Anodum

Another Document utils library

Overview

How to Install

Using NPM

In order to use Anodum with NPM simply call:

npm install --save anodum

In Browser

In order to use Anodum directly in browser simply download this repository and copy dist/anodum.js into your project. Next, include it on your .html page:

<script src="path/to/your/js/anodum.js"></script>

Get Started

You are able to use Anodum as the importable npm package or directly in browser.

In Node.js

import { isNode } from "anodum";

const result = isNode(document); // result => true

In Browser

<script>
var result = Anodum.isNode(document); // result => true
</script>

Constants

Anodum exports a small set of predefined constants eg.

domParser
xmlSerializer
nodeTypes

You are able to use them as well as any of API methods bellow.

API

copyElementAttributes(element, targetElement)

Copies all attributes of element into targetElement. Existing targetElement attributes will be overwritten.

import { copyElementAttributes } from "anodum"; // or anodum.copyElementAttributes if using in browser

const sourceNode = document.createElement('div');
const targetNode = document.createElement('div');

sourceNode.setAttribute('class', 'container');
sourceNode.setAttribute('id', 'my-div');

copyElementAttributes(sourceNode, targetNode);

// tragetNode.getAttribute('id') => 'my-div'
// tragetNode.getAttribute('class') => 'container'

getClosestScrollableElement(rootNode, useClientHeight)

Get the closest element that has a scrollable area. If useClientHeight is set to false, function doesn't compare element's scrollHeight and clientHeight. Default value is true.

import { getClosestScrollableElement } from "anodum"; // or anodum.getClosestScrollableElement if using in browser

const element = document.createElement('div');

const scrollableElement = getClosestScrollableElement(element); // scrollableElement => document

getElementHeight(element, includeMargins)

Calculates element height. If includeMargins is set to true the final value will include top and bottom margins

import { getElementHeight } from "anodum"; // or anodum.getElementHeight if using in browser

const element = document.createElement('div');

document.body.appendChild(element);
element.style.height = '40px';
element.style.marginTop = '20px';
element.style.marginBottom = '20px';

const height = getElementHeight(element); // height => 80px

getNodeByTreePath(rootNode, path)

Looks for an element inside rootNode by related tree path path.

import { getNodeByTreePath } from "anodum"; // or anodum.getNodeByTreePath if using in browser

const path = [0, 1, 1, 0];
const rootNode = document.createElement('div');
rootNode.innerHTML = 'text<div><h1></h1><p>target</p></div>';

const node = getNodeByTreePath(rootNode, path);

// node.nodeType => 3 (#text)
// node.textContent => target

getTreePathOfNode(node, rootNode)

Calculates a tree path of target node.

rootNode - is an optional parameter that sets the root element relative to which the path is calculated

import { getTreePathOfNode } from "anodum"; // or anodum.getTreePathOfNode if using in browser

const element = document.createElement('div');
element.innerHTML = 'text<p>inner text</p>';
