clear form field on first focus (inline version)

Published in: JavaScript 

The unobtrusive version requires an onload statement. Doing that in a backward-compatible fashion can be a pain in the ass. So here is an inline version for use with older code. This should work "out of the box" with any browser that has javascript.

Plain TextExpand 
  1. <script type="text/javascript">
  2. var Handler = {
  3.   clearedOnce : false,
  4.   clear : function ( field ) {
  5.     if (this.clearedOnce == false) {
  6.       field.value = '';
  7.       this.clearedOnce = true;
  8.     }
  9.   }
  10. }
  11. </script>
  12. <!-- then in the XHTML: -->
  13. <input onfocus="Handler.clear(this)" value="foobar" />
