The NextTick Function In Vue

The nextTick function in Vue – onlinecode

In this post, we will give you information about The nextTick function in Vue – onlinecode. Here we will give you detail about The nextTick function in Vue – onlinecode And how to use it also give you a demo for it if it is necessary.

The nextTick() function allows you to execute code after you have changed some data and Vue has updated the page to reflect your changes.
Pass a callback to nextTick() and Vue will execute the callback immediately after updating the DOM.

const app = new Vue({
  data: () => ({ text: 'First' }),
  template: '<h1>{{text}}</h1>',
  mounted: function() {
    this.text = 'Second';

    // Prints 'First', because Vue hasn't updated the DOM yet
    console.log(this.$el.textContent);

    this.$nextTick(() => {
      // Prints 'Second', because Vue has updated the DOM
      console.log(this.$el.textContent);
    });
  }
});

Alternatively, you can use Vue.nextTick(), which is the same thing as this.$nextTick().

const app = new Vue({
  data: () => ({ text: 'First' }),
  template: '<h1>{{text}}</h1>',
  mounted: function() {
    this.text = 'Second';

    // Prints 'First', because Vue hasn't updated the DOM yet
    console.log(this.$el.textContent);

    Vue.nextTick(() => {
      // Prints 'Second', because Vue has updated the DOM
      console.log(this.$el.textContent);
    });
  }
});

With Promises

One neat advantage of Vue’s nextTick() over the browser’s setTimeout() function is that nextTick() returns a promise, so you can await on it.

const app = new Vue({
  data: () => ({ text: 'First' }),
  template: '<h1>{{text}}</h1>',
  mounted: async function() {
    this.text = 'Second';

    // Prints 'First', because Vue hasn't updated the DOM yet
    console.log(this.$el.textContent);

    await Vue.nextTick();
    // Prints 'Second', because Vue has updated the DOM
    console.log(this.$el.textContent);
  }
});

Vue.js is a progressive JavaScript framework that makes building user interfaces simple and enjoyable. Vue is designed from the ground up to be incrementally adoptable, so you can use the features you need, and mix and match Vue with other libraries or frameworks.

Vue is a relatively new framework, but it has quickly become one of the most popular JavaScript frameworks in the world. It is used by large companies like Alibaba, Baidu, and Xiaomi, as well as by thousands of smaller businesses and startups.

Here are some of the features that make Vue.js so popular:

Declarative rendering: Vue uses a declarative rendering model, which means that you can describe the desired output of your application in terms of HTML, CSS, and JavaScript. This makes it easy to reason about your code and to make changes to your application.
Reactivity: Vue is a reactive framework, which means that it automatically updates the DOM whenever there is a change to the application’s state. This makes your application feel fast and responsive.
Composition: Vue is a component-based framework, which means that you can build your application out of reusable components. This makes your code more maintainable and easier to test.
Performance: Vue is a highly performant framework. It has been benchmarked against other popular JavaScript frameworks, and it has consistently outperformed them.
