我一直在找一个星期而且我找不到这种情况的答案。
我通过jsonp请求数据。
$.ajax({
type:'GET',
dataType: "jsonp",
url: "http://www.domain.com/app/loadFeedsApp.php",
sync: true,
contentType: "application/json",
dataType: 'jsonp',
success: function(data) {
console.log(data);
}
});
在我的服务器端,我发送了这样的信息:
$jarr = array();
$af = 0;
while( $row = mysql_fetch_array($result) )
{
$html = array("Appfeed".$af."" => array(
"cnty" => stripcslashes($row['cnty']),
"feed" => stripslashes($row['feed']),
"feedId" => stripslashes($row['feedId']),
"nickname" => stripslashes($row['nickname']),
"state" => str_replace("\r\n",'', $row['state']),
"date" => date("d/m/y", strtotime($row['date'])))
);
array_push($jarr, $html);
$af++;
}
echo $_GET['callback'] . '(' . json_encode($jarr) . ');';
它返回数据:
jQuery21007744578921701759_1395250905357({
"Appfeed0":
{
"cnty":"MEXICO",
"feed":"text",
"feedId":"201",
"nickname":"chaparra",
"state":"Tamaulipas",
"date":"27\/02\/14"
}
});
jQuery21007744578921701759_1395250905357({
"Appfeed1":
{
" cnty ":"MEXICO",
"feed":"text ",
"feedsId":"198",
"nickname":"estudiante",
" state ":"Tamaulipas",
"date":"26\/02\/14"
}
});
jQuery21007744578921701759_1395250905357({
"Appfeed2":
{
" cnty ":"MEXICO",
"feed":"text ",
"feedsId":"197",
"nickname":"el roger",
" state ":"Tamaulipas",
"date":"26\/02\/14"
}
});
但是当我尝试在java脚本中循环显示它时,它只显示最后一个Feed(Appfeed2)。当我在console.log()中打印数据时。它看起来就像刚收到最后一个饲料。
Object {Appfeed2: Object}
1. Appfeed2: Object
1. state: "Tamaulipas"
2. date: "26/02/14"
3. feed: "Ayer fui a sacar mi licencia, sin saber manejar, no hice fila y solo me costo 200 pesos mas. Creo que sere taxista "
4. feedId: "197"
5. nickname: "el roger"
6. cnty: "MEXICO"
7. __proto__: Object
2. __proto__: Object
有什么想法吗?我正在考虑jsonp返回数据的方式,所以我尝试使用方括号,使用和没有get回调,但它失败了。
非常感谢你的帮助!

你需要确保在你的PHP代码中,你只是在循环结束后回显出JSON(P)一次。您需要构建所需的数组,然后在最后回显它。
$jarr = array();
$af = 0;
while( $row = mysql_fetch_array($result) )
{
$jarr["Appfeed".$af] = array(
"cnty" => stripcslashes($row['cnty']),
"feed" => stripslashes($row['feed']),
"feedId" => stripslashes($row['feedId']),
"nickname" => stripslashes($row['nickname']),
"state" => str_replace("\r\n",'', $row['state']),
"date" => date("d/m/y", strtotime($row['date'])))
);
$af++;
}
echo $_GET['callback'] . '(' . json_encode($jarr) . ');';
P.S。你的AJAX调用有太多选择:
$.ajax({
type:'GET',
dataType: "jsonp",
url: "http://www.domain.com/app/loadFeedsApp.php",
success: function(data) {
$.each(data, function(i, v){
console.log(i);
console.log(v);
});
}
});
