var explorer = window.navigator.userAgent;
console.log(explorer);
//ie

}
}
function exportExcel(tableid) {
if(getExplorer()=='ie'){
var curTbl = document.getElementById(tableid);
var oXL = new ActiveXObject("Excel.Application");
var oWB = oXL.Workbooks.Add();
var oSheet = oWB.ActiveSheet;
var sel = document.body.createTextRange();
sel.moveToElementText(curTbl);
// sel.select();
sel.execCommand("Copy");

}else{
tableToExcel(tableid)
}
}
var tableToExcel = (function() {
var uri = 'data:application/vnd.ms-excel;base64,',
template = '<html><head><meta charset="UTF-8"></head><body><table>{table}</table></body></html>',
base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) },
format = function(s, c) {
return s.replace(/{(\w+)}/g,
function(m, p) { return c[p]; }) }
return function(table, name) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
window.location.href = uri + base64(format(template, ctx))
}
})();
