五 接收键盘指令的脚本:


 

  1. <SCRIPT language="JavaScript">
  2. <!--
  3. var hotkey=97
  4. var destination="http://www.wyev.com"
  5. if (document.layers)
  6. document.captureEvents(Event.KEYPRESS)
  7. function backhome(e){
  8. if (document.layers){
  9. if (e.which==hotkey)
  10. window.location=destination
  11. }
  12. else if (document.all){
  13. if (event.keyCode==hotkey)
  14. window.location=destination
  15. }
  16. }
  17. document.onkeypress=backhome
  18. //-->
  19. </SCRIPT>
  22. onkeydown="javascript:onenter();"
  24. function onenter(){
  25. if(event.keyCode==13){
  26. alert("回车");
  27. }
  28. }

六 让你的文本链接渐隐渐显:
