Store a select array in a variable js

You can create a collection with $('select') and then use .map() to generate an array, and .get() to convert from a jQuery collection to a native array.

An example would look like this:

var values = $('select').get().map(function(select){
    return select.value;
});

I do not quite understand what you want but see if it helps:

var array = new Array();
$('select').each(function(index, el) {
  array.push($(el).val());
});
console.log(array);

If you want to get only the selected options:

var array = new Array();
$('select option:selected').each(function(index, el) {
  array.push($(el).val());
});
console.log(array);
