Fusion(打字稿2):如何从父对象访问变量?

问题描述

这是

如果在下面的示例中定义了一个名为myLocalVar的局部变量，那么如何从其他对象(在本例中为Neos.Fusion:Case)访问它呢?

If I define a local variable, called myLocalVar in the example below, how can I access it from other objects, in this case from Neos.Fusion:Case?

prototype(Some.Namespace:SomeNodeType) < prototype(TYPO3.Neos:Content) {
    myLocalVar = ${String.split(q(node).property('example'), '/', 2)}

    myResult = Neos.Fusion:Case {
        a = Neos.Fusion:Matcher {
            condition = ${???.myLocalVar[0] == 'aaa'}
            renderer = 'first part is aaa'
        }
        b = Neos.Fusion:Matcher {
            condition = ${???.myLocalVar[0] == 'bbb'}
            renderer = 'first part is bbb'
        }
    }
}

在这个具体示例中:如何从Neos.Fusion:Matcher内部访问myLocalVar?

In this concrete example: How can I access myLocalVar from inside Neos.Fusion:Matcher?

有问题的部分是条件:condition = ${???.myLocalVar[0] == 'aaa'}

The part in question is the condition: condition = ${???.myLocalVar[0] == 'aaa'}

推荐答案

您需要将myLocalVar定义为上下文变量:

You need to define your myLocalVar as context variable:

@context.myLocalVar = ${String.split(q(node).property('example'), '/', 2)}

上下文是所有嵌套对象继承的，因此您可以像这样访问值

the context is inherited by all nesting objects, so you can just access the value like this

a = Neos.Fusion:Matcher {
    condition = ${myLocalVar[0] == 'aaa'}
    renderer = 'first part is aaa'
}
