<script>
(function() {
var flickerAPI = "http://apip.com/results.php?jsoncallback=?";
$.getJSON( flickerAPI,
(function( data ) {
$.each( data.items, function( index, value ) {
$('<li>' + value.a_name + '</li>').appendTo('#groups');
});
});
})();
</script>
As you can see from this fiddle , it is working fine. 从这个小提琴中可以看到,它运行良好。 What I do suspect is going wrong is that you're using http://apip.com/results.php
and you might be fooling jQuery into thinking you're doing a cross-domain request (which you might be doing), which is generally prohibited by browsers unless you use JSONP
. 我怀疑是错的是您使用的是http://apip.com/results.php
并且您可能在欺骗jQuery认为您正在执行跨域请求(您可能正在这样做),除非您使用JSONP
否则通常被浏览器禁止。 If you own http://apip.com/ , use 如果您拥有http://apip.com/ ,请使用
$.getJSON("/results.php", function (data) {
$.each(data, function (index, value) {
$('<li>' + value.a_name + '</li>').appendTo('#groups');
});
});
