Question

我试图使用jquery.autocomplete.js进行自动完成。不幸的是，当我尝试键入要输入的内容时，调试器出现了SyntaxError：JSON.parse：JSON数据第1行第1列的意外字符。我仍然是codeigniter的新手，所以有人可以帮我解决这个问题吗？

Java脚本

<script type='text/javascript'>
    $(function(){
      $("#asisten").autocomplete({
        source: "<?php echo base_url() ?>index.php/asisten/search"
      });
    });
</script>

控制器

public function search()
{   
    $keyword = $this->uri->segment(3);

    $data = $this->db->from('mahasiswa')->like('nim',$keyword)->get();  

    foreach($data->result() as $row)
    {
        $arr['query'] = $keyword;
        $arr['suggestions'][] = array(
            'nama'  =>$row->nama
        );
    }

    echo json_encode($arr);
}

输入HTML

<input id="asisten" type="search">

JSON数据

{"query":"7","suggestions":[{"nama":"Pedro Nadirio"},{"nama":"Antony Hartono"},{"nama":"Juan"},{"nama":"Yonathan Aditya"},{"nama":"Edwin Widhiyanto"},{"nama":"Windy Hendra S"}]}

在您的控制器中：尝试这样..

public function search()
    {   
        $keyword = $this->uri->segment(3);

        $data = $this->db->from('mahasiswa')->like('nim',$keyword)->get();  

        foreach($data->result_array() as $row)
        {
         $arr[] = $row['nama'];//array of namas
        }
        echo json_encode($arr);
    }
