目前我在控制器A上有一个联系人列表。当我点击其中一个联系人时,它会将联系信息广播到控制器B 和控制器B中的datepicker指令。 即可。这是有效的,但有更好的方法来更新datepicker指令的输入吗?
app.directive('datePickerDirective', [function () {
return {
restrict: 'AE',
require: 'ngModel',
scope: {
datepickerNgModel: '=',
datepickerId: '@'
},
templateUrl: 'Content/app/directives/templates/DatePicker.html',
link: function ($scope, element, attrs, ngModel) {
$scope.$watch(function () {
ngModel.$setViewValue($scope.datepickerNgModel);
return ngModel.$modelValue;
});
$scope.$on('data-from-component-a', function (event, data) {
$('#' + $scope.datepickerId).val(data.date);
})
}
}
}]);

我会避免在这里使用事件($broadcast
)。您可以使用一个处理组件数据的漂亮工厂来完成。您没有提供有关您的日期选择器和控制器的任何信息,因此我创建了一个抽象示例,为您提供基本处理。
<强>&GT;通过工厂在控制器之间共享数据 - demo fiddle
<div ng-controller="MyCtrl">
<button ng-click="publishData()">
Publish data
</button>
<button ng-click="resetData()">
Reset data
</button>
</div>
<div ng-controller="MyOtherCtrl">
<my-directive my-model="data.getData()"></my-directive>
</div>
var myApp = angular.module('myApp', []);
myApp.controller('MyCtrl', function($scope, myFactory) {
$scope.publishData = function() {
myFactory.publishData();
}
$scope.resetData = function() {
myFactory.resetData();
}
});
myApp.controller('MyOtherCtrl', function($scope, myFactory) {
$scope.data = myFactory;
});
myApp.directive('myDirective', function () {
return {
restrict: 'E',
template: '{{myModel}}',
scope: {
myModel: '='
},
link: function (scope, element, attrs) {
scope.$watch('myModel', function (newValue, oldValue) {
console.log(newValue);
// $('#' + $scope.datepickerId).val(newValue);
});
}
}
});
myApp.factory('myFactory', function() {
return {
contactInfo: '',
publishData: function() {
this.contactInfo = 'Sdfsdfsdf';
},
resetData: function() {
this.contactInfo = null;
},
getData: function () {
return this.contactInfo;
}
}
});
