利用jQuery解析獲取JSON數(shù)據(jù)

$(function(){

   //使用getJSON方法取得JSON數(shù)據(jù)
  $.getJSON(　　
  url,
  //處理數(shù)據(jù) data指向的是返回來的JSON數(shù)據(jù)
  function(data){
    //生成標(biāo)題和標(biāo)題連接
    var tit="<a href='"+ data.link +"'>"+data.title +"<\/a>";
    $("h2").html(tit); 　　
    //出現(xiàn)在指定位置H1 內(nèi)
    $("#ginfo").find("p").eq(0).html(data.modified);
    $("#ginfo").find("p").eq(1).html(data.generator);
    var lis=""; 　
    //li 列表項(xiàng)目
    $(data.items).each(function(i,ite){ 　
     //遍歷JSON數(shù)據(jù)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); 
    //將遍歷出來的數(shù)據(jù)呈現(xiàn)在所需位置
    $("li").hover(function(){$(this).addClass("hov")}, function(){$(this).removeClass("hov")});
