function checkdate(input)
{
var validformat=/^\d{2}\/\d{2}\/\d{4}$/ //Basic check for format validity
var returnval=false
if (!validformat.test(input.value))
alert("Invalid Date Format. Please correct and submit again.")
else{ //Detailed check for valid date ranges
var monthfield=input.value.split("/")[0]
var dayfield=input.value.split("/")[1]
var yearfield=input.value.split("/")[2]
var dayobj = new Date(yearfield, monthfield-1, dayfield)
if ((dayobj.getMonth()+1!=monthfield)||(dayobj.getDate()!=dayfield)||(dayobj.getFullYear()!=yearfield))
alert("Invalid Day, Month, or Year range detected. Please correct and submit again.")
else
returnval=true
}
if (returnval==false) input.select()
return returnval
}

in HTML

<form onSubmit="return checkdate(this.mydate)"><br />
<input type="text" name="mydate" /><br />
<input type="submit" value="submit" /><br /><br />
Valid date format: mm/dd/yyyy<br /><br />

Hi sonia,

To split a string, use the substring method:

string.substring(start,end)

Here string is the string from which you want to extract a substring.
start is the number specifying the position of the character at which the substring begins. (The character at start itself will be included in the substring.)
end is the number specifying the position of the character at which the substring ends. (The character at end will not be included in the substring.)

Note that the first character in the string corresponds to position 0, and the last character to position string.length-1.

Examples:

'Hello'.substring(0,2) // 'He'
'Hello'.substring(0,4) // 'Hell'

In javascript...considering your drop down list controls ID is 'dddCountry'
.......

objDropDownList = document.getElementById('dddCountry')
