Let’s talk about how vue prevents H5 history from refreshing the page

With the popularity of web applications, front-end frameworks have become the first choice for developers. Vue is one of the popular frameworks that allows developers to build single-page applications, improving user experience and smoothness. However, many developers may encounter a problem, that is, how to prevent H5 history from refreshing the page. This article will introduce you to how to solve this problem in an H5 web application using Vue.js.

In Vue.js, we can use "routing" to solve this problem. Routes can be defined in Vue.js, allowing us to implement single-page applications in H5 web applications. Routing tells the page which component should be displayed at which URL. In this way, we can simulate changes to the page content by changing this URL instead of refreshing the entire page. Therefore, routing in Vue.js hides most of the implementation details of the website and provides a better user experience.

Before learning how to prevent H5 history from refreshing the page, we need to implement routing in Vue.js first. We will use the vue-router library, which is one of the official libraries for Vue.js. First, we need to install this library in our project. We can use npm or yarn, enter the following command in the command line:

npm install vue-router

yarn add vue-router

After installing vue-router, we need to import it in our Vue.js application and use it to define the application routing. In the following example, we will create a route to display the home page, login page, and registration page.

import VueRouter from 'vue-router';

Vue.use(VueRouter);

const routes = [
    { path: '/', component: HomePage },
    { path: '/login', component: LoginPage },
    { path: '/register', component: RegisterPage }
];

const router = new VueRouter({
    routes
});

In the above example, we use VueRouter to import routes in Vue.js and use it to define the path to the application. These paths specify which component the application should use to display the page. In this example, we have defined three paths: home page, login page, and registration page. Now we can use these paths in our Vue.js application instead of changing the entire page.

Now that we have defined our website using vue-router, next, we will use Vue.js and HTML5's history API to prevent H5 history from refreshing the page. HTML5's History API provides a way to change the URL of a page without refreshing the entire page. Using HTML5's history.pushState() method, we can change the URL and add it to the browser's history without refreshing the entire page. We can use this in Vue.js components to update the URL.

In the following example, we will see how to use HTML5's history.pushState() method in Vue.js to prevent H5 history from refreshing the page. We'll call this in Vue.js's lifecycle mount function to ensure it's called when the page loads.

export default {
    mounted() {
        const path = window.location.pathname;
        history.pushState({ path }, '', path);
    }
}

In the above example, we called the history.pushState() method in the Vue.js life cycle hook. We add the URL to the history and return an object to the method containing the path we defined. Now we can update the URL without refreshing the entire page.

In this article, we learned how to use Vue.js’ routing and HTML5’s history API to prevent H5 history from refreshing the page and improve the performance and user experience of the website. To achieve this, we used the vue-router library and the Vue.js life cycle hook to call the HTML5 history.pushState() method. Now, we can use Vue.js to develop better H5 website applications without refreshing the entire page.
