Createelement with id?

Delving deeper: setAttribute method

Need to juggle with various attributes in addition to id? setAttribute is your trusty magic wand.

// Avada Kedavra! Oops, wrong spell.
const elem = document.createElement('div');
// This is it: Wingardium Leviosa!
elem.setAttribute('id', 'uniqueId');


setAttribute lets you glide through the standards set by DOM. It's a one-stop-shop for setting id, class, src, href, and almost any attribute you can think of, laying the groundwork for broad-spectrum DOM manipulation.

Helper function: Creating elements with attributes

For glory, code cleanliness, and reusability, setup a helper function to create elements and set attributes:

function createCustomElement(tag, attributes) {
  const element = document.createElement(tag);
  // Ready, set...attribute!
  for (let key in attributes) {
    element.setAttribute(key, attributes[key]);
  }
  return element;
}
// One function to rule them all:
const customDiv = createCustomElement('div', { id: 'uniqueId', class: 'myClass' });


With this superhero function, you can DRY the ocean (of your code) and enhance efficiency. Did anyone order a win-win?

With jQuery: ID assignment made elegant

The chic style of jQuery makes element creation with id (and other attributes) seem like a gala event:

// Fashion Div-ah
const $elem = $('<div/>', {
  id: 'uniqueId',
  class: 'myClass'
});


The elegance of jQuery syntax is way beyond vanilla JavaScript element creation and attribute assignment. Kind of like choosing a tux over jeans and a T-shirt.

Taming element ids: Common practices and pitfalls

Direct property access for IDs

Do you like getting straight to the point? Manipulating the id property directly is some straight-arrow stuff:

// One button to save them all
const btn = document.createElement('button');
btn.id = 'saveButton'; // Direct assignment. Boom.


But do keep in mind, consistency is the glue of life (and code). If you decide to play with setAttribute, stick with it and maintain some well-deserved readability and predictability.

Ensuring unique IDs

In case you're the flamboyant type, creating elements on-the-fly, keep your id values distinct and avoid duplicate id horror shows that cause script and CSS catastrophes.

let uniqueCounter = 0;
function createUniqueId(prefix) {
  // Count Dooku would approve
  return `${prefix}-${uniqueCounter++}`; 
}

const elem = document.createElement('canvas');
// The canvas of unique-nicity
elem.id = createUniqueId('canvas');


Finding your ID element

Once you've etched an element's id, you can artistically retrieve it using document.getElementById for further element manipulation or data-grubbing.

// Where's Waldo... I mean, saveButton
const savedButton = document.getElementById('saveButton');
// Perform actions with savedButton
