<p><b>New page</b></p><div>The <script> tag has three applications:<br />
<br />
# When used in the <head> element, it can contain JavaScript statements.<br />
# When used in the <body> element, it can contain JavaScript statements. This use is '''not''' recommended.<br />
# When used in the <head> element, it can be used to load external JavaScript files.<br />
<br />
== In the <head> Element ==<br />
<br />
<pre><br />
<!doctype html><br />
<html><br />
<head><br />
<script><br />
window.alert("JavaScript is active");<br />
</script><br />
</head><br />
<body><br />
</body><br />
</html><br />
</pre><br />
<br />
== In the <body> Element ==<br />
<br />
Again, this usage is '''not''' recommended. Best practices dictate that content and function remain separate.<br />
<br />
<pre><br />
<!doctype html><br />
<html><br />
<head><br />
</head><br />
<body><br />
<button onclick="alert('JavaScript is active');">Click me</button><br />
</body><br />
</html><br />
</pre><br />
<br />
== In the <head> Element to Load External JavaScript Files ==<br />
<br />
<pre><br />
<!doctype html><br />
<html><br />
<head><br />
<script src="myscript.js"></script><br />
</head><br />
<body><br />
</body><br />
</html><br />
</pre><br />
<br />
This method does '''not''' work within the <body> tag. If you want to load external JavaScript files, you must do so from within the <head> element.<br />
<br />
== HTML Compliance ==<br />
<br />
=== HTML5 ===<br />
<br />
In Javascript, the proper notation for HTML5 has no [[attribute]]s:<br />
<br />
<pre><br />
<script><br />
...JavaScript statements...<br />
</script><br />
</pre><br />
<br />
=== HTML4 ===<br />
<br />
When used in [[HTML4]] or [[XHTML]], the <script> tag '''must''' include the [[type]] attribute:<br />
<br />
<pre><br />
<script type="text/javascript"><br />
...JavaScript statements...<br />
</script><br />
</pre><br />
<br />
=== Deprecated Attributes ===<br />
<br />
At one point, the ''language="JavaScript"'' attribute was required. It has long been [[deprecated]] and should not be used.<br />
