这是来自论坛上的一个问题，问题要求多个不同的页面，在打开子页面时，要共用同一个窗口，并且子窗口不能刷新。这跟google音乐里面的添加音乐，然后播放的效果类似。因为在播放音乐的时候，如果子页面刷新了，那么音乐必须从头来播放，自然效果不尽人意。类似的情况也会出现在视频的网站上。
下面，我们使用简单的Javascript代码来实现这一功能。本代码在目前所有主流浏览器里测试通过。
下面，先创建一个测试主页面，Test1.htm
XML/XHTML 代码
<!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>
<script type="text/javascript">
function winOpen() {
window.open("winA.htm?music=From_Test1_" + (new Date()).toLocaleString(), "mxh", "width=600,height=300")
}
</script>
</head>
<body>
<input type="button" onclick="winOpen()" value="打开子窗口" />
</body>
</html>
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
function winOpen() {
window.open("winA.htm?music=From_Test1_" + (new Date()).toLocaleString(), "mxh", "width=600,height=300")
}
</script>
</head>
<body>
<input type="button" onclick="winOpen()" value="打开子窗口" />
</body>
</html>
接下来，创建WinA.htm
XML/XHTML 代码
<!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>Window A</title>
</head>
<body>
<h1>这里是Window A</h1>
<script type="text/javascript">
if (window.location.href == window.top.location.href) {
self.top.location.href = "winB.htm" + window.location.search
}
else {
window.parent.frames["mxh2"].setMusic(window.location.search.substr(1))
}
</script>
</body>
</html>
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Window A</title>
</head>
<body>
<h1>这里是Window A</h1>
<script type="text/javascript">
if (window.location.href == window.top.location.href) {
self.top.location.href = "winB.htm" + window.location.search
}
else {
window.parent.frames["mxh2"].setMusic(window.location.search.substr(1))
}
</script>
</body>
</html>
接下来是WinB.htm
XML/XHTML 代码
<!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>Window B</title>
</head>
<body>
<iframe name="mxh2" src="winC.htm" style="width:600px;height:400px;" frameborder="0"></iframe>
<iframe name="mxh" src="winD.htm" style='display:none'></iframe>
<script type="text/javascript">
alert("页面刷新检测器")
</script>
</body>
</html>
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Window B</title>
</head>
<body>
<iframe name="mxh2" src="winC.htm" style="width:600px;height:400px;" frameborder="0"></iframe>
<iframe name="mxh" src="winD.htm" style='display:none'></iframe>
<script type="text/javascript">
alert("页面刷新检测器")
</script>
</body>
</html>
WinC.htm
XML/XHTML 代码
<!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>Window C</title>
</head>
<body>
<div id="showContent">初始化的内容</div>
<script type="text/javascript">
function setMusic(str) {
document.getElementById("showContent").innerHTML += "<br/>" + str
}
</script>
</body>
</html>
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Window C</title>
</head>
<body>
<div id="showContent">初始化的内容</div>
<script type="text/javascript">
function setMusic(str) {
document.getElementById("showContent").innerHTML += "<br/>" + str
}
</script>
</body>
</html>
WinD.htm
XML/XHTML 代码
<!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>Window D</title>
</head>
<body>
<script type="text/javascript">
window.name = "mxh";
window.top.name = "";
window.top.focus();
</script>
</body>
</html>
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Window D</title>
</head>
<body>
<script type="text/javascript">
window.name = "mxh";
window.top.name = "";
window.top.focus();
</script>
</body>
</html>
然后可以创建多个测试用的页面Test2.htm
XML/XHTML 代码
<!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>
<script type="text/javascript">
function winOpen() {
window.open("winA.htm?music=From_Test2_" + (new Date()).toLocaleString(), "mxh", "width=600,height=300")
}
</script>
</head>
<body>
<input type="button" onclick="winOpen()" value="打开子窗口" />
</body>
</html>
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
function winOpen() {
window.open("winA.htm?music=From_Test2_" + (new Date()).toLocaleString(), "mxh", "width=600,height=300")
}
</script>
</head>
<body>
<input type="button" onclick="winOpen()" value="打开子窗口" />
</body>
</html>
在不同的窗口里，打开测试页面，则，都会将内容显示在Window B所在的主体窗口内。并且页面是不刷新的。其原理就是将新开的页面在隐藏的窗口里打开，然后取出来传递的参数，使用javascript来进行数据的传递。其中窗口WinD.htm中的脚本不能少，而且是很关键的地方。
