自用ajax的json请求

function singlePriceSubmit(){

    var json={};

    json["area"]=areaStr1;

    json["goodCateIdStr"]=goodCateIdStr;

    var arr=[];

    $("#singlePriceId table tbody tr").each(function(){

        var cells=this.cells;

        var json1={};

        json1["goodsId"]=cells[0].childNodes[0].id;

        json1["price"]=$.trim(cells[1].childNodes[0].value);

        json1["maxPayIntegrateRate"]=$.trim(cells[2].childNodes[0].value);

        json1["receivableIntegrateRate"]=$.trim(cells[3].childNodes[0].value);

        arr.push(json1);

    });

    if(!checkData(arr)){

        return;

    }

    json["arr"]=arr;

    CommonUtil.showOverlay();

    var ajax = new $ax(Feng.ctxPath + "/goodPrice/singlesetprice", function (data) {

        CommonUtil.hideOverlay();

        Feng.info("操作成功!");

        $("#singlePriceId").modal("hide");

    }, function (data) {

        CommonUtil.hideOverlay();

        Feng.error("操作失败!" + data.responseJSON.message + "!");

    });

    ajax.set("json",JSON.stringify(json));

    ajax.start();

}
