Browser support
Currently most browsers support < p> tag.
Tag definition and usage instructions
The noscript element is used to define alternative content (text) when the script is not executed.
This tag can be used with browsers that recognize the <noscript> tag but cannot support the scripts contained within it.
Tips and Notes
Tips: If the browser supports scripts, it will not display the text in the noscript element.
Note: Browsers that cannot recognize the <script> tag will display the content of the tag on the page. To prevent browsers from doing this, you should hide the script in comment tags. Older browsers (that don't recognize <script> tags) ignore comments and thus don't write the content of the tag to the page, while newer browsers know how to execute these scripts even if they are surrounded by comment tags. !
<!--
function displayMsg()
{
alert("Hello World!")
}
//-->
</script>
