我正在寻找一个 Javascript 函数，它将我的数据网格 (zero.grid.DataGrid) 完整的数据导出到 CSV 文件或可以由电子表格应用程序打开的类似文件中。
有没有标准的方法可以做到这一点..

这就是您将如何使用 PHP 服务器端脚本来实现的。
grid.exportGrid("csv",{
writerArgs: {
separator: ","
}
}, function(str){
var form = document.createElement('form');
dojo.attr(form, 'method', 'POST');
document.body.appendChild(form);
dojo.io.iframe.send({
url: "CSVexport.php",
form: form,
method: "POST",
content: {exp: str},
timeout: 15000
});
document.body.removeChild(form);
}
);
CSVexport.php：
<?
$time = time();
header("Pragma: public");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=\"grid_$time.csv\"");
$exportedData = $_POST['exp'];
echo $exportedData;
?>

我在使用 servlet 作为后端的 EnhancedGrid 中使用 Exporter 插件时遇到了困难。最后我通过使用 iFrame 使它工作：

});
};
<!-- Data Export Handler -->

dojo.ready(function(){

grid.startup();
});

我写了一篇博文，这样我就不必再搜索了。
PS：建议仅将 iFrame 用于内部/内部 Web 应用程序。

我正在寻找相同的东西并得到你的问题，但我找到了答案......
您必须为 dojox.Enhancedgrid 使用 Exporter 插件
“导出器插件提供了将网格数据导出为给定格式的功能”。
