禁止屏蔽类：
1.禁止右键
<body oncontextmenu=return(false)>
2.禁止选择
<body onselectstart="return false">
3.禁止粘贴
<body onpaste="return false">
4.禁止直接访问 [必须框架内才行]
<script>
if (top == self)top.location.href = "page.htm";
</script>
5.禁止frame引用
<script>
if (top != self)top.location.href = "page.htm";
</script>
6.禁止功能键Shift,Alt,Ctrl
<script>function key(){
if(event.shiftKey) alert("Shift不允许使用!");} document.onkeydown=key; </script>
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>
常用特效类
1.主页遥控器
文件一.(t1.html)
<SCRIPT language="JavaScript">
window.open("t2.html","_blank","width=200","height=200","scroll=no");
</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();
</script>
3.鼠标放在连接上强行点击
<script>
function mClk2() {var source=event.srcElement;if (source.tagName=="A"){source.click();self.focus();}}
document.write("<div onmouseover=mClk2();>");
</script>
