How to Customize Language Resources with Foxit PDF SDK for Web

Assumption

Assume you have an assets/in your website root directory, where you will configure the language resources. Let’s call this path as websiteRoot/assets/.

Configuration

1. Copy lib/locals inside the SDK to websiteRoot/assets/.
2. Set up the I18N path for loading resources.

   new UIExtension.PDFUI({
       i18n: {
           absolutePath: 'websiteRoot/assets/locals'
       },
       // the other options...
   });
   

3. Add more languages
   Create a new folder in websiteRoot/assets/locals. The folder name should follow the language codes standard, such as zh-CN for Chinese. And then new a file, name it as ui_.json and then translate the entries to your language. You can find the English resources inside the SDK package.
4. Set up default language

   new UIExtension.PDFUI({
       i18n: {
           absolutePath: `websiteRoot/assets/locals`,
           lng: 'zh-CN'
       }，
       // the other options
   })
   

Verify the configuration in a developer environment

1. Clear your browser caches to ensure the latest I18N resources will be loaded.
2. Refresh your browser, open the Network panel in DevTools,and check if the ui_.json request URL points your custom language path. If yes, then you’re all set!
