如何在 Aurelia 中将 computedFrom 与多个属性一起使用
How to use computedFrom with multiple properties in Aurelia
问:
我有以下代码:
@computedFrom(['id', 'isDiscontinued'])
get disableAdd(){
return this.id === '0' || this.isDiscontinued;
}
这将引发以下错误:aurelia-binding.js:2580 Uncaught TypeError: this.input.charCodeAt is not a function
但是,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?

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