How to read/write local files through a web page?

Question

I am writing a html based app, and want to store and retrieve data from local file. This app will not be hosted on a web server.

Can anyone please help enlighten the topic on how can this be done?

Answer 1

You should use FileSystem API of HTML5:

window.requestFileSystem(window.TEMPORARY, 5*1024*1024, function(){
    fs.root.getFile('test.dat', {}, function(fileEntry) {
        fileEntry.file(function(file) {
            // Here is our file object ... 
        });
    });
}, errorHandler);
