    text
    copied!<p>I am trying to load a HTML snippet into a newly created iframe in the following.</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt;&lt;title&gt;Test&lt;/title&gt;&lt;/head&gt; &lt;body&gt; &lt;script type="text/javascript"&gt; var iframeId = "frame" + Math.floor((Math.random() + "") * 1000000000000).toString(); document.write('&lt;iframe height="300"' + ' width="300"' + ' frameborder="0"' + ' scrolling="no"' + ' id="' + iframeId + '"' + ' name="' + iframeId + '"' + ' allowtransparency="true"&gt;&lt;/iframe&gt;'); var iframe = document.getElementById(iframeId); var iframeContent = '&lt;!-- --\&gt;&lt;script language=\"javascript\"\&gt;&lt;/script\&gt;'; iframe.contentWindow.document.open(); iframe.contentWindow.document.write( '&lt;!DOCTYPE html\&gt;&lt;html\&gt;&lt;head\&gt;&lt;title\&gt;Test&lt;/title\&gt;&lt;/head\&gt;&lt;body\&gt;' + iframeContent + '&lt;/body\&gt;&lt;/html\&gt;'); iframe.contentWindow.document.close(); &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>When I open this document in a browser, the iframe is not loaded properly. Any thoughts on what might be causing this?</p> <p>If I set iFrameContent as</p> <pre><code>var iframeContent = '&lt;!-- --\&gt;'; </code></pre> <p>or</p> <pre><code>var iframeContent = '&lt;script language=\"javascript\"\&gt;&lt;/script\&gt;'; </code></pre> <p>the page seems to load properly.</p> <p>iframeContent is essentially a third party HTML snippet (escaped using freemarker js_string) and may contain HTML comments.</p>
