Question

我正在利用地名网络服务在我的网站上进行登记。如果出现错误,我就希望发出一份带有错误的电子邮件。 www.geonames.org 但我不敢肯定如何展示。

在用户进入时,使用吉克里的地名进行汽车结业地点。

$( "#location" ).autocomplete({
            source: function( request, response ) {
                $.ajax({
                    url: "http://ws.geonames.org/searchJSON",
                    dataType: "jsonp",
                    data: {
                        q: request.term,
                        featureClass: "P",
                        style: "full",
                        maxRows: 10 
                    },
                    success: function( data ) {
                        response( $.map( data.geonames, function( item ) {                                                           
                            return {
                                label: item.name + (item.adminName1 ? ", " + item.adminName1 : "") + ", " + item.countryName,
                                value: item.name,
                                latitude: item.lat,
                                longitude: item.lng,
                                status: item.status
                            }
                        }));

In the success function the last parameter status should return the status of the request. I appended that to a div but nothing appears. Please help me.. I m not sure what I m doing wrong.

I played around quite a bit with this one and I think you re overthinking it. It looks to me like the only situation in which your JSON response is going to contain a status attribute is when the HTTP response is not 200.

例如,当你从服务器获得503台服务超负荷时,这一成功功能实际上从未运行。从我能告诉大家的角度来看,需要添加<代码>error:功能(数据){......},以便能够查阅<代码>status<>/code>。希望是有益的!
