Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The <noscript> tag is supported in all major browsers.

Definition and Usage

The <noscript> tag is used to provide an alternate content for users that have disabled scripts in their browser or have a browser that doesn’t support client-side scripting.

The <noscript> element can contain all the elements that you can find inside the body element of a normal HTML page.

The content inside the <noscript> element will only be displayed if scripts are not supported, or are disabled in the user’s browser.

Tips and Notes

Tip: It is also a good practice to use the comment tag to "hide" scripts from browsers without support for client-side scripts (so they don't show them as plain text):

<script type="text/javascript">
<!--
function displayMsg()
{
alert("Hello World!")
}
//-->
</script>
