问题描述
我将Typeahead自动完成搜索应用于"master.blade"，现在我的导航栏中有可用的搜索字段，该字段包含在网站内的所有位置.我的自动完成建议工作正常，但没有显示搜索结果.如何显示搜索结果?
I applied Typeahead autocomplete search to my "master.blade" and now I have search field available inside my navigation bar that is included everywhere inside my site. My autocomplete suggestions work fine but its not showing me the searched results. How can I display the search results?
我的路线:
Route::get('search',array('as'=>'search','uses'=>'AutoCompleteController@search'));
Route::get('autocomplete',array('as'=>'autocomplete','uses'=>'AutoCompleteController@autocomplete'));
我的AutoCompleteController:
My AutoCompleteController:
<?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)
{
$data = Product::select("title")->where("title","LIKE","%{$request->input('query')}%")->get();
return response()->json($data);
}
}
我的master.blade:
My master.blade:
<head>
<meta charset="UTF-8">
<title>@if (!empty($title) )
{{ $title }}
@else
MyHero
@endif</title>
<meta charset="UTF-8">

推荐答案
要将模型转换为JSON，应使用toJson()方法.与toArray一样，toJson方法也是递归的，因此所有属性和关系都将转换为JSON:
To convert a model to JSON, you should use the toJson() method. Like toArray, the toJson method is recursive, so all attributes and relations will be converted to JSON:
public function autocomplete(Request $request)
{
if( !empty(request('query'))){
$data = Product::select("title")
->where("title","LIKE","%{$request->input('query')}%")
->get();
$dataJson =$data->toJson();
return view('master', compact('dataJson'));
}else
return view ('master');
}
如果您确实要在视图中使用json编码的数据，请在foreach中使用json_decode():
If you really want to use json encoded data in a view, use json_decode() in foreach:
@if($dataJson)
@foreach(json_decode($dataJson, true) as $value)
{{ $value['record1']['record 2'] }}
@endforeach
@endif
