只有在开发人员工具中设置了调试点时,Javascript/ajax脚本才能工作

我正面临以下问题,似乎无法解决。 我们正在开发一个与CodeIgniter3网站。 用于将文件上载到我使用的站点Dropzone.js文件

我想实现以下目标: addRemoveLinks:真

同时,我将文件参数(id、名称、大小等)保存到数据库中。 在这个站点上,视频缩略图是基于数据库行加载的,所以当取消上载时,我想从db中删除相关的行。

问题是,我的代码只有在Chrome开发工具中设置调试点时才能工作,但是代码的处理时间仍然很长。

这是我的密码页脚

                url: './delete2/' + name,
                type: "GET",
                success: function(html) {
                    location.reload();
                }
            });

        });

        this.on("queuecomplete", function() {
            location.reload();
        });
    }
}

</script>

出于某种原因,如果没有$ajax的调试点,代码不会从db中删除。 有什么建议吗?

@亚历克斯,这是上传和删除功能

public function delete_video2($video_name){

    $this->db->where('video_name', $video_name);
    $this->db->delete('videos');        

}

// Add Video
public function add_video()
{

    $this->load->helper('url');

    //allowed file types
    $arr_file_types = ['video/mp4', 'video/avi', 'video/mov', 'video/3gp', 'video/mpeg'];

    // Target Path
    $target_dir = "./assets/upload/";
    // Assigining Random Name
    $File_Name          = $_FILES["file"]["name"];          // Get file name
    $File_Size          = $_FILES["file"]["size"];          // Get file name
    $File_Ext           = substr($File_Name, strrpos($File_Name, '.')); // Get file extention
    $Random_Number      = rand(0, 9999999999);                          // Random number to be added to name.
    $NewFileName        = $Random_Number.$File_Ext;                     // New file name

    // Uploading name to dataase

    move_uploaded_file($_FILES['file']['tmp_name'], $target_dir.$NewFileName);
    // echo "true";
    // die();

    $user = $this->ion_auth->user()->row();
    $id = $user->id;

    $data = array(
        'reference_id' => $File_Ext,
        'user_id' => $id,
        'video_name' => $File_Name,
        'video_url' => $NewFileName,
        'video_size' => $File_Size,
    );

    return $this->db->insert('videos', $data);

}

释放视图的部分
