title: What does this selector mean a.listen("parsley:field:validated",this,this.reflow)?
body: <p>I'm trying to understand how the <code>Parsley.js</code> works and in the code I've found these selector:</p>
  
  <p><code>a.listen("parsley:field:validated",this,this.reflow)</code></p>
  
  <p>Does somebody know what could it mean if the css selectors and elements are divided by colons? These are not pseudo classes or elements, aren't they?</p>
  
  <p>Thank you!</p>
