Java Script failed to create QtQuick 2.5 object

SandyMedical

I am creating QT object in Java script & emitting signal from JavaScript to QML Slot.

My work Environment : Qt 5.8 MSVC2015 64bit, Windows 7 64 bit.

Java Script code :


   var internalQmlObject = **Qt.createQmlObject('import QtQuick 2.5; QtObject{ signal someSignal(int value) }', Qt.application, 'InternalQmlObject')**;
    function runNow(){
        internalQmlObject.someSignal(42);
    }

Code of QML :

import QtQuick 2.5
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.0
import QtWebEngine 1.4
import "testJava.js" as Helper


     ApplicationWindow {
        width: 1024
        height: 750
        visible: true
    
        WebEngineView {
            id: webEngine
            anchors.fill: parent
            url: "qrc:/TestPage.html"
    
            function someSlot(v) {
                console.log("Signal received " + v);
            }
    
            onLoadingChanged: {
                Helper.internalQmlObject.someSignal.connect(someSlot);
            }
        }
    }

But Java Script failed to create QtQuick 2.5 object:

Application log :
D:\task\QT_Test\build-testURL-Desktop_Qt_5_8_0_MSVC2015_64bit-Debug\debug\testURL.exe...

js: Uncaught ReferenceError: Qt is not defined

[4492:5796:0427/113341:INFO:CONSOLE(1)] "Uncaught ReferenceError: Qt is not defined", source: qrc:/testJava.js (1)

you can find my code

Any suggestion why JavaScript failed to identify QT?

you can find my code

I found the issue, in HTML page, I am loading testJava.js, which causing this issue : <head> <script type="text/javascript" src="testJava.js"></script> </head>

But still why it should have an issue ?
