使用此数据： 我想使用 lodash 进行映射，如果打包为 0，则返回 false，如果为 1，则返回 true。

    canToggle(){
    _.map(this.parcels, function(status) { 
        var parcelState ; 

        status.packed === 0 ? parcelState = true : parcelState = false ; 

        return parcelState ; 
    });
},

并将其传递给我的组件道具，例如：

<delivery-parcel :parcel="parcel" :index="index" :packed="canToggle"></delivery-parcel>

所以在我传递的道具中：它会像：

props: ['packed','index','parcel'],

data(){
return { 

isPacked : this.packed

}

并在我的复选框中使用它，以便查看包裹是否已打包，以判断该特定包裹是否已打包。

    <v-checkbox @click="togglePacked" v-model="isPacked"></v-checkbox>              

Answer 1

我将假设packed 将是0 或1，而不是任何其他数字。 Vuejs 在控制台中分配 true 和 false 时存在问题，所以我建议这样做。创建一个计算属性来检查打包的变量值。

computed: {
   packStatus: function () {
     return this.packed !== 0 //this should return true if it's not 0, else return false
   }
}

然后你可以通过

传递计算方法的返回值

<delivery-parcel :parcel="parcel" :index="index" :packed=packStatus></delivery-parcel>
