function updateUser(data) {
    layer.open({
    type : 2,
    title : '修改用户信息',
    skin : 'layui-layer-rim', //加上边框
    closeBtn :1,
    area : [ '400px', '600px' ] //宽高
                  ,
    id : 'LAY_layuipro' //设定一个id，防止重复弹出
                  ,
    offset : '10px',
    moveType : 0 //拖拽模式，0或者1
                  ,
    content : 'lz/user/user_upd.html',
                  
    success : function(layero, index2) {

    var body = layer.getChildFrame('body', index2);
    //获取content的窗口
    var iframeWin = layero.find('iframe')[0].contentWindow;
    body.find("#id").val(data.id);
    body.find("#username").val(data.username);
