Validating date java

This is to prevent attacks, bad data, and simple user error.

This tutorial will explain the basics of setting up validation with Spring MVC.

For numeric fields, there is a convenient way to validate a value range, but we want to select to run a custom validation script.

After the “Edit” button is clicked, a new window will open that allows us to edit the new script: This script also includes a check for an empty string, so that the user can wipe out a wrong string and start from scratch.

Prerequisites: You should have a basic understanding of how to submit forms using Spring MVC.

If you do not already understand Spring MVC basics, follow some of my other Spring tutorials first. To get started, we first need a couple JARs in our classpath.

The code presented below would then be used for letting the user change their password.HTML5 defines a variety of new input types: sliders, number spinners, popup calendars, color choosers, autocompleting suggest boxes, and more.The beauty of these elements is that you can use them now: for browsers that don't support a particular input type, there is automatic fallback to standard textfields.As I mentioned before, information is passed to the validation function in the event object, and in the code we see that the member ‘value’ is used to communicate the current value of the field.The member ‘rc’ (or return code) is used to communicate back if the validation was successful or not.
