Am I missing something? My values don't get stored into my array

Question

Hi

I have this

 var selected = []
        $('#SelectBoxContainer .DDLs :selected').each(function (i, selected)
        {
            alert($(selected).val());
            selected[i] = $(selected).val();
        });

My alert is telling me that it is going through this loop and getting the select box values. Yet once everything is said and done there is nothing in my "selected" array.

Answer 1

you are opening and closing array and then doing some magic without result...

it's late, but var selected = [] $('#SelectBoxContainer .DDLs :selected').each <..code....> has no result really.

try making array and then: selected.put($('#SelectBoxContainer ))

in other words, you don't have ';' after 'var selected = []'

Answer 2

Your callback defines a local variable named selected, which hides the selected variable in the outer scope. The selected in selected[i] = is the selected from function (i, selected), not the selected from var selected.

Rename one of the two variables for this to work.

Answer 3

How do you expect to work with two variables named "selected" at the same time? Change the name of your function's second parameter so that it doesn't shadow the array you're trying to write to:

var selected = [];
$('#SelectBoxContainer .DDLs :selected').each(function (i, item)
{
    selected[i] = $(item).val();
});

You can also use the array push method instead of bothering with indices:

selected.push( $(item).val() )
