我用chartjs
创建了一个饼图,
但是当我点击特定切片时,不会执行点击事件。
查看:
<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));
}
//...
}
我的代码出了什么问题?
请注意:我没有使用angular-chart.js

我研究了你的问题并正在阅读 @MohammadMansoor 的回答我尝试为你实施解决方案。
(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);

使用html onclick功能并使用任何ID
访问范围 <?php
require_once 'excel_reader2.php';
$data = new Spreadsheet_Excel_Reader($url);
$page_sheet = 1;
if(count($data->sheets[$page_sheet][cells])>0) // checking sheet not empty
{
$rows = count($data->sheets[$page_sheet][cells]);
for($j=5;$j<=count($data->sheets[$page_sheet][cells]);$j++) // loop used to get each row of the sheet
{
$data->sheets[$page_sheet][cells][$j][1];
$rowid = $data->sheets[$page_sheet][cells][$j][1];
$phone = $data->sheets[$page_sheet][cells][$j][2];
$season = $data->sheets[$page_sheet][cells][$j][3];
$row = $data->sheets[$page_sheet][cells][$j][4];
$name = $data->sheets[$page_sheet][cells][$j][5];
echo "$name<br />";
}
}

如果您使用angular-chart
,请使用chart-click = "chartClick"
。
我认为chart.js
会覆盖点击事件,并且不会将其传递给角度,因此您无法触发ng-click
事件。
您可以尝试使用angular.element('#myPieChart')
在外部绑定点击事件,但我不确定。
