How to call native HTML methods in Vue

Vue is a modern JavaScript framework designed for developing single-page applications. It provides an efficient and easy-to-maintain way to build web applications through two-way data binding and componentized architecture. However, in Vue development, sometimes we need to call native HTML methods to implement some special functions. This article will introduce how to call native HTML methods in Vue.

Calling native HTML methods in Vue

Vue.js implements two-way binding of Vue data through virtual DOM. But sometimes we need to manipulate data directly in the actual DOM. At this time, we need to use Vue's life cycle functions and hook functions.

Calling method

In the mounted hook function of the Vue life cycle, you can get the actual DOM. We can access it using the $el property. Once the actual DOM is obtained, we can directly call the HTML native API or jQuery API to implement some special functions.

For example, if we want to call the HTML native alert method in Vue, we can do this:

mounted () {
  this.$nextTick(function () {
    alert('Hello world!');
  })
}

In this example, we use the $nextTick method of Vue.js, To ensure that the alert() method is executed after DOM rendering is completed.

Call method through jQuery

If we want to operate the actual DOM through jQuery in Vue, we need to introduce jQuery in the mounted hook function and call the jQuery API there.

For example, to use jQuery to set the attributes of a DOM element in Vue, we can do this:

mounted () {
  this.$nextTick(function () {
    $('h1').attr('title', 'Hello World');
  })
}

In this example, we use jQuery to set the title attribute of the h1 element.

Finally

Although Vue.js itself provides many convenient methods and instructions, in some cases, we still need to implement some special functions through native HTML methods or jQuery. Through the above method, we can easily call native HTML methods or jQuery API in Vue to achieve more flexible and efficient development.
