How to handle JS that cannot pass W3C verification_javascript skills

Here's how:
Add a type attribute to all <script> tags. For example: <script type="text/javascript">. <br>Encapsulate script content in comment statements. For example: <br></p> <div class="codetitle"> <span><a style="CURSOR: pointer" data="84933" class="copybut" id="copybut84933" onclick="doCopy('code84933')"><u>Copy code</u></a></span> The code is as follows:</div> <div class="codebody" id="code84933"> <br><script type="text/javascript" ><!-- <BR>...Js code is located here... <BR>//--> <br></script>

Whether it is HTML Still an XHTML page, making these changes will not resolve all validation errors. The script will continue to run normally.
