How to output original html in vue?

This article mainly introduces the web front-end vue to implement interpolated text and output original html. Now I share it with you and give you a reference.

Vue.js uses an HTML-based template syntax that allows developers to declaratively bind the DOM to the data of the underlying Vue instance. All Vue.js templates are legal HTML and can be parsed by browsers and HTML parsers that follow the specification.

The most common data binding in vue is text interpolation using "Mustache" syntax (double braces):

<span>Message: {{ value }}</span> // 插值文本

Whenever, the value attribute on the bound data object occurs If any changes are made, the page will be re-rendered accordingly.

Or sometimes you just want to update once and don’t want to update the data and re-render the page every time. You can also use the v-once command to achieve a one-time update:

<span v-once>这个将不会改变: {{ value }}</span> 
// value的值改变了一次后，第二次改变时就不会再重新渲染页面

Sometimes you When inserting more than a single text, such as a rich text value, it contains various text values ​​and various original HTML tags. To display it completely on the page, you must use the v-html command:

<template>
 <p v-html="htmlvalue"></p> // 调用显示富文本，将会按照原始的html显示
</template>
<script>
export default {
 data(){
 return{
  htmlvalue: &#39;<span style="color:red;">the should be red</span>&#39; // 比如：这是一个富文本的值
 }
 }
}
</script>

NOTE: Dynamically rendering arbitrary HTML on your site can be very dangerous as it can easily lead to XSS attacks. Only use HTML interpolation for trusted content and never for user-supplied content.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
