1.通過url輔助函式（路由）生成：
location.href = "{{url('user/index2')}}";

或者：location.href = "{{url::to('user/index2')}}";

2.通過別名（路由）生成，前提是在註冊路由的時候要指定別名，例如：Route::get('user/index2',['as' => 'user/index2', 'uses' => '[email protected]']);
location.href = "{{route('user/index2')}}";

或者：location.href = "{{URL::route('user/index2')}}";

3.通過控制器、方法名生成（路由不要指定別名，否則會報錯！）：
location.href =  "{{action('[email protected]dex2',['id'=>1,'author'=>'admin'])}}";
或者：location.href =  "{{URL::action('[email protected]',['id'=>1,'author'=>'admin'])}}";
當然2，3中攜帶的引數都可以在控制器中使用 Request $request 接受
