Warning Message/pop Out For Date/time
I have a form where a user need to enter date and time (2 different fields) and the time cannot be more than 12 hours old. So I want to add a warning message (most likely a pop-up
Solution 1:
<script language="JavaScript">
function validate()
{
var dateEntered = new Date( document.getElementById("Date") + " " + document.getElementById("Time") );
var dateNow = new Date();
if( dateNow - dateEntered > 1000*60*60*12 )
{
alert( "Date entered is too old." );
return( false );
}
return( true );
}
</script>
<form method=post action="blah.html" onsubmit="JavaScript: return( validate() );">
<input type=text id=Date name=Date>
<input type=text id=Time name=Time>
<input type=submit value="Submit">
</form>
