问题描述

我正在处理一个ASP应用程序，但我得到这个错误在IE 8：

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

消息：对象不支持此属性或方法

这是我的代码：

      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
    });
 });

推荐答案

您的代码受到 隐藏全域的恐怖 ，所以我怀疑今天是通过非JavaScript机制创建的全局，不允许您为其分配 Date 对象。

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.

您需要使用关键字 var 声明您的本地变量。我怀疑会解决你有的问题。例如。 （注意前四行）：

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
    });
});

旁注：JavaScript中的压倒性约定是变量以小写字母开头（今天而不是今天）。使用大写字符（ Today ）启动某个东西通常只对构造函数（例如 Date ）。

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).
