本文实例讲述了javascript弹出带文字信息的提示框效果。分享给大家供大家参考，具体如下：

tooltips.js:

// position of the tooltip relative to the mouse in pixel //
var offsetx = 12;
var offsety = 8;
function newelement(newid)
{
  if(document.createElement)
  {
    var el = document.createElement('div');
    el.id = newid;
    with(el.style)
    {
      display = 'none';
      position = 'absolute';
    }
    el.innerHTML = ' ';
    document.body.appendChild(el);
  }
}
var ie5 = (document.getElementByIdx && document.all);
var ns6 = (document.getElementByIdx && !document.all);
var ua = navigator.userAgent.toLowerCase();
var isapple = (ua.indexOf('applewebkit') != -1 ? 1 : 0);
function getmouseposition(e)
{
  if(document.getElementByIdx)
  {
    var iebody=(document.compatMode &&
    document.compatMode != 'BackCompat') ?
    document.documentElement : document.body;
    pagex = (isapple == 1 ? 0:(ie5)?iebody.scrollLeft:window.pageXOffset);
    pagey = (isapple == 1 ? 0:(ie5)?iebody.scrollTop:window.pageYOffset);
    mousex = (ie5)?event.x:(ns6)?clientX = e.clientX:false;
    mousey = (ie5)?event.y:(ns6)?clientY = e.clientY:false;
    var lixlpixel_tooltip = document.getElementByIdx('tooltip');
    lixlpixel_tooltip.style.left =(mousex+pagex+offsetx) + 'px';
 lixlpixel_tooltip.style.top =(mousey+pagey+offsety) + 'px';
  }
}
function tooltip(tip)
{
  if(!document.getElementByIdx('tooltip')) newelement('tooltip');
  var lixlpixel_tooltip = document.getElementByIdx('tooltip');
  lixlpixel_tooltip.innerHTML = tip;
  lixlpixel_tooltip.style.display = 'block';
  document.onmousemove = getmouseposition;
}
function exit()
{
  document.getElementByIdx('tooltip').style.display = 'none';
}

test.html

<html>
<head>
<style>
.tableBorder7{width:800;solid; background-color: #000000;}
TD{font-family: 宋体;font-size: 12px;line-height : 15px ;}
th{background-color: #f7f7f7;color: #000000;font-size: 12px;font-weight:bold;}

<script language="JavaScript" src='tooltips.js'>
</script>
</HEAD>
<BODY>
<div onmouseover="tooltip('如果你添加的是一个播客（Podcast），请选中此复选框。');"onmouseout="exit();">蝶恋花</div>
