  • In webwork CVS /src/webapp/validationServlet.js contains a sample ValidationServlet client javascript class. It handles the communication with the validation servlet, and exposes callbacks for handling the errors. NOTE : I think we can re-work this a bit. I currently have lots of onWhatever callbacks. I think we should just have onErrors, and let the template designer do what they want with the Errors object.
    • Sample Usage
    :
    • Code Block
    The errors param for the onErrors callback is a javascript object that has this structure
    • 
var validation = new ValidationServlet('/validationServlet/client.js');
validation.onErrors = function(inputObject, errors) {
	// clear old errors
	// display new errors
}
    • The errors param for the onErrors callback is a javascript object that has this structure
      Code Block
      
class Errors {
	String[] actionErrors;
	Map<String, String[]> fieldErrors; // fieldName is the key
    } var validation = new ValidationServlet("/webworkValidationServlet"); validation.onErrors = function(inputObject, errors) { // clear old errors // display new errors
