More questions about the following:
1) It says in logic tags reference:
id: "The name of a page scope JSP bean that will
contain the current element of the collection on each
iteration, if it is not null."
So, it means myList ArrayList should conform
to JavaBean routines, is that right? For example:
If I have a List4Js class, it has to have
getters/seters
for getting/setting ArrayLists:
ArrayList myList = List4J.getResultList();
And the elements of an ArrayList should be a bean too.
2) If I want to get a collection of arraylists, I can
use the <logic:iterate> tag as following:
<logic:iterate id="jsList" name="listForJavaScript"
indexId="idx">
<logic:iterate id="myBean" name="jsList"
indexId="index">
jsArray[<%=idx%>][<%=index%>] =
<%=myBean.getYourValue()%>;
</logic:iterate>
</logic:iterate>
Since JavaScript Array usually has the following form:
myArray = new Array("sample", 1);
Do I need to conform to the above routine to create an
JavaScript Array element in order to correctly display
the results?
