我有一个多年前写的网页，当我们尝试更新它以便在更现代的浏览器中使用时，它给了我一些问题。
我在Chrome中遇到的错误是“未捕获的TypeError：xml_map.namedRecordset不是函数”
这导致我们必须填充的选择框因为它似乎存在xml解析的问题。
选择框的javascript位于：
<script language="JScript">
$(function() {
var currentDate = new Date();
$('#datepicker1').datepicker({
inline: true,
showOtherMonths: true,
dayNamesMin: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],
dateFormat: 'dd/mm/yy'
});
$("#datepicker1").datepicker("setDate", "-30d");
});
$(function() {
var currentDate = new Date();
$('#datepicker2').datepicker({
inline: true,
showOtherMonths: true,
dayNamesMin: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],
dateFormat: 'dd/mm/yy'
});
$("#datepicker2").datepicker("setDate", currentDate);
});

XML数据岛（HTML中的XML标记）仅受Internet Explorer支持。甚至微软也从IE 10开始删除支持：https://msdn.microsoft.com/en-us/library/hh801224(v=vs.85).aspx
这显然是很久以前的一些旧代码。您在Chrome中收到此错误的原因是因为Chrome以及可能是所有现代浏览器都无法识别XML标记以及与之相关的所有功能。
对不起，但您必须重写此代码才能使用现代支持的方法。
