Detailed analysis and code examples of Vue v-html instruction (latest recommendation)

v-html is a directive in the framework that is used to dynamically render HTML code in the data to a page. It is mainly used to render some static HTML content or rich text data obtained from the background.

Using the v-html directive is very simple, just bind the HTML code you want to render into the value of the directive. Here is a simple example:

<div v-html="htmlContent"></div>

In the above example, we bind a variable named htmlContent to the v-html directive, which stores the HTML code to be rendered. The v-html directive will dynamically render this HTML code to the corresponding position of the page.

It should be noted that since the v-html directive will render HTML code in variables directly to the page, it needs to be used with caution to avoid storing malicious code in variables causing security issues.

Here is a more complete example showing how to get rich text data from the background and render it to a page:

<template>
  <div>
    <div v-html="richTextContent"></div>
    <button @click="fetchRichTextData">Get rich text data</button>
  </div>
</template>
<script>
export default {
  data() {
    return {
      richTextContent: ''
    };
  },
  methods: {
    fetchRichTextData() {
      // Simulate to get rich text data from the background      setTimeout(() => {
         = '<h1>This is a piece of rich text data</h1><p>This is a piece of rich text data</p>';
      }, 1000);
    }
  }
};
&lt;/script&gt;

In the above example, we define a variable named richTextContent to store rich text data obtained from the background. This HTML code is rendered onto the page through the v-html directive, and the fetchRichTextData method is triggered through the button click event, which simulates getting rich text data from the background and rendering it onto the page.
