Safari Issue : Downloaded file name is "Unknown" Javascript
Try this one
var a = document.createElement('a');a.setAttribute("href",URL);a.setAttribute("target", "_blank");var dispatch = document.createEvent("HTMLEvents");dispatch.initEvent("click", true, true);a.dispatchEvent(dispatch);return false;
IF the data is LOCAL -- Easy!
We just use window.URL.createObjectURL(). Let's set some globals...
//var response = Already defined by OP! Not sure what it is, but it's data to save.var mimetype = "text/csv";var filename = "purchase.csv";Now we just set the header by means of the type argument to window.URL.createObjectURL()...
a.href = window.URL.createObjectURL(new Blob([response], { encoding: "UTF-8", type: mimetype + ";charset=UTF-8",}));IF the data is on the WEB -- Still easy, just more effort!
We can do this by means of XMLHTTPRequest() to download the file data, window.URL.createObjectURL() to cast the data to a blob type with MIME type headers, and then proceed normally in setting a.download = filename; and a.click();.
An abstract function for download file data directly to the JavaScript environment...
function load(url, callback) { var xhr = new XMLHTTPRequest(); xhr.onreadystatechange = function () { if (xhr.readyState === 4 && xhr.status === 200) callback(xhr.responseText); }; xhr.open("GET", url, true);}Then download the data, build the link, and click it:
load("site.com/t.txt", function (contents) { var a = window.document.createElement('a'); a.href = window.URL.createObjectURL(new Blob([response], { encoding: "UTF-8", type: mimetype + ";charset=UTF-8", })); a.download = filename; document.body.appendChild(a); a.click(); a.remove();});
