json array in jquery return data undefined
I'm trying to pull data to continously refresh some news from a source
data.php
$fecha = $_GET['fecha'];
$feed = array();
$result = mysql_query("SELECT * FROM envivo WHERE fecha >= '".$fecha."' ORDER BY fecha DESC");
$existe = mysql_num_rows($result);
if ($existe != 0) {
while ($data = mysql_fetch_array($result)) {
$jsondata = array();
$jsondata['titulo'] = $data['titulo'];
$jsondata['link'] = $data['link'];
$jsondata['fuente'] = $data['fuente'];
$feed[] = $jsondata;
}
echo json_encode($feed);
}
live.php

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript">
function restults(data) {
$(data).each(function() {
$("#envivo").append("<li>Titulo: " + data.titulo + " Link: " + data.link + " Fuente: " + data.fuente + "</li>");
});
}
$(document).ready(function(){
var fecha = Math.round((new Date()).getTime() / 1000);
setInterval(function() {
$.ajax({
data: "fecha="+fecha,
type: "GET",
dataType: "json",
url: "data.php",
success: function(data){
restults(data);
}
});
}, 5000);
});
</script>
</head>
<body>
<div id="envivo">
</div>
</body>
</html>
When running index.php, data.php it's called via ajax, and it returns something like this
[{"titulo":"Test 1302开发者_高级运维662957","link":"http:\/\/www.google.com","fuente":"Zuker"},{"titulo":"Test 1302662957","link":"http:\/\/www.google.com","fuente":"Zuker"},{"titulo":"Test 1302662631","link":"http:\/\/www.google.com","fuente":"Zuker"}]
Everything fine at this point... now i'll try to retrieve and append that data
on firebug console
[{"titulo":"Test 1302662957","link":"http:\/\/www.google.com","fuente":"Zuker"},{"titulo":"Test 1302662957","link":"http:\/\/www.google.com","fuente":"Zuker"},{"titulo":"Test 1302662631","link":"http:\/\/www.google.com","fuente":"Zuker"}]
So it's fine... but when using
$(data).each(function() {
$("#envivo").append("<li>Titulo: " + data.titulo + " Link: " + data.link + " Fuente: " + data.fuente + "</li>");
});
i'm getting undefined for each value... any ideas?
thanks in advance
$.fn.each() is designed to iterate over dom elements. You want $.each(), which iterates over any generic collection, like an array of objects, for example. Change your .each() code to something like this:
$.each(data, function(index, data) {
$("#envivo").append("<li>Titulo: " + data.titulo + " Link: " + data.link + " Fuente: " + data.fuente + "</li>");
});
加载中,请稍侯......
