[AEM6.5] Limit Multifield in AEM6.5 and throw pop-up once reached Limit.

[tushaar_srivastava]

Hi Team,

I need one guidance here where I have to limit the multifield, upto certain value and once that value is reached then the [ADD] button will get disable and throw pop-up that "limit exceed"

Currently I am using JS where I am just restricting not to save the dialog, instead I have to show pop-us and disable the Add button if reached limit.

(function ($, $document) {
    "use strict";
 
    $.validator.register("foundation.validation.validator", {
        selector: "coral-multifield",
        validate: function(el) {
 
            var totalPanels = el["0"].items.getAll().length;
            var min;
            var max;
            if ($(el).data("min-item")){
                min = $(el).data("min-item");
                if(totalPanels < min) {
                    return "Minimum numbers of items required are: " + min;
                }
            }
            if ($(el).data("max-item")){
                max = $(el).data("max-item");
                if(totalPanels > max) {
                    return "Maximum numbers of items allowed are: " + max;
                }
            }
 
        }});
})($, $(document));

 in Addition to this :

We need to disable the add button and pop-up the limit reached message.

I tried, but it seems not working maybe because of Granite issue.

Any suggestion..

Thanks

Hi, 

For the button, you just need to identify a unique selector for this and then add the disabled property. Something like this:

$("button[coral-multifield-add]").prop("disabled", true);

For the popup, you could try something like this:

//Create the dialog
var dialog = new Coral.Dialog().set({
    id: 'myDialog',
    header: {
      innerHTML: 'This Dialog is Awesome'
    },
    content: {
      innerHTML: '<coral-checkbox id="agree">I Agree</coral-checkbox>'
    },
    footer: {
      innerHTML: '<button is="coral-button" variant="primary" coral-close>Ok</button>'
    }
  });
  document.body.appendChild(dialog);

//Show the dialog
dialog.show()

Here you have all the documentation about how to create a dialog: https://developer.adobe.com/experience-manager/reference-materials/6-5/coral-ui/coralui3/Coral.Dialo... 

Hope this helps
