Vue 2-如何在props中设置数组的默认类型 [英] Vue 2 - How to set default type of array in props

问题描述

我有我的Vue组件，该组件将一组对象作为道具.我经常使用道具验证，尤其是对于默认"值功能.

I have my Vue component, which is taking an array of objects as a prop. I often use prop validation, especially for 'default' value feature.

在这种情况下，我有:

props: {
    items: Array
}

但我希望它在Typescript或React中具有以下效果:

but I'd like it to have like in Typescript or React:

props: {
    items: Array.of(
        {key: {type: String, default: 'myText'}}
        )
}

等

有可能实现吗?否则，我只需要使用计算数据作为映射即可设置默认值

Is it possible to achieve? Otherwise I need to use computed data as map just to set the defaults

推荐答案

我创建了示例: jsFiddle ，这可能会对您有所帮助，是的...您可以将默认值作为数组返回:

I created example: jsFiddle, that might can help you, and yes... you can return the default value as a array:

ES6

props: {
    items: {
        type: Array,
        default: () => []
    }
}
