HTTP请求上的404

Question

当我尝试向Codeigniter路由发出Ajax请求时，出现404错误

项目的根文件夹是 http://localhost/control_cuotas/

这是控制器（索引有效）：

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Control_cuotas_controller extends CI_Controller {

    public function index()

    {

        $data = array();

        $tables = $this->getTables();

        $data['tables'] = $tables;

        $this->load->view('main/main_view', $data);      

    }

    public function getData($data){

        var_dump($data);

    }

    private function getTables(){

        $sql = "SELECT TABLE_NAME " 

            ."FROM INFORMATION_SCHEMA.TABLES "

            ."WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_NAME LIKE 'datos_%'";

        $query = $this->db->query($sql);

        $tables = array();

        foreach ($query->result() as $row){

            $name = substr($row->TABLE_NAME,0,-2);

            if(!in_array($name,$tables)){

                array_push($tables, $name);

            }

        }

        return $tables;

    }

这是javascript：

$(document).ready(function(){

    $('#tables').change(function(){

        var selected = $(this).val();

        $.ajax({

            url:'getData/'+selected

        });

    });

});

}

这是路线

$route['getData/(:any)']['GET'] = 'control_cuotas_controller/getData/$1';

该请求是在以下网址上完成的

http://localhost/control_cuotas/getData/selected_value

请检查.htaccess文件并尝试此代码；RewriteEngine onRewriteCond $1 !^(index\.php|public|\.txt)RewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule ^(.*)$ index.php?$1或者$(document).ready(function(){&nbsp; &nbsp; $('#tables').change(function(){&nbsp; &nbsp; &nbsp; &nbsp; var selected = $(this).val();&nbsp; &nbsp; &nbsp; &nbsp; $.ajax({&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; url:'http://localhost/control_cuotas/getData/'+selected&nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp; });});}
