Validation

It provides valuable, actionable feedback to your users with HTML5 form validation.

How it works

Here's how form validation works with MyTravel:

MyTravel uses third-party jQuery validation plugin.
HTML form validation is applied via .u-has-success and .u-has-error classes. It applies to <input>, <select>, and <textarea> elements.
MyTravel scopes the .u-has-success and .u-has-error styles to parent element, applied next to the <js-form-message>..
All modern browsers support the constraint validation API , a series of JavaScript methods for validating form controls.

With that in mind, consider the following demos for our custom form validation styles, optional server side classes, and browser defaults.

How to use?

Wrap any block in a parent element with an ID or class and add the same ID in the JS init function of the hs.validation.js plugin.

Copy-paste the following <script> near the end of your pages under JS Implementing Plugins to enable it.

                
                  <script src="../../assets/vendor/jquery-validation/dist/jquery.validate.min.js"></script>

Copy-paste the following <script> near the end of your pages under JS MyTravel to enable it.

                
                  <script src="../../assets/js/components/hs.validation.js"></script>

Copy-paste the init function under JS Plugins Init., before the closing </body> tag, to enable it.

                
                  <script>
                    $(document).on('ready', function () {
                      // initialization of form validation
                      $.HSCore.components.HSValidation.init('.js-validate');
                    });
                  </script>
