Javascript overwriting of prototype method leads to type error

[mraalex]

Hi,
MCAddition is overwriting function protoype.getChallengeName from MC. But when I call the method in QML I can an error saying "TypeError: Type Error".

What am I doing wrong?

============== File MC.js ====================
.pragma library

Qt.include("../Common.js")

function MC() {

}

MC.prototype.getChallengeName=function() {
return "N";
}

============== File MCAddition.js ====================
.pragma library

Qt.include("MC.js")

MCAddition.prototype=new MC();
MCAddition.prototype.constructor=MCAddition;

function MCAddition() {

}

MCAddition.protoype.getChallengeName=function() {
return "A";
}

============== File main.qml ====================
...
Button {
id: button1
x: 0
y: 0
width: parent.width/2
height: parent.height/2
text: "1"
onClicked: {
var MC=new MC.MCAddition();
var challengeName=MC.getChallengeName();
}
}

Hi,

Did you import the js file in QML ?
Like for eg.
@
import "logic.js" as Logic
@

Yes, import "MCAddition.js" as MC
