Answer 1

尝试这个

var x = $("#datepickerid").datetimepicker('getDate');
    var todaydate = new Date();
    var todaydate1 = new Date(todaydate.getFullYear(), todaydate.getMonth(), todaydate.getDate(), 0, 0, 0, 0);
    if (x== todaydate1) {

$（ '＃subtractDate'）ATTR（ “无效”， “无效”）。 }

从

更改此行

 $('#subtractDate').attr("disabled",true);

到

$('#subtractDate').attr("disabled","disabled");

Answer 2

我尝试了您的代码here

此外，您可以尝试从此处添加迁移插件：http://jquery.com/download/ 迁移将帮助您使用jQuery＆gt; 1.9

的旧函数

它工作正常，可能是你使用的jQuery UI和jQuery版本不兼容，或者是其他东西弄乱了它

HTML：

function addDaysToDate() {
    var date2 = $('#datepicker').datepicker('getDate');

    var date2 = $('#datepicker').datepicker('getDate');
    date2.setDate(date2.getDate() - 1);
    $('#datepicker').datepicker('setDate', date2);
    $('#datepicker').change();
}

用于禁用的代码在Firefox中不起作用，但在chrome和IE中
