NPP_New not getting called in few webpages (Chrome and Safari)

StackOverflow https://stackoverflow.com/questions/15731240

Domanda

I am trying to access NPAPI plugin from content/inject script of Chrome/Safari extensions.

The code to embed the plugin object and access methods.

var newElement = document.createElement("embed");  
newElement.id = "myPluginID";  
newElement.type = "application/x-mychrome-plugin";
var newAttr = document.createAttribute("hidden");
newAttr.nodeValue = "true"
newElement.setAttributeNode(newAttr);
newElement.style.zIndex = "-1";
newElement.style.position = "absolute"; 
newElement.style.top = "0px";
document.documentElement.appendChild(newElement);
plugin = document.getElementById("myPluginID"); //this shows as HTML element when evaluated in JavaScript console.


   plugin.myPluginMethod() // this shows as undefined instead of native code(When evaluated in JavaScript console),for pages where NPP_New is not called.

This works for most of the webpages,but for few pages(eg:www.stumbleupon.com),NPP_New is not called(debugging using Xcode 4) and scriptable object is not created and all the plugin methods are undefined.

Any inputs.

È stato utile?

Soluzione

Why are you putting your embed as a child of document.documentElement (i.e., <html>) instead of in the body? I wouldn't expect a plugin that's not going to be displayed to be instantiated.
