使用Javascript从Destop应用程序导出到Excel

Question

I have an application. Please see the screenshot. I need to Export table data to Excel using JavaScript. I have tried to export table data with following JavaScript code

function ExportToExcel(){
        var htmltable= document.getElementsByTagName("table")[0];
   var html = htmltable.outerHTML;
   window.open('data:application/vnd.ms-excel,' + encodeURIComponent(html));
}

This code is working for a browser but for this application is not working.

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

I think above line need to be change for native browser. Anyone could help me please. Thanks !

Remark : the author is referring to a "Native Browser" which in his case is a browser control that is embedded inside of another desktop software product.

This function works for me in Chrome, Firefox. I am not sure about IE or Edge.

 function ExportToExcel() { var htmltable = document.getElementsByTagName("table")[0]; if (window.chrome && !window.opr) { // works for chrome var tableHtml = "<table border='1'>" + htmltable.innerHTML + "</table>"; var a = document.createElement('a'); a.href = 'data:application/vnd.ms-excel' + ', ' + table_html; a.download = "abc.xls'; //setting the file name a.click(); } else { var html = htmltable.outerHTML; window.open('data:application/vnd.ms-excel,' + encodeURIComponent(html)); } }
