Abstract

A system and method for performing client-side input validation may include a JavaServer Faces (JSF) environment having parameters indicating whether to enable or disable client-side validation for a given application, and one or more validation functions for validating required fields, minimum and maximum values, regular expressions, input lengths, or other input parameters.

Claims

1. A method for performing client-side input validation in a client-server environment, comprising:

receiving a web page that includes at least one input component, the input component associated with at least one validator tag defining a valid input for the input component;

presenting the web page to a user, the displayed page including at least one input field corresponding to the input component; and

invoking a renderer that generates source code from the validator tag, the generated source code, the generated source code operable to execute a validation script that determines whether an input received in the input field satisfies the valid input definition.

2. The method of claim 1, wherein the generated source code and the validation function include JavaScript code.

3. The method of claim 2, further comprising receiving a plurality of JavaScript validation functions, each of which perform validation for one or more input types.

4. The method of claim 1, further comprising identifying one or more attributes associated with the validator tag, wherein the source code that invokes the validation function is rendered based on the identified attributes.

5. The method of claim 4, the attributes including an identification of the validation function and one or more parameters defining the valid input.

6. The method of claim 5, the parameters including one or more of a regular expression, a numerical range, a date range, a minimum string length, and a maximum string length.

7. The method of claim 1, the generated source code further operable to execute the validation script by providing, to the validation script, one or more parameters associated with the valid input and one or more messages associated with an invalid input.

8. The method of claim 7, further comprising displaying at least one of the messages when the received input does not satisfy the valid input definition.

9. The method of claim 1, wherein the input component includes a JavaServer Faces (JSF) input component.

10. A system for performing client-side input validation in a client-server environment, comprising:

a plurality of validators, each of which extend a base validator to implement respective validator tags;

a plurality of validator renderers, each of which extend a base validator renderer to implement a renderer for a respective one of the validator tags; and

a client system that receives a web page including at least one input component, the input component associated with at least one of the validator tags, the client system operable to invoke one or more of the validator renderers that implement the renderer for the at least one validator tag, wherein the invoked renderer generates source code that executes one of a plurality of validation scripts that validate an input relating to the at least one validator tag.

11. The system of claim 10, the at least one validator tag including one or more attributes defining a valid input for the input component, the validation script operable to determine whether an input received for the input component satisfies the valid input definition.

12. The system of claim 11, the client system further operable to invoke one or more component renderers that renders an input field corresponding to the JSF input component, wherein a user provides the received input to the rendered input field.

13. The system of claim 12, the at least one input field including one or more of a text box, a radio button, a check box, a multiple select box, a single select box, a combo box, a list box, and a date picker.

14. The system of claim 11, wherein the generated source code includes a JavaScript function call having one or more parameters based on the validator tag attributes.

15. The system of claim 10, further comprising at least one input script operable to iteratively process the validator tags associated with the JSF input component.

16. The system of claim 15, wherein the generated source code, the validation scripts, and the input script include JavaScript code.

17. The system of claim 10, further comprising a resource module that includes one or more messages to be passed as parameters to the validation scripts.

18. The system of claim 10, the validators performing validation for one or more of a regular expression, a numerical range, a date range, a minimum string length, and a maximum string length.
