CodeIgniter锚点链接中的确认框以删除记录 - Confirm box in CodeIgniter anchor link to delete record

我使用以下代码从数据库中删除一条记录。但我面临一个问题:当我点击"取消"在确认框，然后它删除记录。如果我点击cancel，它返回false，但它如何删除记录?

我做错了什么?

Javascript代码:

function ConfirmDialog() {
  var x=confirm("Are you sure to delete record?")
  if (x) {
    return true;
  } else {
    return false;
  }
}

PHP代码:

<?php
  echo anchor('user/deleteuser/'.$row->id, 'Delete', array('class'=>'delete', 'onclick'=>"return ConfirmDialog();"));
?>

一行

<?=anchor("user/deleteuser/".$row->id,"Delete",array('onclick' => "return confirm('Do you want delete this record')"))?>

Try This:

<a href="javascript:void(0);" onclick="delete(<?php echo $row->id;?>);">Delete</a>

并在脚本中使用:

<script type="text/javascript">
    var url="<?php echo base_url();?>";
    function delete(id){
       var r=confirm("Do you want to delete this?")
        if (r==true)
          window.location = url+"user/deleteuser/"+id;
        else
          return false;
        } 
</script>

你在控制台得到任何Javascript错误吗?我怀疑可能有其他Javascript在干扰。这个简单的测试页面运行良好:

<?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>

中的视图:

<?= anchor("admin/delete_article/{$article->id}", 'Test', ['name'=>'submit', 'value'=>'Delete', 'class'=>'btn btn-danger', 'onclick'=>'return confirm()']);
?>

或

<?=
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在你的视图:

<script>
function confirm(){
  job=confirm("Are you sure to delete permanently?");
if(job!=true){
  return false;
  }
}
</script>

我在我的代码中使用了这个

<a href='<?php site_url('controler/function/$id');?>' onClick='javascript:return confirm('"Are you sure to Delete?'")'>Delete</a>

试试这个

<a href="javascript:;" onclick="return isconfirm('<?php echo site_url('user/deleteuser/'.$row->id); ?>');">Delete</a>

那么你的函数将是这样的:

function isconfirm(url_val){
    alert(url_val);
    if(confirm('Are you sure you wanna delete this ?') == false)
    {
        return false;
    }
    else
    {
        location.href=url_val;
    }

 <?= 
      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();
    ?>

这是删除代码。首先我们打开表单admin是我们的控制器名delete_noti是admin控制器内的函数。我们发送id作为隐藏表单。这里$notification是通过控制器中可用的方法传递的变量。

最后，如果您想要javascript确认:所以当用户单击时，它要求确认，然后如果用户单击ok就去删除。当行已经被删除时，您要求确认。

In View Page:-

<td><a href="<?php echo base_url().'user/deleteuser/'.$user['user_id'];?>" class="btn btn-danger" onclick="return confirm('Are you sure want to Delete this User?')">DELETE</a></td>

控制器代码:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class user extends CI_Controller {
public function deleteuser($userid)
    {
      $this->db->delete('user', array('user_id'=>$userid)); 
      $this->session->set_flashdata('success','User deleted Successfully!!!');
            redirect(base_url().'admin/user');
    }
}
?>

Then Show Success Message on View:-

<div class="row col-md-12">
<?php 
   if($this->session->flashdata('success')){
 ?>
   <div class="alert alert-success "  style="display:none;"> 
     <?php  echo $this->session->flashdata('success'); ?>
<?php    
} else if($this->session->flashdata('error')){
?>
 <div class = "alert alert-danger"  style="display:none;">
   <?php echo $this->session->flashdata('error'); ?>
 </div>
<?php } ?>
</div></div>
