Question

我在当前项目中使用typeahead以及简单的查询搜索。简单的查询搜索工作得很好，但是，预先输入是部分工作，即SearchController @ autocomplete正在使用JSON进行响应，而在app.blade.php中，我有一个typeahead jquery脚本，脚本不会将json渲染/转换为HTML元素。

即使控制台也没有出错。我无法理解问题的幕后故事。我通过源代码提供所有内容。

app.blade.php

<script src="/js/jquery.min.js"></script>
    <script src="/js/bootstrap.min.js"></script>
    <script src="/js/typeahead.js"></script>
    <script type="text/javascript">

            var path = "{{ route('autocomplete') }}";
            $('input.typeahead').typeahead({
                source:  function (query, process) {
                    return $.get(path, { query: query }, function (data) {
                        return process(data);
                    });
                }
            });

    </script>
    @yield('scripts')

</body>
</html>

navbar.blade.php

<form class="navbar-form navbar-left" role="search" action="/search" autocomplete="off">
                <div class="form-group">
                    <input type="text" class="typeahead form-control" id="query" placeholder="Search Staff By Name, Designation, Department" name="query" value="{{Request::input('query')}}">

                </div>
                <button type="submit" class="btn btn-default">Submit</button>
            </form>

路由/ web.php

/ ** *搜索控制器启动 * /

Route::get('/search', 'SearchController@getResults');
Route::get('/autocomplete',[
    'uses'=>'SearchController@autocomplete',
    'as'=>'autocomplete'
]);

/**
 * Search Controller Ends
 */

SearchController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Auth;
use App\User;
use DB;

class SearchController extends Controller
{
    public function getResults(Request $request)
    {   $query = $request->input('query');
        if(!$query){
         return redirect('/home');
        }

        $users = User::where(DB::raw("CONCAT(first_name,'',last_name)"), '
                        LIKE', "%{$query}%")
                        ->orwhere('name', 'LIKE', "%{$query}%")
                        ->orwhere('department', 'LIKE', "%{$query}%")
                        ->orwhere('designation', 'LIKE', "%{$query}%")
                        ->orwhere('email', 'LIKE', "%{$query}%")
                        ->orwhere('phone', 'LIKE', "%{$query}%")
                        ->get();

        return view('search')->with('users', $users);
    }

    public function autocomplete(Request $request){
        $data = User::where("name","LIKE","%{$request->input('query')}%")->get();
        return response()->json($data);
    }

    }

一些屏幕截图

http://localhost:8000/autocomplete没问题

Typeahead部分与Laravel 5.3一起使用
