Hey i am little beat confused what code is actually doing following is 2
function
downloadFile(data, filename = 'data') {
let csvData = this.ConvertToCSV(data, [
'name', 'age', 'average', 'approved', 'description'
]);
console.log(csvData)
let blob = new Blob(['\ufeff' + csvData], {
type: 'text/csv;charset=utf-8;'
});
let dwldLink = document.createElement("a");
let url = URL.createObjectURL(blob);
// let isSafariBrowser = navigator.userAgent.indexOf(
// 'Safari') != -1 & amp; & amp;
navigator.userAgent.indexOf('Chrome') == -1;
// /if Safari open in new window to save file with random filename.
// if (isSafariBrowser) {
// /
// dwldLink.setAttribute("target", "_blank");
// }
dwldLink.setAttribute("href", url);
dwldLink.setAttribute("download", filename + ".csv");
dwldLink.style.visibility = "hidden";
document.body.appendChild(dwldLink);
dwldLink.click();
document.body.removeChild(dwldLink);
}
ConvertToCSV(objArray, headerList) {
var array = typeof objArray != 'object' ? JSON.parse(objArray) :
objArray;
var str = '';
var row = "";
for (var index in objArray[0]) {
//Now convert each value to string and comma-separated
row += index + ',';
}
row = row.slice(0, -1);
//append Label row with line break
str += row + '\r\n';
for (var i = 0; i < array.length; i++) {
var line = '';
for (var index in array[i]) {
if (line != '') line += ','
line += array[i][index];
}
str += line + '\r\n';
}
return str;
}
}
