如果页面过长而我们看到一半,这时我们刷新页面,要想在看刚刚内容我们需要在拉滚动条到刚才的位置,这样非常麻烦,以下这段代码将会解决你的烦恼,
< language="java">
Get (name)
{
var arg = name + "=";
var alen = arg.length;
var clen = .length;
var i = 0;
while (i < clen)
{
var j = i + alen;
if (.substring(i, j) == arg)
return getVal (j);
i = .indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
getVal (offset)
{
var endstr = .indexOf (";", offset);
if (endstr == -1)
endstr = .length;
return unescape(.substring(offset, endstr));
}
Set (name, )
{
= name + "=" + escape ()
}
</>
</head>
