我的主 Blade View 不会显示自动完成表单的搜索结果。它只是刷新页面并保持不变。我在我的主 Blade 中使用了 TypeAhead 插件。我的搜索表单在我的主 Blade 中。有什么想法可能是什么问题吗？

我的路线:

Route::get('search',array('as'=>'search','uses'=>'AutoCompleteController@search'));
Route::get('autocomplete',array('as'=>'autocomplete','uses'=>'AutoCompleteController@autocomplete'));

我的 Controller :

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Product;
class AutoCompleteController extends MainController {

      public function search()
    {
        return view('master');
    }

     public function autocomplete(Request $request)
     {

if( !empty(request('query'))){

        $data = Product::select("title")
        ->where("title","LIKE","%{$request->input('query')}%") 


->get(); 
         dd('justrandom');
     $dataJson =$data->toJson();
        return view('master', compact('dataJson'));
}else{ 

  return view ('master', ['dataJson' => false]);

}

    }
}

我的主刀:

<head>
    <meta charset="UTF-8">
    <title>@if (!empty($title) )
        {{ $title }}  
        @else
        MySite
        @endif</title>

最佳答案

您似乎有语法错误，此处:

@if(!empty($dataJson))
@foreach(json_decode($dataJson, true) as $value)
   {{ $value['record1']['record 2'] }}   
@endforeach
$endif

那个$endif肯定应该是@endif..？
