问题
Before asking this question, I visited many other related ones and tried to gather the maximum of information. But, what I found till now let me understand that there is no real/major difference between ui:repeat
and h:dataTable
, and that whenever we can use h:dataTable
we can also use ui:repeat
(sometimes one of them is a little complex than the other, but at the end we got same results).
So, is there any use cases where the only choice is to use h:dataTable
? or the opposite (only choice is ui:repeat
)?
回答1:
is there any use cases where the only choice is to use h:dataTable?
- If you want to use an UIData-based component (with all of its special attributes absent in
UIRepeat
). - If you want to render a HTML
<table>
by a JSF component. - If you want to be able to customize the
<table>
rendering (like PrimeFaces<p:dataTable>
does with sorting, filtering, grouping, folding, lazyloading, etc, etc). - If you aren't using Facelets as view technology.
or the opposite (only choice is ui:repeat)?
- If you don't want any of above and thus need a pure markup-less iteration component.
- If you want to be able to skip every n items during iteration (using
step
attribute).
