ysian

问题描述

这里先说下流程
1.先创建表格
截图
2.一键菜单,生成了相关的前端代码,到分类模块点击新增,但是上级分类显示暂无数据
截图
3.然后参考权限管理中的菜单管理,添加部分代码

                // 刷新表格数据
                window.refreshTable = function(param) {
                    table.reloadData("data-table", {
                        scrollPos: "fixed"

                }
            })

        </script>
    </body>
</html>

之后树形单选下拉还是没有数据;这是ArticleClassify/select?format=tree&type=0,1接口中的数据
{"code":0,"data":[{"name":"PHP","value":"1","id":1,"pid":0,"children":[{"name":"pj","value":"2","id":2,"pid":1}]}],"msg":"ok"}

有这方面经验的前辈没,这是什么原因导致的;

1、创建表格
2、设置控件
3、然后然后一键生成菜单
就完事了，生成的菜单就是带控件的，不用后面手动添加代码。

还有弹窗的iframe页面不是index.html，是update.html，就算你改代码也改错地方了

    多谢啦,确实改错地方了.
