Detailed Description

This ViewHelper cycles through the specified values. This can be often used to specify CSS classes for example. Note: To achieve the "zebra class" effect in a loop you can also use the "iteration" argument of the for ViewHelper.

= Examples =

<f:for each="{0:1, 1:2, 2:3, 3:4}" as="foo"><f:cycle values="{0: 'foo', 1: 'bar', 2: 'baz'}" as="cycle">{cycle}</f:cycle></f:for> <output> foobarbazfoo </output>

f:for each="{0:1, 1:2, 2:3, 3:4}" as="foo"> <f:cycle values="{0: 'odd', 1: 'even'}" as="zebraClass"> {foo} </f:cycle> </f:for> <output>
