转化json key的命名的一个小东西。js代码，，c_name_id <==> cNameId

function changeName(json,type){
    var out={};
    if(type == 1){
        for( var key in json){
            var arr=[];
            arr = key.split(‘_‘);
            for (var i=1;i<arr.length;i++){
                var prev = arr[i].substring(0,1).toUpperCase();
                var next = arr[i].substring(1);
                arr[i] = prev+next;
            }
            var newkey =  arr.join(‘‘);
            out[newkey] = json[key];
        }
    }else{
       for(var key in json){
            var len = key.length;
            var val = json[key];
            for(var i=1;i<len;i++){
                var tmp = key.charAt(i);
                if(tmp<=‘Z‘ && tmp>=‘A‘){
                    key = key.split(tmp).join(‘_‘+tmp.toLowerCase());
                    len = key.length;
                }
            }
            out[key] = val;
       }         
    }
    console.log(out);
    return out;
}
