javafx - binding more than two property in fxml

Question

Suppose I want to bind disable property of a button with a checkbox's selected property. I know this method to bind them in FXML:

<Button disable="${firstcheckbox.selected}"/>

But what if I have two checkboxes and I want to bind the button's disable property with both the checkbox's selected property. Yes, I know I can do that in my java controller but I was just wondering if there is a way to do that in FXML.

If it's not clear what did I want, this is the Java code alternative to what I actually wanted:

mybutton.disableProperty().bind(firstcheckbox.selectedProperty().and(secondcheckbox.selectedProperty()));

Now I want to do this in FXML instead.

根据文档，您可以&&在表达式绑定中使用运算符。

由于&字符在 XML 中具有特殊含义，因此您需要对其进行适当的转义：一种方法是使用&来表示单个&字符。

<Button disable="${firstcheckbox.selected &amp;&amp; secondcheckbox.selected}"/>
