$(function(){  var url="http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?"   //使用getJSON方法取得JSON数据  $.getJSON(　　  url,  //处理数据 data指向的是返回来的JSON数据  function(data){    //生成标题和标题连接    var tit="<a href='"+ data.link +"'>"+data.title +"<//a>";    $("h1").html(tit); 　　    //出现在指定位置H1 内    $("#ginfo").find("p").eq(0).html(data.modified);    $("#ginfo").find("p").eq(1).html(data.generator);    var lis=""; 　    //li 列表项目    $(data.items).each(function(i,ite){ 　     //遍历JSON数据得到所需形式     lis+="<li>";     lis+="<a href='"+ ite.link +"'><img src='"+ite.media.m +"' title='"+ ite.title +"'><//><//a>";     lis+="<div>";     lis+=ite.description;      lis+="<//div><//li>";       })    $("ul").html(lis);     //将遍历出来的数据呈现在所需位置    $("li").hover(function(){$(this).addClass("hov")}, function(){$(this).removeClass("hov")});   }  ) }) 

<div class="main"> <div class="ginfo" id="ginfo">   <h1></h1>  <p></p>  <p></p> </div> <ul>   </ul></div>
