aurelia - 如何在 Aurelia 中使用具有多个属性的 computedFrom

Question

我有以下代码:

@computedFrom(['id', 'isDiscontinued'])
get disableAdd(){
    return this.id === '0' || this.isDiscontinued;
}

这会引发以下错误:aurelia-binding.js:2580 Uncaught TypeError: this.input.charCodeAt is not a function

然而这有效:

@computedFrom('id')
get disableAdd(){
    return this.id === '0' || this.isDiscontinued;
}

但是我需要两个 computedFrom 字段，我做错了什么？

Answer 1

@computedFrom('id', 'isDiscontinued')
get disableAdd(){
    return this.id === '0' || this.isDiscontinued;
}

不需要[]
