Laravel5中的jQuery Autocomplete不起作用


jQuery Autocomplete in Laravel5 not working

这是基本代码。我似乎无法让它在Laravel 5:中工作

routes.php

Route::get('h2h', 'atp_players'H2hController@getIndex');
Route::get('h2h_getdata', 'atp_players'H2hController@getData');

H2hController.php

namespace Atpstats'Http'Controllers'atp_players;
use Atpstats'Http'Controllers'Controller;
use Response;
use Request;

class H2hController extends Controller{
public function getIndex() {
    return view('atp_players.h2h');
}
public function getData() {
    $term =  Request::input('auto', 'r');
    $results = 'DB::table('atp_players')->select('firstname')->get();
    $data = array();
    foreach($results as $result) {
         if(strpos($result,$term) !== false) {
            $data[] = ['value' => $result->firstname];
        }
    }
    return Response::json($data);
}
}

视图:h2h.blade.php

它不起作用。当您向输入文本大小写一些内容时,它就是无所事事事件。但是,如果我在Controller中注释一些行,则会显示DB的数据(名字),但自动完成不起作用。

这就是修改后的控制器功能:

public function getData() {
    //$term =  Request::input('auto', 'r');
    $results = 'DB::table('atp_players')->select('firstname')->get();
    $data = array();
    foreach($results as $result) {
         //if(strpos($result,$term) !== false) {
            $data[] = ['value' => $result->firstname];
        //}
    }
    return Response::json($data);
}

我认为问题可能出在服务器端代码上。尝试将表单项名称从"auto"更改为"term",如下所示:

...
public function getData() {
$term =  Request::input('term', 'r');
...

嘿,我觉得另一个人走对了路。问题在于您的源json。您正在打印格式正确的JSON,它只需要位于正确的密钥对中即可自动完成。根据source属性的Jquery UI自动完成文档,如果要使用数组,则必须使用label:value: 对其进行正确格式化

所以只需像一样格式化数据

public function getData() {
//$term =  Request::input('auto', 'r');
$results = [['firstname' => 'Edwardo', 'ID' => '12'], ['firstname' => 'Edwarda', 'ID' => '13']];
//$results = 'DB::table('atp_players')->select('firstname')->get();
$data = array();
foreach($results as $result) {
     if(strpos($result,$term) !== false) {
        $temp = array();
        // This is what will be displayed by autocomplete
        $temp['label'] = $result->firstname;
        // This will be the value you get back through form (eg: User_ID)
        $temp['value'] = $result->ID;
        array_push($data, $temp);
    }
}
return Response::json($data);

}

这是一个预填充json数组的工作小提琴https://jsfiddle.net/7u73czt8/

但如果你只想搜索它,你也可以只给它一个值,它会提交第一个名字作为输入标签值。
