V-Bind – Attribute Class Binding With Vue
Post Series: VueJS

V-Bind is a Vue kind of way to bind data to attributes or classes. This means that you can bind data to an attribute or event using v-bind or : for short. Doing this you can manipulate the display of a selector, content of an attribute and more.

Binding data to an Attribute

In this example we simply add a title attribute text to the title tag of a button with v-bind. You will see how easy it is to bind data to an attribute this way. By adding:


to the button we make the button title attribute accessible by Vue. To replace title by a text we want we add data object to the Vue instance and add it there:

data: {
 title: 'Now the title is being set through JavaScript'

When you now hover over the button you will see the text as defined in the data object. Here is the full example below:


As Vue is reactive we can change the data in the background and see that happen in the foreground. With the Vue Chrome extension installed open the console and add

$vm0.title = "Something else";

Vue Console

You will then see that the title has changed hovering over the button:

v-bind reactivity

And that is reactivity at work. And at the same time you see the binding in action.
