sina的api

baidu的api

页面调用
1 var localcurrent = function() { 2 var currcookie = $.cookie(‘VPIAO_PC_CURRENTCITY‘); 3 if (currcookie && currcookie != "") { 4 var currCity = JSON.parse(currcookie); 5 currentcity = currCity.name; 6 search(1); 7 } else { 8 GetLocationFromSina(function (p) { 9 var currcookie = $.cookie(‘VPIAO_PC_CURRENTCITY‘);10 if (currcookie && currcookie != "") {11 var currCity = JSON.parse(currcookie);12 currentcity = currCity.name;13 14 } else {15 currentcity = p;16 }17 search(1);18 }, function (error) {19 $.toptip(error);20 var defcookie = $.cookie(‘VPIAO_PC_DEFAULTCITY‘);21 if (defcookie && defcookie != "") {22 var defCity = JSON.parse(defcookie);23 currentcity = defCity.name;24 search(1);25 }26 });27 }28 };
ip查询
1 var GetClientIp = function () {2 var ip;3 var url = ‘http://chaxun.1616.net/s.php?type=ip&output=json&callback=?&_=‘ + Math.random();4 $.getJSON(url, function (data) {5 ip = data.Ip;6 });7 return ip;8 }
