How to convert string to array in VueJS?

Hi Friends 👋,

Welcome To SortoutCode! ❤️

To convert string to array in VueJS. Sometimes we need to convert the string to an array. There are different ways to convert the string to an array. In this We are going to use the split(), Array.from(), and Array.prototype.push() methods to convert the string to an array.

Short solution

parentComp.vue

var Arry = "Monday,Tuesday,Sunday"; //string

// using the split() method
arrA = Arry.split(",");

console.log(arrA); // ['Monday',' Tuesday','Sunday']

// using the Array.from() method
arrB = Array.from(this.str.split(","));

console.log(arrB); // ['Monday',' Tuesday','Sunday']

let newArray = [];
let arrC = "";
for (let i = 0; i < Arry.length; i++) {
  if (Arry[i] !== ",") {
    temp += Arry[i];
  } else {
    newArray.push(temp.trim());
    temp = "";
  }
}
if (temp. length) {
  newArray.push(temp.trim());
}

console.log(newArray);
); // ['Monday',' Tuesday','Sunday']

This article will guide you to How do I convert string to array in vueJS

Setup the Vue.js

First, we have to install the Vue project, I had installed the vueJS in my system. If you haven’t installed or have any problem with installation you can follow this article, it will show you step by step process of installation.

How to Install the VueJS project?

Create FirstComponent.vue and import it into App.js

Create the new component in the src/components/ components folder. The component name is FirstComponent.vue and imported into the App.js file:

App.js

<template>
  <FirstComp />
</template>

<script>
import FirstComp from "./components/FirstComp.vue";
export default {
  name: "App",
  components: {
    FirstComp: FirstComp,
  },
};
</script>

Convert string to array using split() method

To convert the string to an array in vuejs. We are going to define the long string logString in the data property and defined the newArray empty array data property. And we are going to use the split() method. This method will convert the string into an array. Let’s take a short example to better understand.

FirstComp.vue

<template>
  <div class="hello"></div>
  <h1>Welcome to sortoutcode.com</h1>
  <p>Long String : {{ logString }}</p>
  <p v-if="newArray">Array : {{ newArray }}</p>

  <button @click="convertMethodA">Convert</button>
</template>

<script>
export default {
  name: "FirstComp",
  data() {
    return {
      logString: "magzine, sortout, google, youtube",
      newArray: [],
    };
  },
  methods: {
    convertMethodA() {
      this.newArray = this.logString.split(", "); //[ "magzine", "sortout", "google", "youtube" ]
    },
  },
};
</script>

For now, let’s check the output.

Convert string to an array using Array.from() method

To convert the string to an array in vuejs. We are going to define the long string logString in the data property and defined the newAArray empty array data property. And we are going to convert this string to an array using the Array.from() method. This method will convert the string into an array. Let’s take a short example to better understand.

FirstComp.vue

<template>
  <div class="hello"></div>
  <h1>Welcome to sortoutcode.com</h1>
  <p>Long String : {{ logString }}</p>
  <p v-if="newArray">Array : {{ newArray }}</p>

  <button @click="convertMethodB">Convert</button>
</template>

<script>
export default {
  name: "FirstComp",
  data() {
    return {
      logString: "magzine, sortout, google, youtube",
      newArray: [],
    };
  },
  methods: {
    convertMethodB() {
      this.newArray = Array.from(this.logString.split(", ")); //[ "magazine", "sortout", "google", "youtube" ]
    },
  },
};
</script>

Convert string to an array using Array.prototype.push() method

To convert the string to an array in vuejs. We are going to define the long string logString in the data property and defined the newAArray empty array data property. And we are going to convert this string to an array using the Array.prototype.push() method. This method will convert the string into an array. Let’s take a short example to better understand.

FirstComp.vue

  <h1>Welcome to sortoutcode.com</h1>
  <p>Long String : {{ logString }}</p>
  <p v-if="newArray">Array : {{ newArray }}</p>

  <button @click="convertMethodC">Convert</button>
</template>

<script>
export default {
  name: "FirstComp",
  data() {
    return {
      logString: "magzine, sortout, google, youtube",
      newArray: [],
    };
  },
  methods: {
   convertMethodC() {
      let temp = "";
      for (let i = 0; i < this.logString.length; i++) {
        if (this.logString[i] !== ",") {
          temp += this.logString[i];
        } else {
          this.newArray.push(temp.trim());
          temp = "";
        }
