How can I integrate this component in my vue.js?

Question

I am trying to add this component in my App but as vue component but for some reason, the page is not loading. Source of component: https://codepen.io/jessicachou/details/bjaZmY

I am getting the following warnings:

• Unresolved function or method isNumeric() (line 35)
• Unused parameter e (line 32)

-Argument type string is not assignable to parameter type object | undefined Type string is not assignable to type object (32)

<template>
  <div class="content center">

Answer 1

One way would be like following snippet:

 new Vue({ el: '#demo', data() { return { years: { small: 40, medium: 45, big: 49 }, year: 5 } }, methods: { calcYears() { this.years.small = (this.year * 4) + 20 this.years.medium = (this.year * 6) + 15 this.years.big = (this.year * 9) + 4 } } })

 .content { background-color: #caefec; font-family: Arial,sans-serif; padding: 20px; max-width: 800px; margin: auto; }.center { text-align: center; } h2 { color: #03363d; font-size: 32px; line-height: 1.2; }.num-age { appearance: none; -webkit-appearance: none; border-radius: 12px; background-color: #fafafa; box-shadow: 0 14px 14px 0 rgba(23,23,23,0.07); border: solid 2px #f3f3f3; color: #03363d; font: 28px/1.16 Arial,sans-serif; outline: 0; margin: 10px 0; max-width: 200px; padding: 10px; }.num-result { display: inline-block; width: 32%; vertical-align: top; }.disclaimer { color: #03363d; font-size: 14px; }.image-dog { max-width: 100%; max-height: 100px; }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script> <div id="demo"> <div class="content center"> <h2>How old is your dog in human years?</h2> <div class="input-container"> <input type="number"class="num-age center" id="input" placeholder="5" v-model="year" @keyup="calcYears" @change="calcYears"> </div> <div class="calc-results"> <div class="num-result center"> <h2 class="num-totals total-small-dog" data-default="total-small-dog">{{ years.small }}</h2> <img class="image-dog" src="..." alt=".."/> <h3 class="description-small-dog">Small dog</h3> </div> <div class="num-result center"> <h2 class="num-totals total-medium-dog" data-default="45" >{{ years.medium }}</h2> <img class="image-dog" src="..." alt="..."/> <h3 class="description-medium-dog">Medium dog</h3> </div> <div class="num-result center"> <h2 class="num-totals total-big-dog" data-default="49">{{ years.big }}</h2> <img class="image-dog" src="..." alt=".."/> <h3 class="description-big-dog">Big dog</h3> </div> </div> <p class="disclaimer">*No dogs were harmed in the creation of this calculator.</p> </div> </div>

With plain JS:

 <style>.content { background-color: #caefec; font-family: Arial,sans-serif; padding: 20px; max-width: 800px; margin: auto; }.center { text-align: center; } h2 { color: #03363d; font-size: 32px; line-height: 1.2; }.num-age { appearance: none; -webkit-appearance: none; border-radius: 12px; background-color: #fafafa; box-shadow: 0 14px 14px 0 rgba(23,23,23,0.07); border: solid 2px #f3f3f3; color: #03363d; font: 28px/1.16 Arial,sans-serif; outline: 0; margin: 10px 0; max-width: 200px; padding: 10px; }.num-result { display: inline-block; width: 32%; vertical-align: top; }.disclaimer { color: #03363d; font-size: 14px; }.image-dog { max-width: 100%; max-height: 100px; } </style> <div class="content center"> <h2>How old is your dog in human years?</h2> <div class="input-container"> <input class="num-age center" id="input" placeholder="5"> </div> <div class="calc-results"> <div class="num-result center"> <h2 class="num-totals total-small-dog" data-default="total-small-dog">40</h2> <img class="image-dog" src="..." alt=".."/> <h3 class="description-small-dog">Small dog</h3> </div> <div class="num-result center"> <h2 class="num-totals total-medium-dog" data-default="45">45</h2> <img class="image-dog" src="..." alt="..."/> <h3 class="description-medium-dog">Medium dog</h3> </div> <div class="num-result center"> <h2 class="num-totals total-big-dog" data-default="49">49</h2> <img class="image-dog" src="..." alt=".."/> <h3 class="description-big-dog">Big dog</h3> </div> </div> <p class="disclaimer">*No dogs were harmed in the creation of this calculator.</p> </div> <script> document.querySelector("#input").addEventListener('keyup', (event) => { let num, smallAge, mediumAge, bigAge num = event.target.value if (.isNaN(num)) { smallAge = (num * 4) + 20 mediumAge = (num * 6) + 15 bigAge = (num * 9) + 4 document.querySelector(".total-small-dog").innerText = smallAge document.querySelector(".total-medium-dog").innerText = mediumAge document.querySelector(".total-big-dog").innerText = bigAge } }) </script>
