Load plugin with js but "<embed>"

[FamousHe]

I want to load a plugin with js but html flag "<embed>".
In ie,we can use "new ActivexObject(...)" to load an activex.
Is there anyway to define a js function like it to load a plugin in cef3?

function CardReader(id){
this.id = id;
var objBody = document.getElementsByTagName("body").item(0);
this.object = document.createElement('object');
this.object.setAttribute("id",id,0);
this.object.setAttribute("type","application/x-alpaca-cardreader",0);
this.object.setAttribute("width",0,0);
this.object.setAttribute("height",0,0);
document.body.insertBefore(this.object,document.body.firstChild);
}

var cardReader = new CardReader("IDC30")
