JavaScript确认删除无效

Question

I am using cakephp version 2.x.

I am getting one trouble while deleting any record. I want to show confirmation message before delete my record. The JavaScript onclick function not working. Please check below code.

Code:

<?php
  echo $this->Html->image('delete.png', array(
  'title' => 'Delete',
  'alt' =>'Delete' ,
  'url' => array(
    'controller' => 'products',
    'action' => 'deletequery/'.$query['Query']['id']),array('confirm' => 'Are you sure you want to delete?')
    )
  );
?>

OutPut:

<a href="/products/deletequery/15">
   <img delete?="Are you sure you want to delete?" to="" want="" sure="" you="" are="" alt="Delete" title="Delete" src="/img/delete.png">
</a>

Answer 1

Change your code like this because your code is incorrect.

<?php 
 echo $this->Html->link($this->Html->image('delete.png'),
    array(
        'controller'=>'products',
        'action'=>'deletequery',$query['Query']['id']
    ),
    array('confirm'=>'Are you sure you want to delete?','escape'=>false)
 );
?>

Output

<a 
  onclick="if (confirm('Are you sure you want to delete?')) 
  { return true; } return false;" 
  href="/ABC/products/deletequery">
  <img alt="" src="/ABC/img/delete.png">
</a>

You should try this in your view file there are basically two methods to delete a file. first is you can simply make cakephp $this->Html->link or seceond method you can make a $this->Form->postLink both are different. the difference between both are postLink creates a "Form tag" but link tag not create "Form" tag

1. $this->Html->link

<?php 
echo $this->Html->link($this->Html->image('delete.png').'', array('controller' => 'products', 'action' => 'deletequery',$query['Query']['id']),array('confirm'=>'Are you sure to delete ?','escape'=>false));
?> 

2. $this->Form->postLink

<?php 
 echo $this->Form->postLink($this->Html->image('delete.png').'', array('controller' => 'products', 'action' => 'deletequery',$query['Query']['id']),array('confirm'=>'Are you sure to delete ?','escape'=>false));
 ?>
