Here is some Javascript embedded into a Joomla Page using the Sourcerer plugin

 

 {source} 

 <?php

$myscript = "alert('This is JavaScript');";

$doc->addScriptDeclaration( $myscript );

?>

  {/source}

 

This will add it to the <head> of the document. If you just want the javascript code in the <body> of the document, just put the raw javascript inside the source tags, where you want it in the document. You need to have the <script> and </script> also.

 

 

{source} 

<script type="text/javascript">

document.write('This text is placed through <strong>JavaScript</strong>!');

</script>

  {/source}
