来到新的项目组快两个月的时间了，今天开需求分析电话会议时；业务提出来根据拼音进行城市姓名索引的需求。所以自己编写了一个方法进行从后台得到的json数据进行一个按照城市首写字母的城市索引!代码如下：

$rootScope.getLastCityList = function(list){
          var scope = this;
          if(list){
             var TheTempCityList = new Array();
             for(var i=0;i<list.length;i++){
                for(var j=0;j<list[i].cityModelList.length;j++){
                   TheTempCityList.push(list[i].cityModelList[j]);
                }
             }
             //过滤出所有的城市列表 var AObjectList=[];
             var BObjectList=[];
             var CObjectList=[];
             var DObjectList=[];
             var EObjectList=[];
             var FObjectList=[];
