无法从数据库中获取 CI 自动完成功能

Can't get CI autocomplete from DB to work

我最近动手 CI 并且还在学习。

我的控制器:

public function test() {
    $keyword=$this->input->post('search[1]');
    $data=$this->hbc_model->search_autocomplete($keyword);        
    //echo json_encode($data);

    $this->load->view('headfoot/test-header-main');
    $this->load->view('test');
    $this->load->view('headfoot/test-footer-main');
}

型号:

function search_autocomplete($search_term){
    $this->db->select('v_city_name'); 
    $this->db->like('v_city_name', $search_term);
    $response = $this->db->get('vbc_city')->result_array();
    // var_dump($response);
    return $response;
}

并查看:

<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.0/themes/base/jquery-ui.css" />
<script src="http://code.jquery.com/jquery-1.8.3.js"></script>
<script src="http://code.jquery.com/ui/1.10.0/jquery-ui.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
    $( "#main-search" ).autocomplete({
    source: 'hbc_Model/search_autocomplete'
    });
    });
</script>
</head>
<body>
<input type="text" id="main-search" name="search[1]" size="20" />
</body>

当我从模型中取消注释 vardump 甚至回显来自控制器的 json 响应时,它从数据库中在整个页面上显示城市名称,但在用作自动完成时不起作用。

如有任何帮助,我们将不胜感激。

自动完成需要 proper formatted 源数据: 我会这样进行:

 $response = $this->db->get('vbc_city')->result_array();
 $outputString="";
foreach ($response as $city)
$outputString.="'".$city['v_city_name']."',";

print "[".substr(SoutputString,0,-1)."]";
die; // or else the page html will be printed too!
