Answer 1

报什么错？
如果departdate的格式是 2010-01-01的， 替换成 2010/01/01 试试

Answer 2

 var departdate = "2011/06/27";依然报错

Answer 3

既然是缺少对象,那你看看有没有id=dpDate 这样的元素, 或者找找是不是有多个id为dpDate的元素

Answer 4

 var departdate = "2011/06/27";
                 var day = new Date(Date.parse(departdate)).getDay();
                 switch(day)
                 {
                    case 0:day="Sundy";break;
                    case 1:day="Monday";break;
                    case 2:day="Tuesday";break;
                    case 3:day="Wednesday";break;
                    case 4:day="Thursday";break;
                    case 5:day="Friday";break;
                    case 6:day="Saturday";break;
                 }
alert(day);
这段代码没错。
估计是你的JQUERY文件引用有问题。

Answer 5

        $(document).ready(function(){
            $("#dpDate").change(function(){
                 var departdate = $("#dpDate").val();
                 var array = departdate.split(/\-|\//);
                 var date = new Date()
                 date.setFullYear(array[0])
                 date.setMonth(array[1]);
                 date.setDate(array[2]);
                 var day = date.getDay();
                 
                 switch(day)
                 {
                    case 0:day="Sundy";break;
                    case 1:day="Monday";break;
                    case 2:day="Tuesday";break;
                    case 3:day="Wednesday";break;
                    case 4:day="Thursday";break;
                    case 5:day="Friday";break;
                    case 6:day="Saturday";break;
                 }
                 $("#lbDay").html(day);
            });
        });
