Following are the keywords for validation

validateblank:-for checking of blanlk, tag should not be left blank

validatemail:-Checking for mail

validatedate:-Validation for date



HOW TO USE



pass parameter to function chkForm()

parameter should 

first parameter should be name of form eg 'myform'

second should be tag for which you wnat to do validation eg 'myinput'

third parameter is type of validaation u want to done eg "validatemail"

fourth is message test you want to show if error found

FOR DOING VALIDATION ON MORE THAT ONE THAG

same as about after finishing for first tag start same for second tag by puting comma and continu

same way more than one validation can be dont on same input tag

example 

<form name="myform" action="" method="post" onsubmit="chkForm('myform','myname','validatedate','Please Enter Correct Date','myname','validateblank','Please Enter Some Value')">
