title: how to make a link click to stay on same page
body: <p>I have the following code:</p>
  
  <pre><code>&lt;area href="/?22" shape="poly" coords="438,388,561,211"&gt;
  &lt;area href="/?23" shape="poly" coords="338,43,61,21"&gt;
  </code></pre>
  
  <p>when it's clicked the link send the "signal" and working fine, but the page change to:</p>
  
  <pre><code>http://192.168.0.177/?22 
  </code></pre>
  
  <p>or</p>
  
  <pre><code>http://192.168.0.177/?23 
  </code></pre>
  
  <p>and I want to keep the page to:</p>
  
  <pre><code>http://192.168.0.177
  </code></pre>
  
  <p>it's there a way/hack to click the link to send the signal but the page remain and of course to not refresh?</p>
  
  <p>Thank you so much!</p>
