I would like to know if I can create a text file and save the file in the users "Downloads" section in his/her computer using Javascript. The way my feature should work is when the user clicks the submit button, I populate the users info in the text file and then save it in his machine. I would like this to work in Google Chrome.
Is this possible? I have seen posts that specifically tell me that it is a serious security issue.
Sure you can, using the brand new APIs.
window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(window.TEMPORARY, 1024*1024, function(fs) {
fs.root.getFile('test.bin', {create: true}, function(fileEntry) { // test.bin is filename
fileEntry.createWriter(function(fileWriter) {
var arr = new Uint8Array(3); // data length
arr[0] = 97; // byte data; these are codes for 'abc'
arr[1] = 98;
arr[2] = 99;
var blob = new Blob([arr]);
fileWriter.addEventListener("writeend", function() {
// navigate to file, will download
location.href = fileEntry.toURL();
}, false);
fileWriter.write(blob);
}, function() {});
}, function() {});
}, function() {});
