Question

jquery里面，有9张图片，触发单击事件后，怎么取得具体某张图片的id?

jquery代码：$().ready(function(){    $("#head img").click(function(){         $(this).css({border:"solid 1px #CCCCCC"});         var dis=$("#hidediv").css("display");         if(dis=="none"){             $("#hidediv").show();         }else{             $("#hidediv").hide();             $(this).css({border:"solid 1px #72B9F1"});         }    });    });html代码：<div id="head">            <img src="../image/1.jpg" id="img1"/>            <img src="../image/2.jpg" id="img2"/>            <img src="../image/3.jpg" id="img3"/>            <img src="../image/4.jpg" id="img4"/>            <img src="../image/5.jpg" id="img5"/>            <img src="../image/6.jpg" id="img6"/>            <img src="../image/7.jpg" id="img7"/>            <img src="../image/8.jpg" id="img8"/>            <img src="../image/9.jpg" id="img9"/>  </div>截图：注：看清是#head img(head里面的img)单击事件，这样子做，怎么把他取得的图片id得出？
