【微信小程序开发】 wxParse组件

html2json.js　 //将html每个标签转化成DOM对象的node
htmlparse.js   //由html2json.js引用
showdown.js    //由wxParse.js引用
wxDiscode.js   //支持的符号库 
wxParse.js     //主入口的js，和处理各种标签的事件，如图片的onload
wxParse.wxml   //不同标签template组件，内容会循环成HTML的DOM对象，每个都转化成template，显示出来
wxParse.wxss 　//样式

//引用

var WxParse = require(‘/wxParse/wxParse.js‘);

//将需要转化的内容加上
var that=this;
WxParse.wxParse(‘Content1‘, ‘html‘, 内容, that, 0);

<template is="wxParse" data="{{wxParseData:Content1.nodes}}"/>

@import "/wxParse/wxParse.wxss";

//图片的onload事件

  var tagFrom = e.target.dataset.from;
  var idx = e.target.dataset.idx;
  if (typeof (tagFrom) != ‘undefined‘ && tagFrom.length > 0) {
    calMoreImageInfo(e, idx, that, tagFrom)
  } 
}

// 循环获取计算图片视觉最佳宽高
function calMoreImageInfo(e, idx, that, bindName) {
  var temData = that.data[bindName];
  if (!temData || temData.images.length == 0) {
    return;

  //给图片真实宽高,通过styleStr 20191128 S
  var recal = wxAutoImageCal(e.detail.width, e.detail.height, that, bindName); 
  var temImages = temData.images;//获取里面的images对象
  //给styleStr赋值
