Vue Js input allow only 10 digt number:In Vue.js, the “v-model” directive can be used to create two-way data binding between a form input element and a data property. To restrict the input to only 10 digit numbers, we can use the “v-on:input” directive to listen for input events and update the data property accordingly. Within the event handler, we can use JavaScript’s string methods to extract the first 10 digits of the entered value and assign it to the data property. For example, we can use the “substring” method to extract the first 10 characters of the entered value, or use regular expressions to remove any non-digit characters from the entered value before assigning it to the data property. This will ensure that the input field only accepts 10 digit numbers.

How can I restrict a text field in Vue.js to only allow the input of a maximum of 10 digits/numbers?

The code you provided is a Vue.js component that allows users to input a phone number and limits it to 10 digits. Here’s a breakdown of how it works:

1. The input element has a v-model directive that binds the input value to the phoneNumber data property in the Vue instance. This means that any changes made to the input field will update the phoneNumber value.
2. The input element also has a v-on:input directive that binds the limitPhoneNumber method to the input event. This means that whenever the user types or deletes something in the input field, the limitPhoneNumber method will be called.
3. The data function returns an object with a phoneNumber property initialized to “1234567890”. This sets the initial value of the input field to “1234567890”.
4. The limitPhoneNumber method removes any non-digit characters from the phoneNumber value using a regular expression (/\D/g). This ensures that only digits are allowed in the phone number.
5. The method then checks if the length of the phoneNumber value is greater than 10. If it is, it uses the substring() method to truncate the phoneNumber value to 10 digits.

So overall, this code limits the phone number input to 10 digits and removes any non-digit characters.

Vue Js Text field allow only 10 digt number Example

<div id="app">
        <input v-model="phoneNumber" v-on:input="limitPhoneNumber" />
    </div>
    <script type="module">
        const app = new Vue({
            el: "#app",
            data() {
                return {
                    phoneNumber: "1234567890"
                };
            },
            methods: {
                limitPhoneNumber() {
                    // Remove any non-digit characters from the phone number
                    this.phoneNumber = this.phoneNumber.replace(/\D/g, "");

                    // Limit the phone number to 10 digits
                    if (this.phoneNumber.length > 10) {
                        this.phoneNumber = this.phoneNumber.substring(0, 10);
                    }
                }
            }
        });
    </script>
