Navigating the DOM in Vue.js: A Step-by-Step Guide

Navigating the DOM in Vue.js: A Step-by-Step Guide

While I am trying to utilize Vue.js to access the DOM, the code I have written within the mounted() lifecycle is not producing any results. Interestingly enough, the same code functions perfectly fine when using vanilla JavaScript.

I have incorporated the v-html directive to inject HTML content into the span tag:

<span class="email" v-html="text"></span>

Within the mounted lifecycle block:

  mounted() {
    let images = document.getElementsByClassName(
      "mcnImageCardBottomImageContent"
    );
    console.log(images); // However, it appears to be returning an empty array
  },

Any suggestions on how to effectively access the DOM in Vue.js?

Answer №1

It is important to understand that the HTML markup you see in Vue.js or React is not traditional HTML code. Instead, it gets converted into a pure JavaScript object known as a virtual DOM.

To ensure that Vue.js renders its virtual DOM before performing certain actions, you can use this.$nextTick().

mounted() {
   this.$nextTick(() => {
      let images = document.getElementsByClassName(
        "mcnImageCardBottomImageContent"
      );
      console.log(images);
        // This currently shows an empty array
      })
}

Do you think this approach would be effective? :)

  initialized() {
    document.onreadystatechange = () => {
      if (document.readyState === "complete") {
        console.log("Page has finished loading");
        // Execute actions here
      }
    };
  }
