Flatpickr始终保存当前日期时间

Question

我在我的表单中使用Flatpickr命名为trigger_date：

.form-group
  = label f, :trigger_date, class: "control-label"
  = text_input f, :trigger_date, required: true, class: "form-control datetime-picker"

无论我选择哪个日期，表单都将始终提交当前日期和时间。这是我当前设置的Flatpickr：

const flatpickr = require("flatpickr");
const moment = require("moment");
const $this= $(this)
let defDate = moment().format()

const dateString = $this.val()
if (dateString != NaN && dateString != "NaN" && dateString != null && dateString != undefined && dateString.length > 0) {
    defDate = moment().format()
}

const picker = flatpickr($this[0], {
  enableTime: true,
  defaultDate: defDate,
  dateFormat: "Z",
  altInput: true,
  weekNumbers: true,
  minuteIncrement: 1
});
