Preface
In modern web development, browser compatibility is an important issue. Although most users have turned to modern browsers, there are still some users who may still be using old browser versions. In order to improve the user experience and ensure the normal operation of the website functions, we can use the page header prompt to inform users that they need to upgrade their browser. This article will introduce in detail how to implement low-version browser upgrade tips in Vue project, and display different application scenarios and technical points through multiple code examples.
Basic concepts and functions descriptions
Browser compatibility
Browser compatibility refers to the consistency and functionality of web pages or web applications on different browsers and versions. Modern browsers such as Chrome, Firefox, Safari, etc. provide rich APIs and support the latest web standards, while older browsers such as IE8 and below may have many restrictions and incompatibility issues.
The meaning of the page header prompt
Page header tips are a common practice to remind users that the browser currently is using is lower and it is recommended to upgrade to the latest version for a better experience. This not only improves the user experience, but also reduces the problem of functional failure caused by browser incompatibility.
Example 1: Basic prompt function
First, let’s take a look at a basic prompt function example. We will detect the user's browser version and display the prompt message at the head of the page.
<template>
<div >
<div v-if="isOldBrowser" class="browser-warning">
You are using a lower version of the browser，It is recommended that you upgrade to the latest version for a better experience。
</div>
<div class="content">
<h1>Welcome to our website</h1>
<p>This is a sample page。</p>
</div>
</div>
</template>
<script>
export default {
data() {
return {
isOldBrowser: false
};
},
created() {
();
},
methods: {
checkBrowserVersion() {
const userAgent = ;
if (/MSIE [6-8]/.test(userAgent)) {
= true;
}
}
}
};
</script>
<style>
.browser-warning {
background-color: #ffcccc;
color: #a94442;
padding: 10px;
text-align: center;
border: 1px solid #ebccd1;
}
.content {
margin-top: 20px;
}
</style>
Code explanation

Example 2: Use Vuex to manage prompt status
In complex applications, prompt status may require cross-component management. At this time, Vuex can be used to centrally manage the state.
<template>
<div >
<div v-if="isOldBrowser" class="browser-warning">
You are using a lower version of the browser，It is recommended that you upgrade to the latest version for a better experience。
</div>
<div class="content">
<h1>Welcome to our website</h1>
<p>This is a sample page。</p>
</div>
</div>
</template>
<script>
import { mapState } from 'vuex';
export default {
computed: {
...mapState(['isOldBrowser'])
},
created() {
this.$('checkBrowserVersion');
}
};
</script>
<style>
.browser-warning {
background-color: #ffcccc;
color: #a94442;
padding: 10px;
text-align: center;
border: 1px solid #ebccd1;
}
.content {
margin-top: 20px;
}
</style>
Vuex Store Configuration
// store/
import Vue from 'vue';
import Vuex from 'vuex';
(Vuex);
export default new ({
state: {
isOldBrowser: false
},
mutations: {
setIsOldBrowser(state, value) {
= value;
}
},
actions: {
checkBrowserVersion({ commit }) {
const userAgent = ;
if (/MSIE [6-8]/.test(userAgent)) {
commit('setIsOldBrowser', true);
}
}
}
});
Code explanation
-
template:use
v-ifInstruction basedisOldBrowserThe value of the variable determines whether the prompt message is displayed. -
script: Using Vuex
mapStateHelper functions to access the state and increatedDistributed in the life cycle hookcheckBrowserVersionaction. - style: Define the style of prompt information and page content.
Example 3: Custom prompt style
To enhance the user experience, we can customize the style of the prompt message to make it more beautiful and eye-catching.
<template>
<div >
<div v-if="isOldBrowser" class="browser-warning">
<div class="warning-icon">⚠️</div>
<div class="warning-message">
You are using a lower version of the browser，It is recommended that you upgrade to the latest version for a better experience。
</div>
<div class="close-button" @click="dismissWarning">closure</div>
</div>
<div class="content">
<h1>Welcome to our website</h1>
<p>This is a sample page。</p>
</div>
</div>
</template>
<script>
export default {
data() {
return {
isOldBrowser: false
};
},
created() {
();
},
methods: {
checkBrowserVersion() {
const userAgent = ;
if (/MSIE [6-8]/.test(userAgent)) {
= true;
}
},
dismissWarning() {
= false;
}
}
};
</script>
<style>
.browser-warning {
display: flex;
align-items: center;
justify-content: space-between;
background-color: #ffcccc;
color: #a94442;
padding: 10px;
border: 1px solid #ebccd1;
}
.warning-icon {
font-size: 24px;
margin-right: 10px;
}
.warning-message {
flex-grow: 1;
}
.close-button {
cursor: pointer;
font-weight: bold;
color: #333;
}
</style>
Code explanation
- template: Use the Flexbox layout to arrange the parts of the prompt information and add a close button.
-
script:definition
dismissWarningMethod to close the prompt message. - style: Define the style of each part of the prompt message to make it more beautiful.
Example 4: Multilingual Support
In multilingual applications, prompt messages need to support multiple languages. We can usevue-i18nto implement multilingual support.
