How to pass the varchar parameter when the onclick function of javascript is pressed?

Question

May I know how to pass a varchar parameter to an onClick function, the varchar parameter is the uuid that stored in my database table and i use mysqli_fetch_array to retrieve them. A list of items will display in my html and each item is assigned with the button, when the button is pressed , it will display the uuid of the particular item in the alert window. I am able to that when the id is numeric or integer, but when I change it into the uuid or md5 id or the string, the value is failed to pass, and the button is stuck. Here is some part of my code.

<button type="button" class="btn btn-outline btn-danger" onClick="deletefun(<?php echo $row["id"]; ?>)" title="Delete">delete</button>

When the deletefun button is pressed, the alert window will pop out to display the uuid of the particular item in the list.

<script>function deletefun(data){ alert(data); </script>

Thank you for helping.

Your html/javascript code is inside a .php file? If not, your php code is not interpreted. — devneri, Oct 27 '16 at 09:15

Just add quotes around <?php echo $row["id"]; ?> in your button :

<button type="button" class="btn btn-outline btn-danger"
onClick="deletefun('<?php echo $row["id"]; ?>')"
title="Delete">delete</button>

Without these quotes, the function treats <?php echo $row["id"]; ?> as if it was the name of a variable instead of a string.
