How to solve the problem of blank space after the mobile Flickity carousel image slides to the last image?

Processing solution for the mobile Flickity carousel diagram sliding to the end of the blank page

When building a multi-attribute product display page, we usually need to dynamically display the corresponding product pictures according to the different attribute values ​​selected by the user. The PC side can be achieved by simply showing/hiding pictures, but when using Flickity carousel pictures on the mobile side, the blank page may appear after sliding to the last picture. This article will explain how to solve this problem so that the carousel image either stops sliding or loops back to the first image after sliding to the last image.

Suppose you have implemented the function of filtering and displaying corresponding images based on product attribute values, for example:

 _filterThumbnails: function(variant){
  // ... Filtering picture logic...
  $('[data-title]').hide(); // Hide all pictures// ... Show filtered pictures...
}

This code successfully filters and displays the picture. However, in the mobile Flickity, it can continue to slide after sliding to the last picture, resulting in a blank page. We need to adjust the Flickity configuration to solve this problem.

First, make sure Flickity is initialized correctly:

 $('.carousel').flickity({
  // Other configurations...
});

Solution 1: Stop sliding

To prevent the user from continuing to slide after the last image, set wrapAround option to false :

 $('.carousel').flickity({
  wrapAround: false,
  // Other configurations...
});

Solution 2: Loop play

If you want to automatically jump to the first picture after sliding to the last picture, set wrapAround option to true :

 $('.carousel').flickity({
  wrapAround: true,
  // Other configurations...
});

Key Steps: Refresh Flickity

In order to ensure that the carousel figure is updated correctly after the number of pictures changes, after the _filterThumbnails function is called, the Flickity needs to be reinitialized or reloadCells method needs to be called:

 _filterThumbnails: function(variant){
  // ... Filtering picture logic...
  $('.carousel').flickity('reloadCells');
}

Through the above adjustments, your mobile Flickity carousel image will stop or loop after sliding to the last image, effectively avoiding the problem of blank pages. Which option you choose depends on your design needs.
