Create and save a file with JavaScript
dialog, file, javascript, save
Solution
A very minor improvement of the code by Awesomeness01 (no need for anchor tag) with addition as suggested by trueimage (support for IE):
// Function to download data to a file
function download(data, filename, type) {
var file = new Blob([data], {type: type});
if (window.navigator.msSaveOrOpenBlob) // IE10+
window.navigator.msSaveOrOpenBlob(file, filename);
else { // Others
var a = document.createElement("a"),
url = URL.createObjectURL(file);
a.href = url;
a.download = filename;
document.body.appendChild(a);
a.click();
setTimeout(function() {
document.body.removeChild(a);
window.URL.revokeObjectURL(url);
}, 0);
}
}
Tested to be working properly in Chrome, FireFox and IE10.
In Safari, the data gets opened in a new tab and one would have to manually save this file.
Problem
I have data that I want to write to a file, and open a file dialog for the user to choose where to save the file. It would be great if it worked in all browsers, but it has to work in Chrome. I want to do this all client-side. Basically I want to know what to put in this function: ``` saveFile: function(data) { } ``` Where the function takes in data, has the user select a location to save the file, and creates a file in that location with that data. Using HTML is fine too, if that helps.
