Temporarily Disable Form Validation on Button Click

Introduction

Sometimes, you may need to bypass form validation, such as when rejecting a request. This can be achieved by using a Bean Shell Load Data Store. Adding a dummy section to your form and using a script can remove form validation when a specific button is clicked.

There are two methods available to implement this functionality. Below, we will explore each method, providing step-by-step guidance to help you effectively integrate them into your Joget forms.

Method 1: bypass validation by clicking on the reject button 

To bypass validation by clicking on the reject button, follow these steps:

1. Add an empty or dummy section to your form. 
2. Change the section's load Data Store to a Bean Shell Load Data Store and insert the following script.

   import org.joget.apps.app.service.AppUtil;
   import org.joget.apps.form.service.FormUtil;
   import org.joget.apps.form.model.Element;
   import org.joget.apps.form.model.Form;
   import org.joget.apps.form.model.FormData;
   import org.joget.apps.form.model.FormRowSet;
   
   public FormRowSet load(Element element, String primaryKey, FormData formData) {
       // Change this condition to suit your needs
       if ("#requestParam.process_reject#".equalsIgnoreCase("Reject")) {
           Form form = FormUtil.findRootForm(element);
           removeValidator(form, formData);
       }
       return null;
   }
   
   public void removeValidator(Element e, FormData formData) {
       e.setValidator(null);
   
       Collection children = e.getChildren(formData);
       if (children != null) {
           for (Element child : children) {
               removeValidator(child, formData);
           }
       }
   }
   
   // Call load method with injected variable
   return load(element, primaryKey, formData);

Method 2: bypass validation using a form button

To bypass validation using a button inside the form, follow these steps:

1. Add an empty or dummy section to your form. 

2. Change the section's load Data Store to a Bean Shell Load Data Store and insert the following script, replacing "disable_validation" with the ID of the select box form element and "Disable" with the option value that will disable validation.

   import org.joget.apps.app.service.AppUtil;
   import org.joget.apps.form.service.FormUtil;
   import org.joget.apps.form.model.Element;
   import org.joget.apps.form.model.Form;
   import org.joget.apps.form.model.FormData;
   import org.joget.apps.form.model.FormRowSet;
   
   public FormRowSet load(Element element, String primaryKey, FormData formData) {
       // Get disable_validation value from form data object
       String disableValidatorID = "disable_validation";
       Form form = FormUtil.findRootForm(element);
       Element disableValidatorElement = FormUtil.findElement(disableValidatorID, form, formData);
       
       if (disableValidatorElement != null) {
           // Get value of disable validator
           String[] disableValidatorValues = FormUtil.getElementPropertyValues(disableValidatorElement, formData);
           for (int i = 0; i < disableValidatorValues.length; i++) {
               System.out.println("Toggle Button Value " + i + ": " + disableValidatorValues[i]);
               // Remove validator if checkbox value = Disable
               if (disableValidatorValues[i].equalsIgnoreCase("Disable")) {
                   removeValidator(form, formData);
                   break;
               }
           }
       }
       return null;
   }
   
   public void removeValidator(Element e, FormData formData) {
       e.setValidator(null);
       
       Collection children = e.getChildren(formData);
       if (children != null) {
           for (Element child : children) {
               removeValidator(child, formData);
           }
       }
   }
   
   // Call load method with injected variable
   return load(element, primaryKey, formData);
