我的Angular 2项目是使用angular-cli版本1.0.0-beta.30创建的。我正在使用ngx-charts版本4.1.2库。条形图组件工作正常,但是当我添加折线图时,运行应用程序时会引发TypeError异常。在Chrome版本38中运行时,错误是[line-chart.component.ts] [1]源文件的第240行中的“包含”功能。在Firefox中正确显示折线图
if (!values.includes(d.name)) {
values.push(d.name);
}
如何使数组包含我的应用程序已知的函数?
在我的tsconfig.json文件中,我有

我的polyfills.ts文件包含
import 'core-js/es6/array';
我查看了ngx-charts演示和其他示例,但我无法弄清楚为什么我收到错误。

我发现了问题。 polyfills.ts文件包含
// Authentication Routes...
Route::get('login', 'Auth\LoginController@showLoginForm')->name('login');
Route::post('login', 'Auth\LoginController@login');
Route::post('logout', 'Auth\LoginController@logout')->name('logout');
// Registration Routes...
Route::get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
Route::post('register', 'Auth\RegisterController@register');
// Password Reset Routes...
Route::get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm')->name('password.request');
Route::post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail')->name('password.email');
Route::get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm')->name('password.reset');
Route::post('password/reset', 'Auth\ResetPasswordController@reset');
我需要添加
import 'core-js/es6/array';
到文件。
我认为这是因为公司电脑上安装了Chrome版本。它是版本38.此版本的developer.mozilla.org页面包含支持Chrome的状态为47的状态。
