Panduan Membuat TOC Pada Viomagz
1. Langkah Awal
Kode JavaScript
Silahkan buka pengeditan HTML Blogger di Edit HTML.
Lalu cari kode </body>
Letakkan JavaScript Table of Contents berikut ini di atasnya:
<script>
//<![CDATA[
// var contentContainer = document.querySelectorAll(".post-body")[0].id = "toc-container";
var contentContainer = document.querySelectorAll(".post-body")[0];
const dataTracking = contentContainer.setAttribute("data-tracking-container", "true");
var headings = contentContainer.querySelectorAll("h1,h2,h3,h4,h5,h6");
var showtoc = contentContainer.querySelectorAll(".post-body h1,.post-body h2,.post-body h3,.post-body h4,.post-body h5,.post-body h6");
if (headings.length > 3) {
for (i = 0; i <= showtoc.length - 1; i++) {
var tocauto = showtoc[i];
tocauto.insertAdjacentHTML('beforebegin','<div class="toc-auto"><input id="toc-sh" type="checkbox"><label class="toc-title" for="toc-sh">Table of Contents</label><div class="toc" id="toc"></div></div>');
tocatr = document.querySelectorAll(".toc-auto")[0];
tocatr.setAttribute('data-tracking-container', 'true');
var toptoc = document.querySelectorAll(".toc-auto");
[].filter.call(toptoc, function(tocselection) {
return ![].some.call(tocselection.attributes, function(attr) {
return /^data-tracking-container/i.test(attr.name);
});
}).forEach(function(tocselection) {
tocselection.parentNode.removeChild(tocselection);
});};}
class TableOfContents {
constructor({ from, to }) {
this.fromElement = from;
this.toElement = to;
// Get all the ordered headings.
this.headingElements = this.fromElement.querySelectorAll("h1, h2, h3, h4, h5, h6");
this.tocElement = document.createElement("div");
}
getMostImportantHeadingLevel() {
let mostImportantHeadingLevel = 6;
for (let i = 0; i < this.headingElements.length; i++) {
let headingLevel = TableOfContents.getHeadingLevel(this.headingElements[i]);
mostImportantHeadingLevel = (headingLevel < mostImportantHeadingLevel) ?
headingLevel : mostImportantHeadingLevel;
}
return mostImportantHeadingLevel;
}
static generateId(headingElement) {
return headingElement.textContent.toLowerCase().replace(/ /g,"_").replace(/\//g,"_").replace(/</g,"").replace(/>/g,"").replace(/&/g,"").replace(/&nbsp;/g,"").replace(/ /g,"").replace(/\xA0/g,"").replace(/[\n\r\f]+/g, "").replace(/[.,\#!$%\^&\*;:{}=\-@`~()<>?"'“+”]/g,"");
}
static getHeadingLevel(headingElement) {
switch (headingElement.tagName.toLowerCase()) {
case "h1": return 1;
case "h2": return 2;
case "h3": return 3;
case "h4": return 4;
case "h5": return 5;
case "h6": return 6;
default: return 1;
}
}
generateToc() {
let currentLevel = this.getMostImportantHeadingLevel() - 1,
currentElement = this.tocElement;
for (let i = 0; i < this.headingElements.length; i++) {
let headingElement = this.headingElements[i],
headingLevel = TableOfContents.getHeadingLevel(headingElement),
headingLevelDifference = headingLevel - currentLevel,
linkElement = document.createElement("a");
if (!headingElement.id) {
headingElement.id = TableOfContents.generateId(headingElement);
}
linkElement.href = `#${headingElement.id}`;
linkElement.textContent = headingElement.textContent;
if (headingLevelDifference > 0) {
for (let j = 0; j < headingLevelDifference; j++) {
let listElement = document.createElement("ul"),
listItemElement = document.createElement("li");
listElement.appendChild(listItemElement);
currentElement.appendChild(listElement);
currentElement = listItemElement;
}
currentElement.appendChild(linkElement);
} else {
for (let j = 0; j < -headingLevelDifference; j++) {
currentElement = currentElement.parentNode.parentNode;
}
let listItemElement = document.createElement("li");
listItemElement.appendChild(linkElement);
currentElement.parentNode.appendChild(listItemElement);
currentElement = listItemElement;
}
currentLevel = headingLevel;
}
this.toElement.appendChild(this.tocElement.firstChild);
}
}
document.addEventListener("DOMContentLoaded", () =>
new TableOfContents({
from: document.querySelector(".post-body"),
to: document.querySelector(".toc")
}).generateToc()
);
//]]>
</script>
2. Langkah Kedua
Kode CSS
Tambahkan kode CSS berikut di atas </style> atau ]]></b:skin> untuk mengatur tampilan Table of Content. Termasuk mengatur Table of Contents agar bisa show-hide.
