我有以下javaScript对象:
var theData = {
"data": [
{
"name": "Event1",
"start_time": "2015-01-15T22:00:00-0200",
"end_time": "2015-01-16T07:00:00-0200",
"timezone": "America/Sao_Paulo",
"location": "Somewhere",
"id": "824583590897935"
},
{
"name": "Event2",
"start_time": "2015-01-14T22:00:00-0200",
"timezone": "America/Sao_Paulo",
"location": "Somewhere",
"id": "1522505051359796"
}
],
"paging": {
"cursors": {
"after": "MzA0MjY5OTI5NzgwODIz",
"before": "ODI0NTgzNTkwODk3OTM1"
},
"next": "https://graph.facebook.com/v2.2/217733628398158/events?access_token=CAACEdEose0cBAAW4SjUBnZB9x1Y6euJS6Bbmky2ZBfyMJ7eq4hPyy0g6lrk9itZCS2Rf2vmAmlYS6qcwIBLVs8Vm5ZBnDYbW7ldni3LdmwAqrZAjVXQrloT0nunu6brW21tBzRXyZAyLR7L2oaF14cmusoXzndsadsakvsZyAYSkjQ52g57BW3VqbAHEMQnTtq5uYb4NOHN5xa1IvdecZCgSHNHzKPWYq1VsWZB7qvQgHXvoRAZD&limit=25&after=MzA0MjY5OTI5NzgwODIz"
}
}
所以我想迭代这个对象。 我有以下代码正在运行。但我是Javascrip的新手,这样我正在做的是一种高度复杂的方式。一旦这种情况被召唤了很多次,我怎能做到这么简单呢?
for (var key in theData) {
var obj = theData[key];
for (var prop in obj) {
var eventObj = obj[prop];
for (var attribute in eventObj){
if(eventObj.hasOwnProperty(attribute)){
console.log(attribute + " = " + eventObj[attribute]);
}
}
}
}

您可以使用Object.keys
:
Object.keys(httpResponse).forEach(function (key) {
console.log(key + ' = ' + httpResponse.data[key]);
});
它更容易实现,也更易读。
对于您的代码,您可以使用以下内容:
function scan(obj, root) {
root = root || '';
Object.keys(obj).forEach(function (key) {
if (typeof(obj[key]) === 'object') {
scan(obj[key], root + key + '.');
}
else {
console.log(root + key + ' = ' + obj[key]);
}
});
}
scan(httpResponse);
您可以a fiddle显示上述示例。
如果您需要支持IE< 9,您可能需要使用a polyfill。
