/*
* To use this method, follow the below steps
* Step 1.) include a empty div tag
*
* ex:
* <table border="0" cellpadding="3" cellspacing="0" width="370">
* <tr>
* <td align="left" colspan="3" width="370"><div id="errorMessage"></div></td>
* </tr>
* </table>
*
* at the top just after the grey separator tag.
*
* Step 2.) add a hidden variable with name and id as "required" in the form to be validated
*
* ex: <input type=hidden name="required" id="required" value="companyName,companyPassword"/>
*
* Step 3.) include the validator.js in the jsp using the below scriplet tag
* <SCRIPT language="JavaScript" src="/portal/jslib/validator.js"></SCRIPT>
*
* Step 4.) call the utility function using checkform(frmname)
*
* ex:
* <form action='action_url' method="POST" name="frmName" id="frmId" onsubmit="return checkform(this);" >
*
* Now the validator will validate for required fields in the form for text, email (identified by the field name as email), single select
* and multi-select fields
* (further field validations will be added in due course)
