如何处理从AJAX调用返回的数组？

I am trying to handle an array coming back from an ajax call. My current situation is a button gets clicked, and when clicked, it fires an ajax call. Here is a snippet of the PHP after ajax has been called..

我正在尝试处理从ajax调用返回的数组。我目前的情况是点击了一个按钮，当点击它时，它会触发一个ajax调用。这是ajax被调用后的PHP片段..

function count_total() {
    $count = get_count();
    if ($count == 0) {
        $count = 1; 
    }
    $total = get_total();
    $response = array('count' => $count, 'total' => $total);
    echo $response;
    exit;
}

Ok so now this $response variable is passed back to the JS side and if I alert the variable obviously it will say "Array". So my question is, how can I work with this array? I am trying to get the key/value out?

好的，现在这个$ response变量被传递回JS端，如果我警告变量显然会说“Array”。所以我的问题是，我如何使用这个数组？我想要获得键/值？

Or I can't pass an array to it like that?

或者我不能像那样传递数组？

Any ideas?

有任何想法吗？

change your echo to be this.

改变你的回声是这样的。

echo json_encode($response);

and then instead of alerting the response, parse it with a json parser library like this.

然后代替提醒响应，用这样的json解析器库解析它。

Then you will have a true javascript object not an array because you're using a associative array.

那么你将拥有一个真正的javascript对象而不是一个数组，因为你正在使用一个关联数组。

PHP isn't sending back the array itself, just the word 'Array'. It can only send back plain text/HTML (or files if you mess with headers).

PHP不会发回数组本身，只是单词'Array'。它只能发回纯文本/ HTML（如果你搞乱标题，则发送文件）。

Look into either using JSON or an equivalent method that will take an array and put it into a text form to be recovered in JavaScript or roll your own.

查看使用JSON或等效方法，它将获取一个数组并将其放入文本形式，以便在JavaScript中恢复或滚动自己的数组。

For example you could echo "count=12;total=254" from PHP and use JavaScripts split() function to break it back into it's parts.

例如，您可以从PHP回显“count = 12; total = 254”，并使用JavaScripts split（）函数将其分解为其部分。
