Question

以下模板表达式给我以下编译错误

{{
    antiAffineRules.length > 0
        ? 'vm.affinity.rules' | translate : antiAffineRules.length
        : ""
}}

解析器错误：条件表达式{...}在表达式末尾需要所有3个表达式

奇怪的是，在开发模式下没有出现此错误，因此jit和aot编译器之间的行为一定是不同的。

我的版本为6.1.10

Answer 1

这是因为解析器被:所迷惑，()被用作将参数传递给管道以及三元运算符的第二部分的方式。

您可以添加{{ antiAffineRules.length > 0 ? ('vm.affinity.rules' | translate : antiAffineRules.length) : "" }}来帮助解析器
