解决方案 »

  1.   

                <div id="overview">
                    <div class="title">
                        地图鸟瞰<span>Map Overview</span>
                        <img src="img/Download.png" alt="" />
                    </div>
                   ……………………
                   ……………………HTML如上……
      

  2.   

    代码本身看不出问题。你看看这句是否选中$("#introduceMain p")
      

  3.   


    <script src="js/jquery-1.3.2.js" type="text/javascript"> </script> 
    <script>
    $(document).ready(function(){ $("p").fadeIn("fast"); 
        $('#overview img').bind("click", function(){
            $("#introduceMain p").fadeOut("slow"); 
        }); 
    });
    </script>
               <div id="overview"> 
                    <div class="title"> 
                        地图鸟瞰 <span>Map Overview </span> 
                        <img src="img/Download.png" alt="" /> 
                    </div>
                </div>
    <div id="introduceMain"><p >xxxxxxxxxx</p></div>
