Determining the Salesforce Style That Users See in JavaScript

If you use a lot of JavaScript in your pages and apps, identifying the Salesforce theme that a user sees in JavaScript code is important. Identifying the current user experience context allows you to correctly manage navigation in your JavaScript code.

The UITheme.getUITheme() JavaScript function returns a string containing one of the following values to identify the current user interface theme.

  • Theme1—Obsolete Salesforce theme
  • Theme2—Salesforce Classic 2005 user interface theme
  • Theme3—Salesforce Classic 2010 user interface theme
  • Theme4d—Modern “Lightning Experience” Salesforce theme
  • Theme4t—Salesforce mobile app theme
  • Theme4u—Lightning Console theme
  • PortalDefault—Salesforce Customer Portal theme
  • Webstore—AppExchange theme

The string values returned are the same values returned by the Visualforce $User.UITheme and $User.UIThemeDisplayed global variables.

The following markup checks if the current user experience context is the Lightning Experience theme.
