我正在尝试在Angular指令中注入
这是我的指令:
为什么无法解决? 我尝试了以下方法:
ngModel
,但出现以下错误:Error: [$injector:unpr] Unknown provider: ngModelProvider <- ngModel

这是我的指令:
module.directive("myDatePicker", function () {
return {
restrict: "A",
template: '<p class="input-group" title="{{title}}">' +
'<input type="text" class="form-control" data-datepicker-popup="{{dateFormat}}" ng-model="selectedDate" data-is-open="isOpen" data-datepicker-options="dateOptions" ng-required="true" data-close-text="{{closeText}}" />' +
'<span class="input-group-btn">' +
'<button type="button" class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>' +
'</span>' +
'</p>',
replace: true,
require: '?ngModel',
//priority: 0,
scope: {
title: "@",
selectedDate: "=ngModel",
onChange: "&",
dateFormat: "="
},
compile: function (tElement, tAttrs, transclude) {
// Correct ngModel for isolate scope
if (tAttrs.ngModel) {
tAttrs.$set('selectedDate', tAttrs.ngModel, false);
tAttrs.$set('ngModel', 'selectedDate', false);
}
return {
post: function (scope, iElement, iAttrs, controller) {
// Render
return controller.$render = function () {
if (!controller.$viewValue) {
return;
}
angular.extend(scope, controller.$viewValue);
};
}
};
},
priority: 100,
link: function (scope, elem, attr) {
},
controller: function ($scope, global, ngModel) {
$scope.isOpen = false;
$scope.closeText = 'Close';
$scope.dateOptions = {};
$scope.open = function ($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.isOpen = true;
};
$scope.$watch(function () {
return $scope.selectedDate;
},
function (newValue, oldValue) {
ngModel.$setValidity('required', newValue == true);
$scope.onChange({ newDate: newValue, oldDate: oldValue });
}, true);
}
};
});
这是我的HTML代码:
<input data-my-date-picker
id="EventDatePicker" data-name="EventDatePicker"
data-date-format="dateFormat"
ng-model="EventDetails.Date"
ng-required="true"
data-title="Date" />
为什么无法解决? 我尝试了以下方法:
module.directive("myDatePicker", ['ngModel', function () {
我尝试了一些解决方案,但都没有用。
我也尝试了删除priority
,但是仍然没有用。
这与指令加载的顺序有关吗?
我错过了什么吗?
有什么想法吗?
最后,根据sma的建议,我做了这个:
require: ['^ngModel'/*, '^isDate'*/],
scope: {
title: "@?",
name: "@?"
},
link: function (scope, elem, attr, ngModel/*, isDate*/) {
...
这似乎有点奏效。
我不确定为什么我无法在控制器中注入它。 :(
一定有办法,但我还没有找到...
但出于某种奇怪的原因,像上面的isDate
这样的指令仍然没有被注入(尽管它们在当前指令之前定义)。
这很令人困惑。
require
而不是requires
