public class ArraySubsetHelper
This droplet determines the indices of a corresponding array if the array was subdivided into separate parts. It was designed with the display of product ranges in mind. It allows the user to display a numerical navigation through the subsets of a given array.
This droplet takes the following input parameters:
This droplet renders the following oparams:
This droplet sets the following output parameters:
This droplet assumes the base index starts at 1. Those who wish this to start
at zero should set the startIndexAtZero
value to true.
Example:
<dsp:droplet bean="/atg/store/droplet/ArraySubsetHelper"> <dsp:param name="array" param="category.childProducts"> <dsp:param name="elementName" value="subsetIndex"> <dsp:param name="subsetSize" value="10"> <dsp:oparam name="output"> <dsp:droplet name="ForEach"> <dsp:param name="array" param="subsetIndices"> <dsp:oparam name="output"> <dsp:valueof param="count"/> <dsp:valueof param="subsetIndex"/> </dsp:oparam> </dsp:oparam> </dsp:droplet>
