Jquery Autocomplete 显示一个空列表

Question

编辑 2：更好的是，多个值有效

实际上，只需提供一个填满框的“值”字段。不需要“id/label”字段，但需要 value 字段。这是有效的：

foreach ($queries as $query)
        {
          $results[] = [
            'zip' => $query->zip,
            'value' => $query->commune,
            'libelle' => $query->libelle,
            'lieudit' => $query->lieudit
          ];
        }
return Response::json($results);

编辑：这是解决方案，感谢 Adyson 的回答

脚本应该是json格式并返回

具有label 和value 属性的对象数组：

[ { label: "Choice1", value: "value1" }, ... ]

(jQuery API documentation)

所以，像这样修改 PHP 脚本就可以了：

foreach ($queries as $query)
        {
          $results[] = [
            'id' => $query->zip,
            'value' => $query->commune,
          ];
        }
return Response::json($results);

原始问题

使用 Jquery Autocomplete，查询脚本。

列表显示与结果一样多的行（当我将脚本设置为返回 X 个结果时，列表中也有 X 行）：

但它不会用数据填充行。那里可能出了什么问题？

返回的数据是一些json：

Request URL:http://localhost:8000/search/autocomplete?term=750
Request Method:GET
Status Code:200 OK
Remote Address:127.0.0.1:8000
Response Headers
view source
Cache-Control:no-cache
Connection:close
Content-Type:application/json
Date:Tue, 15 Nov 2016 14:53:07 GMT
Host:localhost:8000

这是数据：

[{"zip":"75004","commune":"PARIS 04","libelle":"PARIS","lieudit":""},
{"zip":"75005","commune":"PARIS 05","libelle":"PARIS","lieudit":""},
{"zip":"75003","commune":"PARIS 03","libelle":"PARIS","lieudit":""},
{"zip":"75006","commune":"PARIS 06","libelle":"PARIS","lieudit":""},
{"zip":"75008","commune":"PARIS 08","libelle":"PARIS","lieudit":""},
{"zip":"75012","commune":"PARIS 12","libelle":"PARIS","lieudit":""},
{"zip":"75015","commune":"PARIS 15","libelle":"PARIS","lieudit":""},
{"zip":"75016","commune":"PARIS 16","libelle":"PARIS","lieudit":""},
{"zip":"75017","commune":"PARIS 17","libelle":"PARIS","lieudit":""},
{"zip":"75010","commune":"PARIS 10","libelle":"PARIS","lieudit":""},
{"zip":"75018","commune":"PARIS 18","libelle":"PARIS","lieudit":""},
{"zip":"75001","commune":"PARIS 01","libelle":"PARIS","lieudit":""},
{"zip":"75009","commune":"PARIS 09","libelle":"PARIS","lieudit":""},
{"zip":"75014","commune":"PARIS 14","libelle":"PARIS","lieudit":""},
{"zip":"75002","commune":"PARIS 02","libelle":"PARIS","lieudit":""},
{"zip":"75007","commune":"PARIS 07","libelle":"PARIS","lieudit":""},
{"zip":"75011","commune":"PARIS 11","libelle":"PARIS","lieudit":""},
{"zip":"75013","commune":"PARIS 13","libelle":"PARIS","lieudit":""},
{"zip":"75019","commune":"PARIS 19","libelle":"PARIS","lieudit":""},
{"zip":"75020","commune":"PARIS 20","libelle":"PARIS","lieudit":""}]

这是我的 JS：

$(function(){
     $( "#fromzip" ).autocomplete({
        source: "/search/autocomplete",
        dataType: 'json',
        minLength: 3,
     });
  });

HTML：

<input 
      id="fromzip"
      name="fromzip"
      type="text"
      class="form-control"
      placeholder="69003"
      pattern=".{5}"
      title="5 numbers zip"
      maxlength="5"
      required >

还有 PHP（Laravel 输入、数据库和响应门面）：

public function autocomplete(){
        $term = Input::get('term');
        $results = array();

        $queries = DB::table('zips')
          ->where('zip', 'LIKE', $term.'%')
          ->orWhere('libelle', 'LIKE', $term.'%')
          ->take(30)->get();

        foreach ($queries as $query)
        {
            $results[] = [ 'zip' => $query->zip,
            'commune' => $query->commune,
            'libelle' => $query->libelle,
            'lieudit' => $query->lieudit];
        }

        return Response::json($results);

      }

看看http://api.jqueryui.com/autocomplete/#option-source。它指出数据必须采用格式

[ { label: "Choice1", value: "value1" }, ... ] 

您的示例数据项没有这些属性（标签或值）。

您可以修改服务器端脚本以输出正确的格式，或者如果您不能/不会这样做，您可以使用插件中的 source-as-a-function 选项来编写一个函数转换数据。
