Using a javascript function to load a page in an iFrame

问题

I'm trying to use a Javascript function to load a web page in an iframe named "cake". How can I do that?

<html>
  <head>
  </head>
  <body>
    <button onclick=[function]>Load page in iframe</a>
  </body>
</html>

回答1:

function changeUrl() {
    var site = "http://www.w3schools.com";
    document.getElementsByName('iFrameName')[0].src = site;
}

    <html>
      <head>
      </head>
        <body>
          <button onclick="changeUrl()">Load page in iframe</button>
          <iframe name="iFrameName"></iframe>
        </body>
    </html>
