Prevent form submitting when pressing enter from a text input , using Vue. Js

In Vue, to prevent form submission when pressing the Enter key in a text input, listen for keyboard events and call event.preventDefault() in the event handler. This prevents the default form submission behavior.

Here is a specific example:

HTML section:

html
<div id="app">
  <form @submit.prevent="handleSubmit">
    <input type="text" v-model="inputText" @keydown.enter.prevent="handleEnter">
    <button type="submit">Submit</button>
  </form>
</div>

Vue instance:

javascript
new Vue({
  el: '#app',
  data: {
    inputText: ''
  },
  methods: {
    handleEnter(event) {
      // Handle Enter key press logic, but do not submit form
      console.log("Enter was pressed, but form was not submitted.");
    },
    handleSubmit() {
      // Handle form submission logic
      console.log("Form submitted with:", this.inputText);
    }
  }
});

In this example, we use @keydown.enter.prevent on the <input> element. The .prevent modifier instructs Vue to call event.preventDefault() prior to executing the handleEnter method, preventing the default form submission behavior.

Additionally, we use @submit.prevent on the <form> element to ensure that in other scenarios (such as clicking the submit button), the default form submission behavior is prevented, and the handleSubmit method handles the submission. This approach provides better control, ensuring accidental submissions are avoided.

This approach enhances user experience because users may not want the form to submit solely due to pressing Enter, especially in forms with multiple input fields. By programmatically managing the Enter key behavior, we can provide a more intuitive interaction.
