title: How to get to know which anchor link being clicked using javascript?
body: <p>Sorry I am new to JavaScript.</p>
  
  <p>Says that <em>a.html</em> has two same anchor links (<code>&lt;a href="b.html"&gt;b&lt;/a&gt;</code>). The anchor links are uneditable but we could add JavaScript to the <em>a.html</em>.</p>
  
  <p>Except for dynamic adding <code>onclick</code> event, any other ways could get to know which anchor link being clicked?</p>
