Regular expression validating date colorado dating scene

I still don't understand how to get the regular expression.

In this tutorial you will see how to use regular expressions to validate.

We use capturing groups here because you’ll probably want to capture the day and month numbers anyway.

First go to your html file and paste the following code : Here, I have a simple form.

It has an onsubmit event attached to a function called validate() that we are going to create later inside this form there are three inputs one for our phone number another one is for postal codes and the third and the last one is a submit button that is going to submit the form after we are done filling it. It contains only the code that validates the phone number.

You want to validate dates in the traditional formats mm/dd/yy, mm/dd/yyyy, dd/mm/yy, and dd/mm/yyyy.

You want to use a simple regex that simply checks whether the input looks like a date, without trying to weed out things such as February 31You might think that something as conceptually trivial as a date should be an easy job for a regular expression. Because dates are such an everyday thing, humans are very sloppy with them. To somebody else, it may be the first working day of the year, if New Year’s Day is on a Friday.

Here I have added a new variable called postal Code to fetch the postal code from the form then created another variable to store the postal code regular expression which we will be discussing in a second.

Then I used the test function to test my string against the regular expression and print the result in an alert.

Now let’s jump to the regular expression itself: UK postal code examples : EC1A 1BB W1A 0AX M1 1AE B33 8TH CR2 6XH DN55 1PT So, 1 or 2 alphabetic characters, followed by 1 or 2 digits, then a space and one digit and exactly two alphabetic characters.

So here is the Regular expression pattern:/^[A-Z][0-9] ?

Solutions 3 through 6 restrict the month to numbers between 1 and 12, and the day to numbers between 1 and 31.

We use alternation (see Recipe 2.8) inside a group to match various pairs of digits to form a range of two-digit numbers.

Etc.), you see a form contains a number of fields and each one of these fields has to be filled in with specific data such as Email, Zip code, phone number and a password with specific conditions.
