404找不到错误Ajax Laravel 5.1

Question

I'm trying to get the subcategories on the base of a category in laravel 5.1 but first it was giving me an error of '500 internal server error' but I include

RewriteBase /

in my .htaccess file and nos it is giving me en error of 'not found 404 error'. I'm using a virtual host and Form facade which automatically includes 'csrf token', so I think it's not the problem of 'csrf' token problem. Can any one help in this regard?????

This is my route file:

// Admins Tasks

Route::group(['middleware'=>'admin'], function() {

//Route::resource('/showcategoreis/{$id}', 'AdminHelperContooler@filterSubcat');
Route::get('/ajax-subcat/{id}', function(){
    return "mkj";
   $cat_id = Input::get('cat_id');
   $subcategories = Subcategory::where('category_id', '=', $cat_id)->get();

   return Response::json($subcategories);
});

Route::resource('/admin', 'Admin\AdminController');
Route::resource('/user', 'UserController');
Route::resource('/province', 'ProvinceController');
Route::resource('/city', 'CityController');

Route::resource('/category', 'CategoryController');


Route::resource('/subcategory', 'SubcategoryController');
Route::resource('/brand', 'BrandController');
Route::resource('/model', 'BModelController');
});

Answer 1

The route you've defined is '/ajax-subcat/{id}' but the you're trying to call '/ajax-subcat?cat_id='+cat_id in your AJAX. Change your route to '/ajax-subcat' and that should at least fix your 404 error.

Alternately, you could change your AJAX to call '/ajax-subcat/'+cat_id
