在将所有数组推入后如何清空数组推？

Question

我对push数组有问题，如何在数据库中第二次插入时清空该数组。所以发生在我的问题中的情况是

第一次插入是可以的，如果再次按下提交，日志将在数组中的推入数据之前显示多次插入，那么在再次提交后是否可以清空数组？

第一个插入项等效于 2个项目。

所以当我以相同的顺序再次插入

我有变量

var orderNumber;
var orders = [];
var menu;

我这里有插入功能。

    $(document).ajaxStop(function () {

    $('#add_to_cart').on('click', function() {

    var customer_id = $('#hidden_customer_id').val();

    swal({
    title: "Are you sure to submit this?",
    text: "Once inserted, you will not be able to edit the transaction!",
    icon: "warning",
    buttons: true,
    dangerMode: true,
    })
    .then((willInsert) => {


      if (willInsert) {

        $('.tbody_noun_chaining_order').children('tr').each(function() {
          $row = $(this);
          if ($row.hasClass('condimentParent')) {

            // store a previous menu to the orders array if exists.
            if (menu !== undefined) {
              orders.push(menu);
            }
            menu = {
              'total': $row.find('.total').text(),
              'name': $row.find('.parent_item').text(),
              'customer_id': customer_id,
              'condiments': {
                'Item': [],
                'Qty': [],
                'Total': []
              }
            };

          } else if ($row.hasClass('editCondiments')) {
            // row is a condiment, append elements to the previous "menu" variable
            menu.condiments.Item.push($row.find('.child_item').text());
            menu.condiments.Qty.push($row.find('.condiments_order_quantity').text());
            menu.condiments.Total.push($row.find('.total').text());
          }
        });
        if (menu) {
          orders.push(menu);
        }


        storeOrder(orders);

        $('.append_customer_noun_order_price').text('0.00');

        $('.total_amount').text('0.00');
        $('.rate_computation').text('0.00');



      } else {
        swal("Cancelled");
      }
    });

正如聊天中已经提到的那样，您的代码中目前缺少orders和menu变量的重置。

这将是您需要的一部分代码，将其插入if (willInsert) {条件后面：

var orders= [];
var menu= undefined;

在您的for循环中：

// store a previous menu to the orders array if exists.
if (menu) {
    orders.push(menu);
}
