<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>实现两边固定宽度,中间自适应宽度-</title> 
 <script src="jquery-2.2.3.min.js"></script>
  <script src="style.js" type="text/javascript"></script>
</head> 
 
<body> 
      <div class="a"> 鼠标移到A上  </div>

      <div class="b" style="display:none;"> A 显示出来 </div>
    
</body> 
</html>

         JS代码:

       var isHover = false;
     $(function() {
    $(".a").hover(function() {
        isHover = true;
        $(".b").show();
    }, function() {
        isHover = false;
        setTimeout(function() {
            if (!isHover) {
                $(".b").fadeOut();
            }
        }, 10);
    });
    $(".b").hover(function() {
        isHover = true;
