This

echo '<a onclick="add('.$row["x"].','.$row["y"].')" href="javascript:void(0)">';

will gives you

<a onclick="add(a,b)" href="javascript:void(0)">

You need to add single quotes if you are passing strings to your function, like this

echo '<a onclick="add(\''.$row["x"].'\',\''.$row["y"].'\')" href="javascript:void(0)">';

Then in your document you will get

<a onclick="add('a','b')" href="javascript:void(0)">

Try this

'<a href="javascript:add('.$row["x"].','.$row["y"].')">'

OR

'<a onclick="add('.$row["x"].','.$row["y"].')" href="#">'

Or

'<a onclick="add('.$row["x"].','.$row["y"].') return false" href="#">'

Try to something like this.

Php File

<?php
     echo '<a onclick="add('.$row["x"].','.$row["y"].')" >Onclick Function</a>';
 ?>

.html file

<a onclick="add(<?= $row["x"] ?>,<?= $row["y"] ?>)" href="javascript:void(0)">Onclick Function</a>
