JSON字符串操作移除空串更改key/value的介绍

//删除JSON对象value值
var json=[.....];
delete(json['key']);
或者
delete(json.key);
//添加对象object
json.object=value;
或者
json['object']=value;

 function removeEmptyObject(object){
   for (var i in object) {
  var value = object[i];
  if (typeof value === 'object') {

     continue;

   //按需添加

  } else {
