Try This:
尝试这个：
<a href="javascript:void(0);" onclick="delete(<?php echo $row->id;?>);">Delete</a>
and use this in your script:

<script type="text/javascript">
var url="<?php echo base_url();?>";

Are you getting any Javascript errors in the console? I suspect that some other Javascript may be interfering. This simple test page works fine:
您是否在控制台中收到任何 Javascript 错误？我怀疑其他一些 Javascript 可能会干扰。这个简单的测试页面工作正常：
<?php echo anchor('user/deleteuser/'.$row->id, 'Delete', array('class'=>'delete', 'onclick'=>"return confirmDialog();")); ?>
<script>
function confirmDialog() {
return confirm("Are you sure you want to delete this record?")
}
</script>

In your View:
在您的视图中：
<?= anchor("admin/delete_article/{$article->id}", 'Test', ['name'=>'submit', 'value'=>'Delete', 'class'=>'btn btn-danger', 'onclick'=>'return confirm()']);
?>
OR
或者
<?=
form_open('admin/delete_article'),
form_hidden('article_id', $article->id),
form_submit(['name'=>'submit', 'value'=>'Delete', 'class'=>'btn btn-danger', 'onclick'=>'return confirm()']),
form_close();
?>
JavaScript in your View:
视图中的 JavaScript：
<script>
function confirm(){
job=confirm("Are you sure to delete permanently?");
if(job!=true){
return false;
}
}
</script>

<?=
form_open('admin/delete_noti'),
form_hidden('noti_id',$notification->id),
form_submit('submit','Delete',array('onclick' => "return confirm('Do you want delete this record')",'class'=>'btn btn-danger float-center')),
form_close();
?>
This is the deletion code. first of all we open form admin is our controller name and delete_noti is the function inside admin controller. We are sending id as hidden form. Here $notification is the variable which is passed through method which is available in controller.
这是删除代码。首先我们打开表单 admin 是我们的控制器名称，delete_noti 是 admin 控制器中的函数。我们将 id 作为隐藏形式发送。这里 $notification 是通过控制器中可用的方法传递的变量。

Try this
尝试这个
<a href="javascript:;" onclick="return isconfirm('<?php echo site_url('user/deleteuser/'.$row->id); ?>');">Delete</a>
Then your function will be like:
那么你的功能将是这样的：
function isconfirm(url_val){
alert(url_val);
if(confirm('Are you sure you wanna delete this ?') == false)
{
return false;
}
else
{
location.href=url_val;
}
