Question: If the user's browser cannot execute JavaScript code, can I display a warning for the user?
Answer:
Yes, you can display a special warning for users of JavaScript-incapable browsers.
Place your warning text between the tags
<NOSCRIPT>
and
</NOSCRIPT>.
Here's an example:
<NOSCRIPT> <H3>This page uses JavaScript</H3> <ul> <li>Please use a JavaScript-aware browser. <li>Make sure that JavaScript is enabled. </ul> </NOSCRIPT>JavaScript-enabled browsers will ignore everything between
<NOSCRIPT>
and
</NOSCRIPT>.
Browsers that cannot execute JavaScript will display your message on the page.
The message will be presented to users who disabled JavaScript –
as well as those users whose browsers have no JavaScript support at all.
Historical note:
The<NOSCRIPT>
tag was not supported by Netscape Navigator 2.
Therefore, your message would be visible to Netscape Navigator 2 users
even if JavaScript was enabled in their browser.
