How to input html in vue

In Vue, you can use the v-html directive to insert HTML code into DOM elements.

The syntax format of the v-html directive is: "v-html = 'HTML code'". In this directive, the HTML code is an expression, which can be a data attribute of the Vue instance or a computed attribute.

The v-html directive has many usage scenarios. For example, when we need to dynamically render some content, we can use the v-html directive.

The following is an example that demonstrates how to use the v-html directive in Vue:

<template>
  <div v-html="content"></div>
</template>

<script>
export default {
  data() {
    return {
      content: '<h1>Hello world</h1>',
    }
  },
}
</script>

In this example, we define a Vue component, which uses the v-html directive to convert content The HTML code in the data attribute is inserted into the div element. The value of the content attribute defined in data is "

Hello world

".

When we run this component, the title "Hello world" will be displayed on the page. This is what the v-html directive achieves.

It should be noted that since the v-html directive will insert HTML code directly into the DOM element, you need to ensure that the HTML code is safe. If the HTML code comes from user input, some custom filters should be used to filter the HTML code to avoid cross-site scripting attacks (XSS).

In short, v-html is a very practical instruction in Vue, which can help us render page content more conveniently. However, you need to pay attention to security issues to avoid XSS attacks.
