需要使用一个组件中的复选框过滤数据，这里的数据来自另一组件中的axios

Question

I am able to get the data from axios in one component but failing to filter it in checkbox on click event. I am struggling with how to transfer axios data to another component, which is parent and which is child?

I had created checkboxes in child component and data from axios in parent component trying to add event in child component checkbox to filter data according to colors in my parent data

Answer 1

使用Vuelidate验证输入。

Answer 2

Need to add eventBus to instance and call at data change, and use that emit when we need use the changed data.
