Jquery如何操作json中的map对象的示例代码

后台java代码，生成Map数据

if (Collections.isNotEmpty(vidList)) { 
 
 this.dtcMap = new HashMap<String, Object>(); 
 
 for (String vid : vidList) { 
 
 boolean isExist = (iCache.get("EMC" + vid) != null); 
 
 // LOGGER.info("******************************** vid = " + iCache.get("EMC" + vid)); 
 if (isExist) { 
 
 dtcMap.put(vid, iCache.get("EMC" + vid)); 
 } 
 } 
}

前台Jquery操作

function getDtcAndGps() { 
 
 $.Ajax( { 
 url : $.webPath + 'obd/monitor/getMonitorRtDtc.do', 
 success : function(data) { 
 
 if (data.errMsg) { 
 
 $.alert(data.errMsg); 
 } else { 
 
 $("#carContentDiv").empty(); 
 var html = ""; 
 $.each(data.dtcMap, function(key, value) { 
 
 html += "<div id='" + key + "' class='carImg'>A:<img src='" + $.webPath 
 + "resources/images/demo/car1.jpg' class='carIcon'/>" + key 
 + "</div>"; 
 // html += value; 
 // html += key; 
 }); 
 
 $(html).appendTo("#carContentDiv"); 
 // $.alert(data.dtcMap); 
 } 
 } 
 }); 
}
