没有对话框提示的Internet Explorer中的Excel下载

Question

我正在尝试使用javascript实现下载excel功能

function fnExcelReport() {
    var tab_text = "<table border='2px'><tr bgcolor='#87AFC6'>";
    var textRange;
    var j = 0;
    tab = document.getElementById('table'); // id of table

    for (j = 0; j < tab.rows.length; j++) {
        tab_text = tab_text + tab.rows[j].innerHTML + "</tr>";
        //tab_text=tab_text+"</tr>";
    }

    tab_text = tab_text + "</table>";
    tab_text = tab_text.replace(/<A[^>]*>|<\/A>/g, ""); //remove if u want links in your table
    tab_text = tab_text.replace(/<img[^>]*>/gi, ""); // remove if u want images in your table
    tab_text = tab_text.replace(/<input[^>]*>|<\/input>/gi, ""); // reomves input params

    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE ");
    if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) // If Internet Explorer
    {
        txtArea1.document.open("txt/html", "replace");
        txtArea1.document.write(tab_text);
        txtArea1.document.close();
        txtArea1.focus();
        sa = txtArea1.document.execCommand("SaveAs", true, "Say Thanks to Sumit.xls");
    } else //other browser not tested on IE 11
        sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));

    return (sa);
}

它在chrome中工作正常。但是在Internet Explorer中，出现了“另存为”对话框。有没有办法下载文件而无需打开对话框

[由IE浏览器显示的另存为对话框，您无法从代码中控制它。
