I am working on an ASP application but I get this error in IE 8:

Message: Object doesn't support this property or method

Line: 216

Char: 8

Code: 0

This is my code:

$(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'],
           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
    });
 });

• Are the parentheses optional after new Date? – Martin Smith Commented Oct 16, 2013 at 7:36
• Give a try with "new Date()" instead of "new Date" – Jeyan Commented Oct 16, 2013 at 7:36
• @MartinSmith: Yes, amazingly, they are. – T.J. Crowder Commented Oct 16, 2013 at 7:37
• 1 @noboundaries: When calling a constructor function via new, if you have no arguments for it, the () are optional. Ref: ecma-international/ecma-262/5.1/#sec-11.2.2 – T.J. Crowder Commented Oct 16, 2013 at 7:37
• @T.J.Crowder - Thanks. Didn't look right without them to me! – Martin Smith Commented Oct 16, 2013 at 7:38

Your code falls prey to The Horror of Implicit Globals and so I suspect Today is a global being created via a non-JavaScript mechanism that doesn't let you assign a Date object to it.

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):

$(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 (today rather than Today). Starting something with an upper-case character (Today) is usually only done for constructor functions (like Date).
