Just to add something to dhaval's function: it's not bullet proof for any browser compliant with Javascript Filesystem. If you use it with Chrome and your path is an empty string, it will fail, because apparently, with Chrome, using split() on an empty string returns a one element array, the one element being an epmty string itself, which then causes the directory creation to fail. I modified it in order to correct the problem (there also some other not related changes, for my own purposes):

function createPath(fs, path, callback) {
    var dirs = path.split("/").reverse();
    var root = fs.root;

    var createDir = function(dir) {
        if (dir.trim()!="") {
            root.getDirectory(dir, {
                create: true,
                exclusive: false
            }, success, function(dir) {
                error("failed to create dir " + dir);
            });
        } else {
            callback();
        }
    };

    var success = function(entry) {
        root = entry;
        if (dirs.length > 0) {
            createDir(dirs.pop());
        } else {
            callback();
        }
    };

    createDir(dirs.pop());
}
