javascript - 导出时重命名下载文件

Question

我单击一个按钮，该函数运行以导出到 .xls 文件，但其名称是 download.xls - 我希望能够更改下载名称... 有谁知道如何添加此功能...

这是按钮的代码

<li class="button"><a href="javascript:;" onclick="fnExcelReport();"
    style="background-color: #4cae4c;">Export EXCEL</a></li>

这是脚本

function fnExcelReport()
{
    var tab_text = "<table border='2px'>"; 
        tab_text += "<tr bgcolor='#eeeeee' height='50'><th colspan='12' ";
        tab_text += "style='text-align:center; font-size:20px;'>COMPLETED "
        tab_text += "TRIPS </th></tr><tr bgcolor='#bf997e' height='50'"
        tab_text += "color='#FFFFFF'>"; 

    var i   = 0;
    var tab = document.getElementById('completed_trips_prov'); // id of table

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

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

    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE "); 

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

    return (sa);
}
