<script> and <noscript> tags and unobtrusive JavaScript

Hi there,

can't you just use <script> and <noscript> tags to control what users see with disabled JavaScript instead of adding HTML with the jQuery .append() method?

Thanks!

It's not an "instead" situation — you would typically use these things together.

Anything written in jQuery will only run if scripting is enabled, and you might combine this with code inside a <noscript> tag to display something else when it is not enabled.

Thanks! But why can't you just put HTML within a <script> tag? Wouldn't that be easier than inserting HTML with JavaScript/jQuery?

I see what you mean, but I guess the creators of HTML probably expected that if you use scripting at all, you probably want to add a some functionality in addition to just displaying some HTML elements, so they left it up to the script code to do that. Not all scripts add anything to the HTML at all.
