<template>
  <div class="end_judging_scrap_steel">
    <t-header title="废钢终判" :back="goBack">

<script>
export default {
  name: 'endJudgingScrapSteel',
  data() {
    return {
     
    }
  },
  beforeDestroy() {
    window.removeEventListener('popstate', this.goBack, false)
  },
  mounted() {
    if (window.history && window.history.pushState) {
      // 向历史记录中插入了当前页
      history.pushState(null, null, location.href)
      window.addEventListener('popstate', this.goBack, false)
    }
  },
  methods: {
    goBack() {
      this.$router.push({ path: '/' });
    }
  },
};
