title: how to set the variable for creating a clickTag in Javascript
body: <p>how do I set up the variable in order to implement a clickTag in Javascript for an HTML5 banner ad? How do I get a reference to the URL that is set in which the banner clicks out to? I know how to do this in AS3. I'm new to programming &amp; esp to Javascript. I am NOT using Swiffy nor am I using Flash &amp; the <code>&lt;canvas&gt;</code>. I am using Google Web Designer with a generic environment. </p>
  
  <p>inside my function I have </p>
  
  <pre><code>mainCTAClickOut= function (e) {
  
  var clickTag = "?";  //here is where I'm having a problem
  
  window.open(window.clickTag,  "_blank");
  
  }
  </code></pre>
  
  <p>What am I missing?</p>
