date validation with regex

[srowe]

I am using a regex expression to validate that the date has a 4 digit year.

I am passing a string to this function and it is not working correctly.

Can someone help me with this?

When I pass 07/29/80 it returns false;
when I pass 07/29/1980 it returns false;



function isDate()
{
var dt = arguments[0];
var dateExpression = '^\d{2}\/\d{2}\/\d{4}$';
var dtval = dt.match(dateExpression);
if(!dtval){
return false;
}else{
return true;
}
}

You declared your dateExpression as a string, not a regular expression, try...

Code: Select all

var dateExpression = /^\d{2}\/\d{2}\/\d{4}$/;

Perfect!
