To determine the language code for a multi-language website with Weglot translation integration in Webflow, you can use the `getCurrentLang()` function provided by Weglot.
Here is a step-by-step guide on how to use `getCurrentLang()`:
1. Ensure that you have integrated Weglot with your Webflow website. You'll need to sign up for a Weglot account and follow their integration guide to add the Weglot script to your Webflow website.
2. Once Weglot is integrated, you can use the `getCurrentLang()` function to retrieve the current language code.
3. In your Webflow project, go to the page where you want to use the `getCurrentLang()` function. It could be a CMS template or a custom code embed on a specific page.
4. Add a custom code embed element to the desired page by dragging and dropping it from the Elements panel.
5. Double-click on the custom code embed element to open the code editor.
6. Inside the code editor, write your JavaScript code to use the `getCurrentLang()` function.
```javascript
```
7. Save the changes you made and publish your Webflow project.
Now, when you load the page, you should see the current language code logged in the browser's console. You can modify the code to use the language code in any way you need within your website's logic.
Note: Make sure to use the `getCurrentLang()` function after the Weglot script has loaded on the page. If you encounter any issues, check the Weglot documentation or reach out to their support for assistance.
