Getting the index of the current loop in Play! 2 Scala template

Question

In Play! 1, it was possible to get the current index inside a loop, with the following code:

#{list items:myItems, as: \'item\'}
    
Item ${item_in         


        

Answer 1

Yes, zipWithIndex is built-in feature fortunately there's more elegant way for using it:

@for((item, index) <- myItems.zipWithIndex) {
    
Item @index is @item
}

The index is 0-based, so if you want to start from 1 instead of 0 just add 1 to currently displayed index:

Item @{index+1} is @item

PS: Answering to your other question - no, there's no implicit indexes, _isFirst, _isLast properties, anyway you can write simple Scala conditions inside the loop, basing on the values of the zipped index (Int) and size of the list (Int as well).

@for((item, index) <- myItems.zipWithIndex) {
    

        Item @{index+1} is @item 

             @if(index == 0) { First element }
             @if(index == myItems.size-1) { Last element }
             @if(index % 2 == 0) { ODD } else { EVEN }
    
}
