I am using QT 5.5 version.

I need to invoke javascript callback function from QT plugin with Structure/Object as argument. I could not modify HTML Application since it is not in our scope.

HTML application code snippet

var obj1 = document.getElementById('obj1_id'); //QT plugin object 1
var obj2 = document.getElementById('obj2_id'); //QT plugin object 2
obj2.init(obj1,callback); //QT API
function callback(arg1)
if ( obj1 === arg1){

QT plugin code snippet

class::init(QWebElement obj, QString callback)
//need to Invoke callback with obj argument

Can any one help me on this?
