Extjs 将SDK2网格导出为CSV

我想将我的SDK2网格导出到CSV或Excel-我怀疑Rally某处可能存在此代码，因为您可以将例如用户故事从公文包项目导出到CSV

是否有一个解决方案，人们知道，并可以张贴

我在Sencha网站上找到了一些a，它完全是客户端，但我无法使用Rally SDK2网格使其工作

---

如果您只想转到CSV，我想可能会有更简单的解决方案。

您可以通过从底层存储获取数据并创建一个网格来创建一个导出。您可能会遇到一些问题，无法在不同的浏览器中正常工作

---

您还可以查看此处制作的内容。

查看了上面Charles给出的示例，并制作了这个简化对象以导出EXT-JS网格，因此也可以使用Rally网格

对于IE，直接转到Excel，对于其他浏览器，下载CSV-但是使用数据URI方法有点困难文件名是不可控的，Excel在打开之前会抱怨一点，但是它的功能是有效的

如果有人真的知道Javascript，想发布一个改进，我将不胜感激

美好的如果typeofielddata==number{text=+fieldData；}否则如果！fieldData.match{//不是我们识别的字符串或对象…请将其清空text=；}否则{text=fieldData；}很好。如果typeofielddata==number{text=+fieldData；}否则如果！fieldData.match{//不是我们识别的字符串或对象…请将其清空text=；}否则{text=fieldData；}
