DOMWatcher
A class for defining events that occur when a new element is added to the DOM.
Installation
npm i dug-domwatcher
Usage
import DOMWatcher from 'dug-domwatcher'
const watcher = new DOMWatcher()
Handling all new elements
watcher.addElementListener("all", el => {
// do what you want with the element
})
Handling elements only of a certain tagname
watcher.addElementListener("form", el => {
// only handles form elements
})
Custom filters
function isProductCard(el) {
return el.classList.contains("product-card")
}
watcher.addElementListener(isProductCard, el => {
// only handles elements with a class of "product-card"
})
On page load
By default, the elements wont be handled when the DOM first loads, but only when they are added to the DOM after the fact. You can force the handler to run on page load with true as an optional third argument.
watcher.addElementListener(tagNameOrFilter, handler, true)
