How uniapp renders html template

With the rapid development of the mobile Internet, more and more companies and individuals are beginning to use mobile APPs to promote and promote products or services. In order to speed up APP development and reduce development costs, many developers choose cross-platform development frameworks, such as uniapp.

As a cross-platform application development framework based on Vue.js, uniapp can support multiple platforms such as ios, android and h5 at the same time, greatly improving development efficiency. However, since front-end development involves a lot of HTML page rendering, how to implement it specifically?

Today, let’s talk about how uniapp renders HTML templates.

1. Use the vue-html-to-paper plug-in

vue-html-to-paper is a very easy-to-use Vue.js plug-in that can convert HTML into PDF files and print it out. Using it in uniapp, you can convert HTML templates into PDF files, and then render the PDF files into pages through uniapp's API. In actual use, you can customize settings according to business needs, such as font size, color, margins, Page numbers etc.

Usage:

1. Install vue-html-to-paper plug-in

npm install vue-html-to-paper

2. Introduce the plug-in into the main.js file of the uniapp project and set global properties

import VueHtmlToPaper from 'vue-html-to-paper';
Vue.use(VueHtmlToPaper) ;

3. Write HTML template in component

4. Set the print event in the component's methods

methods: {
printTemplate () {

this.$htmlToPaper('.htmlTemplate');

}
}

5. Add a print button to the page and bind the print event

2. Use the rich-text component that comes with uniapp

There is a rich-text component in uniapp, which can parse rich text content and then render it into an HTML page. In the render parameter data, if there is an html field, all codes inside it will be parsed, processed and rendered into rich text content.

Usage:

1. Write an HTML template and store it in a database or JSON file

{
"title": " This is an HTML template",
"content": "

This is a title

This is a piece of text

"
}

2. Introduce data into the component and use the rich-text component Rendering

<script><br> export default {</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">data () {   return {     template: {}   } }, mounted () {   // 在实际使用中，可以将数据从数据库或JSON文件中获取，并赋值给template   this.template = {     &quot;title&quot;: &quot;这是一个HTML模板&quot;,     &quot;content&quot;: &quot;&lt;div&gt;&lt;h1&gt;这是一个标题&lt;/h1&gt;&lt;p&gt;这是一段文字&lt;/p&gt;&lt;img src=&amp;#39;../../static/logo.png&amp;#39; alt=&amp;#39;&amp;#39;&gt;&lt;/div&gt;&quot;   } }</pre><div class="contentsignin">Copy after login</div></div> <p>}<br></script>

Summary:

The above two methods have their own advantages and disadvantages. Use the vue-html-to-paper plug-in to convert HTML templates into PDF files, and customize settings according to business needs to make the rendering effect more perfect. Using the rich-text component that comes with uniapp, you can directly render the HTML template into rich text content. The rendering speed is faster, but it is a bit crude. Depending on specific business needs, developers can choose to use different methods.

No matter which method is used, HTML template rendering is a very common requirement in mobile APPs. Mastering the correct methods and techniques can help developers quickly implement HTML template rendering and bring a better user experience.
