Bonjour,
j'aimerai utiliser ce code . pour ce faire je veux que la partie ou s'affiche le résultat soit un champ de type input.
ici le résultat est 555555...
j'ai l'impression que c'est dans cette partie. 
<div class="calculator">
        <div class="output">
          <div id="calculation">
            <!-- Display for calculation -->
          </div>
          <div id="input">
            <!-- Display for Input & Result -->
          </div>
        </div>


donc je veux avoir quelque chose du genre:
<div class="calculator">
<div class="output">
<div id="calculation">
<!-- Display for calculation -->
</div>
<div id="input">
<!-- Display for Input & Result -->
<input type="text" name="resultat" class="form-control" value="5555555" >
</div>
</div>
</code>

voici le code :

var divInp = document.getElementById('input');
var x = document.createElement("INPUT");
x.setAttribute("type", "text");
x.setAttribute("name", "password");
x.value = `${disResult}`;
divInp.appendChild(x);

voici le code php : 
<?php

                      echo '<script>alert(\' '.$msg.' \');</script>';

je comprends pas cette phrase :
Et ensuite...il faut placer ton input dans ta page...

C'est bien pour ça que je t'ai donné le code juste en dessous de ce message......



toujours pas de recuperation de la saisie lorsqu'on post

Là.. c'est autre chose. Rien à voir avec ta question initiale qui était : 
la partie ou s'affiche le résultat soit un champ de type input


Donc.. déjà... est ce que le champ de type INPUT se créé bien sur ta page suite à la modification que nous avons fait ?
Si tu regardes le code source généré par ton navigateur sur cet élément.. quel est-il ?


EDIT : Après avoir testé ton code directement... je pense avoir compris ce que tu souhaitais réellement faire...
Donc ceci devrait te convenir : 
<?php

$inpresult = !empty($_POST['inpresult']) ? $_POST['inpresult'] : NULL;

if($inpresult){
  
  echo "<script type='text/javascript'>
   alert('".$inpresult."');
  </script>";
  
}


?>

NB: Encore une fois... tes explications n'étaient clairement pas assez précises ni comprensibles.... Il faut vraiment se triturer les méninges pour essayer de te comprendre... Il serait bien que tu commences à faire des efforts.
Ca fait déjà pas mal de temps que tu postes des questions sur ce forum.. et à chaque fois c'est la même galère pour te comprendre :-)
