我已经在我的文件中集成了一个圆环图。我想要甜甜圈的每个切片上的点击事件。我不知道如何进行点击事件。这是我的代码

<!DOCTYPE html>
<html ng-app="MyApp" >
<head>
<meta charset="utf-8">
<link href='https://fonts.googleapis.com/css?family=Roboto:400,300,500,700' rel='stylesheet' type='text/css'>

<body ng-controller="MyCtrl">

</canvas> 
</div>
<script>document.write("<base href='"" + document.location + "'" />");</script>

<script src="bootstrap.min.js" integrity="sha384-0mSbJDEHialfmuBBQP6A4Qrprq5OVfW37PRR3j5ELqxss1yVqOtnepnHVP9aJ7xS" crossorigin="anonymous"></script>

<script type="text/javascript" src="Chart.js"></script>
<script type="text/javascript" src="angular-chart.js"></script>
<script src="app.js"></script>
</body>
</html>

这是我的JS文件

var app = angular.module("MyApp", ["ngAnimate", "angular-chart"]);
  app.controller('MyCtrl', function($scope, $timeout) {
             $scope.name = '';    
             $scope.data = {
         singleSelect: null,
             multipleSelect: [],
             option1: 'option-1',
        };
           $scope.forceUnknownOption = function() {
            $scope.data.singleSelect = 'nonsense';
        };
            $scope.polarData = {
            labels: ["January", "February", "March", "April"],
            data: [50, 50, 50, 50],
            };
  });
您需要

在画布上添加chart-click="onClick"属性。

并将此方法添加到您的控制器

 $scope.onClick = function (points, evt) {
    console.log(points, evt);
  };
