    Quick selector

    Syntactic sugar for querySelector, querySelectorAll, & addEventListener allowing you to select, modify, and add event listeners for multiple elements in one line of code. Tiny package (<1KB GZIP). All Javascript events are supported.



    npm install quick-selector
    import qs from 'quick-selector'
    // or
    const qs = require('quick-selector')


    <script src=""></script>



    Selecting <div class="box"> elements, use any CSS selectors:

    const boxes = qs``

    This always returns an array of elements, not just one element.


    Adding and removing click event listener:

    const clickEvent = () => console.log('Clicked!')

    Removing event listener:



    Selecting only .element elements with the innerHTML value of 'Apples':

    const filtered = qs`.subtitle`.filter(element => element.innerHTML === 'Apples')

    Selecting only the first .subtitle element and adding a class (only(0) returns the first selected element, only(1) returns the second, etc.):

    qs`.subtitle`.only(0).set(element => element.classList.add = 'first-subtitle')

    Setting & getting

    Setting text colour of elements to red:

    qs`p`.set(el => = 'red')

    Getting an array containing the text content of each <p> element:

    const paragraphText = qs`p`.get(el => el.textContent)

    Modifying vanilla-selected elements

    Adding a blur event to a list of elements selected with querySelectorAll:

    const elementList = document.querySelectorAll('input')
    qs(elementList).blur(event => console.log(`${} lost focus`))


    Selecting and adding two event listeners

    // Quick selector
    qs``.input(ev => console.log( => = '')
    // Vanilla JS
    const emailInput = document.querySelectorAll('')
    for (const input of emailInput) {
      input.addEventListener('input', ev => {
      input.addEventListener('click', ev => { = ''

    Selecting, filtering selection, adding event listener, setting text colour

    const clickFunc = () => console.log("I've been clicked")
    // Quick selector
    qs`p.text`.filter(el => el.innerHTML.startsWith('Hello')).click(clickFunc).set(el => = 'red')
    // Vanilla
    const textBox = document.querySelectorAll('p.text')
    for (const box of textBox) {
      if (box.innerHTML.startsWith('Hello')) {
        box.addEventListener('click', clickFunc) = 'red'

    Adding a change event to every other textarea, from the second

    // Quick selector
    qs`textarea`.filter((el, index) => index % 2).change(ev => = 'Changed')
    // Vanilla
    const textareas = querySelectorAll('textarea')
    for (i = 0; i < textareas.length; i++) {
      if (i % 2) {
        textareas[i].addEventListener('change', ev => {
 = 'Changed'
    // Vanilla functional
    const textareas = Array.from(querySelectorAll('textarea'))
    textareas.filter((el, index) => index % 2).forEach(el => {
      el.addEventListener('change', ev => { = 'Changed'


    Query function

    Function Arguments Returns
    qs``, qs() String or Array. Input a CSS selector text string, or an array of HTML elements An array of HTML elements, with a special set of methods attached

    Query function methods

    Method Arguments Returns Notes
    .eventName() Function. A function to be added to the event. The templated array it was called upon. Every single event compatible with the user's browser will work. See Examples: .click, .mousedown, .blur.
    .remove None. Use in conjunction with an eventName() method. N/A Use .remove before an eventName() function, with the original function as the argument. Example:
    .set() Function. Pass a function that will be applied to a Array.forEach() method, iterating through the object. The templated array it was called upon. More info on Array.forEach() - MDN.
    .get() Function. Pass a function that will be applied to a method, iterating through the object. A new array containing the return values from the function. More info on - MDN.
    .filter() Function. Pass a function that will be applied to a Array.filter() method, iterating through the object. A templated array containing only the filtered elements. More info on Array.filter() - MDN.
    .only() Number. Pass a positive integer, corresponding to the index of the item in the quick-select array. A templated array containing only the selected element. .only(0) selects the first item on the page that matched the quick-select query, only(1) selects the second, etc.

    Note: All Array methods work, but the above methods all return a templated quick-select array (apart from .get()), and can be used with method chaining.
