4) Add your new languages

You’ll then be prompted to enter the original language of your website + the new language(s) you want to translate and display your site into.



5) Copy and paste the code shown on your screen

This part is pretty easy. Copy the code that will appear on your screen (replacing “YOUR_API_KEY” with the one found in your Weglot setting).


Then paste it into the section of your HTML pages (if you’re using a CMS to build your website, this is usually located in the CMS settings, under a tab that will be titled “Custom Code” or something similar).

サイトをゼロから構築する場合は、すべてのウェブサイトのHTMLページで、タグの直前にJavaScript スニペットを貼り付けるだけです。

Your website is now translated!

You’ve now successfully translated your website using JavaScript. Go to your website and you’ll see a language switcher at the bottom right of your site (it might take a few minutes to appear). 

Weglot provides you with a first round of automatic translation, which you can then review and manually edit within your Weglot account dashboard under ‘Translations’. 


If you decide to install Weglot with this JavaScript integration, you’re all set for translating your site content, no matter what development stage you’re at.
