Question

I have the following code

    var select1 = document.getElementById(\"airports-select-1\");
    var selected1 = [];
    while(select1         


        

Answer 1

Another approach for those who like a more functional style:

selections = Array.from(selectBox.options).filter(o => o.selected).map(o => o.value)

or

selections = Array.from(selectBox.selectedOptions).map(o => o.value)
