现在在一行中完成所有操作

var text = $('#selector option:selected').toArray().map(item => item.text).join();

it return like this:

// Return an array of the selected opion values
// select is an HTML select element
function GetSelectValues(select) {
  var result = [];
  var options = select && select.options;
  var opt;

  for (var i=0, iLen=options.length; i<iLen; i++) {
    opt = options[i];

    if (opt.selected) {
      result.push(opt.value || opt.text);
    }
  }
  return result;
}

pass this function your select box as like..

将此功能传递给您的选择框，就像..

var selectBox = document.getElementsById('fm_delivery_or_collection');
alert(GetSelectValues(selectBox ));

it will return the array of selected values

它将返回选定值的数组

By using Jquery

通过使用 Jquery

$('select#fm_delivery_or_collection').val()

the valfunction called from the selectwill return an array if its a multiple.

如果它是一个倍数，val则从 调用的函数select将返回一个数组。

Simply add this line of code:-

只需添加这行代码：-

var reciever= jQuery('#to_select option:selected').toArray().map(item => item.text).join();
/* alert(reciever); */
