dolphin currently processing noscript division

Why are Dolphin Browser and the Default Android Browser reading the <noscript> section in the head of my page, even though JavaScript is enabled in those browsers? This issue is causing the content of the pages not to render.

In the head section, I have linked to a CSS stylesheet that sets the display to none for anything inside a div on the page when JavaScript is disabled in the browser. The CSS resides within a noscript element so that it is only applied if JavaScript is turned off.

This solution works for all desktop/laptop browsers I tested, except for Mac as I don't have access to test it. It also works on Android with Firefox and Opera, but Dolphin and the default Android browsers are still reading the CSS stylesheet within the noscript section, resulting in the page/site not rendering correctly.

I confirmed this by removing the stylesheet link from the head section, which allowed the pages to render correctly in those problematic browsers.

Is there any way to make these browsers respect the noscript tags in the head section?

UPDATE: This is using HTML5 - the noscript tag in the head is allowed: http://www.w3.org/TR/html5/the-noscript-element.html#the-noscript-element

<!DOCTYPE html>
<html>
<head>
        <noscript>
            <link href="${facesContext.externalContext.requestContextPath}/css/no_javascript.css" rel="stylesheet" type="text/css" />
            <!-- Despite JavaScript being enabled in Dolphin, this link is still read -->
        </noscript>

</head>
<body>
    <noscript>
        Content within this noscript element displays correctly
    </noscript>

    <div class="no_javascript_disapear">

        Content on this page is not rendered due to Dolphin Browser ignoring the noscript tags in the head.

    </div>
</body>
</html>

// CSS within the noscript tag:
.no_javascript_disapear {display:none;}

Answer №1

Perhaps you could consider utilizing JavaScript to eliminate that stylesheet?

If not, you have the option to assign a title to your no-js stylesheet:

<link title="noJsStylesheet"  href="....css" rel="stylesheet" type="text/css" />

Then utilize this function to remove it:

for(i=0; (a = document.getElementsByTagName("link")[i]); i++) {
    if(a.getAttribute("title") == 'noJsStylesheet') a.disabled = true;
}

Although I cannot guarantee its effectiveness on this particular Dolphin version.

Answer №2

As per the HTML guidelines released as W3C recommendations, it is specified that the noscript element can only be placed inside the body tag. While some browsers may also allow it in the head, this cannot be guaranteed. Merely stating that you are using HTML5 does not change this rule; browsers have their own way of interpreting specifications, sometimes even implementing parts of HTML5 drafts selectively.

The HTML5 draft actually discourages the use of noscript altogether: "The noscript element is a crude method. There are instances where scripts could be enabled but fail to run on the page for some reason. It is therefore advisable to avoid using noscript and instead develop scripts that can switch the page from being scriptless to scripted dynamically" (followed by an illustration).

Hence, the recommended approach would be progressive enhancements: Create a functional page layout that operates without any scripting initially. Subsequently, incorporate scripting in a non-intrusive manner. This might involve applying CSS styles through scripting (which is more practical than removing existing styles).

In case of urgency, one potential solution could be inserting a script element immediately after the link element within the noscript, containing code to promptly eliminate that particular element from the document structure.

Interestingly, my trusty old Android 2.3.5 default browser appears to support noscript within the head.
