How to implement global Loading effects in Vue

In Vue development, implementing global Loading effects is a common requirement. The global Loading effect can give users a good prompt to let them know that the page is loading, improving the user experience. This article will introduce how to implement global Loading effects in Vue and provide specific code examples.

Create a global Loading component

First, we need to create a global Loading component. This component can be a simple loading animation, such as a rotating Loading icon. You can use third-party UI libraries, such as Element UI or the Loading component provided by Ant Design Vue. The following is an example:

Copy after login

In this component, we use theel-loadingcomponent provided by Element UI, and control the display and loading of Loading through thevisibleattribute hide.

Use the global Loading component in App.vue

Next, we need to use the global Loading component inApp.vue, and Show and hide it when needed. Communication between components can be achieved using Vue's event bus mechanism. The specific implementation is as follows:

Copy after login

In this example, we introduce the global Loading component and give it a name using therefattribute. In themountedhook function, we use the$onmethod of the event bus to listen to theshow-loadingandhide-loadingevents, and The corresponding callback function calls theshowandhidemethods of the global Loading component to show and hide the Loading.

Trigger the global Loading effect in other components

To trigger the global Loading effect in other components, we can use the$emitof the event bus Method to trigger theshow-loadingandhide-loadingevents. The following is an example:

Copy after login

In this example, we call the$emitmethod to triggershow-loadingand ## in the click events of the two buttons respectively. #hide-loadingevent, thereby triggering the display and hiding of the global Loading effect.

Through the above steps, we can achieve the global Loading effect in Vue. When the global Loading effect is needed, we only need to trigger the event in the corresponding component, and the global Loading component will be displayed, giving the user a good prompt. For specific effects, please refer to the actual running sample code.
