Your data needs to be encoded in a format that JavaScript can understand, like JSON. You want to serialize the PHP array and return that as the HTTP Response, more information on how to JSON serialize data can be found here. Once the data is serialized, you can parse it in the ResponseText as though it were a JavaScript object (i.e. you can pull data like this: ResponseText[0].some_key)
您的数据需要以JavaScript可以理解的格式进行编码，例如JSON。您希望序列化PHP数组并将其作为HTTP响应返回，有关如何JSON序列化数据的更多信息可以在此处找到。一旦数据被序列化，你可以在ResponseText中解析它，好像它是一个JavaScript对象（即你可以拉这样的数据：ResponseText [0] .some_key）
I should note that jQuery makes this very, VERY easy. Like... this easy:
我应该注意到jQuery非常简单。喜欢......这很容易：
var url = '/json-data.php?id=2';
$.getJSON(url, function(data) {
$("#target").text(data.some_key);
}
