For hiding JavaScript codes from old browsers:
Add "<!--" without the quotes in the code just after the <script> tag.
Add "//-->" without the quotes in the code just before the <script> tag.
Old browsers will now treat this JavaScript code as a long HTML comment. While, a browser that supports JavaScript, will take the "<!--" and "//-->" as one-line comments.
