title: Open link from variable in iframe
body: <pre><code>    &lt;script language="Javascript" type="text/javascript"&gt;
      function Next(){
          var randp = Math.floor(Math.random()*3);
          switch(randp){
              case 0:
                  var websel = "http://w3schools.com";
                  break;  
              case 1:
                  var websel = "http://www.bbc.com/";
                  break;
              case 2:
                  var websel = "http://en.wikipedia.org/wiki/BBC";
                  break;
              default:
                  document.write("Error SWITCH(randp) " + randp + " ");
                  break;
          }
      }
      &lt;/script&gt;
  
      &lt;iframe name="iframea" src="http://w3schools.com" seamless="seamless" scrolling="auto" height="560px" width="1080px" align="middle" scale="1.5"&gt;&lt;/iframe&gt; 
  
   &lt;input type="button" value="Next" onClick="Next()"&gt;
  </code></pre>
  
  <p>Sorry for the basic question. What would I need to add to have the next button open a link (the link being a variable from a function) with the target as the iframe.
  Thanks</p>
