How to make a new page display in vue layout

With the popularity of the Vue framework, more and more web developers are beginning to use it to develop comprehensive web applications. Vue's documentation and community are also constantly evolving to meet the changing needs of Vue users. However, for those who want to implement a complete layout in Vue, the most common question is how to make the new page display in the Layout. If you also encounter this problem, don't worry. This article will introduce some methods to solve it.

Vue.js uses many concepts, including components, templates and routing. These concepts make Vue development very flexible and easy to maintain. For page layout, Vue provides the concept layout. Layout is a component used to define the page layout, including the header, sidebar, bottom and main content area. In Vue, a layout is usually located in the App.vue component or similar root component and contains other child components.

In traditional web applications, when we click a link or submit a form, the server will serve a new page. But in Vue, we usually use Vue router. Vue Router is a tool that allows defining all possible paths in an application, and the components that correspond to these paths. This means that we can leverage Vue Router to open any component in the Vue application, rather than just loading a new HTML page.

Here are some Vue router methods to open new components:

1. router.push()

router.push() method allows us to open a new component from a A transition from one component to another, similar to clicking a link. For example:

this.$router.push('/dashboard');

This will navigate to the component named "Dashboard".

2. router.replace()

router.replace() method allows us to replace records in the current routing history without adding new history items. For example:

this.$router.replace('/dashboard');

This will navigate to the component named "Dashboard" and replace the current route history item.

3. router.go()

The router.go() method allows us to move forward or backward a specified number of steps in the history. For example:

this.$router.go(-1);

This will go one step back in history.

Use these methods in the Vue router to open new components in the layout. We can define a route view in the layout component to display the component in the layout view. Using this approach we ensure that every new page is opened within the layout.

The following is the code for a sample .vue file, which contains the layout component, main view and route view:

<template>
  <div id="app">
    <layout>
      <router-view />
    </layout>
  </div>
</template>

<script>
import Layout from './components/Layout.vue';

export default {
  components: {
    Layout
  },
};
</script>

In the above code, we first imported our layout component, and then Define it in the template. We also use route views in our definition. This view will be opened inside our component.

In order to define the path more clearly in the router, we need to include the following code in the router object:

const router = new Router({
  routes: [
    {
      path: '/',
      component: Home
    },
    {
      path: '/dashboard',
      component: Dashboard
    }
  ]
});

In the above, we defined two paths, one is /, and the other is is/dashboard. When a user accesses a URL, the Router will open either the Home component or the Dashboard component, depending on the URL the user accessed.

In a complete Vue application, other components can be added to the layout as above.

Summary

In Vue JS, the Layout component is a method of reasonably distributing elements in a web page. Using methods in Vue router, we can open new components inside the Layout component instead of loading them in separate pages. This can greatly speed up page switching and make web applications have a better user experience. After solving the above problems, I believe it will help you quickly develop high-quality Vue applications.
