What is the difference between v-bind and v-model directives?

In Vue.js, v-bind and v-model are both directives used to handle data binding, but they serve different purposes.

  • v-bind Directive:
  • The v-bind directive is used to bind an attribute to an expression. It allows you to dynamically set the value of an HTML attribute based on a Vue.js expression.
  • It is commonly used to bind HTML attributes like src, href, class, style, etc.
  • Example:
<img v-bind:src="imageSource">
  • In this example, the src attribute of the <img> element is dynamically bound to the value of the imageSource property in the Vue instance.
  • v-model Directive:
  • The v-model directive is used for two-way data binding on form input elements (like input, textarea, and select). It creates a binding between the input field and a variable in the Vue instance.
  • It automatically updates the data property when the input value changes, and vice versa.
  • Example:
<input v-model="message">

In this example, the input element is bound to the message property. Any changes in the input field will update the message property, and changes to the message property will be reflected in the input field.
