<script type="text/javascript"> ... JavaScript code ... </script>
2. Using language="JavaScript" attribute only - The Web browser will execute the script code as JavaScript:
<script language="JavaScript"> ... JavaScript code ... </script>
3. Using language="JavaScript1.8" attribute only - The Web browser will execute the script code JavaScript only if it supports JavaScript 1.7 version:
<script language="JavaScript1.8"> ... JavaScript code ... </script>
4. Using type="text/javascript" and language="JavaScript1.8" attributes - The Web browser will execute the script code JavaScript, and language="JavaScript1.8" attribute is ignored.
