upgradeSearchOnWebkitBrowsers


 / Published in: JavaScript
 

  1. /*
  2. upgradeSearchOnWebkitBrowsers function makes the search
  3. input boxes in an HTML form appear and behave like
  4. search fields in Mac OS X applications.
  5. The function first looks if the page contains any forms
  6. then looks for an input field that has the name="search"
  7. attribute. When such input is found, it injects three
  8. new attributes that make Webkit browsers (such as Safari
  9. and OmniWeb) show the goodie.
  10. JavaScript is used to do this since these particular attributes
  11. are not standard HTML and will break the validation.
  12. All non-Webkit browsers should ignore the attributes
  13. and display the regular input box.
  14.  
  15. Dependencies:
  16.  - addLoadEvent (http://snipplr.com/view/1679/addloadevent/)
