My current code is like this which alternates between showing every 2 then every 1 item inside loop. I want it to show every 3 then every 1 item.
I use Adonis JS template engine (Edge)
<div class="column">
@each( PRO in products )
<div>{{ PRO.id }}</div>
@if($loop.index % 3 !== 0 && $loop.index + 1 !== products.length)
</div>
<div class="column">
@endif
@endeach
</div>
Its current result is like this:
<div class="column">
<div>1</div>
<div>2</div>
</div>
<div class="column">
<div>3</div>
</div>
<div class="column">
<div>4</div>
<div>5</div>
</div>
and I want it to become like this:
<div class="column">
<div>1</div>
<div>2</div>
<div>3</div>
</div>
<div class="column">
<div>4</div>
</div>
<div class="column">
<div>5</div>
<div>6</div>
<div>7</div>
</div>
To get a 3-1-3-1...
pattern, I would reason about something like:
products
array which would prevent creating an extra empty column <div>
at the end as per my above logic.<div class="column">
@each(PRO in products)
<div>{{ PRO.id }}</div>
@if((($loop.index + 1) % 4 === 3 || ($loop.index + 1) % 4 === 0) && $loop.index + 1 !== products.length)
</div>
<div class="column">
@endif
@endeach
</div>
I have created a small snippet to test the above logic which you can refer to.
const products = Array.from({
length: 7
}, (_, index) => ({
id: index + 1
}));
const columns = [];
let column = [];
products.forEach((product, index) => {
column.push(product.id);
const newIndex = index + 1;
if (newIndex % 4 === 3 || newIndex % 4 === 0) {
columns.push(column);
column = [];
}
});
if (column.length > 0) {
columns.push(column);
}
console.log(columns);
.as-console-wrapper { max-height: 100% !important; top: 0; }
