IE 9 détection de flash avec javascript

Question

Vérification de la présence du plugin flash, uniquement dans IE (pensez essentiellement à IE javascript engine, même lorsque le mode de navigation du navigateur & a été modifié avec les outils de développement).

var is_Flash = false; 
var is_FlashVersion = 0; 

var plugin = (navigator.mimeTypes && 
       navigator.mimeTypes["application/x-shockwave-flash"] && 
       navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin) ? 
       navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin : 0; 
if (plugin&&plugin.description) { 
    is_Flash = true; 
    is_FlashVersion = parseInt(plugin.description.substring(plugin.description.indexOf(".")-1)); 
} 

IE ne retourne pas les détails du plugin. Quelqu'un connaît une solution?

Peut l'utiliser pour vérifier les détails de l'objet, IE simplement rien et 0 longueur sur l'objet mimeTypes.

var obj = navigator.mimeTypes["application/x-shockwave-flash"]; 
var out = ''; 
for (var i in obj) { 
    out += i + ": " + obj[i] + "\n"; 
} 
alert(out);

Vous devez regarder ActiveXObjects dans ie.

j'ai écrit cette petite fonction d'un certain temps, vous pouvez peut-être obtenir un peu d'inspiration de celui-ci, je ne l'ai pas testé dans IE9 however.-

function hasFlashVersionOrBetter(major, minor) { 
    minor = minor || 0; 
    var v; 
    if (navigator.plugins && navigator.plugins.length > 0) { 
     var type = 'application/x-shockwave-flash'; 
     var mimeTypes = navigator.mimeTypes; 
     if (mimeTypes && mimeTypes[type] && mimeTypes[type].enabledPlugin && mimeTypes[type].enabledPlugin.description) { 
      v = mimeTypes[type].enabledPlugin.description.replace(/^.*?([0-9]+)\.([0-9])+.*$/, '$1,$2').split(','); 
     } 
    } 
    else { 
     var flashObj = null; 
     try { flashObj = new ActiveXObject('ShockwaveFlash.ShockwaveFlash'); } catch (ex) { return false; } 
     if (flashObj != null) { 
      var fV; 
      try { fV = flashObj.GetVariable("$version"); } catch (err) { return false; } 
      v = fV.replace(/^.*?([0-9]+,[0-9]+).*$/, '$1').split(','); 
     } 
    } 
    if (v) { 
     var majorVersion = parseInt(v[0], 10); 
     return major > majorVersion || major == majorVersion && minor >= parseInt(v[1], 10); 
    } 
    return false; 
}

Pourquoi réinventer la roue et ont des maux de tête: Utilisation cette bibliothèque JS légère.

Vous pouvez détecter les versions flash ou Flash facilement, sans aucun problème croix navigateur,

Merci les gars pour la réponse, mais mon co-développeur trouvé un beau morceau de code en adobe qui fonctionne pour tous navigateurs.

Answer 4

 if (navigator.plugins && navigator.plugins.length > 0) { 
      var type = 'application/x-shockwave-flash'; 
      var mimeTypes = navigator.mimeTypes; 
      if (mimeTypes && mimeTypes[type] && mimeTypes[type].enabledPlugin && mimeTypes[type].enabledPlugin.description) { 
       //Flash Object found. 
      } 
     } 

Le code ci-dessus travaille dans tous les navigateurs.
