# Hooking into UI Javascript User Exits

Note: It is recommended to use UI Maps as alternatives to UI User Exits. Refer to the online documentation for UI Map information.
UI pages can have various events extended to add to or possibly override base product behavior. To create a Javascript user exit:

- Identify the page to extend.
- Create a JSP extension file (.xjs file) for the given page containing the necessary method for the given action.
- Identify user exits to code.
- Code the desired user exit logic into the JSP extension file.
