How can I pass a PHP string into a Javascript function call?

Question

I simple want to wan to pass php string into java script function here is the code. I know there is problem in sending string to javascript function but how can i solve it????If i pass integer value then it works fine it shows problem in passing string

echo "<td><a id='".$row['Patient_Id']."' onclick=changename(".$row['Patient_Id'].",".$row['age'].",".$row['Notes'].") >".$row["Patient_Name"]."</a></td></tr>";

Here is the java script funtion

function changename(vlue,age,id)
{
 alert(id);
 var MyDiv1 = document.getElementById(vlue);
 document.getElementById('age').innerHTML=age;          
 var MyDiv2 = document.getElementById('pname');
 MyDiv2.innerHTML = MyDiv1.innerHTML;   //d     
 var MyDiv3 = document.getElementById('hidden');
 MyDiv3.value  =vlue;               
}

There shouldn't be a problem here if the echo worked correctly. — Jay Blanchard

Look at the actual HTMl output of the table data - see anything weird there? — Jay Blanchard

Your parameters are string values, so they should be enclosed in quotes:

echo "<td><a id='".$row['Patient_Id']."' onclick=changename( '".$row['Patient_Id']."' , '".$row['age']."' , '".$row['Notes']."' ) >".$row["Patient_Name"]."</a></td></tr>";
//                                                           ^----------------------^ etc

As it stands, JavaScript perceives your strings as identifiers. If you had checked your console you'd have seen corresponding errors (assuming these identifiers aren't defined).

your onclick doesn't have quotations

echo "<td><a id='".$row['Patient_Id']."' onclick='changename(".$row['Patient_Id'].",".$row['age'].",".$row['Notes'].")' >".$row["Patient_Name"]."</a></td></tr>";
                                                 ^ //here                                                             ^ // and here
