问题描述

我正在寻找一个 Javascript 函数，它将我的数据网格 (zero.grid.DataGrid) 中的数据导出到一个 CSV 文件或可以由电子表格应用程序打开的类似文件中.

I am looking to get a Javascript function which will export my datagrid (zero.grid.DataGrid) full of data into a CSV file or something similar which can be opened by a spreadsheet application.

Is there any standard way of doing this out there..

推荐答案

我很难将 Exporter 插件与 EnhancedGrid 一起使用，并使用 servlet 作为后端.最后我使用 iFrame 使它工作:

I had tough time with using Exporter plugin with EnhancedGrid using servlet as backend. Finally I made it work by using iFrame:

我写了一篇博文，这样我就不必再搜索了.

I have written a blog post so that I don't have to search again.
