我有一个json文件存储在静态网址中,我想抓取它并提取我们的数据对象.
I have a json file being stored in a static url, i would like to grab it and pull our the data objects.
<div id="content"></div> <script src="ajax.googleapis/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function(){ $.getJSON('s3.amazonaws/wallyball_production/comedy.json', function(data){ $("#content").html(data); }); }); </script>这什么都不输出?我做得很快,不确定为什么我什么都没看见吗?
This isn't outputting anything? I did it very quickly, not sure why I'm not seeing anything?
推荐答案跨域AJAX调用需要jsonp(或编写代理服务器端脚本).只要正确设置了远程服务器(我认为亚马逊会做到),使用jQuery就很容易:
Cross-domain AJAX calls require jsonp (or writing a proxy server-side script). As long as the remote-server is setup properly (I'd think Amazon would be) it's pretty easy with jQuery:
$.ajax({ url : 's3.amazonaws/wallyball_production/comedy.json', dataType : 'jsonp', success : function (data) { //$('#content').html(data); for (var i = 0, len = data.length; i < len; i++) { //`data[i].something` will access the `something` property an index of the JSON returned } } });请注意,您将获得JSON作为响应,因此您需要遍历它,然后再将其附加到DOM.
Note that you will get JSON in response so you will need to iterate through it before appending it to the DOM.
以下是jQuery $.ajax()的文档: api.jquery/jquery.ajax
