- <b>Accessing properites</b>
+ <b>String Attributes</b>
</p>
<p>
- On the OGNL demo you learned how to access values from the Value Stack
using OGNL expressions.
- The <i>property</i> tag is used to print to the page, the result of an
OGNL expression. The expression
- is specified in the <i>value</i> attribute.
+ Some tag attributes are expected to be Strings in which case String
literals
+ can be passed as the value, like the <i>href</i> attribute in the <i>a</i>
tag.
</p>
-<p>To print the value of the expression <i>name</i> to the page type:
<p>
- <i id="example">
- <s:property value="name" />
+ <i>
+ <s:a href="http://struts.apache.org/" />
</i>
</p>
<p>
- on the JSP console and hit enter. <a href="#" onclick="evalJSP()">Do it
for me</a>
+ If the value that you want to use in one of these string literal
attributes, is stored on the Value Stack,
+ then the <i>%{#name}</i> syntax (alternative syntax) needs to be used.
Assuming there is a value
+ with the name "url" stored on the stack:
+</p>
+<p>
+ <i>
+ <s:a href="%{#url}" />
+ </i>
+</p>
+<p>
+ will create an anchor and use the value of "url" for the <i>href</i>
attribute.
+</p>
+<p>
+ <b>Value Attributes</b>
+</p>
+<p>
+ Other attributes expect an object as their value(not an string literal).
In these attributes you can specify
+ the name of a variable stored on the Value Stack, and the tag will look it
up and use it. Like the
+ <i>value</i> attribute in the <i>property</i> tag. Assuming there is an
object stored on the Value Stack with
+ the name "movie", then:
+</p>
+<p>
+ <i>
+ <s:property value="movie" />
+ </i>
+</p>
+<p>
+ will print the value to the page. To pass an String literal to an attribute
that expects a value use the <i>%{'string'}</i>
+ notation.
+</p>
+<p>
+ If you don't remember if an attribute expects an string literal or a value,
you can always use the <i>%{value}</i> notation:
+</p>
+<p>
+ <i>
+ <s:a href="%{'http://struts.apache.org/'}" />
+ <br />
+ <s:property value="%{#movie}" />
+ </i>
