jQueryにgetJSONの使い方

参考コード:
$(document).ready(function(e) {
$.getJSON(“http://devcenter.xxx.net/json.aspx?n=6&jsoncallback=?”,function(result){
$(“.checkdevLst”).empty();
$.each(result, function(i,field){
var html=””;
html=”<li><a href=\””+field[“link”]+”\” target=\”_blank\”>”+field[“title”]+”</a></li>”;
$(“.checkdevLst”).append(html);
});
});
});
