options:the load options,
// the parameters for options:
updateMode: currently we only support 'server'
updateUrl: set the server side url for update action based on json

const imagecopyurl = "/GridJs2/CopyImage";
const basiczorder = 5678;
xs.setImageInfo(imageurl, imageuploadurl1, imageuploadurl2, imagecopyurl, basiczorder);
- establecer información para la operación de descarga para la acción del lado del servidor
xs.setFileDownloadInfo(downloadActionUrl);
// the parameters are:
downloadActionUrl: the get download file action URL in the server side controller
for example:
