title: How do I escape characters in href of anchor tag
body: <p>I want to escape three characters these are </p>
  
  <ol>
  <li>single quote (')</li>
  <li>double quote (")</li>
  <li>backslash ()</li>
  </ol>
  
  <p>my href value is
  <code>test.html?key="test' me'"&amp;event=3</code></p>
  
  <p>I want to fix it as we do in <code>php</code> by calling <code>addslashes function</code></p>
  
  <pre><code>&lt;a href="test.html?key="test' me'"&amp;event=3"&gt;test&lt;/a&gt;
  </code></pre>
  
  <p><strong>NOTE: I need a dynamic way of doing it</strong></p>
