Several states of vue intersection

In the field of front-end development, Vue is a very popular framework. Vue can help developers complete front-end development work in a more reasonable and efficient way, thereby improving work efficiency and code quality. However, some intersection states will appear in Vue development. These states may affect the use of Vue, and developers need to pay more attention in actual development.

Let’s discuss several states of Vue intersections.

1. Initial state

The initial state of Vue refers to the initial state of the Vue instance when the Vue instance is created. In the initial state, all data of the Vue instance is empty and there is no data binding. In this state, developers need to use the data binding method provided by Vue to bind data to the Vue instance, so that the Vue instance can correctly obtain the data and operate it.

2. Loading state

Loading state refers to the state encountered when loading data in a Vue component or route. In this state, the Vue instance is loading data and may display some animation effects or loading status to let the user know that the data is loading.

In development, we usually call asynchronous interfaces to obtain data during the created or mounted life cycle of components or routes to solve the separation requirement of data and templates. During these asynchronous interface requests, the component or route may be unable to present data that can be interacted with the user for a time. At this time, such components become loaded.

3. Error status

Error status refers to the status encountered when an error occurs in a Vue component or route. Error states occur when data in a component or route cannot be loaded or manipulated correctly. In this state, the Vue instance is not functioning properly and the page may need to be manipulated to fix errors.

In addition to the above operational errors, we still have some unforeseen exception errors that need to be captured and processed in time, otherwise the Vue application may crash. Therefore, we recommend that developers write error handling methods when writing front-end code, and global methods such as extend should not have the effect of throwing exceptions.

In general, Vue’s intersection status is nothing more than the above three types, which are closely related to business development. In actual development, developers can improve the use of Vue by properly handling intersection status, making Vue instances more robust and stable.
