Javascript can access MySQL...but generally only on the server. I've done it with Rhino, a java based javascript interpreter. Just included the MySQL driver, and its available. I imagine you could probably do this with an applet as well.

using Rhino, it would be something like this:

var DATABASE = {

    database: 'blog_development',
    host: 'localhost',
    username: 'dbuser',
    password: 'dbpass'

};

function ArticleModel(properties) {
  for (var p in properties) {
    this[p] = properties[p];
  }
}

ArticleModel.findAll = function() {
    var results = [];

    var jsConnectionObj = new Packages.MysqlConnection();
    c = jsConnectionObj.open(DATABASE.host,
                             DATABASE.database,
                             DATABASE.username,
                             DATABASE.password);

    if (c) {
      var s = c.createStatement();
      s.executeQuery("SELECT * FROM articles;");
      var rs = s.getResultSet();
      while (rs.next()) {
          results.push(new ArticleModel({
            id: rs.getInt("id"),
            title: rs.getString("title"),
            body: rs.getString("body")
          }));
      }
      rs.close();
      c.close();  
      return results;
    }

    throw new Error('could not connect to database');      
};
