knockout.js - 具有约束力的淘汰赛

Question

我在敲除“With”绑定时遇到问题。我可以绑定。我可以绑定嵌套对象没问题，但不能绑定嵌套模型。我做错了还是这超出了“with”绑定的范围。

var viewModel = function(){
    var self = this;

    self.anObject = {
        test: ko.observable("I'm and object bound by WITH.")   
    }

    var aFunction = function (){
        var self = this;
        self.test = ko.observable("I would like to be bound by WITH");   
    }

};
ko.applyBindings(new viewModel());

var viewModel = function(){
    var self = this;

    self.anObject = {
        test: ko.observable("I'm and object bound by WITH.")   
    }

    var ViewModel2 = function (){
        var self = this;
        self.test = ko.observable("I would like to be bound by WITH");   
    };

    self.aFunction = new ViewModel2();

};
ko.applyBindings(new viewModel());
