javascript - 如何使用 ng-click 获取 DOM 元素

Question

我有一些元素，比如:

<button ng-click="weirdFunction()">Pretty Button</button>

Controller 中的功能:

$scope.weirdFunction = function(element) {
 console.log(element);
}

在控制台日志中我想接收这个 DOM 元素。我尝试通过多种方式做到这一点:

1. <button ng-click="weirdFunction()" ng-model="button">Pretty Button</button>

   $scope.weirdFunction = function() {
console.log($scope.button);
}

2. <button ng-click="weirdFunction(button)" ng-model="button">Pretty Button</button> $scope.weirdFunction = function(elem) {
console.log(elem);
}

3. <button ng-click="weirdFunction($element)">Pretty Button</button> $scope.weirdFunction = function(elem) {
console.log(elem);
}但所有的尝试都以失败告终。我哪里错了？如何获取点击的元素？

请尝试以下代码段。

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.weirdFunction = function(element) {
     console.log(element);
    }  
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<button ng-click="weirdFunction($event.currentTarget)">Pretty Button</button>
 </div>
