在角度材料中禁用使用日期选择器的特定日期
问题描述：
我试图禁用日历中的特定日期，因此用户无法选择有问题的日期 - 请参阅https://plnkr.co/edit/PwCLKWPQU0s3habxgUly?p=preview。在角度材料中禁用使用日期选择器的特定日期
这里唯一的问题是我只能在将值返回给过滤器时禁用一个日期，而在这种情况下，我想禁用两个示例日期。我也可以在return语句中硬编码这两个日期，但是对于我的实际项目，禁用日期数组是未知的。
这里是JS：
var bookedDates = [new Date(2016, 10, 25).toString(), new Date(2016, 10, 10).toString()];
$scope.onlyWeekendsPredicate = function (date) {
var day = date.getDate();
var month = date.getMonth();
var year = date.getFullYear();
var todaysDate = new Date (year, month, day).toString();
var confirmedBookingDates = [];
for (var n = 0; n <= bookedDates.length; n++) {
if (todaysDate != bookedDates[n]) {
confirmedBookingDates[n] = true;
}
return confirmedBookingDates[n];
}
};

如果你有bookedDates让说，从数据库返回到数组像你上面做，你可以使用$过滤器来处理订单。 Codepen

2天+周末alphagrim：
function filterBookings() {
return function(date, bookedDates) {
var day = date.getDay();
if(day === 1 || day === 2 || day === 3 || day === 4 || day === 5){
var sw = 0;
for(var i =0; i < (bookedDates.length); i++) {
if(date.toString().trim() === bookedDates[i].toString().trim()){
sw = 1;
}
}
if(sw==0){
return date.toString();
}
}
};

它的工作，你可以使用PHP变量动态停用的日期，你可以绑定这个值从数据库中获得动态输出。
为禁用日期，使用!==标志

嗨再次，感谢您的建议是的，我们将使用外部DB。我试过运行上面的代码，'filterBookings'无法识别？ –
你是如何包含它的？确保你在控制器中请求了$ filter，所以它在$ ctrl中注册了$ filter提供者。 – alphapilgrim
没错，设法解决了这个问题。不过，日历中没有显示'bookedDates'数组的第二个日期，尽管 –
