Vue Js Extract All Numbers from User Input: To extract only numbers from an input in Vue.js, you can use a regular expression (regex) to remove any non-numeric characters from the input.In this tutorial, we will learn the method for extracting all numerical values from a user’s input.
What is the method for retrieving all numbers from user input in Vue.js?
In this particular example, the computed property “numericValue” takes a data property called “userInput” and uses a regular expression to remove any characters that are not numbers (i.e., anything that is not 0-9).
The regular expression used here is /[^0-9]/g, which is a pattern that matches any character that is not a number. The g flag at the end means that it should match all occurrences of the pattern in the string, not just the first one.
So, for example, if the user types in “12a3b4c5”, the computed property “numericValue” will return the string “12345”, with all the non-numeric characters removed.
Extracting All Numbers from User Input in Vue.js Example
<div id="app">
<input type="text" v-model="userInput">
<p>User Input: {{userInput}}</p>
<p>Extracted number: {{ numericValue }}</p>
</div>
<script type="module">
const app = Vue.createApp({
data() {
return {
userInput: ''
}
},
computed: {
numericValue() {
// Use regex to remove non-numeric characters
return this.userInput.replace(/[^0-9]/g, '');
}
}
});
app.mount('#app');
</script>
