js的定位实现和ip查询

sina的api

var GetLocationFromSina = function (successFunc, errorFunc) {
    $.getScript('http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js', function(result) {
        if (remote_ip_info.ret == '1') {
            var province = remote_ip_info.province;

                province = province + "市";
            } else {
                province = province + "省";
            }
            var curCity = {
                id: '000000',
                name: province,
                date: curDateTime()
            };
            //当前定位城市
            $.cookie('VPIAO_PC_CURRENTCITY', JSON.stringify(curCity), { expires: 7, path: '/' });
            successFunc(province);
