ng-click不使用chart.js

Question

我創建了一個帶有chartjs的餅圖，但是當我單擊特定切片時，不會執行click事件。

視圖：

<div ng-controller="ProjectsController">
<a>Projects</a>
<br>
</br>
<canvas id="myPieChart" width="600" height="600" ng-click="chartClick()"></canvas>

控制器：

'use strict';

angular.module('Progs')

.controller('ProjectsController', ['$scope', '$rootScope', '$http', '$window', '$state',
function ($scope, $rootScope, $http, $window, $state) {
  //...
  $scope.chartClick = function (event) {
    console.log('chartClick');
    //console.log("segment: " + $scope.chart.getSegmentsAtEvent(event));
  }
  //...
}

我的代碼出了什么問題？

請注意：我沒有使用angular-chart.js

我研究了你的問題並且正在閱讀@MohammadMansoor的回答我試圖為你實現解決方案。

 (function(angular) { var app = angular.module("app", []); app.controller("ChartCtrl", ['$scope', function($scope) { $scope.hello = "Hello, World"; $scope.canvas = document.getElementById("myPieChart"); $scope.ctx = $scope.canvas.getContext("2d"); $scope.data = [{ value: 300, color: "#F7464A", highlight: "#FF5A5E", label: "Red" }, { value: 50, color: "#46BFBD", highlight: "#5AD3D1", label: "Green" }, { value: 100, color: "#FDB45C", highlight: "#FFC870", label: "Yellow" }]; $scope.myPieChart = new Chart($scope.ctx).Pie($scope.data,{}); $scope.chartClick = function (event) { console.log('chartClick'); console.log($scope.myPieChart.getSegmentsAtEvent(event)); } $scope.canvas.onclick = $scope.chartClick; }]); })(angular); 

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.js"></script> <div ng-app="app" ng-controller="ChartCtrl"> <h1>{{hello}}</h1> <a>Projects</a> <br> <canvas id="myPieChart" width="600" height="600"></canvas> </div> 

這是相同實現的插件

使用html onclick功能並使用任何ID訪問范圍

例：

<canvas id="myPieChart" width="600" height="600" onclick="angular.element("#myPieChart").scope().chartClick();"></canvas>

如果您使用angular-chart請使用chart-click = "chartClick" 。

我想chart.js會覆蓋click事件並且不會將其傳遞給angular，因此您無法觸發ng-click事件。

您可以嘗試使用angular.element('#myPieChart')在外部綁定click事件，但我不確定。
