从php到JavaScript的数组
我试图用json将数组列表从php转移到javascript，但它不起作用。
JS：
$.ajax({ url: 'getProfilePhotos.php', type: 'post', // post or get method data: {}, // if you need to pass post/get parameterds you can encode them here in JSON format dataType: 'json', // the data type you want returned... we will use json success: function(responseData) { var arrayList[0] = new Array(); var lung = arrayList.length; for(var i = 0; i<lung; i++) //arrayList[i] = responseData.i; console.log(responseData.i); }}); PHP：
<?php $array = array(); $nr = count($friends['data']); for($i = 0; $i array("http://graph.facebook.com/".$friends['data'][$i]['id']."/picture"); ?> <img src="http://graph.facebook.com//picture" />
Christopher McCann的更新
我在控制台中出错了。 这是错误。
[02：46：21.281]缺少财产清单@ http://romanager.ro/api/examples/script.js:3
script.js中的第3行是
type: 'post', // post or get method
事实上我想从facebook个人资料照片中获取。 用PHP脚本我设法得到照片，但我可以将id从php转移到javascript。 如果你需要我将尝试编写整个PHP脚本和JavaScript文件。
更新
仍然有这些脚本的问题。 在PHP脚本我做和Facebook上的用户身份validation，因为我需要来自Facebook的用户ID来获取他的朋友的ids。 登录我需要在PHP脚本中创建html。 好吧，我将发布我的脚本代码，我希望你能帮助我。
PHP脚本：
'137061043024243', 'secret' => '619c4dc94343584eb7792ae9933978c9', 'cookie' => true, )); // We may or may not have this data based on a $_GET or $_COOKIE based session. // // If we get a session here, it means we found a correctly signed session using // the Application Secret only Facebook and the Application know. We dont know // if it is still valid until we make an API call using the session. A session // can become invalid if it has already expired (should not be getting the // session back in this case) or if the user logged out of Facebook. $session = $facebook->getSession(); $me = null; // Session based API call. if ($session) { try { $uid = $facebook->getUser(); $me = $facebook->api('/me'); $friends = $facebook->api('/me/friends'); } catch (FacebookApiException $e) { error_log($e); } } // login or logout url will be needed depending on current user state. if ($me) { $logoutUrl = $facebook->getLogoutUrl(); } else { $loginUrl = $facebook->getLoginUrl(); } // This call will always work since we are fetching public data. $naitik = $facebook->api('/naitik'); ?> php-sdk body { font-family: 'Lucida Grande', Verdana, Arial, sans-serif; } h1 a { text-decoration: none; color: #3b5998; } h1 a:hover { text-decoration: underline; } window.fbAsyncInit = function() { FB.init({ appId : 'getAppId(); ?>', session : , // don't refetch the session when PHP already has it status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true // parse XFBML }); // whenever the user logs in, we refresh the page FB.Event.subscribe('auth.login', function() { window.location.reload(); }); }; (function() { var e = document.createElement('script'); e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; e.async = true; document.getElementById('fb-root').appendChild(e); }()); <a href="https://stackoverflow.com/questions/4823516/array-from-php-to-javascript/">

您的PHP部分是错误的，因为您仍在尝试生成HTML，而不仅仅是JSON 。
循环中的数组处理也是不正确的。
尝试将PHP代码更改为：
在这种情况下，标头将不起作用，因为在调用header（）之前无法向浏览器输出任何内容（包括空格）。 在for循环中，您将HTML输出到浏览器，这将导致错误。
正如Orbling所说，你也没有正确地将元素添加到数组中。 我只是假设这是你想要的，但你想要的循环是：
for($i = 0; $i < $nr; $i++) { $array[] = "http://graph.facebook.com/".$friends['data'][$i]['id']."/picture"; }
我对你想用javascript实现的目标感到困惑。 我将使用以下代码来简化：
$.post("getProfilePhotos.php", function(data) { alert(data); //DO WHAT YOU WANT WITH DATA HERE }, "json");
我会首先运行该代码以检查您是否返回JSON，然后使用回调函数来执行返回的json所需的操作。
