框架中的“target”

target=_self
 This will load the page in the same frame as the caller.  表示在目前窗口或框架里打开链接（默认的） 

target=_parent
 This causes the page to load in the same frameset as the caller taking the place of any sub frames.  表示在父窗口或框架里打开链接 

target=_top
 This loads the resulting page into the full body of the current window eliminating any frames.  表示在顶层框架里打开新链接 

target=_blank
 This opens up a new window and loads the page in to it.  表示始终在不同的新窗口打开链接 

target=_new
 Opens a new window and the page loads in it, all other links using same target open in this window.

表示始终在同一个新窗口打开链接

Whats this all about?
这些都是些什么东西呢？

By assigning a name to a frame via the name attribute, authors can refer to it as the "target" of links defined by other elements.

通过name属性为一个框架命名，作者就可以查阅由其它元素所定义的链接“target”。

e.g. If my frame is called "80four", then to get a link to open in that frame the code would read:

举个例子来说，如果我的框架叫做“80four”，那么，在这个框架中打开链接的具体代码如下：

<a href="pagename.html" target="80four">link name</a>


Then pagename.html would open in the frame "80four".

此时，“pagename.html”将在“80four”框架中打开。
