  1. POChange iframe source from another iframe
    text
    copied!<p>Ok, I have 2 iframes inside a parent page (for whatever reason).</p> <p>I have a navigation menu on parent page, which changes the source of iframe #1... </p> <p>iFrame #1's job, is to display ANOTHER navigation menu... Like a subnavigation menu...</p> <p>Now, how can I upon clicking an li inside iFrame #1, change the source of iframe #2? They're both on the same parent page...</p> <p>Aside from failing miserably, I also get a warning from Chrome's Dev tools - </p> <p>Unsafe JavaScript attempt to access frame with URL file:///C:/website/index.html from frame with URL file:///C:/website/news/navigator.html. Domains, protocols and ports must match.</p> <p>Here's some code to make things slightly clearer:</p> <p>The HTML</p> <pre><code>&lt;!-- HTML for the parent page itself --&gt; &lt;iframe id="frameone" src=""&gt;&lt;/iframe&gt; &lt;iframe id="frametwo" src=""&gt;&lt;/iframe&gt; &lt;button onclick="onenav('test.html')"&gt;Change 1st frame&lt;/button&gt; &lt;!-- The following is the HTML that is loaded inside "frameone" --&gt; &lt;button onclick="twonav('test2.html')"&gt;Change 2nd frame&lt;/button&gt; // Javascript var one = document.getElementById('frameone'); var two = document.getElementById('frametwo'); function onenav(x){ one.src = x; } function twonav(y){ two.src = y; } </code></pre> <p>To me, this makes sense, since this is all being executed on the parent page... On loading, I query the dev tools and I can see that both, 'one' and 'two' have frame elements... The first button works, the second one, doesn't... </p>
 

Querying!
