我在一個表單中有 4 個選擇欄位。我的 jQuery 代碼只捕獲一個欄位。如何捕獲其他欄位并提取它們的值？
此外，我已經在所有這些領域應用了 Select2 插件。有人可以指導我嗎？提前致謝。
$('select').change(function() {
var optionSelected = $(this).find("option:selected");
var valueSelected = optionSelected.val();
var textSelected = optionSelected.text();
var csr = $("input[name=csrfmiddlewaretoken]").val();
console.log(textSelected);
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>

要獲取select可用于map()構建它們的陣列的所有元素的選定文本，如下所示：
let getSelectedText = () => {
let textArr = $selects.map((i, el) => $(el).find('option:selected').text()).get();
console.log(textArr);
}
let $selects = $('select').on('change', getSelectedText);<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>
