vue显示html代码

In Vue.js, you can use the v-html directive to render HTML content dynamically. However, it's important to be cautious when using this directive, as it can expose your application to potential security vulnerabilities like cross-site scripting (XSS) attacks if you're not careful.

Here's an example of how you can use v-html in a Vue component:

html
<template>
  <div>
    <!-- Use v-html to render HTML content -->
    <div v-html="htmlContent"></div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      // HTML content to be rendered
      htmlContent: '<p>This is <strong>HTML</strong> content.</p>',
    };
  },
};
</script>

In this example, the htmlContent data property contains the HTML code that you want to render. The v-html directive is then used to bind this HTML content to the div element.

Remember to sanitize and validate any HTML content that comes from user input or external sources to prevent security issues. If you are dealing with user-generated content, consider using a library like DOMPurify to sanitize the HTML before rendering it.

Here's an example of using DOMPurify with Vue.js:

Install DOMPurify using npm:

bash
npm install dompurify

Update your Vue component:

html
<template>
  <div>
    <!-- Use v-html with sanitized content -->
    <div v-html="sanitizedHtmlContent"></div>
  </div>
</template>

<script>
import DOMPurify from 'dompurify';

export default {
  data() {
    return {
      // HTML content to be rendered
      htmlContent: '<p>This is <strong>HTML</strong> content.</p>',
    };
  },
  computed: {
    // Use a computed property to sanitize the HTML content
    sanitizedHtmlContent() {
      return DOMPurify.sanitize(this.htmlContent);
    },
  },
};
</script>

This example ensures that the HTML content is sanitized before being rendered, reducing the risk of XSS vulnerabilities.
