在Angular Material中使用日期选择器禁用特定日期

Question

I'm trying to disable specific dates in a calendar so a user can't select the dates in question - please see https://plnkr.co/edit/PwCLKWPQU0s3habxgUly?p=preview . 我正在尝试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 。

The only issue here is that I can only disable one date when returning the value to the filter, whereas in this case there are two example dates I was wanting to disable. 这里唯一的问题是，当将值返回到过滤器时，我只能禁用一个日期，而在这种情况下，我想禁用两个示例日期。 I can also hard-code the two dates in the return statement, yet for my actual project the array of disabled dates is unknown. 我还可以在return语句中对这两个日期进行硬编码，但是对于我的实际项目，禁用日期的数组是未知的。

Here is the JS: 这是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];
    }

};

Answer 1

If you have the bookedDates let say from a DB returned into array like you do above you can use a $filter to handle bookings. 如果您有bookedDates的话，可以像上面一样从数据库返回到数组，则可以使用$ filter来处理预订。 Codepen Codepen

//Update, insert new predicate func.
$scope.onlyWeekendsPredicate = function(date) {
  return bookedDates.indexOf(date.toString()) === -1;
};

Its working, you can use php variable for dynamically disable the dates, you can bind this value from database to get dynamic output. 它的工作原理是，您可以使用php变量动态禁用日期，也可以从数据库绑定此值以获取动态输出。

for disable date, use !== sign 对于禁用日期，请使用!==号

        var sw = 0;
          for(var i =0; i < (bookedDates.length); i++) {
              if(date.toString().trim() === bookedDates[i].toString().trim()){
                sw = 1;
              }
          }
