Vue Js Find Number from String: In Vue.js, you can find a number from a string using regular expressions. Regular expressions are patterns used to match character combinations in strings. You can create a regular expression to match numbers within a string using the pattern “/\d+/” which will match one or more digits in the string. Once you have the matched digits, you can convert them to a number using the parseInt() function. For example, if you have a string “I have 10 apples”, you can use the regular expression pattern to match the number “10” and convert it to a number using parseInt().

How can extract a number from a string in Vue Js?

This code is written in JavaScript using the Vue.js framework, which is a popular library for building user interfaces. Here is a step-by-step explanation of Vue Js find Number from String:

1. The code begins by defining a new Vue application using the Vue.createApp() method. This method creates a new instance of a Vue application, which we can then configure and mount to the DOM.
2. The data() method is used to define the initial state of our  Vue application. In this case, we define two data properties: myString and myNumbers. myString is initialized with a string value that describes a quantity of fruit. myNumbers is initialized as an empty array, which we will populate later with numeric values extracted from myString.
3. The mounted() method is a lifecycle hook that is called after the Vue instance has been mounted to the DOM. This is where we will put our code to extract numbers from the myString property. In this case, we use a regular expression to find all numeric values in the myString property and store them in the myNumbers array. If no numeric values are found, we set myNumbers to an empty array.

      <li v-for="(number, index) in myNumbers" :key="index">{{ number }}</li>
    </ul>
</div>
<script type="module">
		const app = Vue.createApp({
			data() {
				return {
					 myString: "I have 3 apples and 2 oranges.",
                     myNumbers: [],
				}
			},
		  mounted() {
              this.myNumbers = this.myString.match(/\d+/g) || [];
  },
     });
		app.mount('#app');
</script>
