Answer 1

Try .map()

var a = $(".valsa .vals").map(function () {
    return [$(this).val()]
}).get();
alert(a);

Answer 2

You can get the select boxes with the following JQuery code.

var selectBoxList = $('select.yourClass');

After that you need to loop through all of these select boxes and get the selected option like so.

selectBoxList.each(function()
{
  var selectedOption = $(this).val();
});

Answer 3

试试这个

$("option:selected").map(function(){ return this.value }).get();

Answer 4

Try this:

var values = [];
$('#.valsa .vals').each(function(i, selected){
    values[i] = $(selected).attr('value');
});
