问题描述
我目前正在使用 directiveElement.data（$ ngModelController）来访问元素的 $ ngModelController ，如下例所示。
I'm currently using directiveElement.data("$ngModelController") to get access to the element's $ngModelController, as in the following example.
describe("directiveElement", function () {
it("should do something with ngModelController", inject(function($compile, $rootScope) {
var directiveElement = $compile("<input ng-model="myNgModel" customDirective type="text"></input>")($rootScope);
$rootScope.$digest();
var ngModelCtrl = directiveElement.data("$ngModelController");
ngModelCtrl.$modelValue = "12345";
// do rest of test
}));
});
但是，我想知道是否有更好的访问 $ ngModelController ，或者如果访问 $ ngModelController 是个坏主意？
However, I want to know if there is a better to access the $ngModelController, or if accessing the $ngModelController is a bad idea?
推荐答案
你也可以做 directiveElement.controller（'ngModel'）。
我当然认为有合理的测试理由可以解释为什么要对此进行处理，不过更常见的方法是通过表单处理它（例如。 ）
I certainly think there are legitimate testing reasons why you would want a handle on this, though the more common way is to get a handle on it through the form (eg. https://github.com/angular/angular.js/blob/master/test/ng/directive/formSpec.js)
