为什么从模特中获取＆＃39;不行？

Question

这两个记录有什么区别？它们应该同样有效。

<span data-bind="text: fullName"></span>
<script>
var viewModel = kendo.observable({
    firstName: "John",
    lastName: "Doe",
    fullName: function() {
        //return this.firstName + " " + this.lastName;
        return this.get("firstName") + " " + this.get("lastName");
    }
});

kendo.bind($("span"), viewModel);
</script>

Answer 1

获取和设置方法对于MVVM framework至关重要。它们用于通知ui应用了viewmodel的更改。
