Vue.js and jQuery?

Question

Is it possible to use jQuery with Vue.js? I have a function this function that I want to use in my Vue component. The function basically slides the items in and out, but when I implemented using the <script> tags I got a list with all the items instead of the jQuery code working.

$("#slideshow > div:gt(0)").hide();

setInterval(function() {
$('#slideshow > div:first')
.fadeOut(0)
.next()
.fadeIn(1000)
.end()
.appendTo('#slideshow');
}, 5000);

How do I use that function in my code?

<template>
<div class="timer">
   <div class="title-block">
       <p class="title">MG de Jong</p>
       <p class="description">Sprint 1</p>
   </div>
   <div class="column">
     <div class="block">
         <p class="digit">{{ days | two_digits }}</p>
         <p class="text">Days</p>
     </div>
     <div class="block">
         <p class="digit">{{ hours | two_digits }}</p>
         <p class="text">Hours</p>
     </div>
     <div class="block">
         <p class="digit">{{ minutes | two_digits }}</p>
         <p class="text">Minutes</p>
     </div>
   </div>   
 </div>
</template>
<script>

export default {
props: {
   date: {
       type: Number
   },
},
data() {
   return {
       now: Math.trunc((new Date()).getTime() / 1000)
   }
},
mounted() {
   window.setInterval(() => {
       this.now = Math.trunc((new Date()).getTime() / 1000);
   },1000);


},
computed: {
   seconds() {
       return (this.modifiedDate - this.now) % 60;
   },
   minutes() {
       return Math.trunc((this.modifiedDate - this.now) / 60) % 60;
   },
   hours() {
       return Math.trunc((this.modifiedDate - this.now) / 60 / 60) % 24;
   },
   days() {
       return Math.trunc((this.modifiedDate - this.now) / 60 / 60 / 24);
   },
   modifiedDate: function(){
      return Math.trunc(Date.parse(this.date) / 1000)
   }
},
}
</script>

Answer 1

You can do that, but in most of cases, you don't need to.

If you are learning Vue, then try to think in Vue and just put jQuery away. In jQuery, you do things in imperative way; but now you should think in declarative way.
Do not manipulate the DOM by yourself directly. All the DOM manipulations should be handled by Vue, you just tell Vue what you want.

Vue provides Transition, your requirement can be done by this without jQuery at all. At first you may think it's not straightforward and want to solve it by jQuery, but once you get the point you will fall in love with it.

As some of he comments mention, you could use a mounted function. For more details you can see this article: https://vuejsdevelopers.com/2017/05/20/vue-js-safely-jquery-plugin/

Here is a basic example using cleave.js:

<template>
    <input />
</template>

<script>
/* eslint-disable no-new */
import Cleave from 'cleave.js'

export default {
  mounted () {
    new Cleave(this.$el, {
      date: true,
      datePattern: ['d', 'm', 'Y']
    })

    this.$el.oninput = (e) => {
      console.log('oninput the field', e.target.value)
      this.$emit('oninput', e.target.value)
    }
  }
}
</script>

<style>

</style>

App.vue

<template>
  <div id="app">
    <smart-cleave @oninput="logIt"></smart-cleave>
    <div>{{date}}</div>
  </div>
</template>

<script>

/* eslint-disable no-new */
import Cleave from 'cleave.js'
import SmartCleave from './components/SmartCleave'

new Cleave('#plain-input', {
  date: true,
  datePattern: ['d', 'm', 'Y']
})

export default {
  name: 'app',
  components: {
    SmartCleave
  },
  data () {
    return {
      date: ''
    }
  },
  methods: {
    logIt (val) {
      console.log('cahnged', val)
      this.date = val
    }
  }
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  /* text-align: center; */
  color: #2c3e50;
  margin-top: 60px;
}
</style>
