$.getJSON 在检索数据时出现无提示错误
我尝试从 JSon 服务检索数据,但遇到一些问题,无法通过调试过程。
我从这个动态服务中检索数据: http://www.synergiescanada .org/json/otherpublicationbyid?synid=synergies:bcn.arbutus.215.3263 我使用此工具验证结果 http ://jsonformatter.curiousconcept.com/ 看起来不错。

{
"name":"Dr. Andre Smith",
"publications":[
{
"id":"synergies:bcn.arbutus.215.3264",
"title":"Exploring death and dying through discourse",
"uri":"http:\/\/journals.uvic.ca\/index.php\/arbutus\/article\/view\/3264",
"date":"2010-10-18"
}
]
}
]
但以另一种方式,当我使用 jquery 中的 .getJSON 方法时,它会失败。
<script type="text/javascript">
$(document).ready(function() {
$.getJSON("http://www.synergiescanada.org/json/otherpublicationbyid?synid=synergies:bcn.arbutus.215.3263" ,
function(json) {
alert(json);
});
</script>
弹出警报永远不会被触发,据我所知,当 getJSON 检索我的 JSON 数据时出现一些错误后,它会默默地失败。
我尝试使用 firebug 进行调试 我刚刚在控制台中找到了关于标题的信息
(抱歉,我可以添加我是新的图像)

相同的演示页面触发来自 flickr 的 JSON api 并且它根本不抱怨,所以它看起来像我想念的这里有东西。也许这是显而易见的。
如果有人能给我一个线索,我将不胜感激。
I try to retrieve data from a JSon services but I have some problem and I'm not able to pass trough the debug process.
I retrieve data from this dynamique services : http://www.synergiescanada.org/json/otherpublicationbyid?synid=synergies:bcn.arbutus.215.3263 I validate the result with this tool http://jsonformatter.curiousconcept.com/ and it look fine.

But in another way when I use .getJSON method from jquery the it fail.
<script type="text/javascript">
$(document).ready(function() {
$.getJSON("http://www.synergiescanada.org/json/otherpublicationbyid?synid=synergies:bcn.arbutus.215.3263" ,
function(json) {
alert(json);
});
</script>
The popup alert is never trigged and as I understand getJSON fail silently after having some king of error when he retrive my JSON data.
I try do debug with firebug I just found this into the Console about the headers
(sorry I can add image I'm new)

The same demo page trigger JSON api from flickr and it doesn't complain at all so it look as I miss something here. Maybe it's obvious.
If someone can give me a clue I'll appreciate.

看起来像是跨站点脚本问题 - 您试图从外部站点的本地主机获取数据。解决方法可能是使用 PHP 作为“代理”。请参阅: http://jquery-howto .blogspot.com/2009/04/cross-domain-ajax-querying-with-jquery.html
Looks like a cross-site scripting issue -- your trying to get data from localhost of an external site. A workaround could be to use PHP as a "proxy." See: http://jquery-howto.blogspot.com/2009/04/cross-domain-ajax-querying-with-jquery.html
