Comme vous le savez, L'option "Autoriser le zoom" permet à l'utilisateur de modifier le zoom en écartant/resserrant les doigts.

Mes questions :
1. Comment fait-on pour récupérer la valeur du zoom ?
Z. Comment modifier le zoom par programmation ?

Pour la détection du zoom, j'ai trouvé ce code JavaScript qui fonctionne sur tous les navigateurs.
<!DOCTYPE html>
<html dir="rtl">
<head>
<meta charset="utf-8" />
<title>WXFAKI</title>
<style type="text/css">
html{color:#000;background:#FFF;}</style>
<script type="text/javascript"/>

function supportFullCss3()
{
var div = document.createElement("div");
div.style.display = 'flex';
var s1 = div.style.display == 'flex';
var s2 = 'perspective' in div.style;

return (s1 && s2);
};

function getZoomLevel()
{
var screenPixelRatio = 0, zoomLevel = 0;

if(window.devicePixelRatio && supportFullCss3())
screenPixelRatio = window.devicePixelRatio;
else if(window.screenX == '0')
screenPixelRatio = (window.outerWidth - 8) / window.innerWidth;
else
{
var scr = window.frames.screen;
screenPixelRatio = scr.deviceXDPI / scr.systemXDPI;
}

//---------------------------------------

Maintenant je cherche a modifier le zoom sur Android et iOS.
Sur Android , je sais que cela utilise le Webview et sur iOS UIWebView - UIKit
Si vous avez des bouts de codes même en Java ou Objective C , Je suis preneur.

Ton post date de plus d'un an mais il m'a bien aidé, je te dis un grand merci pour avoir publié ta solution, ce bout de code javascript qui m'a permis d'activer le zoom je n'arrive pas activer sur les champs html dans android.
