访问viewModel属性

Question

是否可以随时在页面上的任何脚本中访问viewModel属性？在下面的模型中，我想使用currModel作为存储某个标志的地方，我可以不将它绑定到DOM中的某些内容吗？感谢任何帮助。

function viewModel(result,currentTheme) {
    var self = this;
    self.isBlankForm = !(result.payload.isBlankForm);
    self.snapEdit = result.payload.emailText;
    self.snapEditSuccess = result.payload.successBody;
    self.isMeNotified = result.payload.isMeNotified;
    self.isEmailSentToUser = result.payload.isEmailSentToUser;
    self.fromEmailBox = result.payload.fromUserEmail;
    self.subjectEmailBox = result.payload.emailSubject;
    self.themeNames = ko.observableArray(result.payload.themeList);
    self.themeChoice = ko.observable(self.themeNames.find("id", currentTheme));
    self.bgColor = result.payload.bgColor;
    self.frmColor = result.payload.frmColor;
    self.txtColor = result.payload.txtColor;
    self.btnColor = result.payload.btnColor;
    self.btnTxtColor = result.payload.btnTxtColor;
    self.currModel = ko.observable();
}

当然，只需将您的VM存储在变量中即可。

例如：

var myVM = new viewModel(); 
ko.applyBindings(myVM);

现在，您可以随时访问myVM.currModel()。
