实现简单提示条的两种方法：

<script>
<!–

function runcode(id){  //定义运行代码的函数，
  var code=event.srcelement.parentelement.children[id].value;//即要运行的代码。
  var newwin=window.open(,,);  //打开一个窗口并赋给变量newwin。
  newwin.opener = null
  newwin.document.write(code);  
  newwin.document.close();

}
//–>
</script>

<textarea  cols=95 rows=12>
<style type="text/css">

td,body{font:14px}
.article {
border-bottom: black 1px solid; border-left: black 1px solid; border-right: black 1px solid; border-top: black 1px solid; filter: revealtrans(transition=23,duration=0.5) blendtrans(duration=0.5); position: absolute; visibility: hidden
