ajax小知识

1.ajax发送get请求时，需要注意如下情况：

var uri="http://127.0.0.1:8071/springmvcdemo/bigdataapi/publishdata";

1）若URL不加“？”，则变成proxy+"http://127.0.0.1:8071/springmvcdemo/bigdataapi/publishdata"+"&udbPath=...&mapName=....."；即将uri当作一个参数

2）加上“？”，则将url看做一个完整的路径

也可以在拼接地址时直接加上参数，如url = proxy + "http://127.0.0.1:8010/style.set?layer=" + layerName + "&backColor=" + backColor + "&item=" + itemVal;

var proxy="/webframe/biz/httpproxy/httpproxy.jsp?url=";
var url=proxy+"http://127.0.0.1:8071/springmvcdemo/bigdataapi/publishdata?";
            $.ajax({
                url:url,
                type:"GET",
                data:{udbPath:udbPath,
                    mapName:mapName,
                    hdfsPath:hdfsPath
                },
                dataType:"text",
                success:function(data){
                    //$(".stateInfo").html("");
                    //statecontainer="<span >发布完成，本次发布总共耗时60秒。</span>";
                    //$("#publishResultInfo").append(statecontainer);
                },
                error:function(x,e){
                    layer.alert("err");
                }
            })
