HTML Script

JavaScript makes HTML pages more dynamic and interactive. HTML and JAVASCRIPT both are different things. <script> is a tag used to put some executable code which is named as a script into the web age or HTML code.

HTML <script> tag

The <script> tag is used to define client-side scripts, such as JavaScript.

The <script> element can either contain script statements or point to an external script file via the src attribute.

JavaScript is most commonly used for image manipulation, form validation, and dynamic updating of content.

The following script will output “Hello World!” to the browser:

 document.write(" Hello World!");</script >

HTML <noscript> tag

The <noscript> tag provides alternative content when scripting cannot be used, such as when scripting is disabled in the browser, or when the browser does not support client-side scripting.

The <noscript> element can contain all elements found in the body element of a normal HTML page.

The content of the <noscript> element will only be displayed if the browser does not support scripting or if scripting is disabled

 document.write ( " Hello World! " ) </script>< noscript >Sorry, your browser does not support JavaScript !</noscript>

JavaScript experience (from this site’s JavaScript tutorial)

JavaScript example code:

JavaScript can be output directly in HTML:

document . write ( " <p>This is a paragraph.</p> " ) ;

JavaScript event response example:

< button type = " button " onclick = " myFunction() " > click me! </ button >

JavaScript handles HTML styling:

document . getElementById ( " demo " ) . style . color = " #ff0000 " ;
