Touch UI Validation in AEM - using jQuery and Granite UI (Part 2)

In this post, you'll know how you can validate the fields in the touch ui dialog of AEM using jQuery logic for validation and Granite UI to prompt error.

The entire logic for validation can be written in JS code as shown below which you can put in clientlibs and add the categories of clientlibs as cq.authoring.dialog

For Example: 

I am doing the validation for a phone number field which accepts only 10 digit numbers in the dialog.

(function (document, $, ns) {

    "use strict";

    $(document).on("click", ".cq-dialog-submit", function (e) {

        e.stopPropagation();

        e.preventDefault();

 

        var $form = $(this).closest("form.foundation-form"),

            symbolid = $form.find("[name='./symbol']").val(),

               message, clazz = "coral-Button ",

         patterns = {

             symboladd: /^([0-9]{10})\.?$/i

        };

        if(symbolid != "" && !patterns.symboladd.test(symbolid) && (symbolid != null)) {

                ns.ui.helpers.prompt({

                title: Granite.I18n.get("Invalid Number"),

                message: "Please Enter a valid 10 Digit Phone Number",

                actions: [{

                    id: "CANCEL",

                    text: "CANCEL",

                    className: "coral-Button"

                }],

            callback: function (actionId) {

                if (actionId === "CANCEL") {

                }

            }

        });

        }else{

                 $form.submit();

        }

    });

})(document, Granite.$, Granite.author);

As seen from the above code snippet, you can get the dialog element value using the name and apply the regex pattern test to validate the field and then with the Granite ui, you can prompt the validation to fail message as shown below:
