Question

我正在使用角度日期选择器：

http://angular-ui.github.io/bootstrap/#/datepicker

目前，它被硬编码显示42天或6周。

我想知道如何在ui-bootstrap-0.13.1.js中覆盖（即角度装饰器）这个函数，以显示4周。

这是功能：

ctrl._refreshView = function() {
  var year = ctrl.activeDate.getFullYear(),
    month = ctrl.activeDate.getMonth(),
    firstDayOfMonth = new Date(year, month, 1),
    difference = ctrl.startingDay - firstDayOfMonth.getDay(),
    numDisplayedFromPreviousMonth = (difference > 0) ? 7 - difference : -difference,
    firstDate = new Date(firstDayOfMonth);

  if (numDisplayedFromPreviousMonth > 0) {
    firstDate.setDate(-numDisplayedFromPreviousMonth + 1);
  }

  // 42 is the number of days on a six-month calendar
  var days = getDates(firstDate, 42);
  for (var i = 0; i < 42; i++) {
    days[i] = angular.extend(ctrl.createDateObject(days[i], ctrl.formatDay), {
      secondary: days[i].getMonth() !== month,
      uid: scope.uniqueId + '-' + i
    });
  }

  scope.labels = new Array(7);
  for (var j = 0; j < 7; j++) {
    scope.labels[j] = {
      abbr: dateFilter(days[j].date, ctrl.formatDayHeader),
      full: dateFilter(days[j].date, 'EEEE')
    };
  }

  scope.title = dateFilter(ctrl.activeDate, ctrl.formatDayTitle);
  scope.rows = ctrl.split(days, 7);

  if (scope.showWeeks) {
    scope.weekNumbers = [];
    var thursdayIndex = (4 + 7 - ctrl.startingDay) % 7,
      numWeeks = scope.rows.length;
    for (var curWeek = 0; curWeek < numWeeks; curWeek++) {
      scope.weekNumbers.push(
        getISO8601WeekNumber(scope.rows[curWeek][thursdayIndex].date));
    }
  }
};

我已经尝试将42天硬编码到更小的东西，但它打破了日历计算。只是看看是否有人已经扩展过这个？

干杯

如果使用装饰器，您应该能够在包含旧链接函数的新编译函数中包装_refreshView。在ctrl._refreshView包装器中，您可以执行以下操作：

directive.compile = function() {
  return function(scope, element, attrs, ctrl) {
    link.apply(this, arguments);

    var _refreshView = ctrl._refreshView;
    ctrl._refreshView = function() {
      _refreshView.apply(this, arguments);
      removeAnySecondaryOnlyRows(scope.rows);
    };

    removeAnySecondaryOnlyRows(scope.rows);
  };
};

和

//Remove any rows that contain only 'secondary' dates (those from other months)
function removeAnySecondaryOnlyRows(rows) {
  for (var i = 0; i < rows.length; i++) {
    var row = rows[i],
      areAllSecondary = false;

    //check the first and the last cell's .secondary property
    areAllSecondary = row[0].secondary && row[(row.length - 1)].secondary;

    if (areAllSecondary) {
      rows.splice(i, 1);
      i--;
    }
  }
}

所有这些都是一个功能正常的代码段，包括一个自定义模板和一些用于隐藏＆＃39;二级＆＃39;天（来自不同月份的那些）：

＆＃13;

(function() {
  "use strict";

  angular.module('myApp', ['ui.bootstrap'])
    .config(['$provide', Decorate])
    .controller("MainController", ['$scope', MainController]);

  function Decorate($provide) {

    //fix for Datepicker 'day mode' to show only rows with days from the current month
    $provide.decorator('daypickerDirective', ['$delegate', daypickerDirectiveDecorator]);

    function daypickerDirectiveDecorator($delegate) {
      var directive = $delegate[0],
        link = directive.link;

      // custom html template:
      directive.templateUrl = "common/directives/uiBootstrapDatepickerDay.tpl.html";

      directive.compile = function() {
        return function(scope, element, attrs, ctrl) {
          link.apply(this, arguments);

          var _refreshView = ctrl._refreshView;
          ctrl._refreshView = function() {
            _refreshView.apply(this, arguments);
            removeAnySecondaryOnlyRows(scope.rows);
          };

          removeAnySecondaryOnlyRows(scope.rows);
        };
      };

      return $delegate;
    }

    //Remove any rows that contain only 'secondary' dates (those from other months)
    function removeAnySecondaryOnlyRows(rows) {
      for (var i = 0; i < rows.length; i++) {
        var row = rows[i],
          areAllSecondary = false;

        //check the first and the last cell's .secondary property
        areAllSecondary = row[0].secondary && row[(row.length - 1)].secondary;

        if (areAllSecondary) {
          rows.splice(i, 1);
          i--;
        }
      }
    }
  }

  function MainController($scope) {
    $scope.dt = new Date();
  }
})();

＆＃13;

好吧，我代表ADMdtp模块。它是纯粹的AngularJs dateTimePicker，具有禁用模式和其他大量的greate选项：

与ngModel完全同步，因此无需销毁或手动更新dateTimePicker。
高程范围选择器;根据需要制作尽可能多的dateTimePicker，再次无需销毁或手动更新每个dateTimePicker。
禁用模式;很容易就可以在周或月中禁用任何一天，就像所有周末一样。
在变化的日子过渡。（诅咒你可以在选项中禁用它）
获取完整日期详细信息，例如UNIX格式的日期，日期格式和年，月，日，小时和分钟，以及...全数据属性。
...

<adm-dtp ng-model="date" full-data="date_full" options="disabled:['2016/1/20', '!i&i+1', '15d+2']"></adm-dtp>
