如何使用单个对象的for循环遍历Restfulwebserivice。并且我不想在每个循环中使用，所以我该怎么做。我无法使用

获取数据

  for(var key in data) {
                    alert(data[key].hotel_geo_node.name);

您无法使用＆＃34;标准＆＃34;循环访问对象的键。 for循环，因为它不是数组，它的键不是数字。你只能使用for-in循环循环抛出它：

for(var key in data) {
    if(data.hasOwnProperty(key)){ // check if 'key' property is in object 'data' and not in it's prototype chain
        doTheStuff(data[key]);
    }
}
