Angular UI 日期选择器。从今天开始仅启用 5 天，周末除外

Question

我在我的项目中使用 Angular UI Bootstrap datepicker 指令。我有这个特定的需求，就像我需要从今天起只启用 5 天。如果是周末，我需要禁用它们并启用剩余的日子。例如，如果今天是星期五，我需要启用星期五、星期一、星期二、网络、星期四。我正在使用 dateDisabled 属性来实现这一点。问题是所有过去一个月的日期也都已启用。另外我认为我提出的解决方案并不优雅。下面是我的标记和代码。请帮助我。提前谢谢你。

 <input show-weeks="false" ng-click="vm.openDate()" name="quotedate" type="text" class="form-control" ng-model-options="{timezone:'UTC'}" uib-datepicker-popup="dd/MM/yyyy" ng-model="vm.quote.date" is-open="vm.quotedate.opened" datepicker-options="vm.dateOptions" required close-text="Close" readonly="true"/> 

vm.dateOptions = {
     dateDisabled: disabled,
     minDate: today            
};

function disabled(data) {
        var date = data.date,
            mode = data.mode;
        if (today.getDay() === 0 || today.getDay() === 6) {
            return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6 || date.getDate() > today.getDate() + 5 );
        }else if (today.getDay() === 1) {
            return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6 || date.getDate() > today.getDate() + 4 );
        }else {
            return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6 || date.getDate() > today.getDate() + 6 );
        }
}

您要查找的是 min-date、max-date 和 date-disabled 属性，as described in the docs。本例中的 date-disabled 函数是直接从文档中拉取的，为了限制可用的日期范围，只需将 min-date 属性设置为当前日期时间：

vm.dt = new Date();
vm.minDate = angular.copy(vm.dt);

...以及从现在起的 max-date 五天：

var fiveDaysFromNow = angular.copy(vm.dt);
fiveDaysFromNow.setDate(fiveDaysFromNow.getDate() + 5);
vm.maxDate = fiveDaysFromNow;

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerDemoCtrl', function ($scope) {
  
  var vm = this;
  
  function today() {
    vm.dt = new Date();
  }
  
  today(); 
  
  vm.opened = false;

  vm.openDatePopup = function() {
    vm.opened = true;
  };

  // Disable weekend selection
  vm.disabled = function(date, mode) {
    return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6);
  };
  
  vm.minDate = angular.copy(vm.dt);
  
  var fiveWeekdaysFromNow = angular.copy(vm.dt);
  fiveWeekdaysFromNow.setDate(fiveWeekdaysFromNow.getDate() + 7);
  vm.maxDate = fiveWeekdaysFromNow;

  vm.dateOptions = {
    formatYear: 'yy',
    startingDay: 0
  };

  vm.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd.MM.yyyy', 'shortDate'];
  vm.format = vm.formats[0];

});
