mpvue v-for 根据变量改变值（代替filter）

根据orderStatus改变span内的值
方法一：

{{totalWords[index]}}



  data() {
    return {
      totalWords: []
    };
  },
  computed: {
    ...mapState(['allOrders']),
  },
  mounted() {
    this.createTotalWords();
  },
  methods: {
    createTotalWords() {
      const totalWords = this.allOrders.map(order => {
        if (order.orderStatus === 'unPay') {
          return '应付:';
        }
        return '合计:';
      });
      this.totalWords = totalWords;
    },
  }

方法二：

{{totalWords[item.orderStatus]}}



  data() {
    return {
      totalWords: {
        'unReceipt':'合计',
        'unConsignment':'合计',
        'unComment':'合计',
        'unPay':'应付'
      },
    };
  },
  computed: {
    ...mapState(['allOrders']),
  },
