I am trying to select values in a multiple select option box. When i run my current code below, no item is selected in the option box but when i do parseInt(value) it only selects just the first option.
When i console.log(selected), it returns 4,5. How can insert 4,5 into $("#edit-items") to make it select both values in the option box.
PS: Sorry for my english
JS
var selected = $(this).attr('data-items'); returns 4,5
items = parseInt(selected)
$("#edit-items").val([items]);
parseInt() will only parse the first integer from 4,5. If you want to get all the intgers as an array, split the string and call parseInt() on each array element.
items = selected.split(',').map(str => parseInt(str));
$("#edit-items").val(items);
