Discuss methods of assigning attributes to Vue subcomponents

Vue is a popular JavaScript framework that makes it quick and easy to build reusable components in web applications. It implements component extension through reactive programming model and template syntax. This article aims to explore the method of assigning properties to Vue subcomponents.

Vue subcomponent

A Vue application consists of one or more components. Vue components follow a hierarchical structure, starting with a root component and then breaking down into smaller components, forming a hierarchical component structure. In Vue, data transfer between components is completed through parent-child component communication.

A child component is a component called by a parent component. Parent components can configure child components by passing properties to them.

Vue Subcomponent Property Assignment

Vue provides a convenient method to pass data to subcomponents through property passing. Parent components can pass data to child components through props. Child components can obtain data from parent components by declaring the props they want to accept.

For example:

In the parent component App.vue:

In the child component Child.vue:

In the above code, we can See that the child component Child defines two properties, name and age, through props. This property definition allows the property to pass data from the parent component to the child component. The parent component App.vue passes data to the child component Child.vue through property binding, which can be done in the following ways:

At this time, the child component Child.vue will be able to obtain it from the parent component App.vue The data of attribute name and attribute age.

Conclusion

In Vue, the parent component can pass data to the child component through attribute passing, and the child component can obtain the data from the parent component by declaring the attributes to be accepted. This article mainly introduces the method of assigning properties to Vue subcomponents. I hope that the introduction in this article will help you become more proficient in using Vue.
