Script for validating a form in javascript my friend is dating a minor

Rated 4.3/5 based on 851 customer reviews

I can't find anywhere how to access the actual form using the javascript language.

I feel like I need to enter something different than document.forms[0] but what data is required in order to access the document?

I know there are other ways to do this but I am just trying to figure out how to do this specific thing.

When capturing information for insertion into a database, or use in other processing, it's important to control what the user can enter.

This script only confirms that the input format is correct and that each individual value falls within its allowed range.

It does not check for leap years or invalid dates at the end of short months.

Basically, for each of the regular expression tests, an array is returned holding each component of the pattern that we've matched.

For example, when the date is checked, the return value, , is an array with elements 1 through 3 containing the day, month and year components of the input string.

To make the web browser check that a field is not empty, you will need to add a call to your validation function when the form is submitted.

As we've seen before, creating re-usable functions can significantly reduce the size of your Java Script code.

These functions can even be included from an external javascript file so that the browser can cache them, and so the programmer isn't always copying and pasting.

The time field will allow input starting with 'hh:mm' following by an optional 'am' or 'pm'. The code behind the form is as follows: For each field in the form (first the dates, then the time field), a check is made as to whether the input is blank.

If not, the input is compared to the regular expression.
