HTML Advanced tutorial 22 : HTML Scripts

HTML script Element
The <script> tag is used to define a client-side script, such as a JavaScript and JQuery. The script element either contains scripting statements or it points to an external script file through the src attribute. The required type attribute specifies the MIME type of the script. Common uses for JavaScript are image manipulation, form validation, and dynamic changes of content.

For Example

<script type="text/javascript">
document.write("Hello!")
</script>

The script above writes Hello! to the HTML output.

HTML noscript Element
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:

For example

<script type="text/javascript">
document.write("Hello!")
</script>
<noscript>This is not inside Script!</noscript>
