Мне нужно передать значение объекта php json в javascript. Вот как я это делаю;
<script type="text/javascript"> var msg_top = <?php echo searchResults('windows');?>; </script> Это функция php SearchResults, которая возвращает json:
function searchResults($q) { $host = "http://search.twitter.com/search.atom?q=" . urlencode( $q ) . "&rpp=100"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $host); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); //Raw xml $result = curl_exec($ch); curl_close($ch); $xml = simplexml_load_string($result); return json_encode($xml); }
Ошибка в консоли ошибок отсутствует, но нет принятого значения. Он выводится как array (0) {} для var_dump ($ _ POST); EDIT Я добавил тестовое предупреждение после успешной функции и распечатывает сбой
Это сценарий
<head> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"> </script> </head> <body> <script type="text/javascript"> var msg_top = <?php echo searchResults('windows');?>; </script> <script type="text/javascript"> $(document).ready(function() { $.ajax({ url: "script.php", type: "POST", dataType: "json", data: "msg_top", success: function(msg){ alert("success"); } }); alert("failure"); }); </script> </body> </html>
это json из twitter
