利用jQuery解析获取JSON数据

$(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>
