Question

A model in my code receives a constructor at some point:

this.defaultView = WJCard;

WJCard is a simple prototype:

function WJCard() {...}

At some point, the model needs to create a WJCard instance based on the this.defaultView property.
I thought the following would help, but I’m wrong:

WJModel.prototype.render = function(classname) {

if (classname) {
    this.view = this.defaultView.call(); // Returns null :(
    // ...
}

    /. ...

}

I’ve tried a bit of everything with no success. Can anybody help me?

Corrected code thanks to answer…

WJModel.prototype.render = function(classname) {

if (classname) {
    this.view = new classname(); // works fine this way!
    // ...
}

    /. ...

}

You can still use new as usual:

this.view = new this.defaultView();
