I have a problem in my code, I want to put $meaning variable into innerhtml of my di,here is my code: searchinput.php:

<form action = "search.php" method = "post">
    <input name="word" id="word" type="text" maxlength="255" />

    $meaning = $fetchmeaning['meaning'];
?>

now I want to have this:

document.getElementById('meaning').innerhtml = $meaning; !!!!

how can I impelemt this?

Answer 1

Yes. Start a script tag after the definition of $meaning and put the below code in it. Like.

document.getElementById('meaning').innerHTML = "<?PHP echo $meaning; ?>" ;

Also Can't you think of directly echo ing the value of $meaning inside the div without even using javascript? like

<div id = "meaning"><?PHP echo $meaning; ?></div>

You can also use the short form <?=$meaning?>.

Answer 2

 <div id="errorMessage"></div>
 <?php
  if (isset($_GET['q'])) {
  echo '<script type="text/javascript">
  document.getElementById("errorMessage").innerHTML = "User name or Password is incorrect";
  </script>';

  }
  ?>
