<button :disabled="isButtonDisabled”>...

If isActive is truthy, the class ‘active’ will appear:

<div :class="{ active: isActive }">...

Style color set to value of activeColor:

<div :style="{ color: activeColor }">
Vuejs Binding3

Toggles the display: none CSS property:

<p v-show="showProductDetails">

Passing arguments to a computed binding:

  <ProductComponent :cost="product_type('product_2')"></ProductComponent>

  import ProductComponent from @/components/ProductComponent
  export default {
    components: { ProductComponent },
    data() {
      return {
        products: {
          product_1: '100',
          product_2: '200',
          product_3: '300'
    computed: {
      product_type() {
        // Argument passed to arrow function, NOT computed function declaration.
        return (product_id) => { // Arrow function to allow 'this' instance to be accessible.
          return this.products[product_id]  // Square bracket notation for 'any' type variable
Vuejs List Rendering

Basic array loop

<li v-for="item in items" :key="">
  {{ item }}

Loop with access to index

<li v-for="(item, index) in items">...</li>

Baisc object loop

<li v-for="value in object">...</li>
<li v-for="(value, index) in object">...</li>
<li v-for="(value, name, index) in object">...</li>

Loop using component instead of html native element e.g. div, li

<cart-product v-for="item in products" :product="item" :key="">
Vuejs Actions/Events
<button v-on:click="addToCart">...</button> // Fullhand
<button @click="addToCart">...</button> // Shorthand

Arguments can be passed:

<button @click="addToCart(product)">...</button>

To prevent default behaviour (e.g. page reload):

<form @submit.prevent="addProduct">...</form>

Only trigger once:

<img @mouseover.once="showImage">
.stop // Stop all event propagation
.self // Only trigger if is element itself

Keyboard entry example:

<input @keyup.enter="submit">

Call onCopy when control-c is pressed:

<input @keyup.ctrl.c="onCopy">
