Aurelia阵列观察对array [index] = newItem不起作用 [英] Aurelia array observation doesn't react on array[index] = newItem

问题描述

我很惊讶为什么我的repeat.for绑定不对数组更改做出反应.然后我发现Aurelia阵列观察结果对array [index] = newItem没有反应.

I use surprised why my repeat.for binding doesn't react on array change. Then I found out Aurelia array observation doesn't react on array[index] = newItem.

这是我阅读规范时确认的 https://github.com/aurelia/binding/blob/master/test/array-observation.spec.js

This is confirmed when I read the spec https://github.com/aurelia/binding/blob/master/test/array-observation.spec.js

数组观察仅对pop/push/reverse/shift/sort/splice/unshift方法起作用.替换整个数组也可以.

The array observation only reacts on methods pop/push/reverse/shift/sort/splice/unshift. Replacing the whole array works too.

我可以使用splice而不是使用array[index] = newItem来解决我的问题；

I can fix my issue with splice instead of using array[index] = newItem;

但是我想知道对于Aurelia阵列观察，对array[index] = newItem做出反应在技术上是否太困难了?

But I would like to know is it technically too difficult to react on array[index] = newItem for Aurelia array observation?

推荐答案

Aurelia官方不支持此功能.

This is offcially unsupported in Aurelia.
