[英]JSP syntax for an empty custom tag?
What is the proper way of creating an empty custom tag in JSP? 在JSP中创建空的定制标记的正确方法是什么?
Is should have a prefix and suffix. 是应该有一个前缀和后缀。 An example would be TWONG prefix and GLOOP as suffix. 一个示例是TWONG前缀和GLOOP作为后缀。 Which choices are valid? 哪些选择有效?
a) <TWONG:GLOOP/>
b) <GLOOP:TWONG/>
c) <TWONG:GLOOP><TWONG:GLOOP/>
d) <GLOOP:TWONG><GLOOP:TWONG/>
A quick google search of "Empty custom tag in JSP" revealed zetcode.com: Custom JSP tags . 谷歌对“ JSP中的空自定义标签”的快速搜索显示了zetcode.com:自定义JSP标签 。
Their first code sample has the following in it: 他们的第一个代码示例包含以下内容:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="d" uri="http://zetcode.com/tlds/date" %>
<html>
...
<body>
<h2>Date</h2>
<b>Today's Date: </b> <d:DateTag />
</body>
The relevant items I see in there are taglib prefix="d"
and <d:DateTag />
. 我在其中看到的相关项目是taglib prefix="d"
和<d:DateTag />
。
Since d
is the prefix, I would assume the option of <PREFIX:SUFFIX/>
is correct. 由于d
是前缀,因此我认为<PREFIX:SUFFIX/>
的选项是正确的。
So, option a. 因此,选项a。 <TWONG:GLOOP/>
