A Tiny Scrap of JavaScript
Fifteen years ago, when "Web 2.0" was a thing, Ben Nolan's Behaviour.js enlightened me to the virtues of declarative programming. Developing for a web-browser really lends itself to this approach. Using "sheets" to target particular JavaScript code at selected DOM elements provides a way to separate, in a consistent way, the behaviorial aspects of a web-page. For a while I'd subscribed to his advice to use JQuery instead, and this was incredibly effective but always felt like I was cheating. Including JQuery in a web-page for a tiny bit of convenience was just heavy handed. Now, 15 years later, I've finally weened myself off of that crutch too. Below is a tiny scrap of JavaScript that leverages the native JavaScript Document.querySelectorAll() function...
function attachBehaviors(behaviors, context = document) {
Object.entries(behaviors).forEach(([selector, behavior], index) => {
if (typeof behavior === 'function') {
context.querySelectorAll(selector).forEach(elm => {
behavior.call(this, index, elm);
});
}
});
}
export {attachBehaviors};
With this function available, now pass a "sheet"...
attachBehaviors({
'a.externallink': function(idx, elm) {
elm.addEventListener('click', function(evt) {
evt.preventDefault();
window.open(evt.target.href);
});
},
'form#uploadForm': function(idx, elm) {
elm.addEventListener('submit', function(evt) {
evt.preventDefault();
processFiles();
});
}
});
