【jQuery 技术一】跨域访问返回JSON数据

此方法好像仅限返回json数据

 

var s = document.createElement("SCRIPT");
    s.src=""+new Date().getTime();
    s.type = "text/javascript";
    s.language = "javascript";
    document.getElementsByTagName("HEAD")[0].appendChild(s);
    if(document.all){
        s.onreadystatechange = function(){//IE用
            var state = s.readyState;
            if (state == "loaded") {
                City = returnCitySN.cname.split("-")[1];
                Province = returnCitySN.cname.split("-")[0];
                DataResetByIp();
                }
            };
    } else {
            s.onload = function() {//FF用

                City = returnCitySN.cname.split("-")[1];
                Province = returnCitySN.cname.split("-")[0];
                DataResetByIp();
            };
    }

 内容格式要求

var returnCitySN = {cip:"10.1.1.1",cid:110000,cname:"北京-北京"}
