我尝试从JSon服务检索数据,但我有一些问题,我无法通过调试过程。
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我用这个工具http://jsonformatter.curiousconcept.com/验证结果,它看起来很好。
[
{
"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"
}
]
}
]
但在另一种方式,当我使用。getjson方法从jquery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>
弹出式警报从未触发,据我所知,getJSON在检索我的JSON数据时出现一些错误后无声地失败。
我试着用firebug调试,我刚刚在控制台找到了这个关于头的
(对不起,我可以添加图像,我是新来的)

同样的演示页面从flickr触发JSON api,它没有任何抱怨,所以看起来我遗漏了什么。也许这是显而易见的。
如果有人能给我点提示,我会很感激的。
看起来像是一个跨站点脚本问题-您试图从外部站点的本地主机获取数据。一种解决方法是使用PHP作为"代理"。参见:http://jquery-howto.blogspot.com/2009/04/cross-domain-ajax-querying-with-jquery.html
