Question

Im new to Javascript and was wondering how i would write a function (using jQuery) that takes a paramater, and based on that returns different code. I will write the function in PHP so you understand what im trying to do.

<?php
  function direction( $l_r )
  {
    if ($l_r == 'left') $dir = '-';
    elseif ($l_r == 'right') $dir = '+';

    echo 'the direction is '. $dir;
    echo '(than theres some more going on here)';
  }
?>

Answer 1

  function direction( l_r )
  {
    var dir;
    if (l_r == 'left') dir = '-';
    else if (l_r == 'right') dir = '+';

    return 'the direction is ' + dir;
  }
