Let me take you to analyze its mystery.
[1. The most basic pop-up window code]
In fact, the code is very simple:

[Ctrl A Select all Note: If you need to introduce external Js, you need to refresh to execute it ] Because it is a piece of javascripts code , so they should be placed between the . are effective for some older browsers. In these old browsers, the code in the tag will not be displayed as text. Develop this good habit.
window.open ('page.html') is used to control the pop-up of a new window page.html. If page.html
is not in the same path as the main window, the path should be written in front, the absolute path (http Both ://) and relative paths (..
/) are acceptable.
You can use either single quotes or double quotes, just don’t mix them.
This piece of code can be added anywhere in the HTML, between and , and between . The earlier it is, the earlier it will be executed, especially if the page code is long. , and if you want the page to pop up earlier, put it as far forward as possible.
【2. Pop-up window after setting】
Let’s talk about the settings of pop-up window. Just add a little more to the code above.
Let’s customize the appearance, size, and pop-up position of this pop-up window to suit the specific conditions of the page.

[Ctrl A select all Note: If you need to introduce external Js, you need to refresh to execute ]
参数解释：
js脚本结束
【3、用函数控制弹出窗口】
下面是一个完整的代码。

[Ctrl+A 全选注:如需引入外部Js需刷新才能执行]

这里定义了一个函数openwin(),函数内容就是打开一个窗口。在调用它之前没有任何用途。
怎么调用呢？
方法一：浏览器读页面时弹出窗口；
方法二：浏览器离开页面时弹出窗口；
方法三：用一个连接调用：
打开一个窗口
注意：使用的“#”是虚连接。
方法四：用一个按钮调用：

【4、同时弹出2个窗口】
对源代码稍微改动一下：

[Ctrl+A 全选注:如需引入外部Js需刷新才能执行]

为避免弹出的2个窗口覆盖，用top和left控制一下弹出的位置不要相互覆盖即可
。最后用上面说过的四种方法调用即可。
注意：2个窗口的name(newwindows和newwindow2)不要相同，或者干脆全部为空。
OK？
【5、主窗口打开文件1.htm，同时弹出小窗口page.html】
如下代码加入主窗口区：

加入区：
open即可。
【6、弹出的窗口之定时关闭控制】
下面我们再对弹出的窗口进行一些控制，效果就更好了。如果我们再将一小段代码加入弹出的页面(注意是加入到page.html的HTML中，可不是主页面中，否则...)，让它10秒后自动关闭是不是更酷了？
首先，将如下代码加入page.html文件的区：

然后，再用这一句话代替page.html中原有的DY>这一句就可以了。(这一句话千万不要忘记写啊！这一句的作用是调用关闭窗口的代码，10秒钟后就自行关闭该窗口。)
【7、在弹出窗口中加上一个关闭按钮】

呵呵，现在更加完美了！
【8、内包含的弹出窗口-一个页面两个窗口】
上面的例子都包含两个窗口，一个是主窗口，另一个是弹出的小窗口。
通过下面的例子，你可以在一个页面内完成上面的效果。

[Ctrl+A 全选注:如需引入外部Js需刷新才能执行]

看看 OpenWindow.document.write()里面的代码不就是标准的HTML吗？只要按照格式写更多的行即可。千万注意多一个标签或少一个标签就会出现错误。记得用OpenWindow.document.close()结束啊。
【9、终极应用--弹出的窗口之Cookie控制】
回想一下，上面的弹出窗口虽然酷，但是有一点小毛病(沉浸在喜悦之中，一定没有发现吧？)比如你将上面的脚本放在一个需要频繁经过的页面里(例如首页)，那么每次刷新这个页面，窗口都会弹出一次，是不是非常烦人？:-( 有解决的办法吗？Yes! ;-) Follow me.
我们使用cookie来控制一下就可以了。
首先，将如下代码加入主页面HTML的区：

[Ctrl+A 全选注:如需引入外部Js需刷新才能执行]

然后，用（注意不是openwin而是loadpop啊！）
替换主页面中原有的这一句即可。你可以试着刷新一下这个页面或重新进
入该页面，窗口再也不会弹出了。真正的Pop-Only-Once！
写到这里弹出窗口的制作和应用技巧基本上算是完成了
