Jquery如何操作json中的map对象的示例代码

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));  
        }  
    }  
}

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:@@##@@" + key  
                                + "</div>";  
                          // html += value;  
                          // html += key;

                }  
            }
