我创建了一个 Web 应用程序，它接受用户输入、查询 API、使用 PHP 处理数据，然后使用 jQuery 和 D3 将其呈现为一系列图表。我最初以程序方式设置它，但此后一直使用 Laravel 框架来实现它。我遇到的问题是 JavaScript 在最终页面中无法正常工作；我认为这与 Blade 模板系统的工作方式有关。
我知道它在加载初始图表时正在正确访问 JavaScript 文件。然而，还有一些额外的功能可以根据不同的时间跨度重新加载图表以及滚动图表中的数据。加载页面后，所有 jQuery 内容都不起作用。
无论如何，这是代码：
ROUTING: routes.php（应用程序\HTTP）
<?php
// perform GET request on root and call method 'index' on the PagesController class
// (app/Http/Controllers/PagesController.php)
Route::get('/', 'PagesController@index');
// perform POST on 'data' and call method 'process' on the PagesController class
Route::post('data', 'PagesController@process');
?>

我超出了字符限制，因此不得不删除一些代码，但我认为我已经留下了识别问题的重要内容。
基本上它可以很好地加载带有图表的页面，但是如果您尝试使用#timeSelect下拉或滚动数据#next1， 什么都没发生。
如果您需要更多信息，请告诉我 - 谢谢。
** 附加信息 **
I used https://github.com/laracasts/PHP-Vars-To-Js-Transformer https://github.com/laracasts/PHP-Vars-To-Js-Transformer为了将我的数据获取到视图来加载图表。当您使用它时，它会发布一个文件到config called javascript.js。我已经更改了它以适应我的应用程序，但这可能是我出错的地方。这是我修改后的文件：
javascript.php（配置）
return [
'bind_js_vars_to_this_view' => 'pages.data',
'js_namespace' => 'Graphs'
];
