I am working on an ASP application but I get this error in IE 8:
我正在开发一个 ASP 应用程序，但在 IE 8 中出现此错误：
Message: Object doesn't support this property or method

This is my code:
这是我的代码：
$(function() {
Today = new Date;
Annee = Today.getFullYear() - 18 ; //this is a Line 216
PlageMois = Today.getMonth();
Jour = Today.getDate() ;
//maxDate: new Date(new Date.getFullYear(), 1-1, 1),
$( "#datepicker_Majeur" ).datepicker({
monthNamesShort: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug','Sep', 'Oct', 'Nov', 'Dec'],

maxDate: new Date(Annee, PlageMois, Jour),

Your code falls prey to The Horror of Implicit Globalsand so I suspect Todayis a global being created via a non-JavaScript mechanism that doesn't let you assign a Dateobject to it.
您的代码成为隐式全局变量的牺牲品，因此我怀疑Today是通过非 JavaScript 机制创建的全局变量，该机制不允许您为其分配Date对象。
You need to declare your local variables with the keyword var. I suspect that will resolve the problem you're having. E.g. (note the first four lines):
您需要使用关键字 声明局部变量var。我怀疑这将解决您遇到的问题。例如（注意前四行）：
$(function() {
var Today = new Date;
var Annee = Today.getFullYear() - 18 ; //this is a Line 216
var PlageMois = Today.getMonth();
var Jour = Today.getDate() ;
//maxDate: new Date(new Date.getFullYear(), 1-1, 1),
$( "#datepicker_Majeur" ).datepicker({
monthNamesShort: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug','Sep', 'Oct', 'Nov', 'Dec'],
dayNamesMin: ['Su','Mo','Tu','We','Th','Fr','Sa'],
dateFormat: 'mm/dd/yy',
//maxDate: new Date(1993, 1-1, 1),
maxDate: new Date(Annee, PlageMois, Jour),
showOn: "button",
buttonImage: "/images/img-calendar.gif",
buttonImageOnly: true
});
});
Side note: The overwhelming convention in JavaScript is for variables to start with a lower-case letter (todayrather than Today). Starting something with an upper-case character (Today) is usually only done for constructor functions(like Date).
旁注：JavaScript 中压倒性的约定是变量以小写字母（today而不是Today）开头。以大写字符 ( Today) 开头的内容通常仅用于构造函数（如Date）。
