Download File Using Javascript/jQuery
I have a very similar requirement specified here.

But

Most Complete and Working (Tested) Code for Downloading Data For FireFox, Chrome and IE Code is Following. Assume that Data is in texarea field, that has id='textarea_area' and filename is name of file where data will be downloaded.
function download(filename) { if (typeof filename==='undefined') filename = ""; // default value = document.getElementById('textarea_area').value; filetype="text/*"; extension=filename.substring(filename.lastIndexOf(".")); for (var i = 0; i < extToMIME.length; i++) { if (extToMIME[i][0].localeCompare(extension)==0) { filetype=extToMIME[i][1]; break; } } var pom = document.createElement('a'); pom.setAttribute('href', 'data: '+filetype+';charset=utf-8,' + '\ufeff' + encodeURIComponent(value)); // Added BOM too pom.setAttribute('download', filename); if (document.createEvent) { if (navigator.userAgent.indexOf('MSIE') !== -1 || navigator.appVersion.indexOf('Trident/') > 0) { // IE blobObject = new Blob(['\ufeff'+value]); window.navigator.msSaveBlob(blobObject, filename); } else { // FF, Chrome var event = document.createEvent('MouseEvents'); event.initEvent('click', true, true); pom.dispatchEvent(event); } } else if( document.createEventObject ) { // Have No Idea var evObj = document.createEventObject(); pom.fireEvent( 'onclick' , evObj ); } else { // For Any Case pom.click(); } }and then just call
<a href="javascript:download();">Download</a>For Download Initiating.
Array for setting correct MIME type for download dialog CAN BE following:

I have had good results with using a FORM tag since it works everywhere and you don't have to create temporarily files on server. The method works like this.
On the client side (page HTML) you create an invisible form like this
<form method="POST" action="/download.php" target="_blank" id="downloadForm"> <input type="hidden" name="data" id="csv"> </form>Then you add this Javascript code to your button:
$('#button').click(function() { $('#csv').val('---your data---'); $('#downloadForm').submit(); }The on the server-side you have the following PHP code in
download.php:<?php header('Content-Type: text/csv'); header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename=out.csv'); header('Content-Transfer-Encoding: binary'); header('Connection: Keep-Alive'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . strlen($data)); echo $_REQUEST['data']; exit();You can even create zip files of your data like this:
<?php $file = tempnam("tmp", "zip"); $zip = new ZipArchive(); $zip->open($file, ZipArchive::OVERWRITE); $zip->addFromString('test.csv', $_REQUEST['data']); $zip->close(); header('Content-Type: application/zip'); header('Content-Length: ' . filesize($file)); header('Content-Disposition: attachment; filename="file.zip"'); readfile($file); unlink($file);The best part is it does not leave any residual files on your server since everything is created and destroyed on the fly!

These functions are used in stacktrace.js:
/** * Try XHR methods in order and store XHR factory. * * @return <Function> XHR function or equivalent */ var createXMLHTTPObject = function() { var xmlhttp, XMLHttpFactories = [ function() { return new XMLHttpRequest(); }, function() { return new ActiveXObject('Msxml2.XMLHTTP'); }, function() { return new ActiveXObject('Msxml3.XMLHTTP'); }, function() { return new ActiveXObject('Microsoft.XMLHTTP'); } ]; for (var i = 0; i < XMLHttpFactories.length; i++) { try { xmlhttp = XMLHttpFactories[i](); // Use memoization to cache the factory createXMLHTTPObject = XMLHttpFactories[i]; return xmlhttp; } catch (e) { } } } /** * @return the text from a given URL */ function ajax(url) { var req = createXMLHTTPObject(); if (req) { try { req.open('GET', url, false); req.send(null); return req.responseText; } catch (e) { } } return ''; }讨论(0) -
Only seven years later here comes a one line jQuery solution using a form instead of an iframe or link:
$('<form></form>') .attr('action', filePath) .appendTo('body').submit().remove();I've tested this in
- Chrome 55
- Firefox 50
- Edge IE8-10
- iOS 10 (Safari/Chrome)
- Android Chrome
If anyone knows of any downsides with this solution I'd be very happy to hear about them.
Full demo:
<html> <head><script src="https://code.jquery.com/jquery-1.11.3.js"></script></head> <body> <script> var filePath = window.prompt("Enter a file URL","http://jqueryui.com/resources/download/jquery-ui-1.12.1.zip"); $('<form></form>').attr('action', filePath).appendTo('body').submit().remove(); </script> </body> </html>讨论(0) -
Maybe just have your javascript open a page that just downloads a file, like when you drag a download link to a new tab:
Window.open("https://www.MyServer. Org/downloads/ardiuno/WgiWho=?:8080")With the opened window open a download page that auto closes.

I use @rakaloof's solution without JQuery (because you don't need it here). Thank you for the idea! Here is a vanillaJS form-based solution:
const uri = 'https://upload.wikimedia.org/wikipedia/commons/b/bb/Test_ogg_mp3_48kbps.wav'; let form = document.createElement("form"); form.setAttribute('action', uri); document.body.appendChild(form); form.submit(); document.body.removeChild(document.body.lastElementChild);讨论(0)
