如何从指令更改控制器中的作用域变量的值

Question

这是我的HTML

<div ng-repeat=" month in months track by $index" ng-hide="fromdate == '' || todate =='' ||option != 'Yearly'">

        <input class="toBeChecked" type="checkbox" ng-disabled="month.disabled" checker-directive>
        <label ng-bind="month.Name"></label>
    </div>

这是我的控制器

$scope.months = [
    { "disabled": "false", "Name": "January" },
    { "disabled": "false", "Name": "February" },
    { "disabled": "false", "Name": "March" },
    { "disabled": "false", "Name": "April" },
    { "disabled": "false", "Name": "May" },
    { "disabled": "false", "Name": "June" },
    { "disabled": "false", "Name": "July" },
    { "disabled": "false", "Name": "August" },
    { "disabled": "false", "Name": "September" },
    { "disabled": "false", "Name": "October" },
    { "disabled": "false", "Name": "November" },
    { "disabled": "false", "Name": "December" },
]

这是我的指示

app.directive('monthDirective', function () {

return {

    restrict: 'A',
           link: function (scope, elem) {

        var fromDate , toDate;
        scope.$watch('fromdate', function (newValue, oldValue) {
            fromDate = new Date(newValue);
            fromDate = moment(newValue, 'YYYY-MM-DD');
            console.log('newValue', newValue)
        });

        scope.$watch('todate', function (newValue, oldValue) {
            toDate = new Date(newValue);
            toDate = moment(newValue, 'YYYY-MM-DD');
            var range = moment.range(fromDate, toDate);

            range.by('months', function (moment) {

               var monthArray = moment.toArray('months');
                for (var i = 0; i <= scope.months.length; i++)
                {
                    var status = false;
                        if (i == monthArray[1]) {
                            status = true;
                        }

                    if(status)
                    {
                        // $('.toBeChecked').prop('disabled', false);
                        console.log('TrueStatus', scope.months.disabled)
                        scope.months.disabled = 'false'
                    }
                    else
                    {
                        //$('.toBeChecked').prop('disabled', true);
                        console.log('FalseStatus', scope.months.disabled)
                        scope.months.disabled = 'true'
                    }
                }

            });
        });
    }
}

}）

我想发送＆＃34; scope.months.disabled＆＃34;的值。从指令到前端＆＃34; ng-disabled =＆＃34; month.disabled＆＃34;＆＃34;并根据逻辑
