layui type2 通过url给iframe子页面传值的例子

 layui.use(["layer"], function () {          layui.layer.open({            type: 2,            title: "管理角色拥有的部门",            btn: ["确定修改", "关闭"],            content: '@Url.Content("~/Role/UserRoleView?rid=")'+a[0].ID + '&uid=' + a[0].UID,//这里指向office            btn1: function (index, layero) {              //获取子页面数据              var body = layer.getChildFrame('body', index);              var addData = body.find("#listFalse li");              console.log(addData);              var delData = body.find("#listTrue li")              console.log(delData);              if (addData.length==0&&delData.length==0) {                layui.layer.closeAll();                layui.layer.msg("没有做任何修改！");                return false;              } else {                var url = '@Url.Content("~/Role/AddRemoveUsers2Role")';                if ($(addData).find("span").length != 0) {                  var data = getListData(addData);                  $.ajax({                    type: "post",                    url: url,                    data: { "rid": a[0].ID, "uids": data },                    success: function (rst) {                      layui.layer.closeAll();                      layui.layer.msg("添加用户成功，其用户名分别为：" + data.toString());                     }                  })                };                if ($(delData).find("span").length != 0) {                  var data = getListData(delData);                  $.ajax({                    type: "post",                    url: url,                    data: { "rid": a[0].ID, "uids": data ,"Add":"false"},                    success: function (rst) {                      layui.layer.closeAll();                      layui.layer.msg("删除用户成功，其用户名分别为：" + data.toString());                    }                  })                }              }            },            btn2: function () {              layui.layer.closeAll();            }           })        })

  //页面初始化   $(function () {    var oid = args().oid;//获取父页面oid  })  //获取index传参rid args为传递过来的所有参数，类型为OBJDECT，调用为args();    var args = function(params){      var a = {};      params = params || location.search;      if(!params) return {};      params = decodeURI(params);      params.replace(/(?:^/?|&)([^=&]+)(?:/=)([^=&]+)(?=&|$)/g,function(m,k,v){ a[k] = v; });      return a;    };
