Answer 1

Please check with this

<td class="paid"><a href="invoice.php?id=<?php echo $invoice_result['id']; ?>" onclick="confirmChk()"><img src="images/view_3.gif"/></a></td>

    <script type="text/javascript">
    function confirmChk(){
    if(confirm("Do you realy want do delete this vehicle?")){
    return true;
    }
    else{
    return false;
    }
    }
    </script>

NB:The problem was with your function name I changed it confirm to confirmChk

Answer 2

You're trying to overload "confirm" function, which is built-in function and thus your code is not working. Change the name of your function from confirm to something else.

Answer 3

try this...

<td class="paid">
<span onclick="return confirm('Do you realy want do delete this vehicle?')">
<a href="invoice.php?id=<?php echo $invoice_result['id']; ?>"><img src="images/view_3.gif"/></a>
</span>
</td>

Answer 4

将函数名称更改为除确认以外的其他名称。

Answer 5

Use this

onClick="return confirm('Do you realy want do delete this vehicle?');"

..

<td class="paid"><a href="invoice.php?id=<?php echo $invoice_result['id']; ?>"
onClick="return confirm('Do you realy want do delete this vehicle?');">
<img src="images/view_3.gif"/></a></td>

The error happened to you cos of the reserved word confirm .
