href：获取或者设置document的地址信息；
hostname：获取或者设置document的主机名；
search：获取或者设置document url查询部分的信息；
hash：获取或者设置document url hash部分的信息；
assign(<url>)：导航到一个指定url；
replace(<url>)：移除当前document，导航到指定的url；
reload()：重新加载当前document；
resolveURL(<url>)：将相对路径变为绝对路径。
来看下面的例子：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<script type="text/javascript">
document.writeln('<pre>');
document.writeln('protocol:' + document.location.protocol);
document.writeln('host:' + document.location.host);
document.writeln('hostname:' + document.location.hostname);
document.writeln('port:' + document.location.port);
document.writeln('pathname:' + document.location.pathname);
document.writeln('search:' + document.location.search);
document.writeln('hash:' + document.location.hash);
document.writeln('</pre>');
</script>
</body>
</html>
结果：
4.读写cookie
通过cookie属性，可以对document的cookie进行新增，修改和读取操作。如下例：
<!DOCTYPE HTML>
<html>
<head>
<title>Example</title>
<meta name="author" content="Adam Freeman" />
<meta name="description" content="A simple example" />
</head>
<body>
<p id="cookiedata">
</p>
<button id="write">
Add Cookie</button>
<button id="update">
Update Cookie</button>
<button id="clear">
Clear Cookie</button>
<script type="text/javascript">
var cookieCount = 0;
document.getElementById('update').onclick = updateCookie;
document.getElementById('write').onclick = createCookie;
document.getElementById('clear').onclick = clearCookie;
readCookies();
function readCookies() {
document.getElementById('cookiedata').innerHTML = !document.cookie ? '' : document.cookie;
}
function updateCookie() {
document.cookie = 'cookie_' + cookieCount + '=update_' + cookieCount;
readCookies();
}
function createCookie() {
cookieCount++;
document.cookie = 'cookie_' + cookieCount + '=value_' + cookieCount;
readCookies();
}
function clearCookie() {
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var arrStr = document.cookie.split("; ");
for (var i = 0; i < arrStr.length; i++) {
var temp = arrStr[i].split("=");
if (temp[0]) {
document.cookie = temp[0] + "=;expires=" + exp.toGMTString();
};
}
cookieCount = 0;
readCookies();
}
</script>
</body>
</html>
