当我尝试关闭 A ngular Bootstrap Modal在 Angular 1.5 组件中，它抛出 Error: $injector:unpr Unknown Provider .
如果我使用 Controller 而不是 Component，它工作正常。我错过了什么吗？
<!doctype html>
<html ng-app="app">

<h1>Angular Modal Demo</h1>
<my-content></my-content>
</body>
</html>
脚本
angular.module('app', ['ngAnimate', 'ui.bootstrap']);
angular.module('app')
.component('myContent', {
template: 'I am content! <button type="button" class="btn btn-default" ng-click="$ctrl.open()">Open Modal</button>',
controller: function ($uibModal) {
this.open = function () {
$uibModal.open({
template: '<my-modal></my-modal>'
});
};
}
});
angular.module('app')
.component('myModal', {
template: '<div class="modal-body">I am a modal! <button class="btn btn-warning" type="button" ng-click="$ctrl.close()">Close Modal</button></div>',
controller: function ($uibModalInstance) {
this.close = function () {
$uibModalInstance.dismiss('cancel');
};
}
});
最佳答案
我在使用 $uibModal 和 1.5 组件时遇到了同样的问题。解决问题我们需要使用 open 方法中使用的对象属性的 component 属性。
var modalInstance = $uibModal.open({
component: 'someComponentWithContent', //here name of component
resolve: {
user: function () {
return user; //example resolve
}
}
});
$uibModal 的文档说我们在组件中设置了以下属性:
close - A method that can be used to close a modal, passing a result. The result must be passed in this format: {$value: myResult}
dismiss - A method that can be used to dismiss a modal, passing a result. The result must be passed in this format: {$value: myRejectedResult}
modalInstance - The modal instance. This is the same $uibModalInstance injectable found when using controller.
resolve - An object of the modal resolve values. See UI Router resolves for details.
因此，我们需要在组件中使用 bindings 而不是使用依赖注入(inject)。
var someComponentWithContent={
bindings:{
modalInstance:"<",
resolve:"<"
},
controller:someComponentController,
template:"Some template"
};
最后一件事是如何在组件的 Controller 中使用它:
function someComponentController(){
//here example usage of dismiss
this.modalInstance.dismiss('cancel'); //this.modalInstance is $uibModalInstance
console.log(this.resolve); //here object with resolved params
}
