Reverse loop

Maybe you should tell us what you mean by 'reverse loop'.

Hi Math,

While I'm no legend I will try and explain a basic example of where I use a negative/reverse loop.

In a positive loop deleting items that are part of the iteration count will cause a iteration mismatch and could cause unintended results. When I delete items that are part of the iteration count I use a negative loop so the iteration count remains intact.

Take this code, if you run this it will delete all rows in table[0] that have a empty cell[0] of a row.

var myTable = app.documents[0].stories.everyItem().tables.everyItem().getElements();


for (var i = myTable[0].rows.length - 1; i >= 0; i--) {
    if (myTable[0].rows[i].cells[0].contents == "") {
        myTable[0].rows[i].remove();
        }
    }

This code, on the other hand may not delete all the empty rows because as a row is deleted it effectively leap frogs the next row as it's been promoted up the order.

var myTable = app.documents[0].stories.everyItem().tables.everyItem().getElements();


for (var i = 0; i <= myTable[0].rows.length - 1; i++) {
    if (myTable[0].rows[i].cells[0].contents == "") {
        myTable[0].rows[i].remove();
        }
    }

Try it out and see what happens. I hope this helps.
