Jquery请求Ajax的json数据

 

获得单个json对象

$.getJSON("test.js", { name: "John", time: "2pm" }, function(json){
  alert("JSON Data: " + json.users[3].name);
});

获得json数组，处理

$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?", function(data){
  $.each(data.items, function(i,item){
    $("<img/>").attr("src", item.media.m).appendTo("#images");
    if ( i == 3 ) return false;
  });
});
