如何在javascript函数中传递2个PHP变量？

Question

How do I pass 2 PHP variables in a javascript function?

This one is working

 echo '<button onClick = "count('.$increment.')">'.$counter.' </button>';

but when i do this

  echo '<button onClick = "count('.$increment.','.$pass.')">'.$counter.' </button>';

it does not work, what is the problem?

By the way these are the variables:

    $increment=5;
    $pass="sdfgd";

Answer 1

echo '<button onClick = "count('.$increment.',\''.$pass.'\')">'.$counter.' </button>';
