Knockoutjs可见的||绑定 要么？

Question

I want to do something basic like:

data-bind="visible: x || y"

showing if either x or y is set to true

Everything I've tried has failed so far though.

Answer 1

如果x和y是可观察的属性，则需要将它们作为方法调用：

data-bind="visible: x() || y()"

Answer 2

当在这样的公式中使用可观察变量时，您需要将它们称为函数。

data-bind="visible: x() || y()"
