How to determine whether Microsoft Excel or Open Office is installed on the system using jquery

问题

I needed to export data of a table to Excel. I got a solution as below:

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

In the above example, it allows you to generate xls file when Microsoft Excel is installed on the system but I have OpenOffice installed on my system, so when I add the line

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

instead of

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

then it generates the .ods file.

I need to determine whether Excel or Open Office is installed so that I can put the condition for the above two lines using jQuery or Javascript.

EDIT:

Can i put back to back the two conditions, is that a harm?

$("#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();
});

ANOTHER EDIT: Just tried this solution on IE8, it doesn't work. Any other alternatives for this solution or this can be fixed to work on IE?

As far as i know there exists a vague way , you can check the existing Mime types to ensure the presence

eg: 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);
            }