<template>
<div >
<div v-if="isOldBrowser" class="browser-warning">
<div class="warning-icon">⚠️</div>
<div class="warning-message">
{{ $t('') }}
</div>
<div class="close-button" @click="dismissWarning">{{ $t('') }}</div>
</div>
<div class="content">
<h1>{{ $t('') }}</h1>
<p>{{ $t('') }}</p>
</div>
</div>
</template>
<script>
import { createI18n } from 'vue-i18n';
const i18n = createI18n({
locale: 'en', // Default language messages: {
en: {
browserWarning: {
message: 'You are using an outdated browser. Please upgrade to the latest version for a better experience.',
close: 'Close'
},
welcome: {
title: 'Welcome to our website',
message: 'This is a sample page.'
}
},
zh: {
browserWarning: {
message: 'You are using a lower version of the browser, and it is recommended that you upgrade to the latest version for a better experience. ',
close: 'closure'
},
welcome: {
title: 'Welcome to our website',
message: 'This is a sample page. '
}
}
}
});
export default {
data() {
return {
isOldBrowser: false
};
},
i18n,
created() {
();
},
methods: {
checkBrowserVersion() {
const userAgent = ;
if (/MSIE [6-8]/.test(userAgent)) {
= true;
}
},
dismissWarning() {
= false;
}
}
};
</script>
<style>
.browser-warning {
display: flex;
align-items: center;
justify-content: space-between;
background-color: #ffcccc;
color: #a94442;
padding: 10px;
border: 1px solid #ebccd1;
}
.warning-icon {
font-size: 24px;
margin-right: 10px;
}
.warning-message {
flex-grow: 1;
}
.close-button {
cursor: pointer;
font-weight: bold;
color: #333;
}
</style>
Code explanation
-
template:use
$tMethod to get multilingual text. -
script: Import and configure
vue-i18n, define multilingual messages and use them in componentsi18nExample. - style: Define the style of each part of the prompt message.
Example 5: Combined with routing management prompt status
In multi-page applications, prompt status may need to be consistent across routes. We can combine Vue Router to manage prompt status.
<template>
<div >
<div v-if="isOldBrowser" class="browser-warning">
<div class="warning-icon">⚠️</div>
<div class="warning-message">
{{ $t('') }}
</div>
<div class="close-button" @click="dismissWarning">{{ $t('') }}</div>
</div>
<router-view></router-view>
</div>
</template>
<script>
import { mapState } from 'vuex';
export default {
computed: {
...mapState(['isOldBrowser'])
},
created() {
this.$('checkBrowserVersion');
},
methods: {
dismissWarning() {
this.$('setIsOldBrowser', false);
}
}
};
</script>
<style>
.browser-warning {
display: flex;
align-items: center;
justify-content: space-between;
background-color: #ffcccc;
color: #a94442;
padding: 10px;
border: 1px solid #ebccd1;
}
.warning-icon {
font-size: 24px;
margin-right: 10px;
}
.warning-message {
flex-grow: 1;
}
.close-button {
cursor: pointer;
font-weight: bold;
color: #333;
}
</style>
Vuex Store Configuration
// store/
import Vue from 'vue';
import Vuex from 'vuex';
import { createI18n } from 'vue-i18n';
(Vuex);
const i18n = createI18n({
locale: 'en', // Default language messages: {
en: {
browserWarning: {
message: 'You are using an outdated browser. Please upgrade to the latest version for a better experience.',
close: 'Close'
},
welcome: {
title: 'Welcome to our website',
message: 'This is a sample page.'
}
},
zh: {
browserWarning: {
message: 'You are using a lower version of the browser, and it is recommended that you upgrade to the latest version for a better experience. ',
close: 'closure'
},
welcome: {
title: 'Welcome to our website',
message: 'This is a sample page. '
}
}
}
});
export default new ({
state: {
isOldBrowser: false
},
mutations: {
setIsOldBrowser(state, value) {
= value;
}
},
actions: {
checkBrowserVersion({ commit }) {
const userAgent = ;
if (/MSIE [6-8]/.test(userAgent)) {
commit('setIsOldBrowser', true);
}
}
}
});
Routing configuration
// router/
import Vue from 'vue';
import VueRouter from 'vue-router';
import Home from '../views/';
import About from '../views/';
(VueRouter);
const routes = [
{
path: '/',
name: 'Home',
component: Home
},
{
path: '/about',
name: 'About',
component: About
}
];
const router = new VueRouter({
mode: 'history',
base: .BASE_URL,
routes
});
export default router;

Tips for using in actual work
Responsive design
On mobile terminals or under different screen sizes, the display method of prompt information may need to be adjusted. Media queries can be used to implement responsive design.
@media (max-width: 768px) {
.browser-warning {
font-size: 14px;
}
}
Dynamic prompt content
In some cases, prompt content may need to be generated dynamically based on the user's browser version. Dynamic prompt content can be implemented by calculating properties and methods.
Performance optimization
In the case of large amounts of data, frequent browser version detection may affect performance. Performance can be optimized through the caching mechanism.
Error handling
In actual development, various boundary situations need to be considered, such as the user disables JavaScript, etc. The user experience can be improved through conditional rendering and error handling.
User interaction
In order to make it easier for users to understand and operate prompt information, interactive elements such as icons, prompt text, etc. can be added in the prompt area.
