Question

我需要将表的数据导出到Excel。我得到了一个解决方案如下：

http://jsfiddle.net/jquerybyexample/xhYcD/

在上面的示例中，它允许您在系统上安装Microsoft Excel时生成xls文件但我在系统上安装了OpenOffice，因此当我添加行

时

 window.open('data:application/vnd.oasis.opendocument.spreadsheet,' + $('#dvData').html());

而不是

 window.open('data:application/vnd.ms-excel,' + $('#dvData').html());

然后它会生成.ods文件。

我需要确定是否安装了Excel或Open Office，以便我可以使用jQuery或Javascript为上述两行添加条件。

编辑：

我可以背靠背这两个条件，这有害吗？

$("#btnExport").click(function(e) {
    window.open('data:application/vnd.oasis.opendocument.spreadsheet,' + $('#dvData').html());
    window.open('data:application/vnd.ms-excel,' + $('#dvData').html());
    e.preventDefault();
});

另一个编辑： 刚刚在IE8上试过这个解决方案，它不起作用。可以修复此解决方案或其他任何其他替代方案以适用于IE？

据我所知，存在模糊的方式，您可以检查现有的Mime类型以确保存在

例如： application / x-msoffice for office

function GetMimeTypes () {
                var message = "";
                    // Internet Explorer supports the mimeTypes collection, but it is always empty
                if (navigator.mimeTypes && navigator.mimeTypes.length > 0) {
                    var mimes = navigator.mimeTypes;
                    for (var i=0; i < mimes.length; i++) {
                        message += "<b>" + mimes[i].type + "</b> : " + mimes[i].description + "<br />";
                    }
                }
                else {
                    message = "Your browser does not support this ";
                   //sorry!
                }

                return ( message);
            }
