echo '<td onclick="getdesc(\'$descriptn\')">';

But in this i am not geting the value of variable $descriptn is directly printing .

Answer 1

Change to

echo '<td   style="margin-top: 3px; padding: 3px 2px; background: none repeat scroll 0px 0px #E9E9E9;" onclick="getdesc(\''.$descriptn.'\')" >';

Answer 2

use double quote for this, that was the mistake.

echo "<td   style='margin-top: 3px; padding: 3px 2px; background: none repeat scroll 0px 0px #E9E9E9;' onclick='getdesc(\'$descriptn\')' >";
