直接上代码了

import Taro, { Component } from '@tarojs/taro'
import { View, Button, Image, Text, ScrollView } from '@tarojs/components'
import { connect } from '@tarojs/redux'
import { bindActionCreators } from 'redux'


import * as Actions from '../../actions/counter'

import './index.scss'


function mapStateToProps(state) {
  return state
}

function mapDispatchToProps(dispatch) {
  return {
    ...bindActionCreators(Actions, dispatch)
  }
}


@connect(mapStateToProps, mapDispatchToProps)

export default class Test extends Component {

  config = {
    navigationBarTitleText: 'test'
  }

  constructor (props) {
    super(props)
    this.state = {
      items: [
        {id: 1, type: 'a', w: 100, h: 200},
        {id: 2, type: 'b', w: 200, h: 200},
      ]
    }
  }

  render () {
    var left;
    return (
      <View className='container'>
        {
            this.state.items.map((item) => {
                if(item.type == 'a') {
                    left = item.h + item.w * 2;
                    console.log(left);
                    return (
                        <View style={`width: ${Taro.pxTransform(left)};`}>
                        {left}
                        </View>
                    )
                }else if(item.type == 'b') {
                    left = item.h + item.w * 1.5;
                    console.log(left);
                    return (
                        <View style={`width: ${Taro.pxTransform(left)};`}>
                        {left}
                        </View>
                    )
                }
            })
        }
      </View>
    )
  }
}

@wasabia map 里包含 if else 判断又有中间变量,会有这个问题。。。
临时解决方案:改成 <View style={width: ${Taro.pxTransform(item.h + item.w * 2)};}>
