How To Get Element by ID in Vue

This quick vue tutorial helps to get elements by id in vue.js. There are a number of ways to get elemnt by id in vue.js. Sometimes, we need to access and manipulate specific elements directly, and we need id of that element to apply the operation.

Vue

Vue.js is a JavaScript framework that helps developers build user interfaces for web applications. It adopts a component-based architecture, allowing developers to create modular and reusable components. It has inbuilt features like data binding and DOM updates.

Native JavaScript Approach

Vue.js is built on JavaScript and we can take leverage of javaScript native features like method: getElementById(). Let’s take a simple example of this:

updateLable() {
const myElement = document.getElementById('myElementId');
console.log(myElement);
}

in the above example, we retrieve the element with the specified ID using getElementById() and provide 'myElementId' as the parameter.

Refs in Vue.js

Vue.js provides a feature called refs, Which are used to reference or access a child component or DOM element from its parent component. This method helps to interact with child components or DOM elements directly.

<template>
  <div>
    <div ref="myElement"></div>
  </div>
</template>

<script>
export default {
  mounted() {
    // Accessing an element using refs
    const myElement = this.$refs.myElement;
    console.log(myElement);
  }
}
</script>

In the above, We have used the ref attribute to create a reference to the myElement div. The reference can then be accessed using this.$refs within the parent component’s

Vue.js Directives: Get an element by id

Vue.js directives provide a powerful way to interact with the DOM. The v-el directive can be used to access elements by ID directly. Here’s an example:

<template>
  <div>
    <div v-el:myElementId></div>
  </div>
</template>

in the above code, We have used v-el directive to create a reference to the element with the specified ID. The reference is then accessible through this.$els in the component’s methods.

Conclusion

We have discussed different approaches to get elements by id in vue.js. You can use javascript native, vue ref, and vue directives. Each method has its advantages and disadvantages. You can choose one of them based on your requirements for your project.
