余弦函數
1、前段時間看到的：
<script>
var parent_url = window.parent.location.href.toLowerCase();
var where = document.referrer.toLowerCase();
var self_url = document.location.href.toLowerCase();
if(where.indexOf("gov")>=0 || self_url == parent_url || where == "")
{
location.replace("about:blank");
}
</script>
2、剛剛不小心看到的：
function jc()
{
jc_list = ['res://C:\\Program%20Files\\Rising\\Rav\ ssafety.exe/PNG/123','res://D:\\Program%20Files\\Rising\\Rav\ ssafety.exe/PNG/123','res://E:\\Program%20Files\\Rising\\Rav\ ssafety.exe/PNG/123'];
for ( i= 0; i<jc_list.length; i++)
{
ischeck = 1;
x = new Image();
x.onerror = function()
{
ischeck = 0;
}
x.src = jc_list[i];
if (ischeck == 1)
return 1;
delete x;
}
return 0;
}
