The on-change event of the [Bug Report] Checkbox Group component cannot receive an array of all options currently selected

[AILINGANGEL]

Environment

Darwin Kernel Version 16.7.0/ chrome 72.0.3626.12 (64位)/ vue 3.3.2

Reproduction link

Steps to reproduce

点击选中多个checkbox选项

What is expected?

希望点击一个checkbox的时候，当前整个checkbox group中所有选中的选项都alert出来!!!

What is actually happening?

CheckboxGroup组件的on-change事件只有在使用了v-model双向绑定值的时候才会收到当前所选项的数组,单纯的使用:value或者不使用:value只绑定一个on-change事件只能收到当前点击过的选项，无法收到所有的选项。

Translation of this issue:

Environment

Darwin Kernel Version 16.7.0/ chrome 72.0.3626.12 (64 bits)/ Vue 3.3.2

Reproduction link

https://run.iviewui.com/McEY13pA

Steps to reproduce

Click to select multiple checkbox options

What is expected?

When you want to click on a checkbox, all the selected options in the current real checkbox group are alert!!!

What is actually happening?

The on-change event of the Checkbox Group component receives the currently selected array only when the bi-directional binding value of V-model is used. Simple use: value or no use: value only binds an on-change event to receive only the currently clicked option, not all the options.

这个功能没有比加一个v-model方便的吧？ 加参数跟加v-model好像没啥差

这不是新功能呀。就是说在ChecboxGroup这个组件上如果不使用v-model那么on-change事件接受到的值并不是当前group所有选中的项目,只是你点击的谁就收到谁,如果取消点击谁收到的还是[""]。这是个bug
