Javascript

Here is a quick javascript tutorial i did

<script type="text/javascript">
function checkDate()
{
if(!document.getElementById || !document.createTextNode) {return;}
if(!document.getElementById('date')){return;}
//define a regular expression to check the date format
var checkPattern = new RegExp("\\d{2}/\\d{2}/\\d{4}");
//get the value of the date entry field
var dateValue=document.getElementById('date').value;
//if there is no date entered, don't sen the form
if(datevalue='')
{
alert("Please enter a date");
return false
}
else
{
//tell the user to change the date syntax either until
// she presses cancel or entered the right syntax
while(!checkPattern.test(dateValue) && dateValue!=null)
{
dateValue=prompt("Your date was not in the right format. Please enter it as DD/MM/YYYY.", dateValue);
}
return dateValue!=null;
}
}
