执行iptv_channel_list()后，网页内容不能刷新，不知何故，还请各位老大指教！
var page_number = 0;
function iptv_channel_list()
{
mpeg_open();
document.write("<table border=\"0\" width=\"270\" height=\"266\" cellpadding=\"0\" cellspacing=\"0\">");
document.write("<tr><td width=\"80\" height=\"23\"></td><td></td></tr>");
page_list = 9 * page_number;
for(i=page_list+1;i<=page_list+9;i=i+1)
{
if(i <= channel_amount)
{
document.write("<tr><td width=\"80\" height=\"27\"></td><td height=\"27\"><a href=\"javascript:iptv_show_mode()\" onfocus = \"javascript:iptv_play(\'"+ channel[i-1] +"\');\"><font color=\"#FFFFFF\">CHANNEL "+ i +"</font></a></td></tr>");
}
}
document.write("<table border=\"0\" width=\"252\" height=\"46\" cellpadding=\"0\" cellspacing=\"0\">");
document.write("<tr><td width=\"42\" height=\"10\"></td><td width=\"62\" height=\"10\"></td><td width=\"86\" height=\"10\" ></td><td width=\"62\" height=\"10\"></td></tr>");
document.write("<tr>");
document.write("<td width=\"42\" height=\"36\"></td>");
document.write("<td width=\"62\" height=\"36\"><a href=\"javascript:list_change(\'subtract\')\"><img border=\"0\" src=\"image/page_left.jpg\" width=\"62\" height=\"36\"></a></td>");
document.write("<td width=\"86\" height=\"36\"></td>");
document.write("<td width=\"62\" height=\"36\"><a href=\"javascript:list_change(\'add\')\"><img border=\"0\" src=\"image/page_right.jpg\" width=\"62\" height=\"36\"></a></td>");
document.write("</tr>");
document.write("</table>");
}
function list_change(order)
{
mpeg_open();
page = parseInt((channel_amount-1)/9);
if(order == "subtract")
page_number = page_number - 1;
if(order == "add")
page_number = page_number + 1;
if(page_number < 0)
page_number = page;
if(page_number > page)
page_number = 0;
iptv_channel_list();
}
