Question

控制器：test.php的

<?php
    defined('BASEPATH') OR exit('No direct script access allowed');
    class Test extends CI_Controller 
    {
        function __construct() 
        {
            parent :: __construct();
            $this->load->helper(array('form', 'url'));
            $this->load->model('Fetch_data');
        }
        public function get_stream()
        {
            $fields = $this->input->post('fields');
            $data['fields'] = $this->Fetch_data->stream_exam($fields);
            $this->load->view('header',$data);
        }
    }

查看：header.php

<script>
    $(document).ready(function(){
        $(".stream").click(function(){
            streamid = this.id;
            alert(streamid);
            fields = $("#fields").val(streamid);
            $.ajax({
                type:"POST",
                data:{"fields":fields},
                url:"<?php echo base_url('index.php/'); ?>test/get_stream",
                success:function(data){
                    alert(data);
                }
            }); 
        });
    });
</script>

我是codeigniter的新手。在我的视图中，我有一个模态，当点击其他链接时，一个模态将打开后我有一个类（流）并且当我点击流选项卡时它的ID也将值传递给输入字段名称（字段） jquery / ajax我创建了一个控制器名称Test.php，其中我将输入字段的值发布到通过控制器查询。但没有结果表明我不知道问题出在哪里。那么，我该如何解决呢？请帮忙。

谢谢

您可以尝试如下，或者您可以将json返回到ajax成功，然后使用json数据设置值

public function test()
{
    $fields = $this->input->post('fields');
    $data['fields'] = $this->Fetch_data->stream_exam($fields);
    if(!empty($data['fields']))
    {
        foreach ($data['fields'] as $fetch) 
        {
        ?>
            <div class="tab-content">
                <div role="tabpanel" class="tab-pane active" id="<?php echo $fetch['field']; ?>">
                    <div class="col-md-3">
                        <p id="p">Top Exams of <?php echo $fetch['field']; ?></p>
                        <div id="exams"></div>
                    </div>
                </div>
            </div>
        <?php        
        }
    }
}

<script>
    $(document).ready(function(){
        $(".stream").click(function(){
            streamid = this.id;
            alert(streamid);
            fields = $("#fields").val(streamid);
            $.ajax({
                type:"POST",
                data:{"fields":fields},
                url:"<?php echo base_url('index.php/'); ?>test/test",
                success:function(data){
                    $('#refresh').html(data);
                }
            }); 
        });
    });
</script>

在视图中

<div id='refresh'>

</div>
