<style type="text/css"> 
* { margin: 0; padding: 0;}

</style> 
<script src="js/jquery.js" type="text/javascript"></script> 
<script type="text/javascript"> 
function findit(msg){ 
  var logStatus = 0; 
  if(msg==2) 
  checkWin(logStatus); 
} 
function centerWin(){ 
  //center the Win to the center of screen 
  var windowWidth = document.documentElement.clientWidth, 
    windowHeight = document.documentElement.clientHeight, 
    scrollTop = document.documentElement.scrollTop, 
    scrollLeft = document.documentElement.scrollLeft, 
    popupWidth = $("#logWin").width(), 
    popupHeight = $("#logWin").height(); 
  $("#logWin").css({ 
    "display" : "block", 
    "position" : "absolute", 
    "top" : scrollTop + windowHeight/2 - popupHeight/2, 
    "left" : scrollLeft + windowWidth/2 - popupWidth/2 
  }); 
  //only need force for IE6 
  $("#bg").css({"height" : windowHeight}); 
} 
function checkWin(logStatus01) { 
  logStatus=logStatus01; 
  if (logStatus == 0) { 
    //if the window is disabled, enable the window 
    centerWin(); 
    $("#bg").css({"opacity":"0.5"}); 
    $("#bg").fadeIn("fast"); 
    logStatus = 1; 
  } else { 
    //disable the window 
    $("#bg").fadeOut("fast"); 
    $("#logWin").fadeOut("fast"); 
    logStatus = 0; 
  } 
} 
$(function() { 
    $("#no1,#no2,#no3,#no4").click(function(){ 
    var msg01=$(this).text(); 
     $("#role").append("<option selected='selected'>"+msg01+"</option>");
     $("#logWin").css({ 
      "display" : "", 
  });
      });
  });
</script> 
</head> 
<body> 
  <select name="role_select" style="width: 154px" id="role" class="login_input" 
   onchange="findit(this.options[this.options.selectedIndex].value)"> 
  <option value="1">******</option> 
  <option value="1">******</option> 
  <option value="2">输入</option>
</select>
<div id="logWin"> 
  <h2 id="点击你想输入的内容">点击你想输入的内容</h2> 
  <ul style="margin-left=10px; list-style:none;"> 
    <li id="no1">NO1</li> 
    <li id="no2">NO2</li> 
    <li id="no3">NO3</li> 
    <li id="no4">NO4</li>
