  1.   

     document.getElementById(tbox).style.display   参数，没有传递进去罢了建议还是这样document.getElementById("tbox").style.display =(document.getElementById("tbox").style.display!='none')?'none':'block'; 
      

  2.

  4.   

    div.style.visibility = '';
    　　这个地方错了：div.style.visibility = 'hidden';
    就可以了。
