把城市按首字母分类

函数

function group_pinyin(list,group_flag){
var array=[];
$.each(list,function(){
var store=[];
var group = this.FIRST_LETTER;//首字母
var item = this;
var array_index=-1;
var id = this[group_flag];
$.each(array,function(i){
if(this[group]){
store = this[group];
array_index = i;
return false;
}
})
var add = true;
$.each(store,function(){
if(this[group_flag]==id){
add=false;
}
})
if(add)store.push(item);
var obj = {sort:group};
obj[group]=store;
if(array_index!=-1){
array[array_index]=obj;
}else{
array.push(obj);
}
})
return array;
}
