Alternate row colours again

[Peter Dawn <pe...@gmail.com>]

hi guys,

last week i got the alternate colours to work within my foreach
component with the help of Murray and Jesse, but I have run into the
same problem again.
now on another page, I have another foreach leap which displays a
table. now within this foreach loop i am already using a class tag
(class="ognl:rowClass") and hence i cannot use another class tag for
alternate colours (class="ognl:rowStyle"). i might try the bean method
but again i would need to use the class element which i have already
used up.

is there another way around. sorry guys for repeating the problem.

Don't forget that html does allow multiple classes to be assigned to
an element, so another way to solve it is to just construct a string
containing multiple class names in the method referenced by the class
binding.  You can still use the EvenOdd bean, but you must call next()
on it yourself, and insert the return value into your class string.

Hi Peter.

It looks like you are using some kind of variable called rowClass,
so in this case you could use two such variables. Something like:

class="ognl:(rowIndex % 2) == 0 ? rowClassEven : rowClassOdd"

where rowIndex is an int property passed to the Foreach index param.

Or you can do something similar in an additional "style" tag which
overrides the background colour of the class.

Cheers,
Nick.
