I would like to insert a javascript alert in my action button

Navigation
0

first the action call to delete 

<?php
$aux = 0;
while($resultado = mysql_fetch_object($query))
{
$url_alterar = "form_alterar.php?cod=".$resultado->id;
$url_excluir = "excluir_cad.php?cod=".$resultado->id;
if ($aux % 2 == 0)

Now the action button 

<?="<td><a href=".$url_excluir."><img src='delete.jpg' height='35' width='35'></a></td>";?>

I got this code here on the internet 

<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">
decisao = confirm("Clique em um botão!");
if (decisao){
alert ("Você Apagou o Registro,\n"+decisao);
} else {
alert ("Voce CANCELOU,\n"+decisao);
}
</SCRIPT>

I have tried it anyway without success, I believe that the way it sends the variable to the system would not allow it to use this jscript resource. I already tried to use direct in the action of the button but it did not give result, neither in the page that is called or in the code explained above. I am asking for help because on September 27 I present my work in college and would like to 'spruce' since everything works perfectly. Thank you for helping me! hugs

Inline example: 

<a href="delete.php" onclick="return confirm('Prosseguir com a ação?');">excluir</a>

To be clearer, for you: 

<?="<td><a href=".$url_excluir." onclick="return confirm('Prosseguir com a ação?');><img src='delete.jpg' height='35' width='35'></a></td>";?>

Then the <script>...</script> excerpt can be deleted.


I'll just suggest you change a little. 

<td><a href="<?php echo $url_excluir;?>" onclick="return confirm('Prosseguir com a ação?');><img src='delete.jpg' height='35' width='35'></a></td>
