title: JavaScript - Pop-Up Window opening only ONCE
body: <p>Need to create a javascript that opens <strong>a single</strong> window.</p>
  
  <p>Code:</p>
  
  <pre><code>document.body.onclick= function() {
      window.open(
          'www.androidhackz.blogspot.com',
          'poppage',
          'toolbars=0,
          scrollbars=1,
          location=0,
          statusbars=0,
          menubars=0,
          resizable=1,
          width=650,
          height=650,
          left = 300,
          top = 50'
      );
  }
  </code></pre>
  
  <p>What should I do? This script opens every single click on the website - I want it only once.</p>
