how to solve this simple problem in jstl ?

[Alvin chew]

hi, i currently facing the problem in jstl tag, i'm not sure what tag to use in order to tackle my problem

 <tr class="<%=i%2== 0?"odd":"even"%>"

if i have condition as above, which actually use to make different color in each row, can somebody recommend the way to solve this out ? thank you

<c:choose> comes to mind

You haven't given much context in which to help you, but I'll take a stab.

Assuming JSP 2.0, and that you are using something along the lines of the following to iterate over the collection you are using to build the table:

<c:forEach items="${theItems}" var="item" varStatus="loop">  

it should not look too different from what you already have:

<tr class="${((loop.index % 2) == 0) ? 'odd' : 'even'}">

If you are not using JSP 2.0, you'll need to follow Jeroen's suggestion of a combination of <c:choose> and <c:set> to set up a variable for the style class since the ternary operator (?) is not available in the JSTL 1.0 Expression Language.

thanks for reply, Bear Bibeault and Jeroen Wenting

<c:forEach var="record" items="${list}" varStatus="loop" >
 
 <tr bgcolor="${((loop.index % 2) = 0)? 'ffffff' : 'a1b39c' }" >

why in this case, my table didn't make the rows of record in different color, is there any mistake i done ?

the result given me he whole table with blue color

Have you checked the syntax of your HTML? Specifically the color values?

hi, Bear Bibeault , i try the following which give me same result(blue), all the row is in one color, but not interchange

<c:forEach var="record" items="${list}" varStatus="loop" >
 
<tr bgcolor="${((loop.index % 2) == 0)? '#FFFFFF' : '#FFDEAD' }" >

i'm using tomcat 5.5

What does the generated HTML look like?
