Blog Viewer Script

Script I made a few minutes ago to crawl blogposts in sequence. Run with Tampermonkey.

If you crawl onto a Link-Only blog the button will appear red. Privacy invasion!

 // ==UserScript==
// @name         Blog switcher
// @version      0.1
// @description  view blog posts sequentially
// @match        https://blog.spacehey.com/entry?id=*
// ==/UserScript==

(function() {

    'use strict';
    let postId = document.location.href.split("=")[1];
    let url = 'https://blog.spacehey.com/entry?id=';

    let nextPost = document.createElement("button");
    nextPost.id = "nextpostbutton";
    nextPost.innerText = "Next post";
    nextPost.style.width = "100%";
    nextPost.style.padding = "1rem";
    nextPost.style.fontFamily = "monospace";
    nextPost.style.backgroundColor = "black";
    nextPost.style.color = "white";
    nextPost.style.fontSize = "1.5rem";

    let goNext = function(){
        window.location.href = url + (parseInt(postId) + 1);
    }

    nextPost.addEventListener("click", goNext);
    for(var i of document.getElementsByTagName("h1")){
        if(i.innerText.includes("Page not found.")){
            goNext();
        }
    }

    for(var o of document.getElementsByClassName("error")){
        if(o.innerText.includes("Error: This is a private Blog Entry.")){
            goNext();
        }
    }

    for(var j of document.getElementsByClassName("category")){
        if(j.innerText.includes("Privacy: Link-only")){
            nextPost.style.backgroundColor = "red";
            nextPost.style.color = "black";
            nextPost.innerText = "Next Post (Currently on a Link-Only post)";
        }
    }

    document.getElementsByTagName("nav")[0].appendChild(nextPost);
})();
