Validating a form in javascript

This validator depends on the integer validator which must also be in the field's depends attribute.float Range - validates that a float field is within a specified range Requires min and max variables to specify the range.

To enable it, you simply set the validate=”true” property for the action, and that’s it : D Struts Validator can automatically generate Javascript code for validating your forms at the client-side (server-side validation will also be performed no matter if client-side validation is enabled or not).

If no pattern is specified the default short date format is assumed.

The difference between using the date Pattern Strict and date Pattern variables is that date Pattern Strict checks additionally that the input data is the same length as the pattern specified (so for example 1/1/2004 would fail with a pattern of MM/dd/yyyy). Deprecated, use int Range, float Range or double Range.

As all Struts components, Validator is configured by XML files, and it’s designed to be modular.

In Expresso, Validator has been modified to use the handle state name instead of the form name for identifying the forms to validate, simplifying the use of multi-page forms.
