数据取得类

1.取得分辨率
＜script＞document.write("宽为"+screen.Width+"高为"+screen.Height)＜/script＞

2.取得地址栏

＜script＞document.write(self.location)＜/script＞

3.取得地址栏后参数

＜SCRIPT＞var add = top.location;
add = add.toString();
document.write (add.substring(add.indexOf("?")+1,add.length));
＜/SCRIPT＞

1.主页遥控器

文件一.(t1.html)

＜/SCRIPT＞
文件二.(t2.html)
＜SCRIPT language="JavaScript"＞
function op(add){if (window.opener){window.opener.document.location = add;}}
＜/SCRIPT＞
＜a href=# onClick="op('link1.html')"＞地址1 ＜/a＞＜br＞＜a href=# onClick="op('link2.html')"＞地址2 ＜/a＞＜br＞＜a href=# onClick="op('http://music.jx165.com')"＞地址3 ＜/a＞

2.只弹一次的窗口

＜script＞
function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length ＞ 0) {offset = document.cookie.indexOf(search)
if (offset != -1) {offset += search.length;end = document.cookie.indexOf(";", offset);
if (end == -1)end = document.cookie.length;returnvalue=unescape(document.cookie.substring(offset, end))}
}
return returnvalue;
}
function jx165ad(){
if (get_cookie('jx165ad')==''){
document.cookie="jx165ad=yes"
window.open("ad.html","_blank","width=200","height=200","scroll=no");
}
else {}
}
＜/script＞
＜body＞
＜script＞
jx165ad();
