http://query.yahooapis.com /v1/public/yql

var queryUrl = "\"http://www.kuaidi100.com/query?type=" + $("#type").val() + "&postid=" + $("#postid").val() + "\""; $.ajax({ url: 'http://query.yahooapis.com/v1/public/yql', //jsonp代理api dataType: "jsonp", data: { q: "select * from json where url=" + queryUrl, format: "json" }, success: function(result) { var res = result.query.results.json; console.log(res); } }, }) });
