tmp/bt_scgi.socket
schedule = chmod,0,0,"execute=chmod,777,/tmp/bt_scgi.socket"
scgi_local = /tmp/bt_scgi.socket
# Enable the default ratio group.
ratio.enable=
# Change the limits, the defaults should be sufficient.
ratio.min.set=200
ratio.max.set=500
ratio.upload.set=5120M
# Changing the command triggered when the ratio is reached.
system.method.set = group.seeding.ratio.command, d.close=, d.erase=
network.send_buffer.size.set = 4M
network.receive_buffer.size.set = 16M
