better-el-ref v2.1.5

better-el-ref

A better way to reference HTML elements in JavaScript.

Reasoning

Consistently calling document.getElementById('id') is long and tedious and adds unnecessary length to code. Not to mention, the usage of document.querySelector('el') is notoriously slow and so by using the better-el-ref package, referencing HTML elements is easy and optimized. better-el-ref also provides a nice way to handle elements that do not exist or are empty which keeps code DRY, especially when using TypeScript.

Usage/Examples

<!-- Generic -->
<div id="element"></div>

<div class="element"></div>

<element></element>

<input name="element" />

<!-- Chaining -->
<div id="element-1">
  <p class="element-1"></p>
</div>

<input name="element-1">
  <elementT></elementT>
</input>

<div id="test">
  <test>
    <div id="test-1">
      <div id="test-2">
        <div id="test-3">
          <div id="test-4">
            <p class="test-class"></p>
          </div>
        </div>
      </div>
    </div>
  </test>
</div>

import getElement from 'better-el-ref'

getElement(element, name?)

/* Generic */
getElement('#element') // ID
getElement('.element') // Class
getElement('<element') // Tag
getElement('$element') // Name

/* Chaining */
getElement('#element-1 .element-1') // Nested class
getElement('$element-1 <elementT') // Nested tag
getElement('#test <test #test-1 #test-2 #test-3 #test-4 .test-class') // Nested class

/* Applying operations */
getElement('.test').innerHTML(`<img src="test" />`, 'a') // Append an `img` element to all elements with class of "test"
