3.js代码

<script>
export default {
  props: ['catList', 'goods'],
  data() {
    return {
　　　　//和下边 <style media="printTest"> 一起的作用是去掉页眉页脚、去掉多出空白页的问题
      printObj: {
        id: 'printTest',
        popTitle: '',
        ectraHead: ''
      },
      shortData: [],
      variety: '',
      zsAll: 0, // 已检整木  总数
      woodVolumeAll: 0, // 材积
      damagedWoodAll: 0, // 断木
      notCheckWoodAll: 0, // 未检整木
      updateTime: ''
    }
  },
  methods: {
　　//这里的数据是在父页面传来的
    getvariety(variety, catList, goods) {
      this.variety = variety
      this.shortData = catListthis.goods = goods// 合计
      let zsAll = 0
      let woodVolumeAll = 0
      let damagedWoodAll = 0
      let notCheckWoodAll = 0
      this.shortData.map((item) => {
        zsAll += item.zs
        woodVolumeAll += item.woodVolume
        damagedWoodAll += item.damagedWood
        notCheckWoodAll += item.notCheckWood
      })
      this.zsAll = zsAll
      this.woodVolumeAll = woodVolumeAll
      this.damagedWoodAll = damagedWoodAll
      this.notCheckWoodAll = notCheckWoodAll
    },
  }
}
</script>
