javascript 日期操作

1.javascript中日期的构造函数：

new Date("month dd,yyyy hh:mm:ss");
new Date("month dd,yyyy");
new Date(yyyy,mth,dd,hh,mm,ss);
new Date(yyyy,mth,dd);
new Date(ms);

2.测试：

 	document.write("
" + new Date("February 3,2009"));
        document.write("
" + new Date("February 3,2009 10:52:03"));
        document.write("
");
        document.write("
" + new Date(2009,1,3));
        document.write("
" + new Date(2009,1,3,10,52,03));
        document.write("
");
        document.write("
" + new Date(Date.parse("February 3,2009")));
        document.write("
" + new Date(Date.parse("February 3,2009 10:52:03")));
        document.write("
" + new Date(Date.parse(2009,1,3)));
        document.write("
" + new Date(Date.parse(2009,1,3,10,52,03)));
        document.write("
" + new Date(Date.parse("2009/02/03")));
        document.write("
");
        document.write("
" + new Date("2009/02/03"));
        document.write("
" + new Date("2009/02/03 11:12:13"));
        document.write("

        document.write("

        document.write("
