If you are generating data on the client side (like a CSV from a table), you can use Blob objects and URL.createObjectURL() . javascript

$('#exportCsv').on('click', function() { var csvContent = "Name,Age\nJohn Doe,30\nJane Smith,25"; var blob = new Blob([csvContent], { type: 'text/csv' }); var url = window.URL.createObjectURL(blob); var $a = $(' ') .attr('href', url) .attr('download', 'data.csv') .appendTo('body'); $a[0].click(); // Cleanup memory window.URL.revokeObjectURL(url); $a.remove(); }); Use code with caution. 5. Critical Limitations & Best Practices How to download file using anchor tag - Stack Overflow

Sometimes you don't have an existing anchor tag in your HTML. You can create a "hidden" anchor tag in memory, trigger a click, and then remove it. javascript

Set the necessary attributes $tempAnchor.attr('href', url); $tempAnchor.attr('download', fileName); // 3. Append to body (required for some browsers), trigger click, and remove $('body').append($tempAnchor); $tempAnchor[0].click(); // Note: use [0] to get the native DOM element $tempAnchor.remove(); } Use code with caution. 4.
