通过JQuery AJAX将Javascript数组传递给PHP

Question

$('#button').live('click', function () {
    values_array = [];
    $('.field').each(function () {
        values_array.push = $(this).val();
    });
    $.ajax({
        url: 'page.php',
        data: {
            array_a: values_array
        },
        type: 'POST',

        success: function (data) {
            $('#div').html(data);
        }
    });
});


//page.php
echo $_POST['array_a'] . "<br/>"; //The line break echos, but nothing else

A.) Do I need to iterate through each class with $.each in order to create a proper array, and

B.) Why doesn't php echo it?

Answer 1

Change:

values_array.push = $(this).val();

to:

values_array.push($(this).val());

That should do the trick :)

Answer 2

.push is a method which you have used like a property try instead

values_array = [];
   $('.field').each(function() {
      values_array.push($(this).val());
   });
