I. Why choose to manually set up multi-language?
As we all know.WordPress Plugin(such as WPML, Polylang) powerful, but not all projects are suitable for multi-language management through plug-ins, such as static sites, lightweight projects or sites with high performance requirements, etc., these cases manually set up multi-language through the HTML is more appropriate, the typical application scenarios include:
- Single page/landing page projects (without dynamically generated content)
- Low-cost projects (savings on plug-in fees)
- right SEO High control requirements (manual configuration) hreflang--For specifying the language and geolocation of web pages,Meta)
- Simple site supporting only 2~3 languages
Second, the core principle: through HTML tags and JavaScript to achieve language switching
The core idea is:
- Write content in different languages in advance
Put text in Chinese, English and other different languages in the web page. - "Language tagging" of content
Use class names or custom attributes to mark clearly what is Chinese and what is English. - Switching with JavaScript
When the user clicks the language button, theJavaScript Responsible for showing the corresponding language and hiding the others. - Do SEO at the same time
homepage<head>AddhreflangMarkup to let search engines know which page corresponds to which language, and to enhance the user experience with toggle buttons
HTML Multilingual Architecture Design Example
Assuming you want to support English (en) respond in singing Chinese (zh)The page structure code example is as follows:
<!-- 标题 -->
<h1 class="lang" data-lang="en">Welcome to My Website</h1>
<h1 class="lang" data-lang="zh">Welcome to my website.</h1>
<!-- 正文段落 -->
<p class="lang" data-lang="en">We offer high-quality services tailored to your needs.</p>
<p class="lang" data-lang="zh">We provide high quality services to fulfill your needs.</p>
<!-- 切换语言按钮 -->
<button onclick="switchLanguage('en')">English</button>
<button onclick="switchLanguage('zh')">Chinese</button>
JS Script Control Language Switching
{
el.style.display = el.dataset.lang === lang ? 'block' : 'none';
});
// Store the user selections
localStorage.setItem('selectedLang', lang);
}
// Automatically switch based on the user's last selection when the page loads.
window.onload = function() {
const savedLang = localStorage.getItem('selectedLang') || 'en';
switchLanguage(savedLang);
}; }
</script
Overview: Multiple copies of content (in different languages) are actually written on the page, and the JS script controls which language is displayed via buttons. The browser remembers which language the user has selected, avoiding the need to re-click each time.
