Export html table data to Excel using JavaScript / JQuery is not working properly in chrome browser

Excel export script works on IE7+, Firefox and Chrome.

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

Just create a blank iframe:

<iframe id="txtArea1" style="display:none"></iframe>

Call this function on:

<button id="btnExport" onclick="fnExcelReport();"> EXPORT </button>

Datatable plugin solves the purpose best and allows us to export the HTML table data into Excel , PDF , TEXT. easily configurable.

            };

            var format = function(s, c) {
                return s.replace(/{(\w+)}/g, function(m, p) {
                    return c[p];
                })
            };

            htmls = "YOUR HTML AS TABLE"

            var ctx = {
                worksheet : 'Worksheet',
                table : htmls
            }


            var link = document.createElement("a");
            link.download = "export.xls";
            link.href = uri + base64(format(template, ctx));
            link.click();
