Tumblr get Like Button status with Infinite Scroll

917 views Asked by At

I would like to request the Like Button status of each post (by ID) that is appended by Infinite Scroll.

<li class="post text" id="{PostID}">

The Tumblr Documentation provides this method of checking the status of a Like Button for individual posts:

Tumblr.LikeButton.get_status_by_page(n)
Description: Call this function after requesting a new page of Posts. Takes the page number that was just loaded as an integer.

Finally, here is the Infinite Scroll script (Proto.jp modified by Cody Sherman):

$(document).ready(function() {
var tumblrAutoPager = {
    url: "http://proto.jp/",
    ver: "0.1.7",

    pp: null,
    ppId: "",
    LN: location.hostname,
    init: function() {
        if ($("autopagerize_icon") || navigator.userAgent.indexOf('iPhone') != -1) return;
        var tAP = tumblrAutoPager;
        var p = 1;
        var lh = location.href;
        var lhp = lh.lastIndexOf("/page/");
        var lht = lh.lastIndexOf("/tagged/");
        if (lhp != -1) {
            p = parseInt(lh.slice(lhp + 6));
            tAP.LN = lh.slice(7, lhp);
        } else if (lht != -1) {
            tAP.LN = lh.slice(7);
            if (tAP.LN.slice(tAP.LN.length - 1) == "/") tAP.LN = tAP.LN.slice(0, tAP.LN.length - 1);

});

Any insight is greatly appreciated. Thank you!

This seemed to do the trick!

            function addNextPage(oj) {
            if (oj.status == 404) {
                tAP.remainFlg = false;
                return;
            }
            var d = document.createElement("div");
            d.innerHTML = oj.responseText;
            var posts = tAP.gP(d.getElementsByTagName("*"));
            if (posts.length < 2) {
                tAP.rF = false;
                return;
            }
            d = document.createElement("div");
            d.className = "tumblrAutoPager_page_info";
            tAP.pp.appendChild(d);
            for (var i = 0; i < posts.length; i++) {
                tAP.pp.appendChild(posts[i]);
            }
            var footer = $("footer");
            footer ? footer.parentNode.appendChild(footer) : null;
            tAP.rF = true;

            //Get Like Button status of newly appended page
            Tumblr.LikeButton.get_status_by_page(p);
        }
