Question

我有一个这样的控制器：Author

unitselector.php

视图：unitselector

<?php

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

class Unitselector extends CI_Controller {

function __construct() {
    parent::__construct();
    //$this->load->model(array('Transaksi_model', 'Pelanggan_model'));
    //chek_session();
}

function index() {
    if (!$this->ion_auth->logged_in()) {
        // redirect them to the login page
        redirect('auth/login', 'refresh');
    } else{
        $this->db->order_by("unit_order");
        $data['record']=  $this->db->get('tb_unit_list')->result();
        $unitid = $this->input->get('hiddenInput');
        $data['record1']=  $this->db->query("SELECT * FROM tb_unit_location where id_unit='$unitid' ")->result();
        $data['record2']=  $this->db->query("SELECT * FROM tb_period WHERE Status = 0")->result();
        $this->load->view('unitselector/unitselector',$data);
    }
}

}

问题是：

当用户选择dropdown1时，它会将值返回<div class="form-group"> <label for="">Unit Name</label> <select id='dropdown1' name='dropdown1' class="form-control" onclick="changeHiddenInput(this)"> <option value="">Pilih...</option> <?php if (!empty($record)) { foreach ($record as $r) { echo "<option value=".$r->id_unit.">".$r->unit_name."</option>"; } } ?> </select> <input name="hiddenInput" id="hiddenInput" value="" /> </div> <div class="form-group"> <label for="">Lokasi/Cabang</label> <select id='dropdown2' name='dropdown2' class="form-control" onclick="changeHiddenInput1(this)"> <option value="">Pilih...</option> <?php if (!empty($record1)) { foreach ($record1 as $r1) { echo "<option value=".$r1->id_unit_loc.">".$r1->unit_loc_name."</option>"; } } ?> </select> <input name="hiddenInput1" id="hiddenInput1" value="" /> </div> <div class="form-group"> <label for="">Periode</label> <select id='dropdown3' name='dropdown3' class="form-control"> <option value="">Pilih...</option> <?php if (!empty($record2)) { foreach ($record2 as $r2) { echo "<option value=".$r2->id_period.">".$r2->id_period."</option>"; } } ?> </select> </div> <div class="row"> <div class="col-xs-4" style="float: right;"> <button type="submit" class="btn btn-primary btn-block btn-flat"><?php echo lang('login_proceed');?></button> </div> </div> <?php echo form_close();?> 。我需要hiddeninput成为

的搜索条件

hiddeninput1

我已经将$data['record1']= $this->db->query("SELECT * FROM tb_unit_location where id_unit='$unitid' ")->result();定义为值。但它没有效果。请帮忙。

你可以这样做：

$('#dropdown1').change(function(){
    window.location.href = 'unitselector/index?hiddenInput1=' + $(this).val();
});

或者使用ajax加载。
