Tumblr like button not working after infinite scroll ajax recall

问题

There are a few similar posts but they are quite out of date and Tumblr has updated the like part of the API not too long ago as far as I'm aware.

Creating a like button is as simple as {LikeButton}

and this works great, but after the ajax recalls to get more posts from what would be the next page, the like button no longer works.

I have had a look at the documentation and it states that I need to implement one of the following, I was wondering if anyone could point me in the right direction? I've been trying to get this to work for hours.

I made up an example blog if this helps contribute to answering, the javascript can do the mass amount of the implementing of new images.

If you need anymore info, i'll happily edit this and add what's required, thank you!

Overview

Adapted from my previous answer here: Using Tumblr Like Button with Infinite Scroll

Tumblr states we need to call one of two functions to get the Like Status. I would suggest the following:

Function: Tumblr.LikeButton.get_status_by_post_ids([n,n,n]) Description: Request Like status for individual posts. Takes an array of post IDs

Once the ajax request is successful , we should have a data object (containing new posts, etc).

We need to create an array of postIDs, which is an array containing an ID / number for each post in the data object. Easiest way to add the the post id is to use the theme variable {PostID}.

Example

HTML

<article class="post" id="{PostID}">...</article>

jQuery Post IDs Array

var $newPosts   = $(data).find('.post');
var $newPostIDs = $newPosts.map(function () {
    return $(this).attr('id');
}).get();

Tumblr.LikeButton

Tumblr.LikeButton.get_status_by_post_ids($newPostIDs);

Hints

Create the array and call Tumblr.LikeButton once the ajax request is successful and in a place where you run other functions for the new Posts. This can also be done with pure javascript as using: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map
