Exploring the DOM within the Vue component's Mounted lifecycle hook

Is there a way to access an element from within the mounted function in a VueJS instance?

I attempted to do so using the code below, but it returned an error stating that the element is undefined. However, upon checking the DOM, I can see that the element is present. Could this be due to the element not being rendered before the reference is made?

document.getElementsByName('transferDate_submit')[0].addEventListener("change",function(){});

Answer №1

When you call your Vue.js instance with $el, it returns an instance of HTMLElement. Make sure to refer to the official API documentation for more details.

For example:

let allLinks = this.$el.querySelectorAll('a')

If preferred, you can also use a unique identifier called a ref. Again, the API documentation provides further information.

An example using ref:

<!-- vm.$refs.p will reference the DOM node -->
<p ref="p">hello</p>

A great way to handle event binding in Vue.js is by using v-on:change or @change instead of directly manipulating the DOM element. By minimizing direct interaction with the DOM, Vue.js helps streamline your development process.