html {
scroll-behavior: smooth;
}
/* TOC style bungfrangki.com */
.toc-auto {
display: table;
position: relative;
border-radius: 3px;
background-color: var(--widget-bg,#f6f9fc);
padding: 1rem 1rem.85rem;
margin: 0 0 1.5rem;
}
.toc-auto a {
transition: .3s ease-in;
text-decoration:none;
}
.toc-auto a:hover, .toc-auto .current {
text-decoration: underline !important;
color: var(--a-hover,#fe8f04);
}
.toc-auto input[type="checkbox"] {
display: none;
}
.toc-title {
font-weight: 700 !important;
margin-top: 5px;
}
.toc-title:after {
content: '-';
background-color: var(--text-secondary,#a6e6e5);
border-radius: 3px;
clear: both;
float: right;
margin-left: 1rem;
cursor: pointer;
font-weight: 400 !important;
display: flex;
justify-content: center;
align-items: center;
width: 25px;
height: 25px;
transition: .3s ease-in;
}
.toc-title:after:hover {
background-color: var(--main-color,#028271);
color: #fff;
}
.toc-auto .toc {
max-height: 100%;
max-width: 500px;
opacity: 1;
overflow: hidden;
transition: max-height .1s ease,max-width 0s ease,margin-top .3s linear,opacity .3s linear,visibility .3s linear;
visibility: visible;
}
.toc-auto ul li,ol li {
margin-bottom: 0 !important;
}
#toc-sh:checked~.toc-title:after {
content: '+';
}
#toc-sh:checked ~ .toc {
margin-top: 0;
max-height: 0;
max-width: 0;
opacity: 0;
transition: max-height 0s ease,max-width 0s ease,margin-top .3s linear,opacity .3s linear,visibility .3s linear;
visibility: hidden;
}
3. Langkah Ketiga
Setelah itu, silahkan simpan perubahan pada template Blogspot dengan klik ikon Simpan Tema.
4. Langkah Ke Empat
Setelan Table of Contents Otomatis di Blogger
Sedikit saya jelaskan tentang setelan Table of Contents otomatis ini agar sesuai dengan keinginan masing-masing, yaitu sebagai berikut:
Secara default Table of Contents ini akan otomatis muncul bila pada postingan terdapat lebih dari 3 Tag Heading.
Bila ingin mengubahnya dan ingin menampilkan Table of Content pada jumlah heading sesuai keinginan, silahkan ganti angka 3 pada kode if (headings.length > 3) dengan angka lainnya.
Table of Contents akan muncul di atas Heading paling atas (bukan judul artikel). Terlepas dari apapun jenis Tag Headingnya. Entah itu <h1>, <h2>, <h3>, <h4>, <h5>, ataupun <h6>.
Apabila ingin menampilkannya di bawah Tag Heading, ubah beforebegin menjadi afterend pada JavaScript.
Table of Contents hanya akan tampil bila template blogspot memiliki tag class .post-body. Apabila tag tersebut tidak ada di template, Anda boleh menggantinya dengan selector lain pada kode: var contentContainer = document.querySelectorAll(".post-body")
