Vue $data Object
Example
Using the $data object to change the color of a <div> element when it is clicked.
export default {
data() {
return {
color: 'lightgreen'
}
},
methods: {
changeColor() {
this.$data.color = 'pink';
}
}
}
See more examples below.
Definition and Usage
The $data object represents all the properties stored in the data part of the Vue instance.
In the example above, the color property is referred to with this.$data.color, but we can refer to the same property by just writing this.color and that is more common.
The $data object is used when we need to explicitly state that we are
referring to a property in the data part of the Vue instance.
We must use the $data object if we want to refer to a data property with a
name starting with "_" or "$", because in
such cases the this prefix alone will not work.

Example

>
<p>Click here</p>
</div>
