Answer 2

如果您无法将区域设置更改为 DD/MM/YYYY，您可以尝试对日期选择器绑定进行子类化并覆盖 _init 方法。您需要设置以下属性：

this._separatorFirst.value = '/';
this._separatorSecond.value = '/';
this.dayField = document.getAnonymousElementByAttribute(this, "anonid", "input-one");
this.monthField = document.getAnonymousElementByAttribute(this, "anonid", "input-two");
this.yearField = document.getAnonymousElementByAttribute(this, "anonid", "input-three");
this.yearField.parentNode.className = "datetimepicker-input-subbox datetimepicker-year";
this.yearField.size = 4;
this.yearField.maxLength = 4;
this.yearLeadingZero = true;
this.monthLeadingZero = true;
this.dayLeadingZero = true;
this._fieldAMPM.parentNode.collapsed = true;

还可以考虑提交增强请求以使用特性和/或属性覆盖格式。
