I wish to create a text file locally on my system using javascript/jquery.
I am trying this code, but not working on my system.
Machine : Ubuntu 10.4 Chrome : 14.0.835.126
window.webkitRequestFileSystem(window.TEMPORARY, 1024*1024, function(fs) {
fs.root.getFile('~/Desktop/test.txt', {create: true}, function(fileEntry) {
alert(fileEntry.fullPath); //getting filepath
}, function() {});
}, function() {});
This is a little tricky but working
chrome.browserAction.onClicked.addListener(createFile);
createFile();
function createFile()
{
chrome.tabs.getSelected(null, function(tab) {
window.webkitRequestFileSystem(window.TEMPORARY, 1024*1024, function(fs) {
fs.root.getFile('test', {create: true}, function(fileEntry) {
fileEntry.createWriter(function(fileWriter) {
var builder = new WebKitBlobBuilder();
builder.append("Saurabh");
builder.append("\n");
builder.append("Saxena");
var blob = builder.getBlob('text/plain');
fileWriter.onwriteend = function() {
chrome.tabs.create({"url":fileEntry.toURL(),"selected":true},function(tab){});
};
fileWriter.write(blob);
}, errorHandler);
}, errorHandler);
}, errorHandler);
});
}
function errorHandler(e) {
var msg = '';
switch (e.code) {
case FileError.QUOTA_EXCEEDED_ERR:
msg = 'QUOTA_EXCEEDED_ERR';
break;
case FileError.NOT_FOUND_ERR:
msg = 'NOT_FOUND_ERR';
break;
case FileError.SECURITY_ERR:
msg = 'SECURITY_ERR';
break;
case FileError.INVALID_MODIFICATION_ERR:
msg = 'INVALID_MODIFICATION_ERR';
break;
case FileError.INVALID_STATE_ERR:
msg = 'INVALID_STATE_ERR';
break;
default:
msg = 'Unknown Error';
break;
};
Console.Log('Error: ' + msg);
}
Because of the Security Exceptions, i cannot create/modify a file on Local System. But in this code, I am actually creating a file in a directory which is allocated for Google Chrome Temporary Files and then downloading that file into my Downloads Folder.
This is the code of the popup page of a Chrome Extension.
