title: Javascript / Select elements without a Class
body: <p>I've got a Calendar-table (created as a Javascript Object). Its top row involves both the days of previous and current month. I marked the days of the current month with Class "Out". 
  Now I need to select the days of the previous month in order to make a Statement
       <strong><em>if {The top table row has the cells without Class "Out", I don't want to show them</em></strong>}
  How can I do that using native Javascript? In other words it seems like I need an analogue of <strong>.not()</strong> in JQuery.</p>
