jQuery中使用each处理json数据

var obj = { id01:'true', id02:'flase', id03:'true'};$.each(obj,function(key,val){    if(val == 'true'){       $('#' + key).addClass('focus');     } });

[ {"Id": 10004, "PageName": "club"}, {"Id": 10040, "PageName": "qaz"}, {"Id": 10059, "PageName": "beauty"}]

$.each(data, function(i, item) {  alert(item.PageName);});
