Analysis of Mini Program Rich text
At present, Mini Program uses a lot of rich text solutions, one is the rich-text component of Mini Program, and the other is wxPrase.
The principle of wxPrase is to parse all the original html tags into Mini Program components, so that both event control and scalability are good, but it is not very good for inline rendering and multi-rendering.
Wechat's built-in rich-text component just makes up for the performance shortcomings of wxPrase inline rendering and multi-rendering, but it does not have high support for some custom tags and will block all events of the element. Although it supports direct parsing of html strings, the performance is not as good as binding json strings directly.
Rich-text demo demo given on the official website:
Page ({data: {nodes: [{name: 'div', attrs: {class:' div_class', style: 'line-height: 60px; color: red;'}, children: [{type:' text', text: 'Hello Worldwaters'}]}}, tap () {console.log ('tap')}})
Rich-text-parser is an json format that converts html strings into a json format that can be parsed by rich-text components, can customize extension tags, and supports modification of html styles (including img tags) within rich-text components.
How to use it:
