创建项目表
CREATE TABLE IF NOT EXISTS `items` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`title` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`description` text COLLATE utf8_unicode_ci NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=16 ;然后执行步骤2：在application/config/routes.php中添加路由器并添加以下行
$route['item'] = "item";
$route['itemDelete']['post'] = "item/deleteAll";然后执行步骤3：创建项目控制器我们将使用deleteAll（）和index（）创建这个控制器，为此我们将创建一个item.php文件，然后添加代码，如下所示：
<?php
defined('BASEPATH')OR exit('No direct dcript not allowed');
class Item extends CI_Controller{
public function __construct()
{
parent::__construct();
$this->load->database();
}
public function index(){
$data['data']=$this->db->get("items")->result();
$this->load->view('item',$data);
}
public function deleteAll(){
$ids=$this->input->post('ids');
$this->db->where_in('id', explode(",", $ids));
$this->db->delete('items');
echo json_encode(['success'=>"Item Deleted Successfully."]);
}
}
?>然后步骤4：创建一个名为item.php的视图文件视图文件将在application/views/item.php中创建
<!DOCTYPE html>
<html>
<head>
<title>Delete Multiple Records with checkbox</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />

<div class="container">

</div>

<table class="table table-bordered" style="margin-top: 20px;">

<tbody>
<?php foreach($data as $item){?>
<tr>
<td><input type="checkbox" class="sub_chk" data-id="<?php echo $item->id; ?>"></td>
<td><?php echo $item->title; ?></td>
<td><?php echo $item->description; ?></td>
</tr>
<?php } ?>
</tbody>
</table>
</div>
<script type="text/javascript">
$(document).ready(function() {
$('#master').on('click', function(e) {
if ($(this).is(':checked', true)) {
$(".sub_chk").prop('checked', true);
} else {
$(".sub_chk").prop('checked', false);
}
});
$('.delete_all').on('click', function(e) {
var allVals = [];
$(".sub_chk:checked").each(function() {
allVals.push($(this).attr('data-id'));
});
if (allVals.length <= 0) {
alert("Please select row.");
} else {
var check = confirm("Are you sure you want to delete this row?");
if (check == true) {
var join_selected_values = allVals.join(",");
$.ajax({
url: $(this).data('url'),
type: 'POST',
data: 'ids=' + join_selected_values,
success: function(data) {
console.log(data);
$(".sub_chk:checked").each(function() {
$(this).parents("tr").remove();
});
alert("Item Deleted successfully.");
},
error: function(data) {
alert(data.responseText);
}
});
$.each(allVals, function(index, value) {
$('table tr').filter("[data-row-id='" + value + "']").remove();
});
}
}
});
});
</script>
</body>

您不能像CodeIgniter 3中那样定义路由。您需要从
itemDelete路由中删除['post']。但是，如果您确实希望将该路由限制为仅
POST请求，我想您可以执行如下操作：
