title: Multiple values passed in query string
body: <p>I am using something the below code to pass a single value via query string to my html page on button click using Javascript function.</p>
  
  <pre><code>window.location.href("somepage.html?w1=" + hello); 
  </code></pre>
  
  <p>The above code is working fine.</p>
  
  <p>But when I am trying to append second variable with this URL, nothing happens on click of the button.</p>
  
  <pre><code>window.location.href("somepage.html?w1=" + hello + "&amp;w2=" + world);
  </code></pre>
  
  <p>What am I doing wrong here?</p>
