jQuery. Select all the elements that classname starts with

You're almost there:

// selects all that start with "ses_"
var sessions = $('[class^="ses_"]');

Even though your loop should work, you could also use the

sessions.each(function(index){
    this.prepend(... // and so on
});

You can use the attribute starts with selector in jQuery: http://api.jquery.com/attribute-starts-with-selector/

Beware that it's not nearly as fast as using the regular way of selecting elements.
