我在一个服务器上发送一些请求,它回复我：
{"COLUMNS":["REGISTRATION_DT","USERNAME","PASSWORD","FNAME","LNAME","EMAIL","MOBILE","FACEBOOK_ID"],"DATA":[["March,17 2012 16:18:00","someuser",somepass,"somename","somesur","someemail",sometel,"someid"]]}
我尝试了很多,但似乎没有为我工作！
var xml2 = this.responseData;
var xml3 = xml2.getElementsByTagName("data");
Ti.API.log(xml3.FNAME);
对于这个代码,我得到“null”.
任何帮助将不胜感激！
解决方法
如果你想使用JSON格式,你的问题是[…]中的数据也需要成对,并分组在{…}像
here.
例如,
{
"sales": [
{ "firstname" : "John","lastname" : "Brown" },{ "firstname" : "Marc","lastname" : "Johnson" }
] // end of sales array
}
所以你可能有：
{"COLUMNS": [
{"REGISTRATION_DT" : "19901212","USERNAME" : "kudos","PASSWORD" : "tx91!#1",... },{"REGISTRATION_DT" : "19940709","USERNAME" : "jenny","PASSWORD" : "fxuf#2",{"REGISTRATION_DT" : "20070110","USERNAME" : "benji12","PASSWORD" : "rabbit19",... }
]
}
如果服务器正在向您发送一些您称为res的内容,那么您可以在Javascript中解析它：
var o=JSON.parse(res);
然后,您可以在列中循环遍历每个实例,如下所示：
for (var i=0;i<o.COLUMNS.length;i++)
{
var date = o.COLUMNS[i].REGISTRATION_DT; ....
}
