Note: S-controls have been superseded by Visualforce pages. For more information, please visit S-Control_Deprecation

This S-control is an example of how to use AJAX and JavaScript to add functionality to a standard page.

It adds a "Related Contacts" pull-down list to the Contacts page, showing other contacts with the same email domain (eg @company.com). This is useful when you wish to find related contacts that might not be attached to the same Account.

  • Selecting a contact from the list will jump to that contact page.
  • A "Show All" option displays a search screen for all contacts with that email domain

This sample code demonstrates how to supplement a normal page with additional information, while maintaining a familiar user interface.


  • Create a new S-Control
  • Paste the code below directly into the S-control
  • Save the S-Control (Type: HTML)
  • Go to your Contact Page Layout
  • Drag the new S-Control onto the layout
  • Double-click the field, set Height to 22 and Tick "Show label"
  • Save
  • Make sure your Users have a Profile with ""API Enabled"" turned ON

To test: Go to a Contact that shares an e-mail address with another Contact (eg fred@gmail.com and jim@gmail.com). The pull-down menu should appear.

Want to exclude certain domains (eg msn.com)? Take a look at the related topic in the discussion forums.
