从 json 响应中获取值
我从服务器收到以下 JSON 响应：
{
"msg": "S",
"comments": {
"iRecords": [{
"id": "9",
"bid": "1",
"uid": "5",
"comment": "This is # 009",
"adate": "Tuesday, 5th April, 2011 11:15:05",
"status": "1",
"userid": "5",
"username": "pavlos",
"oauthprovider": "l",
"profile_link": null
}]
}
}
我使用以下 javascript/jQuery 来获取值，但它没有显示任何内容：
obj = jQuery.parseJSON(responseText);
alert(obj.comments.iRecords[adate]);
注意：alert(obj.msg); 工作正常。
如何在 Javascript 中获取 adate 的值。
提前致谢
I have following JSON response received from server:
{
"msg": "S",
"comments": {
"iRecords": [{
"id": "9",
"bid": "1",
"uid": "5",
"comment": "This is # 009",
"adate": "Tuesday, 5th April, 2011 11:15:05",
"status": "1",
"userid": "5",
"username": "pavlos",
"oauthprovider": "l",
"profile_link": null
}]
}
}
Iam using following javascript/jQuery to get values but it is showing nothing:
obj = jQuery.parseJSON(responseText);
alert(obj.comments.iRecords[adate]);
Note: alert(obj.msg); is working fine.
How can I get value of adate in Javascript.
Thanks in advance

您尚未定义名为
adate的变量，并且iRecords是一个数组。如果您使用方括号表示法，则必须传入包含属性名称的字符串，而不是变量与属性同名。
You haven't defined a variable called
adateandiRecordsis an arrayIf you use square bracket notation then you have to pass in a string containing the property name, not a variable with the same name as the property.
iRecords保存一个对象数组，因此您需要访问数组的第一个索引才能获取第一个对象：或
iRecordsholds an array of objects, so you need to access the first index of the array to get to the first object:or
obj 有一个注释对象，该对象有一个 iRecods 成员，它是一个包含 1 个元素的数组；
obj has a comments object which has an iRecods member which is an array with 1 element so;
